Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. squid3-3.5.12/CREDITS000066400000000000000000002473101262763202500140460ustar00rootroot00000000000000This file contains copyright and licensing information for 3rd party software imported into Squid.

Most commonly this is * accomplished by including a link to the Harvest Home Page * (http://harvest.cs.colorado.edu/) from the query page of any * Broker you deploy, as well as in the query result pages.

We assume * no liability with respect to the infringement of copyrights, * trade secrets, or any patents, and are not responsible for * consequential damages. Proper use of the Harvest software is * entirely the responsibility of the user. * * DERIVATIVE WORKS * * Users may make derivative works from the Harvest software, subject * to the following constraints: * * - You must include the above copyright notice and these * accompanying paragraphs in all forms of derivative works, * and any documentation and other materials related to such * distribution and use acknowledge that the software was * developed at the above institutions. * * - You must notify IRTF-RD regarding your distribution of * the derivative work. * * - You must clearly notify users that your are distributing * a modified version and not the original Harvest software. * * - Any derivative product is also subject to these copyright * and use restrictions. * * Note that the Harvest software is NOT in the public domain. We * retain copyright, as specified above. * * HISTORY OF FREE SOFTWARE STATUS * * Originally we required sites to license the software in cases * where they were going to build commercial products/services * around Harvest. In June 1995 we changed this policy. We now * allow people to use the core Harvest software (the code found in * the Harvest ``src/'' directory) for free. We made this change * in the interest of encouraging the widest possible deployment of * the technology. The Harvest software is really a reference * implementation of a set of protocols and formats, some of which * we intend to standardize. We encourage commercial * re-implementations of code complying to this set of standards. */ ============================================================================== acinclude/ax_cxx_0x_types.m4: ## ## AX_CXX_TYPE_NULLPTR shamelessly copied from the DUNE sources under GPL version 2 ## ============================================================================== acinclude/ax_cxx_compile_stdcxx_11.m4: # Copyright (c) 2008 Benjamin Kosnik # Copyright (c) 2012 Zack Weinberg # Copyright (c) 2013 Roy Stogner # Copyright (c) 2014 Alexey Sokolov # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.

Older ChangeLog follows. The sections relating to Squid-2.6 is not entirely authorative for this release and mirrored here for reference only. - CARP now plays well with the other peering algorithms, and support for CARP peerings is compiled by default. Can be disabled by --disable-carp - Configuration file can be read from an external program or preprocessor.

The fix for this also adds the ability to send redirects. Changes to squid-2.5.STABLE2 (Mars 17, 2003): - Contrib files added back to the distribution - Several compiler warnings fixed when using --disable-ident or --disable-http-violations - authentication can now be used in most access controls, but must in most cases first be enforced in http_access to force the user to authenticate. - cleanups in the developer bootstrap.sh process when preparing the sources. - several squid.conf.default documentation updated to correctly refer to the current names when refering to other directives - authenticate_ip_ttl documentation updates - several assertion faults and segmentation violations corrected - the RunCache/RunAccel and squid.rc scripts updated to refer to the squid binary in sbin rather than the old bin location. - squid_ldap_auth command line processing fixes when specifying the LDAP server last on the line instead of -h option - aufs data corruption bugfix - aufs performance improvement for low traffic systems - aufs stability improvements - external_acl corrected to properly deal with quoted strings - WCCPv1 bugfix to make sure the router accepts the hash assignments - "Total accounted memory" now correctly reported in cachemgr - several small memory leaks (mostly reconfigure related) - new squid.conf option to allow GET/HEAD requests with a request entity - "make uninstall" no longer removes squid.conf - cachemgr.cgi now uses POST to avoid having the cachemgr password logged in the web server logs - authentication schemes which are known to not be proxyable are now filtered out from forwarded server replies to avoid that the clients tries to use such schemes when we know for a fact it won't work - spelling corrections in various error messages - now possible to define acl values with spaces in them by using the "include file" feature - squid_ldap_group updated to 2.10 to fix compilation issues with recent (and older) OpenLDAP libraries and to make the helper deal correctly with true LDAP groups by first looking up the user DN. - Some internal code cleanups - now verifies that programs etc exists iside the chroot directory when using chroot_dir. No longer neccesary to set up a split view environment where the same paths works both inside the chroot and outside just to convince Squid that the files is actually there.. - improved memory usage reporting - --disable-hostname-checks configure option - no longer ignores double dots in host names. Any hostname with double dots is now rejected as invalid. - log_mime_hdrs no longer logs garbage if very long headers are seen. - 'select_fds_hist' object added to cachemgr 'histogram' output - pid file now unlinked when squid has really shut down, not immediately when the shutdown request is received. This allows the pid file to be monitored to determine when Squid has shut down properly - correct authentication scheme setups on some platforms or compilers - several squid.conf.default documentation updates to remove references to renamed or replaced directives by changing them to their current names. - the SSL reverse proxy support updated to allow building with OpenSSL 0.9.7 and and later. - Corrected a minor performance problem while processing HEAD replies from various broken web servers not sending a correct HTTP reply - time acls can now specify multiple times in the same acl name, like most other acl types. - winbind helpers updated to match Samba-2.2.7a and should work with Samba-2.2.6 or later (required). For compability with older Samba versions A new configure option --with-samba-sources=... has been added to allow you to specify which Samba version the helpers should be built for if different than the above versions. - Squid MIB definition syntax correction to work better with newer (and older) SNMP tools. - Fixed access.log format when logging "error:invalid-HTTP-ident" on requests where parsing the HTTP identifier (HTTP/1.0) failed. - "make distclean" no longer removes the icons, this avoids the dependency on "uudecode" to rebuild Squid after "make distclean" - User name returned by external acl lookups (external_acl_type) is now available as "ident" in later acl checks in addition to the logging in access.log. - Incorrect behaviour of Digest authentication partly corrected - it will not handle sessions, but will always enforce password correctness.. (patch submitted by Sean Burford). - Issue with persistent connections and PUT/POST request corrected Changes to squid-2.5.STABLE1 (September 25, 2002): - Major rewrite of proxy authentication to support other schemes than basic. First in the line is NTLM support but others can easily be added (minimal digest is present). See Programmers Guide. (Robert Collins & Francesco Chemolli) - Reworked how request bodies are passed down to the protocols. Now all client side processing is inside client_side.c, and the pass and pump modules is no longer used. used by Squid. - Optimized searching in proxy_auth and ident ACL types. Squid should now handle large access lists a lot more efficiently. (Francesco Chemolli) - Fixed forwarding/peer loop detection code (Brian Degenhardt) - now a peer is ignored if it turns out to be us, rather than committing suicide - Changed the internal URL code to obey appendDomain for internal objects if it needs appending. This fixes weirdnesses where a machine can think it is "foo.bar.com", and "foo" is requested. (Brian Degenhardt) - Added the use of Automake to create the Makefile.in's in the squid source tree. This will allow libtool in the future, and immediately allows better dependency tracking - with or without gcc - as well as the dist-all and distcheck targets for developers which respectively build a tar.gz and a tar.bz2 distribution, and check that what will be distributed builds. - Added TOS and source address selection based on ACLs, written by Roger Venning. This allows administrators to set the TOS precedence bits and/or the source IP from a set of available IPs based upon some ACLs, generally to map different users to different outgoing links and traffic profiles. - Added 'max-conn' option to 'cache_peer' - Added SSL gatewaying support, allowing Squid to act as a SSL server in accelerator setups. - SASL authentication helper by Ian Castle - msntauth updated to v2.0.3 - no_cache now applies to cache hits as well as cache misses - the Gopher client in Squid has been significantly improved - Squid now sanity checks FTP data connections to ensure the connection is from the requested server. Can be disabled if needed by turning off the ftp_sanitycheck option. - external acl support. A mechanism where flexible ACL checks can be driven by external helpers. See the external_acl_type and acl external directives. - Countless other small things and fixes - HTML pages generated by Squid or CacheMgr as well as the ERR documents now contain a doctype declaration so that browsers know which HTML specification the document uses. In addition to that they have a new look (background-color, font) and are valid according to the HTML standards at www.w3.org. (Clemens L ser) - Login and password send to Basic auth helpers is now URL escaped to allow for spaces and other "odd" characters in logins and passwords - Proxy Authentication is no longer blindly forwarded to peer caches if not used locally. If forwarding of proxy authentication is desired then it must now be configured with the login=PASS cache_peer option. - Responses with Vary: in the header are now cached by squid. (Henrik Nordstrom). - Removed unused 'siteselect_timeout' directive. Changes to Squid-2.4.STABLE7 (July 2, 2002): - Squid now drops any requests using transfer-encoding. Squid is a HTTP/1.0 proxy and as such do not support the use of transfer-encoding. - The MSNT auth helper has been updated to v2.0.3+fixes for buffer overflow security issues found in this helper. - A security issue in how Squid forwards proxy authentication credentials has been fixed - Minor changes to support Apple MAC OS X and some other platforms more easily. - The client -T option has been implemented - HTCP related bugfixes in "squid -k reconfigure" - Several bugfixes and cleanup of the Gopher client, both to correct some security issues and to make Squid properly render certain Gopher menus. - FTP data channels are now sanity checked to match the address of the requested FTP server. This to prevent theft or injection of data. See the new ftp_sanitycheck directive if this is not desired. - Security fixes in how Squid parses FTP directory listings into HTML Changes to Squid-2.4.STABLE6 (March 19, 2002): - The patch for 2.4.STABLE5 was insufficiently tested and introduced a bug that causes frequent assertions when handling DNS PTR answers. Changes to Squid-2.4.STABLE5 (March 15, 2002): - Fixed an array bounds bug in lib/rfc1035.c. This bug could allow a malicious DNS server to send bogus replies and corrupt the heap memory. Changes to Squid-2.4.STABLE4 (Feb 19, 2002) - htcp_port 0 now properly disables htcp - Fixed problem with certain non-anonymous ftp:// style URL's - SNMP bugfixes including several memory leaks Changes to Squid-2.4.STABLE3 (Nov 28, 2001): - Fixed bug #255: core dump on SSL/CONNECT if access denied by miss_access - Fixed bug #246: corrupt on-disk meta information preventing rebuilds of lost swap.state files - Fixed bug #243: squid_ldap_auth now supports spaces in passwords - Fixed a coredump when creating FTP directories - Fixed a compile time problem with statHistDump prototype mistmatch, reported by some compilers - Fixed a potential coredump situation on snmpwalk in certain configurations - Fixed bug #229: filedescriptor leakage in the "aufs" cache_dir store implementation - Serbian error message translations Changes to Squid-2.4.STABLE2 (Aug 24, 2001): - Expanded configure's GCC optimization disabling check to include GCC 2.95.3 - avoid negative served_date in storeTimestampsSet(). - Made 'diskd' pathnames more configurable - Make sure squid parent dies if child is killed with KILL signal - Changed diskd offset args to off_t instead of int - Fixed bugs #102, #101, #205: various problems with useragent log files - Fixed bug #116: Large Age: values still cause problems - Fixed bug #119: Floating point exception in storeDirUpdateSwapSize() - Fixed bug #114: usernames not logged with authenticate_ip_ttl_is_strict - Fixed bug #115: squid eating up resources (eventAdd args) - Fixed bug #125: garbage HTCP requests cause assertion - Fixed bug #134: 'virtual port' support ignores httpd_accel_port, causes a loop in httpd_accel mode - Fixed bug #135: assertion failed: logfile.c:135: "lf->offset <= lf->bufsz" - Fixed bug #137: Ranges on misses are over-done - Fixed bug #160: referer_log doesn't seem to work - Fixed bug #162: some memory leaks (SNMP, delay_pools, comm_dns_incoming histogram) - Fixed bug #165: "Store Mem Buffer" leaks badly - Fixed bug #172: Ident Based ACLs fail when applied to cache_peer_access - Fixed bug #177: LinuxPPC 2000 segfault bug due to varargs abuse - Fixed bug #182: 'config' cachemgr option dumps core with null storage - Fixed bug #185: storeDiskdDirParseQ[12]() use wrong number of args in debug/printf - Fixed bug #187: bugs in lib/base64.c - Fixed bug #184: storeDiskdShmGet() assertion; changed diskd to use bitmap instead of linked list - Fixed bug #194: Compilation fails on index() on some non-BSD platforms - Fixed bug #197: refreshIsCachable() incorrectly checks entry->mem_obj->reply - Fixed bug #215: NULL pointer access for proxy requests in accel-only mode Changes to Squid-2.4.STABLE1 (Mar 20, 2001): - Fixed a bug in and cleaned up class 2/3 delay pools incrementing. - Fixed a coredump bug when using external dnsservers that become overloaded. - Fixed some NULL pointer bugs for NULL storage system when reconfiguring. - Fixed a bug with useragent logging that caused Squid to think the logfile never got opened. - Fixed a compiling bug with --disable-unlinkd. - Changed src/squid.h to always use O_NONBLOCK on Solaris if it is defined. - Fixed a bug with signed/unsigned bitfield flag variables that caused problems on Solaris. - Fixed a bug in clientBuildReplyHeader() that could add an Age: header with a negative value, causing an assertion later. - Fixed an SNMP reporting bug. cacheCurrentResFileDescrCnt was returning the number of FDs in use, rather than the number of reserved FDs. - Added the 'pipeline_prefetch' configuration option. - cache_dir syntax changed to use options instead of many arguments. This means that the max_objsize argument now is an optional option, and that the syntax for how to specify the diskd magics is slightly different. - Various fixes for CYGWIN - Upgraded MSNT auth module to version 2.0. - Fixed potential problems with HTML by making sure all HTML output is properly encoded. - Fixed a memory initialization problem with resource records in lib/rfc1035.c. - Rewrote date parsing in lib/rfc1123.c and made it a little more lenient. - Added Cache-control: max-stale support. - Fixed 'range_offset_limit' again. The problem this time is that client_side.c wouldn't set the we_dont_do_ranges flag for normal cache misses. It was only being set for requests that might have been hits, but we decided to change to a miss. - Added the Authenticate-Info and Proxy-Authenticate-Info headers from RFC 2617. - HTTP header lines longer than 64K could cause an assertion. Now they get ignored. - Fixed an IP address scanning bug that caused "123.foo.com" to be interpreted as an IP address. - Converted many structure allocations to use mem pools. - Changed proxy authentication to strip leading whitespace from usernames after decoding. - Prevented NULL pointer access in aclMatchAcl(). Some ACL types require checklist->request_t, but it won't be available in some cases (like snmp_access). Warn the admin that the ACL can't be checked and that we're denying it. - Allow zero-size disk caches. - The actual filesystem blocksize is now used to account for space overheads when calculating on-disk cache size. - Made the maximum memory cache object size configurable. - Added 'minimum_direct_rtt' configuration option. - Added 'ie_refresh' configuration option, which is a hack to turn IMS requests into no-cache requests. - Added support for netfilter in linux-2.4. This allows transparent proxy connections to function correctly in the absence of a Host: header. This requires --enable-linux-netfilter to be passed through to configure. (Evan Jones) - Fixed a bug with clientAccessCheck() that allowed proxy requests in accel mode. - Fixed a bug with 301/302 replies from redirectors. Now we force them to be cache misses. - Accommodated changes to the IP-Filter ioctl() interface for intercepted connections. - Fixed handling of client lifetime timeouts. - Fixed a buffer overflow bug with internal DNS replies by truncating received packets to 512 bytes, as per RFC 1035. - Added "forward.log" support, but its work in progress. - Rewrote much of the IP and FQDN cache implementation. This change gets rid of pending hits. - Changed peerWouldBePinged() to return false if our ICP/HTCP port is zero (i.e. disabled). - Changed src/net_db.c to use src/logfile.c routines, rather than stdio, because of solaris stdio filedescriptor limits. - Made netdbReloadState() more robust in case of corrupted data. - Rewrote some freshness/staleness functions in src/refresh.c, partially inspired to support cache-control max-stale. - Fixed status code logging for SSL/CONNECT requests. - Added a hack to subtract cache digest network traffic from statistics so that byte hit ratio stays positive and more closely reflects what people expect it to be. - Fixed a bug with storeCheckTooSmall() that caused internal icons and cache digests to always be released. - Added statfs(2) support for displaying actual filesystem usage in the cache manager 'storedir' output. - Changed status reporting for storage rebuilding. Now it prints percentage complete instead of number of entries parsed. - Use mkstemp() rather than problem-prone tempnam(). - Changed urlParse() to condense multiple dots in hostnames. - Major rewrite of async-io (src/fs/aufs) to make it behave a bit more sane with substantially less overhead. Some tuning work still remains to make it perform optimal. See the start of store_asyncufs.h for all the knobs. - Fixed storage FS modules to use individual swap space high/low values rather than the global ones. - Fixed storage FS bugs with calling file_map_bit_reset() before checking the bit value. Calling with an invalid value caused memory corruption in random places. - Prevent NULL pointer access in store_repl_lru.c for entries that exist in the hash but not the LRU list. Changes to Squid-2.4.DEVEL4 (): - Added --enable-auth-modules=... configure option - Improved ICP dead peer detection to also work when the workload is low - Improved TCP dead peer detection and recovery - Squid is now a bit more persistent in trying to find a alive parent when never_direct is used. - nonhierarchical_direct squid.conf directive to make non-ICP peer selection behave a bit more like ICP selection with respect to hierarchy. - Bugfix where netdb selection could override never_direct - ICP timeout selection now prefers to use parents only when calculating the dynamic timeout to compensate for common RTT differences between parents and siblings. - No longer starts to swap out objects which are known to be above the maximum allowed size. - allow-miss cache_peer option disabling the use of "only-if-cached". Meant to be used in conjunction with icp_hit_stale. - Delay pools tuned to allow large initial pool values - cachemgr filesystem space information changed to show useable space rather than raw space, and platform support somewhat extended. - Logs destination IP in the hierarchy log tag when going direct. (can be disabled by turning log_ip_on_direct off) - Async-IO on linux now makes proper use of mutexes. This fixes some odd pthread segfaults on SMP Linux machines, at a slight performance penalty. - %s can now be used in cache_swap_log and will be substituted with the last path component of cache_dir. - no_cache is now a full ACL check without, allowing most ACL types to be used. - The CONNECT method now obeys miss_access requirements - proxy_auth_regex and ident_regex ACL types - Fixed a StoreEntry memory leak during "dirty" rebuild - Helper processes no longer hold unrelated filedescriptors open - Helpers are now restarted when the logs are rotated - Negatively cached DNS entries are now purged on "reload". - PURGE now also purges the DNS cache - HEAD on FTP objects no longer retrieves the whole object - More cleanups of the dstdomain ACL type - Squid no longer tries to do Range internally if it is not supported by the origin server. Doing so could cause bandwidth spikes and/or negative hit ratio. - httpd_accel_single_host squid.conf directive - "round-robin" cache_peer counters are reset every 5 minutes to compensate previously dead peers - DNS retransmit parameters - Show all FTP server messages - squid.conf.default now indicates if a directive isn't enabled in the installed binary, and what configure option to use for enabling it - Fixed a temporary memory leak on persistent POSTs - Fixed a temporary memory leak when the server response headers includes NULL characters - authenticate_ip_ttl_is_strict squid.conf option - req_mime_type ACL type - A reworked storage system that supports storage directories in a more modular fashion. The object replacement and IO is now responsibility of the storage directory, and not of the storage manager. - Fixed a bogus MD5 mismatch warning sometimes seen when using aufs or diskd stores - Added --enable-stacktraces configure option to set PRINT_STACK_TRACE, and extended support for this to Linux/GNU libc. - Disabled the "request timeout" error message sent if the user agent did not provide a request in a timely manner after opening the connection. Now the connection is silently closed. The error message was confusing user agents utilizing persistent connections. - Fixed configure --enable descriptions to match the arg names. - Eliminated compile warnings from auth_modules/MSNT code. - Require first character of hostnames to be alphanumeric. - Made ARP ACL work for Solaris. - Removed storeClientListSearch(). - Added counters to track diskd operation success and failures. - Fixed range_offset_limit. - Added code to retry ServFail replies for internal DNS lookups. - Added referer header logging (Jens-S. Voeckler). - Added "multi-domain-NTLM" authentication module, a Perl script from Thomas Jarosch. - Added configurable warning messages for high memory usage, high response time, and high page faults. - Made store dir selection algorithm configurable. - Added support for admin-definable extension methods, up to 20. - Added 'maximum_object_size_in_memory' as a configuration option - this defines the watermark where objects transit from being true hot objects to being in-transit objects in memory. It currently defaults to 8 KB. - Change to the fqdn code which changes how pending DNS requests are treated as private and only become public once they are completed. This can add extra load on DNS servers but prevents all the pending clients blocking if one of the queries got stuck. (Duane Wessels) - Converted more code to use MemPools, from Andres Kroonmaa. - Added more CYGWIN patches from Robert Collins. Changes to Squid-2.4.DEVEL3 (): - Added Logfile module. - Added DISKD stats via cachemgr. - Added squid.conf options for DISKD magic constants. Changes to Squid-2.4.DEVEL2 (Feb 29, 2000): Changes to Squid-2.4.DEVEL1 (): Changes to Squid-2.3.STABLE4 (July 18, 2000): - Fixed --localstatedir configure option (IKEDA Shigeru). - Fixed IPFilter headers on OpenBSD (Nic Bellamy, Brad Smith). - Added pthread_sigmask() check to configure (Daniel Ehrlich). - Added CYGWIN patches from Robert Collins. - Changed internal DNS lookups to retry queries that are returned with RCODE 2 (ServFail). - Added 'virtual port' support (Gregg Kellogg). If 'httpd_accel_uses_host_header' is enabled, then we use the port number from the Host header. Otherwise, when 'httpd_accel_port' is set to "0" we use the port number of the local end of the client socket. - Fixed a typo in carp.c (Nikolaj Yourgandjiev). - Made Squid accept GET requests that have a "content-length: 0" header. - Added a sanity check on the NHttpSockets[] array index (Gregg Kellogg). - Added a friendlier message when Squid can't find any DNS nameserver addresses to use (Daniel Kiracofe). - Added nonstandard WEBDAV methods: BMOVE, BDELETE, BPROPFIND (Craig Whitmore). - Added missing '%c' token replacement in error page generation. - Fixed a bug with 'minimum_object_size' that prevented internal icons from being loaded. - Fixed "extra semicolon" bug in storeExpiredReferenceAge() that could prevent any objects from being replaced. - Make sure that storeDirDiskFull() doesn't actually *increase* the cache size. - Changed a storeSwapMetaUnpack() assertion to a recoverable error condition. - Removed "wccpHereIam" event check that could cause Squid to stop sending HERE_I_AM messages. Changes to Squid-2.3.STABLE3 (May 15, 2000): - Fixed malloc linking problems on Solaris. The configure script incorrectly set options for dlmalloc. - Added a configure check to remove compiler optimization for GCC 2.95.x. - Updated MSNT authenticator module. - Updated Estonian error pages. - Updated Japanese error pages. - Fixed expires bug in httpReplyHdrCacheInit. It was incorrectly setting expires based on max-age. It was using the current time as a basis, instead of the response date. - Fixed "USE_DNSSERVER" typos. - Added a workaround for getpwnam() problems on Solaris. getpwnam() could fail if there are fewer than 256 FDs available. This causes root to own some disk files. - Added an 'offline_toggle' option via the cache manager. - Added a 'minimum_object_size' option. Files smaller than this size are not stored. - Added 'passive_ftp' option to disable passive FTP transfers. - Added 'wccp_version' option because some Cisco IOS versions require WCCP version 3. - The 'client' program in ping mode (-g) now prints transfer throughput. - Fixed logging of proxy auth username for redirected requests. - Fixed bogus Age values for IMS requests. - Fixed persistent connection timeout for client-side connections. It was hard-coded to 15 seconds, now uses the 'pconn_timeout' value. - Fixed up httpAcceptDefer. It wasn't being used properly and caused high CPU usage when Squid gets close to the FD limit. - Numerous delay_pools fixes and checks. - Fixed SNMP coredumps from running snmpwalk. - Added a check for errno == EPIPE in icmp.c when pinger uses a Unix socket instead of a UDP socket. - Fixed ACL checklist memory initialization bugs. - Cleaned up the MIB file. Replaced contact information and checked description fields. - Removed LRU reference_age hard-coded upper limit. - Fixed async I/O FD leak. - Made getMyHostname() more robust. - Fixed domain list matching bug. "x-foo.com" wasn't properly compared to ".foo.com" and confused splay tree ordering. - Added a check for whitespace in hostnames and optionally strip whitespace if 'uri_whitespace' setting allows. - Added status code and checking to ASN/whois queries. Changes to Squid-2.3.STABLE2 (Mar 2, 2000): - Changed Copyright text. - Changed configure so that some IRIX-6.4 hacks apply to all IRIX-6.* versions. - Cleaned up HTML bugs in error pages. - Told configure to check for netinet/if_ether.h, which is used in ARP ACL code, but might not be required. - Added "Cookie" to known HTTP headers so it can be used in anonymizer configuration. - Added optional TCP_REDIRECT log code for logging of 301/302 responses returned by Squid. - Added a check for a currently running Squid process. If the pid file exists, and the pid is running, Squid complains and refuses to start another instance. - Changed async I/O scope to PTHREAD_SCOPE_PROCESS for IRIX. - Fixed a bug with the PURGE method. The purge enable flag was not getting cleared during reconfigure. Also required PURGE method to be used in http_access list before enabling. - Fixed async I/O assertions for file open errors. - Fixed internal DNS assertion when unpacking truncated messages. - Fixed anonymize_headers bug that caused all headers to be allowed after a reconfigure. - Fixed an access denied bug for accelerator-only installations. - Fixed internal DNS initialization so that it uses 'dns_nameservers' settings in squid.conf if set. - Fixed 'maxconn' ACL bug that caused it to work backwards (Pedro Ribeiro). - Fixed syslog bug for daemon mode on Linux. - Fixed 'http_port' parsing bugs. - Fixed internal DNS byte ordering bugs for PTR queries. - Fixed internal DNS queue getting stuck during periods of low activity (Henrik). - Fixed byte ordering bugs for parsing EPLF FTP listings on 64-bit systems. - Fixed 'request_body_max_size' bug that caused all POST, PUT requests to be denied if max size is set to zero. - Fixed 'redirector_access' bug when using 'myport' ACLs. - Fixed CARP neighbor selection bugs for down peers. - Added 'client_persistent_connections' and 'server_persistent_connections' flags to disable persistent connections for clients and servers. - Fixed access logging bug that caused many requests to be logged as TCP_MISS. - Added some bounds checking to delay pools code. Changes to Squid-2.3.STABLE1 (Jan 9, 2000): - Updated PAM authentication module from Henrik Nordstrom. - Updated Bulgarian error messages from Svetlin Simeonov. - Changed ACL routines so that User-Agent (browser) string is always taken from compiled HTTP request headers instead of passed as an argument to aclCreateChecklist. - Added a 'strip' option to the 'uri_whitesace' configuration directive and made it the default behavior. Whitespace found in URI's is now stripped out by default. - Added chroot feature. The 'chroot_dir' config option enables it and specifies the directory. - Changed clientBuildReplyHeader so that the Age header is added only for cache hits, and only when we can calculate a valid, positive age value. - Changed clientWriteComplete and clientGotNotEnough so that they keep persistent connections open for more types of replies that don't have bodies. - Changed filemap.c routines to dynamically grow filemap space as needed. - Added a hack to ftp.c to deal with ftp.netscape.com, which sometimes doesn't acknowledge PASV commands. - Fixed FTP bug with ftpScheduleReadControlReply; there was not always a timeout handler on the control socket after the transfer completed. - Fixed FTP filedescriptor leak from invalid PASV replies. - Changed httpBuildRequestHeader so that it doesn't copy the Host header from the client request. Instead we should generate our own Host header which is known to be correct. - Changed storeTimestampsSet to adjust entry->timestamp if the response includes an Age header. - Removed size limit from storeKeyHashBuckets. - Changed fwdConnectStart from a "heavy" to a "light" event. - Fixed an 'anonymize_headers' bug that affects unknown HTTP headers. With the bug, if you list a header that Squid doesn't know about (such as "Charset"), it would add HDR_OTHER to the allow/deny mask. This caused all unknown headers to be allowed or denied (depending on the scheme you use). Now, with the bug fixed, an unknown header in the 'anonymize_headers' list is simply ignored. Changes to Squid-2.3.DEVEL3 (): - Added MSNT auth module from Antonino Iannella. - Added --enable-underscores configure option. This allows Squid to accept hostnames with underscores in them. Your DNS resolver may still complain about them, however. - Added --heap-replacement configure option. This enables the alternative cache replacement policies, such as GDSF, and LFUDA. - WCCP establishes and registers with the router faster. - Added 'maxconn' acl type to limit the number of established connections from a single client IP address. Submitted by Vadim Kolontsov. - Close FTP data socket as soon as transfer completes (Alexander V. Lukyanov). - Fixed ftpReadPass() to not clobber ctrl.message when the PASS command fails. - Added a redirect.c patch so squidGuard is able to do per-user access control (Antony T Curtis). - discard the pumpMethod() function, and instead use the fact that the request has a request entity (content-length present) (Henrik). - Reload the MIME icons at reconfigure time (Radu Greab). - Updated Richard Huveneers' SMB authentication module to his version 0.05 package. - Fixed lib/heap.c::heap_delete() bug when deleting the last node. - Fixed an integer conversion bug in lib/rfc1035.c::rfc1035AnswersUnpack(). - Fixed lib/rfc1738 routines to encode reserved characters, in addition to encoding the unsafe characters (Henrik). - Changed the interface for splay compare and "walk" functions to take a void pointer, instead of a splayNode pointer (Henrik). - Changed numerous HTTP parsing routines to use ssize_t instead of size_t. This was done because size_t may be signed or unsigned. When it is unsigned, gcc emits numerous "comparison is always true" warnings. At least we know ssize_t is always signed. - Fixed src/HttpHeaderTools::httpHeaderHasConnDir() and friends so that it properly handles multi-value lists. - Added an "end" (ssize_t) parameter to src/HttpReply::httpReplyParse() so that we know exactly where to terminate the header buffer. - Changed src/access_log.c::log_quote() so that it only encodes whitespace characters, and not all URL-special characters (Henrik). - Added local port ACL type ("myport") (Henrik). - Added maximum number of connections per client ("maxconn") as an ACL type. - Fixed proxy authentication username/password parsing to be more robust (Henrik). - Fixed ACL domain/host and domain/domain comparison functions yet again. Eliminated duplicate code so that only src/url.c::matchDomainName() contains this mysterious code. - Changed the 'http_port' option to accept an IP address or hostname as well (Henrik). - Removed 'tcp_incoming_addr' option. - Added an access control list for the redirector ('redirector_access'). Requests which match are sent to the redirector. All requests. are redirected by default. - Added the 'authenticate_ip_ttl' option. It specifies how long a valid proxy authentication credential is bound to a specific address. - Added 280, 488, 591, and 777 to "Safe_ports" ACL. - Removed the unused and highly questionable 'forward_snmpd_port' option. - Added an option to accept DNS messages from unknown nameservers. This may be necessary if replies come from a different address than queries are sent to. - Added #includes for IP Filter files in netinet directory. - Fixed a bug with retrying forwarded IMS requests (Henrik). - Fixed a bug in src/client_side.c::clientInterpretRequestHeaders() where we were checking a cache-control bit before getting the mask from the HTTP headers (pallo@initio.no). - Fixed a bug with "no_cache" access list. If not defined, everything was uncachable by default. - Fixed a bug with timed-out client-side HTTP connections. We didn't cancel the read handler, which could lead to "rwstate != NULL" warnings. - Changed comm_open() to only call fdAdjustReserved() for specific errors (ENFILE, EMFILE); - Fixed NULL pointer bug in idnsParseResolvConf(). - Split CACHE_DIGEST_HIT into CD_PARENT_HIT and CD_SIBLING_HIT. - Added DELETE request method. - Added RFC 2518 HTTP status codes. - Fixed handling of URL passwords when we need to rewrite a BASE HREF URL (Henrik). - Fixed a bug with FTP requests where a request gets aborted, but we try to complete it anyway. It would result in a "store_status != STORE_PENDING" assertion. The solution is to check for ENTRY_ABORTED before reading from the control channel too. - Changed FTP to retry a request if Squid fails to establish a PASV data connection (Henrik). - Fixed numerous HTCP memory leaks and an uninitialized memory bug. - Changed httpMaybeRemovePublic() with RFC 2518 and 2616 in mind (Henrik). - Minor fixes for Rhapsody systems. - Define _XOPEN_SOURCE_EXTENDED in squid.h so that AIX systems don't include varargs.h. - Changed src/store_client.c::storeClientType() so that an entry can have more than one STORE_MEM_CLIENT. - Changed src/store_client.c::storeClientReadHeader() to check swapfile metadata (Henrik). - Changed src/url.c::urlCheckRequest() to return FALSE for any "https://" URL. These should always be CONNECT instead. If Squid gets an "https://" URL, it is a browser bug. - Added numerous squid.conf options for controlling cache digests. Previously these were hard-coded in src/store_digest.c. (Martin Hamilton) - Added 'cache_peer' option called 'digest-url' that lets you specify the URL for a peer's digest. (Martin Hamilton) - Added DELAY_POOLS hacks to scan "slow" connections in a random order (David Luyer). - ARP_ACL fixes from Damien Miller. Linux 2.2.x uses a per-interface arp/neighbour cache, whereas 2.0.x uses a unified cache. Under 2.2.x you are required to specify a interface name when looking up ARP table entries with SIOCGARP. - If the process umask is not set (i.e. 0), then Squid changes it to 007. Changes to Squid-2.3.DEVEL2 (): - Added --enable-truncate configure option. - Updated Czech error messages () - Updated French error messages () - Updated Spanish error messages () - Added xrename() function for better debugging. - Disallow empty ("") password in aclDecodeProxyAuth() (BoB Miorelli). - Fixed ACL SPLAY subdomain detection (again). - Increased default 'request_body_max_size' from 100KB to 1MB in cf.data.pre. - Added 'content_length' member to request_t structure so we don't have to use httpHdrGetInt() so often. - Fixed repeatedly calling memDataInit() for every reconfigure. - Cleaned up the case when fwdDispatch() cannot forward a request. Error messages used to report "[no URL]". - Added a check to return specific error messages for a "store_digest" request when the digest entry doesn't exist and we reach internalStart(). - Changed the interface of storeSwapInStart() to avoid a bug where we closed "sc->swapin_sio" but couldn't set the pointer to NULL. - Changed storeDirClean() so that the rate it gets called depends on the number of objects deleted. - Some WCCP fixes. - Added 'hostname_aliases' option to detect internal requests (cache digests) when a cache has more than one hostname in use. - Async I/O NUMTHREADS now configurable with --enable-async-io=N (Henrik Nordstrom). - Added queue length to async I/O cachemgr stats (Henrik Nordstrom). - Added OPTIONS request method. Changes to Squid-2.3.DEVEL1 (): - Added WCCP support. This adds the 'wccp_router' squid.conf option. - Added internal DNS queries; Most installations can run without the external dnsserver processes. - Rewrote much of the code that stores cache objects on disk. Developed a programming interface that should allow new storage systems to be added easily. This still is pretty ugly and needs a lot of work, however. - Replaced async_io.c "tags" with callback data locks. This probably breaks async IO in a bad way. - Tried to write an Async IO disk storage module. - Added code to replace the StoreEntry linked list with a heap structure. This allows for different replacement algorithms, instead of being stuck with LRU. This adds the 'replacement_policy' squid.conf option. (John Dilley et al). - Fixed HTCP queries by actually checking for freshness based on the HTCP header fields. - Fixed passing of redirector command line arguments. - Added 'request_header_max_size' squid.conf option. - Added 'request_body_max_size' squid.conf option. - Added 'reply_body_max_size' squid.conf option. - Added 'peer_connect_timeout' squid.conf option. - Added 'redirector_bypass' squid.conf option. - Added RFC 2518 (WEBDAV) request methods. Changes to Squid-2.2 (April 19, 1999): - Removed all SNMP specific ACL code SNMP now uses generic squid ACL's - Removed view-based access crontrol - Cleaned up and simplified SNMP section of squid.conf - Changed the SNMP code to use a tree stucture. - Added objects to MIB: Request Hit Ratio's Byte Hit Ratio's Number of Clients - Changed SNMP Agent to return object instances correctly. - Added our own assert() macro so we can use debug() instead of printing to stderr. - Added eventFreeMemory(). - Fixed ipcCreate() bug when debug_log has FD <= 2. - Changed watchChild() and related code in main.c so that Squid can behave more like a proper daemon process. - Added 'prefer_direct' option (enabled by default) so that people can give parents higher preference than direct. - Fixed ipc.c close() bug for async IO. On FreeBSD, comm_close() doesn't work for child processes when async IO is used. - Fixed setting the public key for large ``icons'' (Henrik Nordstrom). - Rewrote peer digest module to fix memory leaks on reconfigure and clean the code. Increased "current" digest version to 5 ("required" version is still 3). Revised "Peer Select" cache manager stats. - Added "-k parse" command line option: parses the config file but does not send a signal unlike other -k options. - Revamped storeAbort() calling. Only store_client.c has all the right information to determine if the request should be aborted. Now client and server modules just storeUnregister without ever needing to call storeAbort. - Small change of Squid output for FTP (Andrew Filonov, Henrik Nordstrom). - clientGetsOldEntry() sends old entry if new request status is in the 500-range (Henrik Nordstrom). - Changed configure so it works with IRIX6.4 C compiler (broken?) option -OPT:fast_io=ON. - Fixed comm_connect_addr() non-blocking connections for SONY NEWSOS (Makoto MATSUSHITA). - Changed "#ifdef __STDC__" to "#if STDC_HEADERS" as recommended by autoconf documentation. - Fixed client-side cache-control max-age (Henrik Nordstrom). - Added a new error page: ERR_SHUTTING_DOWN. fwdStart() returns this error if it is called while squid is in the process of shutting down. - Added support for linuxthreads package under FreeBSD (Tony Finch). - Fixed HP-UX StatHist.c assertions by making the "hbase_f" functions non-static (Michael Pelletier). - Fixed logging of authenticated usernames even if the authorization is not cached (Dancer). - Fixed pconnPush() bug that prevented holding on to persistent connections (Manfred Bathelt). - Pid file now rewritten on SIGHUP. - Numerous Ident changes: - Ident lookups will now be done on demand if you use the 'ident' ACL type. - The 'ident_lookup on|off' option has been replaced with an access list, so you can do lookups only for some client addresses. - Added an 'ident_timeout' option to specifiy the amount of time to wait for an ident lookup. - Added a (local) hit rate to mempool metering. - FTP Restarts (REST command) is now supported. - Check for libintl.a on SCO3.2. - Disable poll() on SCO3.2. - Numerous Async IO enhancements from Henrik. - Removed cache_mem_low and cache_mem_high options (Henrik Nordstrom). - Replaced 'persistent_client_posts' with 'broken_posts' access list. - Rewrote the anonymizer. - Removed the http_anonymizer option. - Added the anonymize_headers option to allow individual referencing of headers for addition or removal. See 'anonymize_headers' in squid.conf for additional configuration. - Fixed config file parser's handing of optional directives. Some people might get new warnings about unknown config directives. - Added 'myip' ACL type. This is the local IP address for connected sockets (Luyer). - Fixed parsing of FTP DOS directory listings with spaces (Nordstrom). - Numerous DELAY_POOL changes/fixes from David Luyer: - Makes no-delay neighbors for DELAY_POOLS work by using a fd_set with the connections to no-delay peers marked in it. - Makes IP addresses ending in 0 and 255, and network number 255, work with individual and network delay pools (they were previously not permitted, and documented as such). - Massive overhaul of delay pools code - dynamically allocated delay pools, as many as required. - delayPoolsUpdate stops running if DELAY_POOLS is configured but no delay pools are configured. - Initial delay pool levels are now configurable as a percentage of the maximum for the pool in question (used to be all set to 1 second worth of traffic). Pools are restored to this level on reconfiguratoin. - Changed storeClientCopy to give a swap-in failure if the number of open disk FD's is above the 'max_open_disk_fds' limit. Otherwise, a very loaded cache will end up with all disk files open for reading, and none for writing. - Added lib/inet_ntoa.c from BSD Unix for systems that have broken inet_ntoa(). (Erik Hofman). - Added more specific FTP error messages for "permission denied, "file not found," and "service unavailable." (Tony Finch) - Added xisspace(), xisdigit(), etc, macros to cast function args and eliminate compiler warnings. - Fixed case-sensitive comparisons of domain names (Henrik Nordstrom). - Added proxy-authentication to cachemgr.cgi's requests (Henrik Nordstrom). - Changed Squid to *truncate* rather than *unlink* purged swap files. Can be reversed by undefining USE_TRUNCATE_NOT_UNLINK in src/defines.h. - Changed internal icon headers to use Cache-control Max-age instead of Expires. - Changed storeMaintainSwapSpace behavior to be adjusted smoothly, instead of discretely, between store_swap_low and store_swap_high. This includes the number of objects to scan, number to remove, and time until the next storeMaintainSwapSpace event. - Fixed a quick_abort bug that incorrectly calculated content lengths. - Added getpwnam() auth module from Erik Hofman. - Added 'coredump_dir' option. - Fixed a peerDestroy() assertion that required peer->digest to be NULL at the end of peerDestroy(). - configure script now automatically enables dlmalloc for Solaris/x86. - configure enables poll() on linux 2.2 and later (Henrik). - Icon files are now distributed in binary format, install will not need to run 'sh' and 'uudecode'. - Fixed some bugs with large responses (>READ_AHEAD_GAP) and re-forwarding requests and ENTRY_FWD_HDR_WAIT. fwdCheckDeferRead() will NOT defer reading if the ENTRY_FWD_HDR_WAIT bit is set. - Fixed a "F->flags.open" assertion for aborted FTP PUT's. - Fixed a (double) cast problem that caused statAvgTick() events to be added as fast as possible. - Changed httpPacked304Reply() to not include the Content-Length header for 304 replies that Squid generates. We used to include the length of the cached object, and this broke persistent connections. 2.2.STABLE2: - Fixed configure bug for statvfs() checks. Configure reports "test: =: unary operator expected" or similar because an unquoted variable is not defined. - Fixed aclDestroyAcls() assertion because some ACL types are not listed in the switch statement. Occurs for srcdom_regex and dstdom_regex ACL types during reconfigure. - Typo "applicatoin" in src/mime.conf - The unlinkd daemon never saw the USE_TRUNCATE_NOT_UNLINK #define because it didn't include squid.h. - Fixed commRetryFD() when bind() fails. commRetryFD was closing the filedescriptor, but it is the upper layer's job to close it. - Changed configure's "maximum number of filedescriptors" detection to only use getrlimit() for Linux. On AIX, getrlimit returns RLIM_INFINITY. - Fixed snmpInit() nesting bug. - Fixed a bug with peerGetSomeParent(). It was adding a parent to the FwdServers list, regardless of the ps->direct value. This could cause every request to go to a parent even when always_direct is used. - Changed fwdServerClosed() to rotate the "forward servers" list when a connection establishment fails. Otherwise it always kept trying to connect to the first server int the list. 2.2.STABLE3: - Fixed preprocessor problems for HP-UX in lib/safe_inet_addr.c. - Avoid coredump in aclMatchAcl() if someone tries to use proxy authentication with a non-HTTP request (e.g. icp_access). - Moved 'ident_lookup_access' in squid.conf so it appears after the ACL section. - Fixed typo in squid.conf on "Config.Addrs.snmp_outgoing" - Fixed a case in clientCacheHit() where we thought it was a hit, but the reply status was not 200, so we had to perform a cache miss. We forgot to change the log_type and these were being recorded as TCP_HIT's. - Fixed a void pointer subtraction bug in delayIdPtrHashCmp(). - Fixed delay_pools coredump and memory leak bugs from NULL delay_id values. - Fixed a SEGV bug with delay_pools when requesting 'objects' or 'vm_objects' from the cachemgr. - Added a workaround for buggy FTP servers that return a size of zero for non-zero-sized objects. - Removed umask(0) call from main(). - Fixed a peer selection bug that caused us to never select a neighbor based on ICP replies if the ICP timeout occurs. In conjunction with this, removed the PING_TIMEOUT state. - Fixed a store_rebuild bug that caused us to get stuck trying if a cache_dir subdirectory didn't exist. - Fixed a buffer overrun bug in gb_to_str(). 2.2.STABLE4: - Fixed a dread_ctrl leak caused in store_client.c - Fixed a memory leak in eventRun(). - Fixed a memory leak of ErrorState structures due to a bug in forward.c. - Fixed detection of subdomain collisions for SPLAY trees. - Fixed logging of hierarchy codes for SSL requests (Henrik Nordstrom). - Added some descriptions to mib.txt. - Fixed a bug with non-hierarchical requests (e.g. POST) and cache digests. We used to look up non-hierarchical requests in peer digests. A false hit may cause Squid to forward a request to a sibling. In combination with 'Cache-control: only-if-cached, this generates 504 Gateway Timeout responses and the request may not be re-forwardable. - Fixed a filedescriptor leak for some aborted requests. Changes to Squid-2.1 (November 16, 1998): - Changed delayPoolsUpdate() to be called as an event. - Replaced comm_select FD scanning loops with global fd_set structures. Inspired by Jeff Mogul's patch for squid 1.1. - Moved functions common to dns.c, redirect.c, authenticate.c, ipcache.c, and fqdncache.c into helper.c. - Changed storeClientCopy2() so that it keeps sending the remainder of a STORE_ABORTED request, instead of cutting off the client as soon as the object becomes aborted. - Fixed combined ipf-transparent proxy and a local http-accelerator operation (Quinton Dolan). - Rewrote base64_decode.c because of potential buffer overrun bugs. - Configurable handling of whitespace in request URI's. See 'uri_whitespace' in squid.conf. - Added ability to generate HTTP redirect messages from the redirector output by prepending "301:" or "302:" to the new url. See FAQ 4.16 for more details. - Eliminated refreshWhen() which was out-of-sync with refreshCheck() potentially causing under-utilized cache digests - Maintain refreshCheck statistics on per-protocol basis so we can tell why ICP or Digests return too many misses, etc. - Fixed delay_pools.c class2/class3 typo (Simon Woods). - Changed squid.conf's default access controls to deny all HTTP requests. Admins must write ACL rules to specifically allow their local clients. - Patched French error messages (Mathias HERBERTS). - NextStep porting fixes by Mike Laster: - use xstrdup() in cf_gen.c - check for putenv() in configure - #define S_ISDIR macro - Added --disable-poll configure option (Henrik Nordstrom). - Fixed internal URL hostname case bugs (Henrik Nordstrom). - Patched ftp.c so we never cache autenticated FTP requests (Henrik Nordstrom). - Fixed FTP authentication. We tried to unescape authentication given by basic authentication which is not URL escaped (Henrik Nordstrom). - Fixed HTTP version for common logfile format (Henrik Nordstrom). - Added 'redirect_rewrites_host_header' option to disable rewriting of Host header for redirector responses (Henrik Nordstrom). - Allow semi-customized error message signatures (Henrik Nordstrom). - Fixed bug with errors for unsupported requests (Henrik Nordstrom). - Fixed handling of blank lines in ACL input files (Henrik Nordstrom). - Changed proxy_auth ACL type to consist of a list of valid users. REQUIRED == any (same as ident ACL). ACL type user changed to ident since this is what it really is. (Henrik Nordstrom). - Fixed long URL bugs; make sure 'log_uri' never exceeds MAX_URL bytes. - Allow comments in external ACL files (Gerhard Wiesinger). - Added 'range_offset_limit' configuration option. Requests with ranges that start after this value will be passed on unmodified, and Squid will not cache the response (Henrik Nordstrom). - Added Client HTTP Hit byte counters to 'counters' output (Douglas Swarin). - Got Squid to compile with --enable-async-io on FreeBSD. - Fixed infinite loop bug for cachemgr 'config' option. - Fixed cachability bugs for replies with Pragma: no-cache. - Made content-type multipart/x-mixed-replace uncachable. - Y2K fix for parsing dates in "Wed Jun 9 01:29:59 1993 GMT" format (Richard Kettlewell). - Fixed passing -s option to dnsserver processes (Alvaro Jose Fernandez Lago). - Changed proxy_auth to work on internal objects and when in accelerator mode. (Henrik Nordstrom) - Added login=user:password option to cache_peer directive to be used from a dial-up cache where the parent requires proxy authentication. (Henrik Nordstrom) - If you want to "auto-login", then use a URL on the form http://username:password@server/.... Squid now picks this up when going direct, and turns it into basic WWW authentication. It is also possible to do automatic login to certain servers by using a redirector to add the needed authentication information. (Henrik Nordstrom) - Changed refreshCheck() so that objects with negative age are always stale. - Fixed "plain" FTP listings (Henrik Nordstrom). - Fixed showing banner/logon message for top-level FTP directories (Henrik Nordstrom). * Changes below have been made to SQUID_2_1_PATCH1 - Fixed pinger packet size assertion. - Fixed WAIS forwarding. - Fixed dnsserver coredump bug caused by using both -D and -s options. * Changes below have been made to SQUID_2_1_PATCH2 - Fixed EBIT macro bugs when the bitmask is a 64-bit long. - Fixed proxy auth NULL password bug. - Fixed queueing of multiple peerRefreshDNS events. - Added a stack of StoreEntry objects to be released after store rebuild completes. - Fixed NULL pointer bugs with too-large requests (found by Martin Lathoud). - Fixed reading replies from buggy ident servers. Replies might not have terminating CR or LF (Henrik Nordstrom). - Changed internal StoreEntry key so that the request method is encoded as a single octet. Encoding an enumerated type has size and byte-order incompatibilities, especially for cache digests. - Fixed storeEntryLocked so that SPECIAL, but PRIVATE entries are not always locked. This fixes having multiple store_digest's stuck in memory. - Fixed clientProcessOnlyIfCachedMiss so it unlocks and unregisters from "cache hit" entries. * Changes below have been made to SQUID_2_1_PATCH3 - Fixed memory leak in clientHandleIMSReply for storeClientCopy failures. Changes to Squid-2.0 (October 2, 1998): - Added NAT/Transparent hijacking code from Quinton Dolan. - Added actual filesystem usage to cachemgr 'storedir' page. Only works for operating systems which support statvfs(). - Fixed HTCP compile-time bugs. - Fixed quick_abort bugs. Configured values are stored as Kbytes, not bytes. - Removed fwdAbortFetch(). It breaks quick_abort and seems mostly useless. - Changed storeDirSelectSwapDir() to skip swap directories when their utilization is over the high water mark ratio. - Fixed off-by-one bug for dead neighbor detection (Joe Ramey). - fixed bugs in Content-Range header generation - changed the way Range requests are handled: - do not "advertise" our ability to process ranges at all - on hits, handle simple ranges and forward complex ones - on misses, fetch the whole document for simple ranges and forward range request for complex ranges The change is supposed to decrease the number of cases when clients such as Adobe acrobat reader get confused when we send a "200" response instead of "206" (because we cannot handle complex ranges, even for hits) Note: Support for complex ranges requires storage of partial objects. - Removed SNMP mib-2.system group from squid. - Removed SNMP ability to iterate through ipcache and friends. - Added SNMP ipcache/fqdncache basic statistics. - Converted SQUID-MIB to SMIv2 (RFC 1902). - Moved SQUID-MIB to enterprises section of the tree in preparation of the split into PROXY-MIB & SQUID-MIB. - Corrected minor errors in SQUID-MIB. - Moved uptime into cacheSystem from cacheConfig. - Corrected a number of get-next-request bugs, snmpwalk should now return all objects and not skip some. - Fixed netdbClosestParent() so it won't return sibling peers. - Fixed a bug with secondary clients on entries with ENTRY_BAD_LENGTH set. We should release the bad entry to prevent secondary clients jumping on. - Changed MIB to prevent parse warnings at startup. * Changes below have been made to SQUID_2_0_PATCH1 - Fixed a forwarding loop bug. Even though we were detecting a loop, it was not being broken. - Try to prevent sibling forwarding loops by NOT forwarding a request to a sibling if we have a stale copy of the object. Validation requests should only be sent to parents (or direct). - Fixed ncsa_auth hash bugs when re-reading password file. - Changed clientHierarchical() so that by default SSL/CONNECT requests do NOT go to neighbor caches. - Changed clientHandleIMSReply() to not call storeAbort() because there can be more than one client hanging on the StoreEntry. This hopefully fixes "store_status != STORE_ABORTED" assertions. - Added temporary fix to httpMakePublic() to prevent assertions (!EBIT_TEST(e->flags, RELEASE_REQUEST)) in storeSetPublicKey(). * Changes below have been made to SQUID_2_0_PATCH2 - PATCH1 introduced a seriously stupid bug which prevented ICP queries for all requests. Fixed by checking request->hierarchical in peerSelectFoo(). Changes to squid-1.2.beta25 (September 21, 1998): - Fixed async IO bugs from adding filedescriptor arg to AIOCB callbacks (Henrik Nordstrom). - Fixed store_swapout.c assertion. We were freeing object data past the swapout_done offset. This probably happens (only?) when an object changes from cachable to uncachable while it is being swapped out. - Added MEM_CLIENT_SOCK_BUF type so we can change the size of the buffers used for writing data to the client sockets. - Added configure check for libbind.a. If found, it will be used instead of libresolv.a. - Changed fwdStart() to always allow internally generated requests, such as for peer digests. These requests are known to fwdStart() because the address arg is set to 'no_addr'. - Completed initial HTCP implementation. It works, but is not tested much. - Added counters for I/O syscalls. - Fixed httpMaybeRemovePublic. With broken ICP neighbors (netapp) Squid doesn't use private keys. This caused us to remove almost every object from the cache. - Added 'asndb' cachemgr stats to show AS Number tree. - Fixed AS Number byte-order bug for netmasks. - Fixed comm_incoming calling rate for high loads (Stewart Forster). - Give always_direct higher precedence than never_direct (Henrik Nordstrom). - Changed PORT ACL type to accept ranges. Now you can easily deny, for example, all priveleged ports except 80, 70, 21, etc. - ARP ACL fixes for Linux (David Luyer). - Replaced various "EBIT" flags bitfileds with structures of "int:1" members. - Changed storeKeyPrivate and storeKeyPublic to be a bit more efficient by removing snprintf(). This causes an incompatibility with old cache keys, however. To transition, we will look up both the new and old style keys for about the next 30 days. After that, if you haven't run this (or a future) version, your cache contents will be lost. - Made the client-side write buffer size configurable with a #define in defines.h. By default it is still 4096 bytes. - Removed redirectUnregister(). It should be unnecessary because of cbdata locks. - Fixed multiple HEAD request brokennesses (Henrik Nordstrom). - Changed non-blocking connect(2) code to call getsockopt() instead of connect() again. This is the approach recommended by Stevens, and fixes bugs on BSD-ish systems when subsequent connect() calls loop with EAGAIN status. - Added MD5 cache keys to memory pool accounting. - Added code to track number of open DISK descriptors and stop swapping out objects if the number of disk descriptors becomes too large. For now the limit must be manually configured with the 'max_open_disk_fds'. By default, there is no limit. - Stopped encoding a request method in the high byte of the ICP reqnum field. Instead queried cache keys are copied to a static array, indexed by the reqnum, modulo the array size. Now we just use the request number to lookup a cache key, instead of rebuilding it from the ICP reply URL and method, unless we have netapp neighbors--they don't do reqnum properly. - Fixed reconfigure memory access bugs in redirect.c. - Ignore unreasonably large ICP RTT values which cause overflow bugs in calculating the average RTT (thanks Niall!) Changes to squid-1.2.beta24 (August 21, 1998): - Added Bulgarian error pages by Evgeny Gechev. - Changed StoreEntry->lock_count to a u_short. - Replaced urlcmp with strcmp - Fixed pragma no-cache ejecting ENTRY_SPECIAL objects (Henrik Nordstrom). - Eliminated unneeded BASE HREF on "root" directories (Henrik Nordstrom). - Fixed peerDigestFetchFinish() assertion caused by forwarding failures (e.g. miss_access rules). - Changed signal handlers with ASYNC_IO and Linux so that -k command line options work (Miquel van Smoorenburg). - Rewrote shutdown code to use events instead of setting FD timeouts. - Fixed cachemgr 'objects' (statObjects()) by adding a check for READ_AHEAD_GAP, and calling storeCheckSwapout() in storeBufferFlush(). Otherwise, the read-past pages would never be freed. - Fixed DNSSERVER shutdown bugs. The re-opened dnsserver processes were being closed by the dnsServerShutdown event. - Modified storeHashInsert() to insert PRIVATE objects at the tail of the LRU list, and PUBLIC objects at the head. Thus, PRIVATE objects get kicked out quicker. - Added David Luyer's DELAY_POOLS code. - Fixed a bug due to HEAD replies which lack the end-of-headers line. - Made proxy-auth realm string configurable (Bob Franklin) - Changed default mime time to a viewable one (Henrik Nordstrom). - configure fixes for Sony's NEWS-OS 6.x (Makoto MATSUSHITA). - Fixed 'you are running out of filedescriptors' bug which could cause the HTTP incoming connection handler to not be reset. - Changed syslog logging. Now squid debug levels 0 and 1 go to syslog. Level 0 gets LOG_WARNING and level 1 gets LOG_NOTICE (this needs more work!) - Fixed memory access errors in statAvgTick(). - Fixed duplicate requestUnlink() bug in forward.c - Fixed possible memory access bugs from not setting e->mem_obj = NULL in destroy_MemObject(). - Deleted TCP_IMS_MISS tag. Always use TCP_IMS_HIT instead. - Modified headersEnd and httpMsgIsolateHeaders to account for funky line terminations such as CRCRNL. (``but Netscape and IE _tolerate_ this'') - Fixed carp functions (Eric Stern). - Replaced internal proxy_auth code with extern authentication module (Arjan de Vet). - moved hash.c to libmiscutil.a. - Fixed handling of ICP queries with whitespace in URLs. Now we return ICP error and escape the URL before logging. - Added configure check for socklen_t (David Luyer). - Removed USE_SPLAY #defines; it is now standard. - Added FD arg to async IO callbacks (AIOCB) so we can eliminate temporary disk_ctrl_t structures. - Changed ENOSPC disk write errors to reduce specific cache_dir sizes, and not just the size of the cache as a whole. - Added httpMaybeRemovePublic() to purge public objects for certain responses even though they are uncachable. This is needed, for example, when an initially cachable object later becomes uncachable. - Added refresh_pattern options to ignore client reloads (Henrik Nordstrom) - Relocated disk.c code which combines blocks for writing (Stewart Forster). Changes to squid-1.2.beta23 (June 22, 1998): - Added Turkish error pages by Tural KAPTAN. - Added basic support for Range requests. For most cachable requests, Squid replies with an "Accept-Ranges" header. Upon receiving a potentially cachable Range request for a not cached object, Squid requests the whole object from origin server and then replies with specified range(s) to the client. Multi-range requests are supported. Adjacent overlapping ranges are merged. If-Range requests are supported. Limitations: Multi-range requests with out of order ranges are not supported. - Made md5.c use standard memcpy and memset if they are avaliable. - Memory pools will now shrink if Squid is run-time reconfigured with smaller value of memory_pools_limit tag. - Added counter for number of clients (Tomi Hakala). - Changed neighbor UP/DOWN algorithm to require 10 failed TCP connections for UP->DOWN transition. - Added 'unique_hostname' configuration option when its necessary to have multiple machines with the same visible hostname. - Fixed pumpReadFromClient() to not read too many bytes on persistent connections. - We can now cache HTTP replies with Set-Cookie. These evil headers are now filtered out for cache hits on the client side. - Fixed SNMP bugs caused by using snmpwalk. - Fixed snmp system Group; all objects are now returned. - Fixed snmp system Group sysDescr and sysContact. - Fixed snmp system Group sysObjectID it now returns a OBJECT IDENTIFIER. - Allocate FwdState from mem pools. - Minor HTCP progress. - Moved 'miss_access' ACL check from client_side.c to forward.c - Fixed logging of usernames for requests which require proxy-authentication. - Fixed HTTP request parser to accept lowercase HTTP identifier (Oskar Pearson). - Fixed FTP listings to always include links to the parent directory (Henrik Nordstrom). - Fixed FTP to show an "empty" listing instead of showing a "document contains no data" error (Henrik Nordstrom). - Fixed refreshCheck() bug. Often it was checking the refresh patterns against the string "[null_mem_obj]" because we moved URLs to MemObject. - Added CARP support by Eric Stern. - Fixed select-spin bug when an ICP reply actually gets queued and we failed to execute the write callback. - Fixed a storeCheckSwapOut bug. We were freeing up to the queued offset instead of the done offset. This resulted in a small chunk of object data not being in memory and not yet written to disk. A client could recieve a partial object because file_read() unexpectedly returns EOF. - Fixed proxy-authentication hangs (Henrik Nordstrom). - Fixed request_t->flags bug causing authenticated, proxied responses to be cached (Arjan de Vet). - Fixed MIME types for .tgz extension (Henrik Nordstrom). - Added view and download options to FTP listings (Henrik Nordstrom). - Modified configure to allow using pre-installed libdlmalloc.a (Masashi Fujita). - Fixed cachemgr 'objects' implementation. - Changed refreshCheck() algorithm. For cached objects, we now check, in the following order: * request max-age * response Expires (if present) * refresh_pattern max-age * response Last-Modified compared to refresh_pattern LM-factor (only if Last-Modified is present) * refresh_pattern min-age - Changed Copyrights. Changes to squid-1.2.beta22 (June 1, 1998): - do not cut off "; parameter" from "digitized" Content-Type http fields - Added X-Request-URI for persistent connection debugging (Henrik Nordstrom) - Added Polish error pages from Maciej Kozinski. - Fixed hash_first/hash_next bugs with **Current pointer. Replaced with *next pointer. - Fixed PUT/POST bugs in client (Henrik Nordstrom). - Deny forwarding loops in httpd accel mode (Henrik Nordstrom). - Fixed eventRun "spin" bug when event delta time == 0. - Fixed setting Last Modified time on cached entries when receiving a 304 reply. - Added while loop in httpAccept(). - Added while loop in icpHandleUdp(). - Fixed some small memory leaks. - Fixed single-bit-int flag checks (Henrik Nordstrom). - Replaced "complex" (offset accounting) calls to snprintf with MemBuf - Do not send only-if-cached cc directive with requests for peer's digests. - Added "automatic tuning" for incoming request rate, i.e. how often to check HTTP and ICP sockets. See comm.c comments for details. Changes to squid-1.2.beta21 (May 22, 1998): - Added Italian error pages by Alessio Bragadini. - Added Estonian error pages by Toomas Soome. - Added Russian (koi-r) error pages by Andrew L. Davydov. - Added Czech error pages by Jakub Nantl. - Fixed asnAclInitialize calling to prevent coredump. - Fixed FTP directory parsing again. - Made FTP directory listing "Generated" tagline like the one for error pages. - Fixed an assertion coredump in statHistCopy from reconfiguring with different #peers in squid.conf - Ignore leading whitespace on requests (and replies). RFC 2068 section 4.1, robustness (Henrik Nordstrom) - Fixed keep_alive bug. We did not always honour reply headers, but rather assumed connections could be persistent. - Fixed reading whois output for AS numbers, especially when they are longer than 4 KB. - Removed 'cache_stoplist_pattern' configuration option. This feature is now handled by 'no_cache'. - If a URN resolves to only one URL, just return it immediately instead of giving the user a "choice" (Andy Powell). - Fixed year-2000 bug in lib/iso3307.c (Henrik Nordstrom). - Changed squid-internal object names. - Added netdb exchange protocol. - Fixed wordlistDestroy() uninitialized pointer bug in ftpParseControlReply. - Fixed redirector subprocess to show real program name. - Changed URN menu output to be sorted. - Added fast select(2) timeouts when using ASYNC_IO. - Added ARP ACL support for Linux (David Luyer). - Added binary http headers to requests - request_t objects are now created and destroyed in a consistent way - Fixed cache control printf bug - Added a lot of new http header ids - Improved Connection: header handling; now both Connection and Proxy-Connection headers are checked for connection directives - Connection request header is now handled correctly regardless of its position and the number of entries - Only replies with valid Content-Length can be sent with keep-alive connection directive (Henrik Nordstrom) - Better handling of persistent connection "clues" in HTTP headers; the decision now depends on HTTP version (and User-Agent exceptions) - Removed handling of "length=" directive in IMS headers; the directive is not in the HTTP/1.1 standard; standing by for objections - allowed/denied headers are now checked using bit masks instead of strcmp loops - removed Uri: from allowed headers; Uri is deprecated in RFC 2068 - removed processing of Request-Range header (not in specs?) - Fixed byte-order bugs in cacheDigestHashKey. - Changed hash_remove_link() to return void. - Changed ipcache_gethostbyname() to return NULL if i->addrs.count == 0. - Added millisecond-timing to select/poll loops and event queue. - Changed 'peerPingTimeout' value to be twice the average of all the peer ICP RTT's. - Added 'half_closed_clients' option to force closing of client connections which might only be half-closed. - Fixed matchDomainName coredump bug. - Don't cache HTTP replies with Vary: headers until we get content negotiation working. - Fixed SSL proxying to forward full HTTP request headers. - Changed storeGetMemSpace(). Only purge down to the HIGH water mark; move locked entries to the head of the inmem list. - Changed clientReadRequest() to locally handle any "squid-internal-static" URL for any host. - Disable persistent connections for client connections from broken Netscape User-Agent, version 3.* (Stewart Forster) Changes to squid-1.2.beta20 (April 24, 1998): - Improved support for only-if-cached cache control directive. - Enabled 304 replies for ENTRY_SPECIAL objects (e.g., icons). - Fixed 'quick_abort' percent calculation bug. - Fixed quick_abort FPE bug. - Changed more errno-checking functions to use ignoreErrno(). - Added ERESTART to ignoreErrno() because of report from a Solaris system. - Fixed '#elsif' typo. - Fixed MemPool assertion by moving memInit() to before configuration parsing functions. - Fixed default 'announce_period' value (was 1 day, should be 0) (Joe Ramey). - Added configure warning for low filedescriptors and pointer to FAQ. - Fixed httpBodySet() bug causing URN related coredumps. - Changed ipcacheCycleAddr() to always cycle through all all available addresses, and not just advance when one of them goes BAD. - Fixed squid-internal bug for mixed-case hostnames (Henrik Nordstrom). - Fixed ICP counting probelm. icpUdpSend() arg should be LOG_ICP_QUERY instead of LOG_TAG_NONE. - Added some additional fault toleranse on FTP data channels (Henrik Nordstrom). - Corrected error reporting on FTP "hacks" (Henrik Nordstrom). - Added lock/unlock for StoreEntry during storeAbort(). - Added filemap bit usage stats to cachemgr 'storedir' and 'info'. - Replaced 'cache_stoplist' with 'no_cache' Access list. - Fixed (hopefully) remaining swapfile-open-at-exit bugs. - Fixed default hierarchy_stoplist to be ``default if none.'' - Fixed 'fake a recent reply' hack for detecting DEAD and ALIVE neighbors (Joe Ramey). - Fixed FTP directory parsing bugs (Joe Ramey). - Fixed ftpTraverseDirectory coredump for NULL ftpState->filepath (Joe Ramey). - Fixed daylight savings time bug (again). - A lot of Cache Digests additions, fixes, and tuning. Cache Digests are still "very experimental". - Fixed snprintf() bug. When len == 1, snprintf() would treat the buffer as unknown size, emulating sprintf() behaviour. - Made Error page language configurable with configure script (Henrik Nordstrom). - Fixed squid-internal URLs when http_port == 80. - Remember the client address on redirected requests (Henrik Nordstrom). - Don't rebuild the request if the redirector returned the same URL (Henrik Nordstrom). - Rewrite Host: header on redirected requests (Henrik Nordstrom). - Include port (if non-standard) in generated Host: headers (Henrik Nordstrom). - Fixed rfc1123 timezone hacks for Windows NT (Henrik Nordstrom). - Added Russian Error pages by Ilia Zadorozhko. - Added totals for ICP and HTTP hits to cachemgr client_list output. - Changed error message to 'Generated TIME by HOST (SQUID/VER)' because any string with an '@' must be an email address. - Fixed POST for content-length == 0. - Fixed "huge 304 reply" loop bug. - Fixed --enable-splaytree compile bugs. - Removed ASN lookup code in peer_select.c. - Added warnings if ACL code detects subdomains in SPLAY trees. - Rewrote some bits of httpRequestFree() to eliminate possible bugs that could cause an "e->lock_count" asseertion. - Added value/bounds checking to _db_init() when setting the debugLevels[] array. Changes to squid-1.2.beta19 (Apr 8, 1998): - Squid-1.2.beta19 compiles and runs on Windows/NT with Cygnus Gnu-WIN32 b19 (Henrik Nordstrom). - Added French Error pages by Frank DENIS. - Added Dutch Error pages by Mark Visser - Added German Error pages by Bernd P. Ziller, Jens Frank, and Anke S. - Added support for only-if-cached cache-control directive. - Added RELAXED_HTTP_PARSER #define to allow requests which are missing the HTTP identifier on the request line (e.g. buggy SpyGame queries). RELAXED_HTTP_PARSER is undefined by default. - Fixed disk.c FD leak for delayed closes in diskHandleWriteComplete(). - Fixed cache announcement feature. - Fixed httpReadReply() to retry failed HTTP requests on persistent connections when read() returns -1, not only when it returns 0. - Fixed cbdata memory counting leak. cbdataUnlock() always called free(), never memFree(). - Fixed storeDirWriteCleanLogs() malloc bug on Alphas. - Fixed `++loopdetect < 10' assertion due to clientHandleIMSReply bug for invalid/partial HTTP replies. - Added preliminary code for HTCP. - Renamed 'aux' dir to 'cfgaux' for legacy DOS machines. - Added "snmp_community" as an ACL type. - Cleaned up proxy-auth acl implementation and removed memory leaks. - Added generic 'hashFreeItems()' function for efficiently freeing hash table pointers. - Added whoisTimeout() for ASN code. - Removed BINARY TREE code. - Fixed forgetting to reset Config.Swap.maxSize in configDoConfigure. - Fixed httpReplyUpdateOnNotModified() arguments-in-wrong-order bug which caused not modified replies to not get updated. - Fixed client_side.c bugs which could cause data to be written to the client in the wrong order for persistent connections. clientPurgeRequest() and clientHandleIMSComplete() must not call comm_write(). Instead they must create and write to StoreEntry's. - Fixed ICP query service time counting bug(s). - replaced 'char *mime_headers_end()' with 'size_t headersEnd()' to fix buffer overruns. This also requires adding 'buf_sz' args to some functions like clientBuildReplyHeader(). But we can eliminate the need to NULL-terminate the buffer beforehand. - Changed commConnectCallback() to reset the FD timeout to zero before notifying about the connection. This requires commSetTimeout() calls in numerous places to reinstall timeouts. - Changed comm_poll_incoming() to be called less frequently (every 15 I/O's instead of every 7 FD's) (Michael O'Reilly). - Removed HAVE_SYSLOG case for debug() macro. Almost all systems do have syslog(), but more importatnly the _db_level value is needed for debugging to stderr. - Rewrote squid/dnsserver interface to use smaller, single-line messages. - Rewrote 'dns' cachemgr output to use a table format. - Rewrote a lot of dnsserver.c. - Added eventAddIsh() for semi-random event scheduling. - Fixed an ftpTimeout bug for sessions which use PORT commands. - Fixed ftp.c to recognized invalid PASV replies (e.g. port == 0). - Removed hash_insert(). All hasing uses hash_join() now. - Renamed hash_unlink() to hash_remove_link(). - Added hashPrime() to find closes prime hash table size to a given value. - Fixed Keep-Alive ratio counting bug which prevented persistent connections from being used between cache peers. - Changed icmp.c to NOT queue messages sent from squid to the pinger program. - Changed icp_v2.c to NOT queue ICP messages by default. But they will be queued and resent once if the first send fails. Counters.icp.queued_replies counts the number of messaages queued. - Cleaned up ICP logging. - Added identTimeout(). - Fixed ipcache reply counting bug. Overcounted dnsserver replies for partial replies. - Added urlInternal() for building internal Squid URLs. - Changed peerAllowedToUse() to check both 'cache_peer_domain' AND 'cache_peer_acl' configurations. This should be changed in the fugure to use ONLY cache_peer_acl. - Changed DEAD/REVIVED neighbor detection to avoid reporting so many false deaths. (Joe Ramey). - Added some preliminary code to support "cache digests." - Fixed pumpClose() coredumps (?). - Updated cachemgr 'info' output to show median service times for various categories. - Fixed ABW bug in storeDirWriteCleanLogs(). sizeof(off_t) != sizeof(int) for Alphas. - Fixed potential alignment problem in storeDirWriteCleanLogs(). - Fixed store_rebuild.c to NOT replace current, but not-swapped-out StoreEntry's with on-disk entries. - Changed storeCleanup() to call storeRelease on invalid entries which don't have a swapfile (i.e. no unlink() penalty). - Fixed storeSwapInStart() to fail for unvalidated entries. - SNMP changes: . renovated mib and added descriptions and comments . added hit and byte counters to client_db , for cacheClientTable . cacheClientTable, netdbTable, cachePeerTable, cacheConnTable now indexed by ip address. hash_lookup was enhanced to allow for subsequent hash_next's similar to hash_first, to speed up getnext's in tables which refer to hash-table structures. . added generic (well, sorf of) table indexing functionality . added makefile dependencies for snmplib and cache_snmp.h . WaisHost, WaisPort, Timeouts removed . FdTable split into FdTable and ConnTable. FdTable simplified . PeerTable and PeerStat merged and put into new cacheMesh group . cacheClientTable added for client statistics and accounting (cacheMesh 2) . cacheSec and cacheAccounting groups removed . fixed acl bug when communities not defined . snmp_acl now survives bad configuration Changes to squid-1.2.beta18 (Mar 23, 1998): - Added v1.1 'test_reachability' option. - Fixed hash4() len == 0 bug. - Fixed Config.Swap.maxSize reconfigure bug. - Fixed ICP query bug determining request method. - Moved ICP's storeGet() cache lookup into neighborsUdpAck() so that we know neighbors are alive even when they send us replies for unknown entries. - Changed configure script to add '-std1' for Digital Unix cc. - Fixed SNMP sizeof(int) / sizeof(long) bugs for 64-bit systems. - Added support for 'Cache-Control: Only-If-Cached' request header. - Fixed CheckQuickAbort() bugs for multiple clients on one StoreEntry. Also changed storePendingNClients() to return mem->nclients instead of counting the number of store_client entries with pending callback functions. Changes to squid-1.2.beta17 (Mar 17, 1998): - SNMP MIB version check changed to non-rcs. - Added memory pools for variable size objects (strings). There are three pools; for small, medium, and large objects. - Extended String object to use memory pools. Most fixed size char array fields will be replaced using string pools. Same for most malloc()-ed buffers. - Changed icon handling to use the hostname and port of the squid server, instead of the special hostname "internal.squid" (Henrik Nordstrom). - All icons are now configured in mime.conf. No hardcoded icons, including gohper icons (Henrik Nordstrom). - Fixed ICP bug when we send queries, but expect zero replies. - Fixed alignment/casting bugs for ICP messages. - A generic client-to-server "pump" was added to handle HTTP PUT as well as POST methods on the client-cache side. Based on "pump" PUT requests can be made to either HTTP or FTP url's. Code is still beta and interoperability with browsers etc has not been tested. - Put #ifdefs around 'source_ping' code. - Added missing typedef for _arp_ip_data (Wesha). - Added regular-expression-based ACLs for client and server domain names (Henrik Nordstrom). - Fixed ident-related coredumps from incorrect callback data. - Fixed parse_rfc1123() "space" bug. - Fixed xrealloc() XMALLOC_DEBUG bug (not calling check_free()).. - Fixed some src/asn.c end-of-reply bugs and memory leaks. - Fixed some peer->options flag-setting bugs. - Fixed single-parent feature to work again - Removed 'single_parent_bypass' configuration option; instead just use 'no-query'. - Surrounded 'source_ping' code with #ifdefs. - Changed 'deny_info URL' to use a custom Error page. - Modified src/client.c for testing POST requests. - Fixed hash4() for SCO (Vlado Potisk). Changes to squid-1.2.beta16 (Mar 4, 1998): - Added Spanish error messages from Javier Puche. - Added Portuguese error messages from Pedro Lineu Orso - Added a simple but very effective hack to cachemgr.cgi that tries to interpret lines with '\t' as table records and formats them accordingly. With a few exceptions (see source code), first line becomes a table heading ("" html tag) and the rest is formated with "" tags. - Added "mem_pools_limit" configuration option. Semantics of "mem_pools" option has also changed a bit to reflect new memory management policy. - Reorganized memory pools. Squid now supports a global pool limit instead of individual pool limits. Per-pool limits can be implemented on top of the current scheme if needed, but it is probably hard to guess their values. Squid distributes pool memory among "frequently allocated" objects. There is a configurable limit on the total amount of "idle" memory to be kept in reserve. All requests that exceed that amount are satisfied using malloc library. Support for variable size objects (mostly strings) will be enabled soon. - memAllocate() has now only one parameter. Objects are always reset with 0s. (We actually never used that parameter before; it was always set to "clear"). - Added Squid "signature" to all ERR_ pages. The signature is hardcoded and is added on-the-fly. The signature may use %-escapes. Added interface to add more hard-coded responses if needed (see errorpage.c::error_hard_text). - Both default and configured directories are searched for ERR_ pages now. Configured directory is, of course, searched first. This allows you to customize a subset of ERR_ pages (in a separate directory) without danger of getting other copies out of sync. - Security controls for the SNMP agent added. Besides communities (like password) and views (part of tree accessible), the snmp_acl config option can be used to do acl based access checks per community. - SNMP agent was heavily re-written, based on cmu-snmpV1.8. You can now walk through the whole mib tree. Several new variables added under cacheProtoAggregateStats - Added rudimental statistics for HTTP headers. - Adjusted StatLogHist to a more generic/flexible StatHist. Moved StatHist implementation into a separate file. - Added FTP support for PORT if PASV fails, also try the default FTP data port (Henrik Nordstrom). - Fixed NULL pointer bug in clientGetHeadersForIMS when a request is cancelled for fails on the client side. - Filled in some squid.conf comments (never_direct, always_direct). - Added RES_DNSRCH to dnsserver's _res.options when the -D command line option is given. - Fixed repeated Detected DEAD/REVIVED Sibling messages when peer->tcp_up == 0 (Michael O'Reilly). - Fixed storeGetNextFile's incorrect "directory does not exist" errors (Michael O'Reilly). - Fixed aiops.c race condition (Michael O'Reilly, Stewart Forster). - Added 'dns_nameservers' config option to specify non-default DNS nameserver addresses (Maxim Krasnyansky). - Added lib/util.c code to show memory map as a tree (Henrik Nordstrom). - Added HTTP and ICP median service times to Counters and cachemgr average stats. - Changed "-d" command line option to take debugging level as argument. Debugging equal-to or less-than the argument will be written to stderr. - Removed unused urlClean() function from url.c. - Fixed a bug that allowed '?' parts of urls to be recorded in store.log. Logged urls are now "clean". - Cache Manager got new Web interface (cachemgr.cgi). New .cgi script forwards basic authentication from browser to squid. Authentication info is encoded within all dynamically generated pages so you do not have to type your password often. Authentication records expire after 3 hours (default) since last use. Cachemgr.cgi now recognizes "action protection" types described below. - Added better recognition of available protection for actions in Cache Manager. Actions are classified as "public" (no password needed), "protected" (must specify a valid password), "disabled" (those with a "disable" password in squid.conf), and "hidden" (actions that require a password, but do not have corresponding cachemgr_passwd entry). If you manage to request a hidden, disabled, or unknown action, squid replies with "Invalid URL" message. If a password is needed, and you failed to provide one, squid replies with "Access Denied" message and asks you to authenticate yourself. - Added "basic" authentication scheme for the Cache Manager. When a password protected function is accessed, Squid sends an HTTP_UNAUTHORIZED reply allowing the client to authorize itself by specifying "name" and "password" for the specified action. The user name is currently used for logging purposes only. The password must be an appropriate "cachemgr_passwd" entry from squid.conf. The old interface (appending @password to the url) is still supported but discouraged. Note: it is not possible to pass authentication information between squid and browser *via a web server*. The server will strip all authentication headers coming from the browser. A similar problem exists for Proxy-Authentication scheme. - Added ERR_CACHE_MGR_ACCESS_DENIED page to notify of authentication failures when accessing Cache Manager. - Added "-v" (Verbose) and "-H" (extra Headers) options to client.c. - Added simple context-based debugging to debug.c. Currently, the context is defined as a constant string. Context reporting is triggered by debug() calls. Context debugging routines print minimal amount of information sufficient to describe current context. The interface will be enhanced in the future. - Replaced _http_reply with HttpReply. HttpReply is a stand-alone object that is responsible for parsing, swapping, and comm_writing of HTTP replies. Moved these functions from various modules into HttpReply module. - Added HttpStatusLine, HttpHeader, HttpBody. - All HTTP headers are now parsed and stored in a "compiled" form in the HttpHeader object. This allows for a great flexibility in header processing and builds basis for support of yet unsupported HTTP headers. - Added Packer, a memory/store redirector with a printf interface. Packer allows to comm_write() or swap() an object using a single routine. - Added MemBuf, a auto-growing memory buffer with printf capabilities. MemBuf replaces most of old local buffers for compiling text messages. - Added MemPool that maintains a pre-allocated pool of opaque objects. Used to eliminate memory thrashing when allocating small objects (e.g. field-names and field-value in http headers). Changes to squid-1.2.beta15 (Feb 13, 1998): NOTE: This version has changes which may cause all or part of your cache to be lost. However, you can problably save most of it by doing a slow restart. Specifically: 1. Kill the running squid-1.2.beta14 process; wait for it to fully exit. 2. Remove all 'swap.state*' files, either in each cache_dir, or as defined in your squid.conf 3. Start squid-1.2.beta15. The store will be rebuilt from the existing swap files, reading the directories and opening the files. - Fixed some problems related to disk (and pipe) write error handling. file_close() doesn't always close the file immediately; i.e. when there are pending buffers to write. StoreEntry->lock_count could become zero while a write is pending, then bad things happen during the callback. - The file_write() callback data must now be in the callback database (cbdata). We now use the swapout_ctrl_t structure for the callback data; it stays around for as long as we are swapping out. - Changed the way write errors are handled by diskHandleWrite. If there is no callback function, now we exit with a fatal message under the assumption that the file in question is a log file or IPC pipe. Otherwise, we flush all the pending write buffers (so we don't see multiple repeated write errors from the same descriptor) and let the upper layer decide how to handle the failure. - Fixed storeDirWriteCleanLogs. A write failure was leaving some empty swap.state files, even though it tells us that its "not replacing the file." Don't flush/rename logs which we have prematurely closed due to write failures, indiciated by fd[dirn] == -1. Close these files LAST, not before renaming. - Fixed storeDirClean to clean directories in a more sensible order, instead of the new "MONOTONIC" order for swap files. - Merged fdstat.c functions into fd.c. - Cleaned up some debugging sections. Some unrelated source files were using the same section. - Removed curly brackets from all cachemgr output. - Removed unused filemap->last_file_number_allocated member. - Removed unused fde->lifetime_data member. - Fixed incorrectly applying htonl() on icp_common_t->shostid. - Call setsid() before exec() in ipc.c so that child processes don't receive SIGINT (etc) when running squid on a tty. - Changed StoreEntry->object_len to ->swap_file_sz so we can verify the disk file size at restart. Moved object_len to MemObject->object_sz. Note object_sz is initialized to -1. If object_sz < 0, then we need to open the swap file and read the swap metadata. - Changed store_client->mem to ->entry because we need e->swap_file_sz to set mem->object_sz at swapin. - Renamed storeSwapData structure to storeSwapLogData. - Fixed storeGetNextFile to not increment d->dirn. Added check for opendir() failure. - Fixed storeRebuildStart to properly link the directory list for storeRebuildfromDirectory mode. - Added -S command line option to double-check store consistency with disk files in storeCleanup(). - Fixed a problem with transactional logging. In many cases we were adding the public cache key and then logging a delete for the private key. This is worthless because during rebuild we could not locate the previous public-keyed entry. Now we assert that only public-keyed entries can be logged to swap.state. storeSetPublicKey() and storeSetPrivateKey() have been modified to log an ADD or DEL when the key changes. - Fixed storeDirClean bug. Needed to call storeDirProperFileno() so the "dirn bits" get set. - Fixed a storeRebuildFromDirectory bug. fullpath[] and fullfilename[] were static to that function and did not change when the "rebuild_dir" arg did. Moved these buffers to the rebuild_dir structure. - In storeRebuildFromSwapLog, we were calling storeRelease() for cache key collisions. This only set the RELEASE_REQUEST bit and did not clear the swap_file_number in the filemap or in the StoreEntry, so the swap file could get unlinked later when it was really released. - Fixed FTP so that ';type=X' specifically sets the HTTP reply content-type and content-encoding (Henrik Nordstrom). - Removed 'icon_content_type' configuration option. Content types now taken from mime.conf (Henrik Nordstrom). - Added additional memory malloc tracing and memory leak detection. Use --enable-xmalloc-debug-trace configure option and -m command line option (Henrik Nordstrom). Changes to squid-1.2.beta14 (Feb 6, 1998): - Replaced snmplib free() calls with xfree(). - Changed the 'net_db_name' hash table structure to make it easier to move names from one network to another (copied from 1.1 code). - Filled in some of the config dump routines (dump_acl, dump_acl_access). - Full memory debugging option (--enable-xmalloc-debug-trace) (Henrik Nordstrom). - Filled-in and clarified many squid.conf comments (Oskar Pearson). - Fixed up handling of SWAP_LOG_DEL swap.state entries. Changes to squid-1.2.beta13 (Feb 4, 1998): - NOTE: With this version the "swap.state" file format has changed. Running this version for the first time will cause your current cache contents to be lost! - NOTE: this version still has the bug where we don't rewind a swapout file and rewrite the swap meta data. Objects larger than 8KB will be lost when rebuilding from the swap files. - Combined various interprocess communication setup functions into ipcCreate(). - Removed some leftover ICP_HIT_OBJ things. - Removed cacheinfo and proto_count() and friends; these are to be replaced in functionality by StatCounters and 5/60 minute average views via cachemgr. - Fixed --enable-acltree configure message (Masashi Fujita). - Fixed no reference to @LIB_MALLOC@ in src/Makefile.in (Masashi Fujita). - Fixed building outside of source tree (Masashi Fujita). - FTP: Format NLST listings, and inform the user that the NLST (plain) format is available when we find a LIST listing that we don't understand (Henrik Nordstrom) - FTP: Use SIZE on Binary transfers, and not ASCII. The condition was inversed, making squid use SIZE on ASCII transfers (Henrik Nordstrom). - Enable virtual and Host: based acceleration in order to be able to use Squid as a transparent proxy without breaking either virtual servers or clients not sending Host: header the order of the virtual and Host: based acceleration needs to be swapped, giving Host: a higher precendence than virtual host (Henrik Nordstrom). - Use memmove/bcopy as detected by configure Some systems does not have memmove, but have the older bcopy implementation (Henrik Nordstrom). - Completely rewritten aiops.c that creates and manages a pool of threads so thread creation overhead is eliminated (SLF). - Lots of mods to store.c to detect and cancel outstanding ASYNC ops. Code is not proven exhaustive and there are definately still cases to be found where outstanding disk ops aren't cancelled properly (SLF). - Changes to call interface to a few routines to support disk op `tagging', so operations can be cleanly cancelled on store_abort()s (SLF). - Implementation of swap.state files as transaction logs. Removed objects are now noted with a negative object size. This allows reliatively clean rebuilds from non-clean shutdowns (SLF). - Now that the swap.state files are transaction logs, there's now no need to validate by stat()ing. All the validation procedure does is now just set the valid bit AFTER all the swap.state files have been read, because by that time, only valid objects can be left. Object still need to be marked invalid when reading the swap.state file because there's no guarantee the file has been retaken or deleted (SLF). - An fstat() call is now added after every storeSwapInFileOpened() so object sizes can be checked. Added code to storeRelease() the object if the sizes don't match (SLF). - #defining USE_ASYNC_IO now uses the async unlink() rather than unlinkd() (SLF). - #defining MONOTONIC_STORE will support the creation of disk objects clustered into directories. This GREATLY improves disk performance (factor of 3) over old `write-over-old-object' method. If using the MONOTONIC_STORE, the {get/put}_unusedFileno stack stuff is disabled. This is actually a good thing and greatly reduces the risk of serving up bad objects (SLF). - Fixed unlink() in storeWriteCleanLogs to be real unlink() rather than ASYNC/unlinkd unlinks. swap.state.new files were being removed just after they were created due to delayed unlinks (SLF). - Disabled various assertions and made these into debug warning messages to make the code more stable until the bugs can be tracked down (SLF). - Added most of Michael O'Reilly's patches which included many bug fixes. Ask him for full details (SLF). - Moved aio_check_callbacks in comm_{poll|select}(). It was called after the fdset had been built which was wrong because the callbacks were changing the state of the read/write handlers prior to the poll/select() calls (SLF). - Fixed ARP ACL memory leaks (Dale). - Eliminated URL and SHA cache keys. Cache keys will always be MD5's now. - Fixed up store swap meta data. - Changed swap.state logs to a binary format. - The swap.state logs are written transaction-style. Changes to squid-1.2.beta12 (Jan 30, 1998): - Added metadata headers to cache swap files. This is an incompatible change with previous versions. Running this version for the first time will cause your current cache contents to be lost. - -D_REENTRANT when linking with -lpthreads (Henrik Nordstrom) - Show symlink destinations as a hyperlink in FTP listings (Henrik Nordstrom) - Fixed not allocating enough space for rewriting URLs with the Host: header (Eric Stern). - Year-2000 fixes (Arjan de Vet). - Fixed looping for cache hits on HEAD requests. - Fixed parseHttpRequest() coredump for "GET http://foo HTTP/1.0\r\n\r\n\r\n" Changes to squid-1.2.beta11 (Jan 6, 1998): - Fixed fake 'struct rusage' definition which prevented compling on Solaris 2.4. - Fixed copy-by-ref bug for request->headers in clientRedirectDone() (Michael O'Reilly). - Workaround for Solaris pthreads closing FD 0 upon fork() (Michael O'Reilly). - Fixed shutdown bug with outgoing UDP sockets; we need to disable their read handlers. - For comm_poll(), use the fast 50 msec timeout only when USE_ASYNC_IO is defined. - Fixed pointer bug when freeing AS# ACL entries. - Fixed forgetting to reset Config.npeers to zero in free_peer(). - Fixed ICP bug causing excessive TIMEOUTs with sibling neighbors. We must call the ICP reply callback even for sibling misses. - Fixed some dnsserver-related reconfigure bugs. Need to use cbdataLock, etc in fqdncache.c. Also don't want to use ipcacheQueueDrain() and fqdncacheQueueDrain(). - Fixed persistent connection bug. We were incorrectly deciding that non-200 replies without content-length would not have a reply body. - Fixed intAverage() precedence bug. - Fixed memmove() 'len' arg bug. - Changed algorithm for determining alive/dead state of peers. Instead of using a fixed number of unacknowledged ICP replies, it is now based on timeouts. If there are no ICP replies received from a peer within 'dead_peer_timeout' seconds, then we call it dead. - Added calls to getCurrentTime() in comm_{select,poll}_incoming() when ALARM_UPDATES_TIME is not being used. - Fixed shutdown bug when the incoming and outgoing ICP socket is the same file descriptor. - Added buffered writes for storeWriteCleanLogs() (Stewart Forster). - Patches for Qnx4 (Jean-Claude MICHOT). - Fixed returning void functions which seems to be a GCC-ism. - New configure script options (Henrik Nordstrom): --enable-new-storekey=[sha|md5(|url)] (was --enable-hashkey) --enable-acltree --enable-icmp --enable-delay-hack --enable-useragent-log --enable-kill-parent (this should be named -hack) --enable-snmp --enable-time-hack --enable-cachemgr-hostname[=hostname] (new) --enable-arp-acl (new) - Added Doug Lea malloc-2.6.4 to the distribution, so that people easily can try a decent malloc package if they syspect their malloc is broken. --enable-dlmalloc (Henrik Nordstrom). - Made XMALLOC_DEBUG_COUNT working again. Requires a small stub function (Henrik Nordstrom). - Removed top-level Makefile. People must now run 'configure' before 'make'. - Fixed checkFailureRatio() implementation. - Made 'squid -z' behave like the 1.1 version. Changes to squid-1.2.beta10 (Jan 1, 1998): - Fixed content-length bugs for 204 replies, 304 replies, and HEAD requests (Henrik Nordstrom). - Fixed errorAppendEntry() bug in gopherReadReply(). - Basic support for FTP URL typecodes (;type=X). - Support for access controls based on ethernet MAC addresses (Dale). - Initial URN support; see http://squid.nlanr.net/Squid/urn-support.html - Fixed client-side persistent connections for objects with bad content lengths (Henrik Nordstrom). - Fixed bad call to storeDirUpdateSwapSize() for objects which never reach SWAPOUT_DONE state. - Fixed up poll() #defines in squid.h (Stewart Forster). - Changed poll() timeout from 1000 msec to 50 msec for better performance under low load (Stewart Forster). - Changed storeWriteCleanLogs() to write objects in the LRU list order instead of the random hash table order. - Fixed FTP bug when data socket connections fail or timeout. - Reuse FTP data connection when possible (Henrik Nordstrom). - Added configure options (Henrik Nordstrom) --enable-store-key=sha|md5 --enable-xmalloc-statistics --enable-xmalloc-debug --enable-xmalloc-debug-count --async-io - Fixed confusing with the use/meaning of ERR_CANNOT_FORWARD by creating ERR_FORWARDING_DENIED and changing the content of the ERR_CANNOT_FORWARD text. - Fixed pipeline request bug from using strdup() (Henrik Nordstrom). - Call clientReadRequest() directly instead of commSetSelect() for pipelined requests (Henrik Nordstrom). - Fixed 4k page leak in icpHandleIMSReply(); - Renamed 'icp*' functions to 'client*' names in client_side.c. Changes to squid-1.2.beta8 (Dec 2, 1997): - Fixed accessLogLog() to log ident from Proxy-Authorization request header (BoB Miorelli). - Fixed #includes, prototypes, etc. in SNMP source files. - Moved 'POLLRDNORM' and 'POLLWRNORM' macro checks from include/config.h.in to src/squid.h - Moved 'num32' typedefs from src/typedefs.h to include/config.h.in. - Moved snmplib/md5.c to lib/md5.c. - Added MD5 cache key support. - Removed xmalloc() return check in uudeocde.c - Added 'ifdef' support to cf_gen.c for optional code (e.g. SNMP) - Changed 'client' program to provide easier cache manager access, e.g.: 'client mgr:info' - Fixed 'client' to send 'Connection' instead of 'Proxy-Connection' for simulated keep-alive requests. - Removed 'fd' arg from clientProcess* functions. - Fixed bugs from using errorSend() on persistent/pipelined client connections. A latter request should not be allowed to write to the client fd until the current request completes. Now use errorAppendEntry() for such situations. - Fixed content-length bugs. We were using content-length == 0 to also indicate a lack of content-length reply header. But 'content-length: 0' might appear in a reply, so now use -1 to indicate that no content length given. - Split up clientProcessRequest() into smaller chunks so it might be easier to follow. - renamed various client_side.c functions to start with 'client' instead of 'icp'. - Fixed a 'cbdata leak' from the comm.c close handlers. - Fixed a 'cbdata leak' from the comm.c connect routines. - Fixed comm_select() and comm_poll() to stop looping on the incoming HTTP/ICP sockets. If there are fewer than 7 FD's ready for I/O, the incoming sockets might not get service, so comm_select() would be called for up to 7 times until the 'incoming_counter' was incremented enough to trigger a call to comm_select_incoming(). Now we make sure comm_select_incoming() gets called if select returns less than 7 ready FD's. - Added errorpage '%B' token to generate FTP URLs with a '%2f' inserted at the start of the url-path. calls ftpUrlWith2f(). (Henrik Nordstrom). - Changed fqdncache.c to use LRU double-linked list instead of qsort() for replacement and cachemgr output. - Changed ipcache.c to use LRU double-linked list instead of qsort() - Changed hash_insert() and hash_join() to return void. for replacement and cachemgr output. - Moved StoreEntry->method member to MemObject->method. - Made StoreEntry->flags 16 bits. - Made StoreEntry->refcount 16 bits. - Changed URL-based public cache key to always include the request method. Changes to squid-1.2.beta7 (Nov 24, 1997): - Fixed poll() for Linux (David Luyer). - SHA optimizations (David Luyer). - Fixed errno clashes with macro on Linux (David Luyer). - Fixed storeDirCloseSwapLogs(); logs might not be open. - Fixed storeClientCopy2() bug. Detect when there is no more data to send for objects in STORE_OK state. - Fixed FTP truncation bug when ftpState->size == 0, e.g. especially directory listings. - Mega FTP fix from Henrik Nordstrom. A better job of implementing the '%2f' hack. - Fixed some pipelined request bugs. storeClientCopy() was being given the wrong StoreEntry, and we had a race condition which is now handled by storeClientCopyPending(). - Added initial SNMP support. Changes to squid-1.2.beta6 (Nov 13, 1997): - Fixed Authorized responses getting swapped out when they don't have Proxy-Revalidate reply header. - Fixed Proxy Authentication support. We never sent back a 407 reply, and were incorrectly incrementing the passwd before comparing it. - Fixed stat()ing pathnames for default values before parsing config file (Ron Gomes). - Fixed logging request and response headers on separate lines (Ron Gomes). - Fixed FTP Authentication message (Henrik Nordstrom). - Changed Proxy Authentication to trigger a reread of the passwd file if a password check fails (Henrik Nordstrom). - Changed FTP to retry the first CWD with a leading slash if it fails without one. Changes to squid-1.2.beta5 (Nov 6, 1997): - Track the 'keep-alive ratio' for a peer as the ratio of the number of replies including 'Proxy-Connection: Keep-Alive' compared to the number of requests sent. If the peer does not support Persistent connections then this ratio will tend toward zero. If the ratio is less than 50% after 10 requests then we'll stop sending Keep-Alive. - Proper support for %nn escapes in FTP, and numerous other fixes (Henrik Nordstrom). - Support for Secure Hash Algorithm and framework for other hash functions as cache keys. - Fixed SSL snprintf() bug which broke SSL proxying. - Fixed store_dir swap log bug from reconfigure (SIGHUP). - Fixed LRU Reference Age bug. The arg to pow() must be minutes, not seconds. Changes to squid-1.2.beta4 (Oct 30, 1997): - Fixed DST bug in rfc1123.c - Changed default http_accel_port to 80. - added errorCon() as a ErrorState constructor function (Max Okumoto). - Added ERR_FTP_FAILURE message for ftpFail(). - For FTP, the timeout callback must be moved to the 'data' descriptor when data transfer begins. Otherwise we are likely to get a timeout on the control descriptor. - Fixed double-free bug in httpRequestFree(). - Fixed store_swap_size counting bug in storeSwapOutHandle(). Changes to squid-1.2.beta3 (Oct 29, 1997): - Initialize _res.options to RES_DEFAULT in dnsserver.c. - Fix assertions which assumed 4-byte pointers. - Fix missing % in fqdncache.c snprintf(). Changes to squid-1.2.beta2 (Oct 28, 1997): - Fixed aiops.c and async_io.c so that they actually compile with USE_ASYNC_IO (Arjan de Vet). - Fixed errState->errno causing problems with some macros (Michael O'Reilly). - Fixed memory leaks in pconn.c (Max Okumoto). - Enhanced 'client' program with 'ping' behaviour (Ron Gomes). - Fixed InvokeHandlers() from calling memCopy() for ALL store_client's with callbacks. A store_client might be reading from disk. - Rewrote storeMaintainSwapSpace(). No longer will we scan one bucket at a time. Instead we'll maintain a single LRU list. When an object is 'touched' we move it to the top of this list. When we need disk space, we delete from the bottom. - Removed storeGetSwapSpace(). Changes to squid-1.2.beta1 (): - Reworked storage manager to not keep objects in memory during transit. In other words, no separate NOVM distribution. - Lots of cleanup and debugging for beta release. - Use snprintf() everywhere instead of sprintf(). - The 'in_memory' hash table has been replaced with a doubly-linked list. New objects are added to the head of the list. When memory space is needed, old objects are purged from the tail of the list. Changes to squid-1.2.alpha7 (): - fixes fixes fixes. - Made Arjan's PROXY_AUTH ACL patch standard. Changes to squid-1.2.alpha6 (): - Simpler cacheobj implementation. - persistent connection histogram - SERVER-SIDE PERSISTENT CONNECTIONS: - Added pconn.c - Addec Cofig.Timeout.pconn; default 120 seconds - Added httpState->flags - Added flags arg to httpBuildRequestHeader() - Added HTTP_PROXYING and HTTP_KEEPALIVE flags - Added 'Connection' to allowed HTTP headers (http-anon.c) - Added 'Proxy-Connection' to allowed HTTP headers (http-anon.c) - Merged proxyhttpStart() with httpStart() and created new httpBuildState(). - New httpPconnTransferDone() detects end-of-data on persistent connections. Changes to squid-1.2.alpha5 (): - New configuration system. Everything is generated from 'cf.data.pre', including the main parser, setting defaults, outputting current values, and freeing memory. This also involved moving some of the local data structures (e.g. struct _acl *AclList in acl.c) to the Config structure. (Max Okumoto) - No more '/i' for regular expressions. Now insert a '-i' to switch to case-insensitive. Use '+i' for case-sensitive. - When you have a variable named the same as its type, sizeof() gets the wrong one (fde). - Need to flush unbuffered logs before fork(). - Added two fields swap log: refcount and e->flag. - Removed all the .h files for each .c file. Now #include stuff is in either: defines.h, enums.h, typedefs.h, structs.h, or protos.h, globals.h. This greatly reduces dependencies between the various source files. - globals.c is generated from globals.h by a Perl script. - Started customizable error texts. Changes to squid-1.2.alpha4 (): - New MIME configuration, regular expression based - Added request_timeout config option - Multiple HTTP sockets (Lincoln Dale). - Moved 'fds_are_n_free' check to httpAccept(). - s/USE_POLL/HAVE_POLL/; make poll() default if available. - Changed storeRegister to use offsets and make immediate callbacks if appropriate. - Removed icpDetectClientClose(). Some of that functionality goes into clientReadRequest() and the rest into httpRequestFree(). - Moved IP lookups to commConnect stuff. - Added support for retrying connect(). - New inline debug() macro (David Luyer). - Replace frequent gettimeofday() calls with alarm(3) based clock. Need to add more gettimeofday() calls to get back high-resolution timestamp logging (Andres Kroonmaa). - Added support for Cache-control: proxy-revalidate; based on squid-1.1 patch from Mike Mitchell. Changes to squid-1.2.alpha3 (): - Implemented persistent connections between clients and squid. - Moved various FD tables (comm.c, fdstat.c, disk.c) to a single table in fd.c. - Removed use of FD as an identifier in certain callback operations (ipcache, fqdncache). - General code cleanup. - Fixed typedefs for callback functions. - Removed FD lifetime/timeout dichotomy. Now we only have timeouts, however the lifetime concept/keyword may still linger in certain places. - Change Makefile 'realclean' target to 'distclean' - Changed config file parsing of time specifications to use parseTimeLine(). - Removed storetoString.c Changes to squid-1.2.alpha2 (): - Merged squid-1.1.9, squid-1.1.10 changes Changes to squid-1.2.alpha1 (): - Unified peer selection algorithm. - aiops.c and aiops.h are a threaded implementation of asynchronous file operations (Stewart Forster). - async_io.c and async_io.h are complete rewrites of the old versions (Stewart Forster). - Rewrote all disk file operations of squid to support the idea of callbacks except where not required (Stewart Forster). - Background validation of 'tainted' swap log entries (Stewart Forster). - Modified storeWriteCleanLog to create the log file using the open/write rather than fopen/printf (Stewart Forster). - Added the EINTR error response to handle badly interrupted system calls (Stewart Forster). - UDP_HIT_OBJ not supported, removed. - Different sized 'cache_dirs' supported. ============================================================================== squid3-3.5.12/INSTALL000066400000000000000000000014451262763202500140540ustar00rootroot00000000000000/* * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. */ To build and install the Squid Cache, type: % ./configure --prefix=/usr/local/squid % make all % make install To run a Cache, you will need to: 1. customize the squid.conf configuration file: % vi /usr/local/squid/etc/squid.conf 2.

Squid has many features, but only a few of them are useful at the beginning. Use this only if you have quite a simple setup. After you retrieved, compiled and installed the Squid software (see INSTALL in the same directory), you have to configure the squid.conf file. This is the list of the values you *need* to change, because no sensible defaults could be defined. Do not touch the other variables for now. We assume you have installed Squid in the default location: /usr/local/squid Uncomment and edit the following lines in /usr/local/squid/etc/squid.conf: ============================================================================== acl, http_access Access control lists. This is important because it prevents people from stealing your network resources. Edit the "localnet" ACL definition to be your LAN network address ranges in CIDR format. For instance: acl localnet src 192.168.10.0/24 Add any other ACLs and edit the http_access lines to match your policy requirements for use of the proxy. See Squid FAQ for more details. cache_mgr Put here the e-mail address of the manager. ============================================================================== Some configuration lines which are optional but may be needed. visible_hostname The publicly visible host name advertised for the cache. This will be used for URLs generated by Squid for clients to fetch certain objects from. cache_effective_user If building your own squid; use ./configure --with-default-user=X You must start Squid as root, with a safe user and group to run as after startup (typically "nobody" and "nogroup"). Do not use "root", for security reasons. cache_dir ufs /usr/local/squid/var/cache 100 16 256 Add here (first number, here 100) the amount of hard disk space (in megabytes) to devote to caching. The default is to store files in 256 MB of memory instead of disk Linux : use aufs instead of ufs BSD : use diskd instead of ufs cache_mem 256 MB How much memory to allocate for cached files in-memory. The default is shown. cache_peer, never_direct/always_direct If you have a parent cache, put it here. The administrators of the parent cache typically provided you with instructions. You should always ask permission before adding a parent cache. See also the never_direct/always_direct directives. ============================================================================== After editing squid.conf to your liking, run Squid from the command line TWICE: To create any disk cache_dir configured: % /usr/local/squid/sbin/squid -z To start squid: % /usr/local/squid/sbin/squid Check in the cache.log (/usr/local/squid/var/logs/cache.log) that everything is all right. Once Squid created all its files (it can take several minutes on some systems), test it with echoping or a regular Web client. By default, your Squid will run on port 3128. See the Squid FAQ for more details. Once you have Squid working from the command line, tell your Unix to start Squid at startup (it depends heavily on the Unix you use, you'll typically have to modify something in a /etc/rc_something). ============================================================================== /* * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. */ This quick start file written by: Stephane Bortzmeyer and Duane Wessels. squid3-3.5.12/README000066400000000000000000000024001262763202500136730ustar00rootroot00000000000000 SQUID Web Proxy Cache http://www.squid-cache.org/ ------------------------------------------------------------------------- Copyright (C) 1996-2015 The Squid Software Foundation and contributors Squid software is distributed under GPLv2+ license and includes contributions from numerous individuals and organizations.

Squid 3.5.12 release notes

Squid Developers

This document contains the release notes for version 3.5 of Squid. Squid is a WWW Cache application developed by the National Laboratory for Applied Network Research and members of the Web Caching community.

1. Notice

2. Major new features since Squid-3.4

3. Changes to squid.conf since Squid-3.4

4. Changes to ./configure options since Squid-3.4

5. Regressions since Squid-2.7

6. Copyright

1. Notice

The Squid Team are pleased to announce the release of Squid-3.5.12.

This new release is available for download from http://www.squid-cache.org/Versions/v3/3.5/ or the mirrors.

Some interesting new features adding system flexibility have been added along with general improvements all around. While this release is not fully bug-free we believe it is ready for use in production on many systems.

We welcome feedback and bug reports. If you find a bug, please see http://wiki.squid-cache.org/SquidFaq/BugReporting for how to submit a report with a stack trace.

1.1 Known issues

Although this release is deemed good enough for use in many setups, please note the existence of open bugs against Squid-3.5.

1.2 Changes since earlier releases of Squid-3.5

The 3.5 change history can be viewed here.

1.3 Copyright disclaimer adjustments

Squid sources are now administered by the Squid Software Foundation on behalf of the Squid Project and community.

This version of Squid contains initial changes to streamline copyright declarations in Squid sources and related metafiles. No functionality or licensing changes are intended.

Once completed, the changes will consistently declare Squid contributors (listed in CONTRIBUTORS and represented by the Squid Software Foundation) as Squid copyright owners while referring the reader to the COPYING file for GPL licensing details. The boilerplate with the above information is provided.

These changes do not affect copyright rights of individuals or organizations. We are simply confirming the fact that there are many Squid copyright owners, just like there are many Linux kernel copyright owners. We are also providing a simple, consistent way to document that fact.

2. Major new features since Squid-3.4

Squid 3.5 represents a new feature release above 3.4.

The most important of these new features are:

  • Support libecap v1.0
  • Authentication helper query extensions
  • Support named services
  • Upgraded squidclient tool
  • Helper support for concurrency channels
  • Native FTP Relay
  • Receive PROXY protocol, Versions 1 & 2
  • Basic authentication MSNT helper changes

Most user-facing changes are reflected in squid.conf (see below).

2.1 Support libecap v1.0

Details at http://wiki.squid-cache.org/Features/eCAP.

The new libecap version allows Squid to better check the version of the eCAP adapter being loaded as well as the version of the eCAP library being used.

Squid-3.5 can support eCAP adapters built with libecap v1.0, but no longer supports adapters built with earlier libecap versions due to API changes.

2.2 Authentication helper query extensions

Details at http://www.squid-cache.org/Doc/config/auth_param/.

The new key_extras parameter allows sending of additional details to the authentication helper beyond the minimum required for the HTTP authentication. This is primarily intended to allow switching of authentication databases based on criteria such as client IP subnet, Squid receiving port, or in reverse-proxy the requested domain name.

In theory any logformat code may be used, however only the codes which have available details at the time of authentication will send any meaningful detail.

2.3 Support named services

Details at http://wiki.squid-cache.org/MultipleInstances.

Terminology details at http://wiki.squid-cache.org/Features/SmpScale#Terminology.

The command line option -n assigns a name to the Squid service instance to be used as a unique identifier for all SMP processes run as part of that instance. This allows multiple instances of Squid service to be run on a single machine without background SMP systems such as shared memory and inter-process communication becoming confused or requiring additional configuration.

A service name is always used. When the -n option is missing from the command line the default service name is squid.

When multiple instances are being run the -n service name is required to target all other options such as -z or -k commands at the correct service.

The squid.conf macro ${service_name} is added to provide the service name of the process parsing the config.

2.4 Upgraded squidclient tool

Details at http://www.squid-cache.org/Versions/v3/3.5/manuals/squidclient.html.

The squidclient has begun the process of upgrading to support protocols other than HTTP.

Debug levels

The tool displays the server response message on STDOUT unless the -q command line option is used. Error messages will be output to STDERR. All other possible output is considered debug and output to STDERR using a range of debug verbosity levels (currently 1, 2 and 3).

When the -v command line option is used debugging is enabled. The level of debug display is raised for each repetition of the option.

PING

When --ping is given the tool will send its message repeatedly using whichever protocol that message has been formatted for. Optional parameters to limit the number of pings and their frequency are available.

Older tool versions also provide this feature but require the loop count parameter to be set to enable use of the feature.

HTTPS

When Squid is built with the GnuTLS encryption library the tool is able to open TLS (or SSL/3.0) connections to servers.

The --https option enables TLS using default values.

The --cert option specifies a file containing X.509 client certificate and private key in PEM format to be loaded for use. Multiple certificates are supported and the option may be used multiple times to load certificates. The default is not to use a client certificate.

The --params option specifies a library specific set of parameters to be sent to the library for configuring the security context. See http://gnutls.org/manual/html_node/Priority-Strings.html for available GnuTLS parameters.

The --trusted-ca option specifies a file in PEM format containing one or more Certificate Authority (CA) certificates used to verify the remote server. This option may be used multiple times to load additional CA certificate lists. The default is not to use any CA, nor trust any server.

Anonymous TLS (using non-authenticated Diffi-Hellman or Elliptic Curve encryption) is available with the --anonymous-tls option. The default is to use X.509 certificate encryption instead.

When performing TLS/SSL server certificates are always verified, the results shown at debug level 3. The encrypted type is displayed at debug level 2 and the connection is used to send and receive the messages regardless of verification results.

2.5 Helper support for concurrency channels

Helper concurrency greatly reduces the communication lag between Squid and its helpers allowing faster transaction speeds even on sequential helpers.

The Digest authentication, Store-ID, and URL-rewrite helpers packaged with Squid have been updated to support concurrency channels. They will auto-detect the channel-ID field and will produce the appropriate response format. With these helpers concurrency may now be set to 0 or any higher number as desired.

2.6 Native FTP Relay

Details at http://wiki.squid-cache.org/Features/FtpRelay.

Squid is now capable of accepting native FTP commands and relaying native FTP messages between FTP clients and FTP servers. Native FTP commands accepted at ftp_port are internally converted or wrapped into HTTP-like messages. The same happens to Native FTP responses received from FTP origin servers. Those HTTP-like messages are shoveled through regular access control and adaptation layers between the FTP client and the FTP origin server. This allows Squid to examine, adapt, block, and log FTP exchanges. Squid reuses most HTTP mechanisms when shoveling wrapped FTP messages. For example, http_access and adaptation_access directives are used.

FTP Relay is a new, experimental, complex feature that has seen limited production exposure. Some Squid modules (e.g., caching) do not currently work with native FTP proxying, and many features have not even been tested for compatibility. Test well before deploying!

Native FTP proxying differs substantially from proxying HTTP requests with ftp:// URIs because Squid works as an FTP server and receives actual FTP commands (rather than HTTP requests with FTP URLs).

FTP Relay highlights:

  • Added ftp_port directive telling Squid to relay native FTP commands.
  • Active and passive FTP support on the user-facing side; require passive connections to come from the control connection source IP address.
  • IPv6 support (EPSV and, on the user-facing side, EPRT).
  • Intelligent adaptation of relayed FTP FEAT responses.
  • Relaying of multi-line FTP control responses using various formats.
  • Support relaying of FTP MLSD and MLST commands (RFC 3659).
  • Several Microsoft FTP server compatibility features.
  • ICAP/eCAP support (at individual FTP command/response level).
  • Optional "current FTP directory" tracking with the assistance of injected (by Squid) PWD commands (cannot be 100% reliable due to symbolic links and such, but is helpful in some common use cases).
  • No caching support -- no reliable Request URIs for that (see above).

2.7 Receive PROXY protocol, Versions 1 & 2

More info at http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt

PROXY protocol provides a simple way for proxies and tunnels of any kind to relay the original client source details without having to alter or understand the protocol being relayed on the connection.

Squid currently supports receiving HTTP traffic from a client proxy using this protocol. An http_port which has been configured to receive this protocol may only be used to receive traffic from client software sending in this protocol. HTTP traffic without the PROXY header is not accepted on such a port.

The accel and intercept options are still used to identify the HTTP traffic syntax being delivered by the client proxy.

Squid can be configured by adding an http_port with the require-proxy-header mode flag. The proxy_protocol_access must also be configured with src ACLs to whitelist proxies which are trusted to send correct client details.

Forward-proxy traffic from a client proxy: 

 acl frontend src 192.0.2.1
 http_port 3128 require-proxy-header
 proxy_protocol_access allow frontend

Intercepted traffic from a client proxy or tunnel: 

 acl frontend src 192.0.2.2
 http_port 3128 intercept require-proxy-header
 proxy_protocol_access allow frontend

Reverse-proxy traffic from a frontend load balancer sending PROXY protocol: 

 acl frontend src 192.0.2.3
 http_port 3128 accel require-proxy-header
 proxy_protocol_access allow frontend

Known Issue: Use of require-proxy-header on https_port and ftp_port is not supported.

2.8 Basic authentication MSNT helper changes

The authentication helper previously known as basic_msnt_auth has been deprecated and renamed to basic_smb_lm_auth to reflect that it only performs SMB LanMan protocol(s) instead of modern MS authentication protocols.

The basic_smb_lm_auth helper has been remodelled and no longer uses configuration files. The Doman Controller servers are now configured via command line parameters and user credentials are looked up in each DC in the order configured until one matches or all have confirmed a non-match.

The MSNT-multi-domain helper provides the same functionality and is also deprecated. It will be removed in the Squid-3.6 series.

3. Changes to squid.conf since Squid-3.4

There have been changes to Squid's configuration file since Squid-3.4.

Squid supports reading configuration option parameters from external files using the syntax parameters("/path/filename"). For example: 

    acl whitelist dstdomain parameters("/etc/squid/whitelist.txt")

The squid.conf macro ${service_name} is added to provide the service name of the process parsing the config.

There have also been changes to individual directives in the config file.

This section gives a thorough account of those changes in three categories:

3.1 New tags

collapsed_forwarding

Ported from Squid-2 with no configuration or visible behaviour changes. Collapsing of requests is performed across SMP workers.

ftp_client_idle_timeout

New directive controlling how long to wait for an FTP request on a client connection to Squid ftp_port.

Many FTP clients do not deal with idle connection closures well, necessitating a longer default timeout (30 minutes) than client_idle_pconn_timeout used for incoming HTTP requests (2 minutes).

The current default may be changed as we get more experience with FTP relaying.

ftp_port

New configuration directive to accept and relay native FTP commands. Typically used for port 21 traffic. By default, native FTP commands are not accepted.

proxy_protocol_access

New directive to control which clients are permitted to open PROXY protocol connections on a port flagged with require-proxy-header.

send_hit

New configuration directive to enable/disable sending cached content based on ACL selection. ACL can be based on client request or cached response details.

sslproxy_cert_sign_hash

New directive to set the hashing algorithm to use when signing generated certificates.

sslproxy_session_cache_size

New directive which sets the cache size to use for TLS/SSL sessions cache.

sslproxy_session_ttl

New directive to specify the time in seconds the TLS/SSL session is valid.

store_id_extras

New directive to send additional lookup parameters to the configured Store-ID helper program. It takes a string which may contain logformat %macros.

The Store-ID helper input format is now: 

         [channel-ID] url [extras]

The default value for extras is: "%>a/%>A %un %>rm myip=%la myport=%lp"

store_miss

New configuration directive to enable/disable caching of MISS responses. ACL can be based on any request or response details.

url_rewrite_extras

New directive to send additional lookup parameters to the configured URL-rewriter/redirector helper program. It takes a string which may contain logformat %macros.

The url rewrite and redirector helper input format is now: 

         [channel-ID] url [extras]

The default value for extras is: "%>a/%>A %un %>rm myip=%la myport=%lp"

3.2 Changes to existing tags

acl

Deprecated type tag. Use type note with 'tag' key name instead.

New type adaptation_service to match the name of any icap_service, ecap_service, adaptation_service_set, or adaptation_service_chain that Squid has used (or attempted to use) for the HTTP transaction so far.

New type at_step to match the current SSL-Bump processing step. Never matches and should not be used outside of ssl_bump.

New types ssl::server_name and ssl::server_name_regex to match server name from various sources (CONNECT authority name, TLS SNI domain, or X.509 certificate Subject Name).

auth_param

New parameter key_extras to send additional parameters to the authentication helper.

cache_dir

New support for larger than 32KB objects in both rock type cache and shared memory cache.

New slot-size=N option for rock cache to specify the database slot/page size when small slot sizes are desired. The default and maximum slot size is 32KB.

Removal of old rock cache dir followed by squid -z is required when upgrading from earlier versions of Squid.

COSS storage type is formally replaced by Rock storage type. COSS storage type and all COSS specific options are removed.

cache_peer

New standby=N option to retain a set of N open and unused connections to the peer at virtually all times to reduce TCP handshake delays.

These connections differ from HTTP persistent connections in that they have not been used for HTTP messaging (and may never be). They may be turned into persistent connections after their first use subject to the same keep-alive critera any HTTP connection is checked for.

Squid-2 option idle= replaced by standby=.

NOTE that standby connections are started earlier and available in more circumstances than squid-2 idle connections were. They are also spread over all IPs of the peer.

configuration_includes_quoted_values

Regex pattern values cannot be parsed in parts of squid.conf when this directive is configured to ON. Instead of quoted strings Squid now accepts regex \-escaped characters (including escaped spaces) in all regex patterns.

external_acl_type

New format code %ssl::>sni to send SSL client SNI.

New format code %ssl::<cert_subject to send SSL server certificate DN.

New format code %ssl::<cert_issuer to send SSL server certificate issuer DN.

New format code %un to send any available user name (requires 3.5.7 or later).

New response kv-pair clt_conn_tag= to associates a given tag with the client TCP connection.

forward_max_tries

Default value increased to 25 destinations to allow better contact and IPv4 failover with domains using long lists of IPv6 addresses.

ftp_epsv

Converted into an Access List with allow/deny value driven by ACLs using Squid standard first line wins matching basis.

The old values of on and off imply allow all and deny all respectively and are now deprecated. Do not combine use of on/off values with ACL configuration.

http_port

protocol= option altered to accept protocol version details. Currently supported values are: HTTP, HTTP/1.1, HTTPS, HTTPS/1.1

New option require-proxy-header to mark ports receiving PROXY protocol version 1 or 2 traffic.

https_port

protocol= option altered to accept protocol version details. Currently supported values are: HTTP, HTTP/1.1, HTTPS, HTTPS/1.1

logformat

New format code %credentials to log the client credentials token.

New format code %ssl::>sni to TLS client SNI sent to Squid.

New format code %tS to log transaction start time in "seconds.milliseconds" format, similar to the existing access.log "current time" field (%ts.%03tu) which logs the corresponding transaction finish time.

New format codes %<rs and %>rs to log request URL scheme from client or sent to server/peer respectively.

New format codes %<rd and %>rd to log request URL domain from client or sent to server/peer respectively.

New format codes %<rP and %>rP to log request URL port from client or sent to server/peer respectively.

ssl_bump

Bumping 'modes' redesigned as 'actions' and ACLs evaluated repeatedly in a number of steps.

Renamed server-first as bump action.

Renamed none as splice action.

New actions peek and stare to receive client or server certificate while preserving the ability to later decide between bumping or splicing the connections later.

New action terminate to close the client and server connections.

url_rewrite_program

New response kv-pair clt_conn_tag= to associates a given tag with the client TCP connection.

3.3 Removed tags

cache_dns_program

DNS external helper interface has been removed. It was no longer able to provide high performance service and the internal DNS client library with multicast DNS cover all modern use-cases.

dns_children

DNS external helper interface has been removed.

hierarchy_stoplist

Removed. The old directive values prohibiting CGI and dynamic content going to cache_peer are no longer relevant.

The functionality provided by this directive can be configured using always_direct allow if still needed.

4. Changes to ./configure options since Squid-3.4

There have been some changes to Squid's build configuration since Squid-3.4.

This section gives an account of those changes in three categories:

4.1 New options

BUILDCXX=

Used when cross-compiling Squid.

The path and name of a compiler for building cf_gen and related tools used in the compile process.

BUILDCXXFLAGS=

Used when cross-compiling Squid.

C++ compiler flags used for building cf_gen and related tools used in the compile process.

--without-gnutls

New option to explicitly disable use of GnuTLS encryption library. Use of this library is auto-enabled if v3.1.5 or later is available.

It is currently only used by the squidclient tool.

--without-mit-krb5

New option to explicitly disable use of MIT Kerberos library. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

--without-heimdal-krb5

New option to explicitly disable use of Hiemdal Kerberos library. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

--without-gnugss

New option to explicitly disable use of GNU GSSAPI library for Kerberos. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

4.2 Changes to existing options

--enable-icap-client

Deprecated. ICAP client is now auto-enabled. Use --disable-icap-client to disable if you need to.

4.3 Removed options

--disable-internal-dns

DNS external helper interface has been removed. It was no longer able to provide high performance service and the internal DNS client library with multicast DNS cover all modern use-cases.

--enable-ssl

Removed. Use --with-openssl to enable OpenSSL library support.

--with-coss-membuf-size

The COSS cache type has been removed. It has been replaced by rock cache type.

--with-krb5-config

Removed. The Kerberos library is auto-detected now.

Use --with/--without-mit-krb5, --with/--without-heimdal-krb5, or --with/--without-gnugss options for specific library selection if necesary.

5. Regressions since Squid-2.7

Some squid.conf options which were available in Squid-2.7 are not yet available in Squid-3.5

This flag disables the optimization. The default is to auto-detect compiler support and use where available. --disable-strict-error-checking By default squid is compiled with all possible static compiler error-checks enabled. This flag disables the behavior --disable-loadable-modules do not support loadable modules --enable-shared[=PKGS] build shared libraries [default=yes] --enable-static[=PKGS] build static libraries [default=yes] --enable-fast-install[=PKGS] optimize for fast installation [default=yes] --disable-libtool-lock avoid locking (might break parallel builds) --enable-ltdl-install install libltdl --enable-build-info="build info string" Add an additional string in the output of "squid -v". Default is not to add anything. If the string is not specified, tries to determine nick and revision number of the current bazaar branch --disable-optimizations Do not compile Squid with compiler optimizations enabled. Optimization is good for production builds, but not good for debugging. During development, use --disable-optimizations to reduce compilation times and allow easier debugging. This option implies --disable-inline --disable-inline Do not compile trivial methods as inline. Squid is coded with much of the code able to be inlined. Inlining is good for production builds, but not good for development. During development, use --disable-inline to reduce compilation times and allow incremental builds to be quick. For production builds, or load tests, use --enable-inline to have squid make all trivial methods inlinable by the compiler. --enable-debug-cbdata Provide some debug information in cbdata --enable-xmalloc-statistics Show malloc statistics in status page --enable-disk-io="list of modules" Build support for the list of disk I/O modules. Set without a value or omitted, all available modules will be built.

Enabling this alone does nothing; you also have to modify the source code to use the leak finding functions. Probably Useful for hackers only. --enable-follow-x-forwarded-for Enable support for following the X-Forwarded-For HTTP header to try to find the IP address of the original or indirect client when a request has been forwarded through other proxies. --disable-ident-lookups Remove code that supports performing Ident (RFC 931) lookups. --enable-ssl-crtd Prevent Squid from directly generation of SSL private key and certificate request and instead enables the ssl_crtd processes. --enable-default-hostsfile=path Select default location for hosts file. See hosts_file directive in squid.conf for details --enable-auth Build global support for authentication. The list of schemes and helpers to be enabled is defined elsewhere --enable-auth-basic="list of helpers" Enable the basic authentication scheme, and build the specified helpers. Not providing an explicit list of helpers will attempt build of all possible helpers. Default is to do so. To disable the basic authentication scheme, use --disable-auth-basic. To enable but build no helpers, specify "none". To see available helpers, see the helpers/basic_auth directory. --enable-auth-digest="list of helpers" Enable the Digest authentication scheme, and build the specified helpers. Not providing an explicit list of helpers will attempt build of all possible helpers. Default is to do so. To disable the Digest authentication scheme, use --disable-auth-digest. To enable but build no helpers, specify "none". To see available helpers, see the helpers/digest_auth directory. --enable-auth-negotiate="list of helpers" Enable the Negotiate authentication scheme, and build the specified helpers. Not providing an explicit list of helpers will attempt build of all possible helpers. Default is to do so. To disable the Negotiate authentication scheme, use --disable-auth-negotiate. To enable but build no helpers, specify "none". To see available helpers, see the helpers/negotiate_auth directory. --enable-auth-ntlm="list of helpers" Enable the NTLM authentication scheme, and build the specified helpers. Not providing an explicit list of helpers will attempt build of all possible helpers. Default is to do so. To disable the NTLM authentication scheme, use --disable-auth-ntlm. To enable but build no helpers, specify "none". To see available helpers, see the helpers/ntlm_auth directory. --enable-log-daemon-helpers="list of helpers" This option selects which logging daemon helpers to build and install as part of the normal build process For a list of available helpers see the helpers/log_daemon directory. --enable-external-acl-helpers="list of helpers" Enable external_acl helpers support and thelpers themselves. Default is to build all buildable helpers and enable support. To disable support, use --disable-external-acl-helpers. To build no helpers, specify "none". To see available helpers, see the helpers/external_acl directory --enable-url-rewrite-helpers="list of helpers" This option selects which url_rewrite helpers to build and install as part of the normal build process. The default is to attempt the build of all possible helpers. Use --disable-url-rewrite-helpers to build none. For a list of available helpers see the helpers/url_rewrite directory. --enable-storeid-rewrite-helpers="list of helpers" This option selects which Store-ID rewrite helpers to build and install as part of the normal build process. The default is to attempt the build of all possible helpers. Use --disable-storeid-rewrite-helpers to build none. For a list of available helpers see the helpers/storeid_rewrite directory. --enable-win32-service Compile Squid as a WIN32 Service. Works only on MS-Windows platforms --disable-unlinkd Do not use unlinkd --enable-stacktraces Enable automatic call backtrace on fatal errors --enable-cpu-profiling Enable instrumentation to try and understand how CPU power is spent by squid, by enabling specific probes in selected functions. New probes can only be added by modifying the source code. It is meant to help developers in optimizing performance of Squid internal functions. If you are not developer you should not enable this, as it slows squid down somewhat. See lib/Profiler.c for more details. --enable-x-accelerator-vary Enable support for the X-Accelerator-Vary HTTP header. Can be used to indicate variance within an accelerator setup. Typically used together with other code that adds custom HTTP headers to the requests. --disable-ipv6 Disable IPv6 support. The default is to probe system capabilities on startup. --enable-zph-qos Enable ZPH QOS support --enable-gnuregex Compile GNUregex. Unless you have reason to use this option, you should not enable it. This library file is usually only required on Windows and very old Unix boxes which do not have their own regex library built in. --enable-translation Generate the localized error page templates and manuals. Which can also be downloaded from http://www.squid-cache.org/Versions/langpack/. --disable-auto-locale This prevents Squid providing localized error pages based on the clients request headers. When disabled Squid requires explicit language configuration.

1. Notice

The Squid Team are pleased to announce the release of Squid-3.5.12.

This new release is available for download from http://www.squid-cache.org/Versions/v3/3.5/ or the mirrors.

Some interesting new features adding system flexibility have been added along with general improvements all around. While this release is not fully bug-free we believe it is ready for use in production on many systems.

We welcome feedback and bug reports. If you find a bug, please see http://wiki.squid-cache.org/SquidFaq/BugReporting for how to submit a report with a stack trace.

1.1 Known issues

Although this release is deemed good enough for use in many setups, please note the existence of open bugs against Squid-3.5.

1.2 Changes since earlier releases of Squid-3.5

The 3.5 change history can be viewed here.

1.3 Copyright disclaimer adjustments

Squid sources are now administered by the Squid Software Foundation on behalf of the Squid Project and community.

This version of Squid contains initial changes to streamline copyright declarations in Squid sources and related metafiles. No functionality or licensing changes are intended.

Once completed, the changes will consistently declare Squid contributors (listed in CONTRIBUTORS and represented by the Squid Software Foundation) as Squid copyright owners while referring the reader to the COPYING file for GPL licensing details. The boilerplate with the above information is provided.

These changes do not affect copyright rights of individuals or organizations. We are simply confirming the fact that there are many Squid copyright owners, just like there are many Linux kernel copyright owners. We are also providing a simple, consistent way to document that fact.

2. Major new features since Squid-3.4

Squid 3.5 represents a new feature release above 3.4.

The most important of these new features are:

  • Support libecap v1.0
  • Authentication helper query extensions
  • Support named services
  • Upgraded squidclient tool
  • Helper support for concurrency channels
  • Native FTP Relay
  • Receive PROXY protocol, Versions 1 & 2
  • Basic authentication MSNT helper changes

Most user-facing changes are reflected in squid.conf (see below).

2.1 Support libecap v1.0

Details at http://wiki.squid-cache.org/Features/eCAP.

The new libecap version allows Squid to better check the version of the eCAP adapter being loaded as well as the version of the eCAP library being used.

Squid-3.5 can support eCAP adapters built with libecap v1.0, but no longer supports adapters built with earlier libecap versions due to API changes.

2.2 Authentication helper query extensions

Details at http://www.squid-cache.org/Doc/config/auth_param/.

The new key_extras parameter allows sending of additional details to the authentication helper beyond the minimum required for the HTTP authentication. This is primarily intended to allow switching of authentication databases based on criteria such as client IP subnet, Squid receiving port, or in reverse-proxy the requested domain name.

In theory any logformat code may be used, however only the codes which have available details at the time of authentication will send any meaningful detail.

2.3 Support named services

Details at http://wiki.squid-cache.org/MultipleInstances.

Terminology details at http://wiki.squid-cache.org/Features/SmpScale#Terminology.

The command line option -n assigns a name to the Squid service instance to be used as a unique identifier for all SMP processes run as part of that instance. This allows multiple instances of Squid service to be run on a single machine without background SMP systems such as shared memory and inter-process communication becoming confused or requiring additional configuration.

A service name is always used. When the -n option is missing from the command line the default service name is squid.

When multiple instances are being run the -n service name is required to target all other options such as -z or -k commands at the correct service.

The squid.conf macro ${service_name} is added to provide the service name of the process parsing the config.

2.4 Upgraded squidclient tool

Details at http://www.squid-cache.org/Versions/v3/3.5/manuals/squidclient.html.

The squidclient has begun the process of upgrading to support protocols other than HTTP.

Debug levels

The tool displays the server response message on STDOUT unless the -q command line option is used. Error messages will be output to STDERR. All other possible output is considered debug and output to STDERR using a range of debug verbosity levels (currently 1, 2 and 3).

When the -v command line option is used debugging is enabled. The level of debug display is raised for each repetition of the option.

PING

When --ping is given the tool will send its message repeatedly using whichever protocol that message has been formatted for. Optional parameters to limit the number of pings and their frequency are available.

Older tool versions also provide this feature but require the loop count parameter to be set to enable use of the feature.

HTTPS

When Squid is built with the GnuTLS encryption library the tool is able to open TLS (or SSL/3.0) connections to servers.

The --https option enables TLS using default values.

The --cert option specifies a file containing X.509 client certificate and private key in PEM format to be loaded for use. Multiple certificates are supported and the option may be used multiple times to load certificates. The default is not to use a client certificate.

The --params option specifies a library specific set of parameters to be sent to the library for configuring the security context. See http://gnutls.org/manual/html_node/Priority-Strings.html for available GnuTLS parameters.

The --trusted-ca option specifies a file in PEM format containing one or more Certificate Authority (CA) certificates used to verify the remote server. This option may be used multiple times to load additional CA certificate lists. The default is not to use any CA, nor trust any server.

Anonymous TLS (using non-authenticated Diffi-Hellman or Elliptic Curve encryption) is available with the --anonymous-tls option. The default is to use X.509 certificate encryption instead.

When performing TLS/SSL server certificates are always verified, the results shown at debug level 3. The encrypted type is displayed at debug level 2 and the connection is used to send and receive the messages regardless of verification results.

2.5 Helper support for concurrency channels

Helper concurrency greatly reduces the communication lag between Squid and its helpers allowing faster transaction speeds even on sequential helpers.

The Digest authentication, Store-ID, and URL-rewrite helpers packaged with Squid have been updated to support concurrency channels. They will auto-detect the channel-ID field and will produce the appropriate response format. With these helpers concurrency may now be set to 0 or any higher number as desired.

2.6 Native FTP Relay

Details at http://wiki.squid-cache.org/Features/FtpRelay.

Squid is now capable of accepting native FTP commands and relaying native FTP messages between FTP clients and FTP servers. Native FTP commands accepted at ftp_port are internally converted or wrapped into HTTP-like messages. The same happens to Native FTP responses received from FTP origin servers. Those HTTP-like messages are shoveled through regular access control and adaptation layers between the FTP client and the FTP origin server. This allows Squid to examine, adapt, block, and log FTP exchanges. Squid reuses most HTTP mechanisms when shoveling wrapped FTP messages. For example, http_access and adaptation_access directives are used.

FTP Relay is a new, experimental, complex feature that has seen limited production exposure. Some Squid modules (e.g., caching) do not currently work with native FTP proxying, and many features have not even been tested for compatibility. Test well before deploying!

Native FTP proxying differs substantially from proxying HTTP requests with ftp:// URIs because Squid works as an FTP server and receives actual FTP commands (rather than HTTP requests with FTP URLs).

FTP Relay highlights:

  • Added ftp_port directive telling Squid to relay native FTP commands.
  • Active and passive FTP support on the user-facing side; require passive connections to come from the control connection source IP address.
  • IPv6 support (EPSV and, on the user-facing side, EPRT).
  • Intelligent adaptation of relayed FTP FEAT responses.
  • Relaying of multi-line FTP control responses using various formats.
  • Support relaying of FTP MLSD and MLST commands (RFC 3659).
  • Several Microsoft FTP server compatibility features.
  • ICAP/eCAP support (at individual FTP command/response level).
  • Optional "current FTP directory" tracking with the assistance of injected (by Squid) PWD commands (cannot be 100% reliable due to symbolic links and such, but is helpful in some common use cases).
  • No caching support -- no reliable Request URIs for that (see above).

2.7 Receive PROXY protocol, Versions 1 & 2

More info at http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt

PROXY protocol provides a simple way for proxies and tunnels of any kind to relay the original client source details without having to alter or understand the protocol being relayed on the connection.

Squid currently supports receiving HTTP traffic from a client proxy using this protocol. An http_port which has been configured to receive this protocol may only be used to receive traffic from client software sending in this protocol. HTTP traffic without the PROXY header is not accepted on such a port.

The accel and intercept options are still used to identify the HTTP traffic syntax being delivered by the client proxy.

Squid can be configured by adding an http_port with the require-proxy-header mode flag. The proxy_protocol_access must also be configured with src ACLs to whitelist proxies which are trusted to send correct client details.

Forward-proxy traffic from a client proxy: 

 acl frontend src 192.0.2.1
 http_port 3128 require-proxy-header
 proxy_protocol_access allow frontend

Intercepted traffic from a client proxy or tunnel: 

 acl frontend src 192.0.2.2
 http_port 3128 intercept require-proxy-header
 proxy_protocol_access allow frontend

Reverse-proxy traffic from a frontend load balancer sending PROXY protocol: 

 acl frontend src 192.0.2.3
 http_port 3128 accel require-proxy-header
 proxy_protocol_access allow frontend

Known Issue: Use of require-proxy-header on https_port and ftp_port is not supported.

2.8 Basic authentication MSNT helper changes

The authentication helper previously known as basic_msnt_auth has been deprecated and renamed to basic_smb_lm_auth to reflect that it only performs SMB LanMan protocol(s) instead of modern MS authentication protocols.

The basic_smb_lm_auth helper has been remodelled and no longer uses configuration files. The Doman Controller servers are now configured via command line parameters and user credentials are looked up in each DC in the order configured until one matches or all have confirmed a non-match.

The MSNT-multi-domain helper provides the same functionality and is also deprecated. It will be removed in the Squid-3.6 series.

3. Changes to squid.conf since Squid-3.4

There have been changes to Squid's configuration file since Squid-3.4.

Squid supports reading configuration option parameters from external files using the syntax parameters("/path/filename"). For example: 

    acl whitelist dstdomain parameters("/etc/squid/whitelist.txt")

The squid.conf macro ${service_name} is added to provide the service name of the process parsing the config.

There have also been changes to individual directives in the config file.

This section gives a thorough account of those changes in three categories:

3.1 New tags

collapsed_forwarding

Ported from Squid-2 with no configuration or visible behaviour changes. Collapsing of requests is performed across SMP workers.

ftp_client_idle_timeout

New directive controlling how long to wait for an FTP request on a client connection to Squid ftp_port.

Many FTP clients do not deal with idle connection closures well, necessitating a longer default timeout (30 minutes) than client_idle_pconn_timeout used for incoming HTTP requests (2 minutes).

The current default may be changed as we get more experience with FTP relaying.

ftp_port

New configuration directive to accept and relay native FTP commands. Typically used for port 21 traffic. By default, native FTP commands are not accepted.

proxy_protocol_access

New directive to control which clients are permitted to open PROXY protocol connections on a port flagged with require-proxy-header.

send_hit

New configuration directive to enable/disable sending cached content based on ACL selection. ACL can be based on client request or cached response details.

sslproxy_cert_sign_hash

New directive to set the hashing algorithm to use when signing generated certificates.

sslproxy_session_cache_size

New directive which sets the cache size to use for TLS/SSL sessions cache.

sslproxy_session_ttl

New directive to specify the time in seconds the TLS/SSL session is valid.

store_id_extras

New directive to send additional lookup parameters to the configured Store-ID helper program. It takes a string which may contain logformat %macros.

The Store-ID helper input format is now: 

         [channel-ID] url [extras]

The default value for extras is: "%>a/%>A %un %>rm myip=%la myport=%lp"

store_miss

New configuration directive to enable/disable caching of MISS responses. ACL can be based on any request or response details.

url_rewrite_extras

New directive to send additional lookup parameters to the configured URL-rewriter/redirector helper program. It takes a string which may contain logformat %macros.

The url rewrite and redirector helper input format is now: 

         [channel-ID] url [extras]

The default value for extras is: "%>a/%>A %un %>rm myip=%la myport=%lp"

3.2 Changes to existing tags

acl

Deprecated type tag. Use type note with 'tag' key name instead.

New type adaptation_service to match the name of any icap_service, ecap_service, adaptation_service_set, or adaptation_service_chain that Squid has used (or attempted to use) for the HTTP transaction so far.

New type at_step to match the current SSL-Bump processing step. Never matches and should not be used outside of ssl_bump.

New types ssl::server_name and ssl::server_name_regex to match server name from various sources (CONNECT authority name, TLS SNI domain, or X.509 certificate Subject Name).

auth_param

New parameter key_extras to send additional parameters to the authentication helper.

cache_dir

New support for larger than 32KB objects in both rock type cache and shared memory cache.

New slot-size=N option for rock cache to specify the database slot/page size when small slot sizes are desired. The default and maximum slot size is 32KB.

Removal of old rock cache dir followed by squid -z is required when upgrading from earlier versions of Squid.

COSS storage type is formally replaced by Rock storage type. COSS storage type and all COSS specific options are removed.

cache_peer

New standby=N option to retain a set of N open and unused connections to the peer at virtually all times to reduce TCP handshake delays.

These connections differ from HTTP persistent connections in that they have not been used for HTTP messaging (and may never be). They may be turned into persistent connections after their first use subject to the same keep-alive critera any HTTP connection is checked for.

Squid-2 option idle= replaced by standby=.

NOTE that standby connections are started earlier and available in more circumstances than squid-2 idle connections were. They are also spread over all IPs of the peer.

configuration_includes_quoted_values

Regex pattern values cannot be parsed in parts of squid.conf when this directive is configured to ON. Instead of quoted strings Squid now accepts regex \-escaped characters (including escaped spaces) in all regex patterns.

external_acl_type

New format code %ssl::>sni to send SSL client SNI.

New format code %ssl::<cert_subject to send SSL server certificate DN.

New format code %ssl::<cert_issuer to send SSL server certificate issuer DN.

New format code %un to send any available user name (requires 3.5.7 or later).

New response kv-pair clt_conn_tag= to associates a given tag with the client TCP connection.

forward_max_tries

Default value increased to 25 destinations to allow better contact and IPv4 failover with domains using long lists of IPv6 addresses.

ftp_epsv

Converted into an Access List with allow/deny value driven by ACLs using Squid standard first line wins matching basis.

The old values of on and off imply allow all and deny all respectively and are now deprecated. Do not combine use of on/off values with ACL configuration.

http_port

protocol= option altered to accept protocol version details. Currently supported values are: HTTP, HTTP/1.1, HTTPS, HTTPS/1.1

New option require-proxy-header to mark ports receiving PROXY protocol version 1 or 2 traffic.

https_port

protocol= option altered to accept protocol version details. Currently supported values are: HTTP, HTTP/1.1, HTTPS, HTTPS/1.1

logformat

New format code %credentials to log the client credentials token.

New format code %ssl::>sni to TLS client SNI sent to Squid.

New format code %tS to log transaction start time in "seconds.milliseconds" format, similar to the existing access.log "current time" field (%ts.%03tu) which logs the corresponding transaction finish time.

New format codes %<rs and %>rs to log request URL scheme from client or sent to server/peer respectively.

New format codes %<rd and %>rd to log request URL domain from client or sent to server/peer respectively.

New format codes %<rP and %>rP to log request URL port from client or sent to server/peer respectively.

ssl_bump

Bumping 'modes' redesigned as 'actions' and ACLs evaluated repeatedly in a number of steps.

Renamed server-first as bump action.

Renamed none as splice action.

New actions peek and stare to receive client or server certificate while preserving the ability to later decide between bumping or splicing the connections later.

New action terminate to close the client and server connections.

url_rewrite_program

New response kv-pair clt_conn_tag= to associates a given tag with the client TCP connection.

3.3 Removed tags

cache_dns_program

DNS external helper interface has been removed. It was no longer able to provide high performance service and the internal DNS client library with multicast DNS cover all modern use-cases.

dns_children

DNS external helper interface has been removed.

hierarchy_stoplist

Removed. The old directive values prohibiting CGI and dynamic content going to cache_peer are no longer relevant.

The functionality provided by this directive can be configured using always_direct allow if still needed.

4. Changes to ./configure options since Squid-3.4

There have been some changes to Squid's build configuration since Squid-3.4.

This section gives an account of those changes in three categories:

4.1 New options

BUILDCXX=

Used when cross-compiling Squid.

The path and name of a compiler for building cf_gen and related tools used in the compile process.

BUILDCXXFLAGS=

Used when cross-compiling Squid.

C++ compiler flags used for building cf_gen and related tools used in the compile process.

--without-gnutls

New option to explicitly disable use of GnuTLS encryption library. Use of this library is auto-enabled if v3.1.5 or later is available.

It is currently only used by the squidclient tool.

--without-mit-krb5

New option to explicitly disable use of MIT Kerberos library. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

--without-heimdal-krb5

New option to explicitly disable use of Hiemdal Kerberos library. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

--without-gnugss

New option to explicitly disable use of GNU GSSAPI library for Kerberos. Default is to auto-detect and use if possible.

Only one Kerberos library may be built against.

4.2 Changes to existing options

--enable-icap-client

Deprecated. ICAP client is now auto-enabled. Use --disable-icap-client to disable if you need to.

4.3 Removed options

--disable-internal-dns

DNS external helper interface has been removed. It was no longer able to provide high performance service and the internal DNS client library with multicast DNS cover all modern use-cases.

--enable-ssl

Removed. Use --with-openssl to enable OpenSSL library support.

--with-coss-membuf-size

The COSS cache type has been removed. It has been replaced by rock cache type.

--with-krb5-config

Removed. The Kerberos library is auto-detected now.

Use --with/--without-mit-krb5, --with/--without-heimdal-krb5, or --with/--without-gnugss options for specific library selection if necesary.

5. Regressions since Squid-2.7

Some squid.conf options which were available in Squid-2.7 are not yet available in Squid-3.5

If you need something to do then porting one of these from Squid-2 to Squid-3 is most welcome.

URI Host Conflict

This means the domain name you are trying to access apparently no longer exists on the machine you are requesting it from.

Some possible problems are:

  • The domain may have moved very recently. Trying again will resolve that.
  • The website may require you to use a local country-based version. Using your ISP provided DNS server(s) should resolve that.

This means the domain name you are trying to access apparently no longer exists on the machine you are requesting it from.

Some possible problems are:

  • The domain may have moved very recently. Trying again will resolve that.
  • The website may require you to use a local country-based version. Using your ISP provided DNS server(s) should resolve that.

This means the domain name you are trying to access apparently no longer exists on the machine you are requesting it from.

Some possible problems are:

  • The domain may have moved very recently. Trying again will resolve that.

URI Host Conflict

This means the domain name you are trying to access apparently no longer exists on the machine you are requesting it from.

Några möjliga problem är:

LDAP options are specified as parameters on the command line, while the username(s) and password(s) to be checked against the LDAP directory are specified on subsequent lines of input to the helper, one username/password pair per line separated by a space. .PP As expected by the basic authentication construct of Squid, after specifying a username and password followed by a new line, this helper will produce either .B OK or .B ERR on the following line to show if the specified credentials are correct according to the LDAP directory. .PP The program has two major modes of operation. In the default mode of operation the users DN is constructed using the base DN and user attribute. In the other mode of operation a search filter is used to locate valid user DN's below the base DN. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B "\-b basedn" .B REQUIRED. Specifies the base DN under which the users are located. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-f filter" LDAP search .B filter to locate the user DN. Required if the users are in a hierarchy below the base DN, or if the login name is not what builds the user specific part of the users DN. .br The search filter can contain up to 15 occurrences of .B %s which will be replaced by the username, as in .B "\"uid\=%s\"" for RFC2037 directories. For a detailed description of LDAP search filter syntax see RFC2254. .br Will crash if other .B % values than .B %s are used, or if more than 15 .B %s are used. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-u userattr" Specifies the name of the DN attribute that contains the username/login. Combined with the base DN to construct the users DN when no search filter is specified ( .B \-f option). Defaults to .B uid .br .B Note: This can only be done if all your users are located directly under the same position in the LDAP tree and the login name is used for naming each user object. If your LDAP tree does not match these criterias or if you want to filter who are valid users then you need to use a search filter to search for your users DN ( .B \-f option). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-U passwordattr" Use .I ldap_compare instead of .I ldap_simple_bind to verify the users password. .B passwordattr is the LDAP attribute storing the users password. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-s base|one|sub" Search scope when performing user DN searches specified by the .B \-f option. Defaults to .B sub .br .IP .B base object only, .IP .B one level below the base object or .IP .BR sub tree below the base object . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-D binddn \-w password" The DN and password to bind as while performing searches. Required by the .B \-f flag if the directory does not allow anonymous searches. .br As the password needs to be printed in plain text in your Squid configuration it is strongly recommended to use a account with minimal associated privileges. This to limit the damage in case someone could get hold of a copy of your Squid configuration file. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-D binddn \-W secretfile " The DN and the name of a file containing the password to bind as while performing searches. .br Less insecure version of the former parameter pair with two advantages: The password does not occur in the process listing, and the password is not being compromised if someone gets the squid configuration file without getting the secretfile. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-P Use a persistent LDAP connection. Normally the LDAP connection is only open while validating a username to preserve resources at the LDAP server. This option causes the LDAP connection to be kept open, allowing it to be reused for further user validations. Recommended for larger installations. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-O Only bind once per LDAP connection. Some LDAP servers do not allow re-binding as another user after a successful .I ldap_bind. The use of this option always opens a new connection for each login attempt. If combined with the .B \-P option for persistent LDAP connection then the connection used for searching for the user DN is kept persistent but a new connection is opened to verify each users password once the DN is found. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-R Do not follow referrals . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-a never|always|search|find" when to dereference aliases. Defaults to .B never .IP .B never dereference aliases (default), .B always dereference aliases, only while .B search ing or only to .B find the base object. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-H ldap_uri Specity the LDAP server to connect to by LDAP URI (requires OpenLDAP libraries). Servers can also be specified last on the command line. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-h ldap_server" Specify the LDAP server to connect to. Servers can also be specified last on the command line. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-p ldap_port" Specify an alternate TCP port where the LDAP server is listening if other than the default LDAP port 389. Can also be specified within the server specification by using servername:port syntax. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-v 2|3" LDAP protocol version. Defaults to .B 3 if not specified. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-Z Use TLS encryption . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-S certpath" Enable LDAP over SSL (requires Netscape LDAP API libraries) . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-c connect_timeout" Specify .B timeout used when connecting to LDAP servers (requires Netscape LDAP API libraries) . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-t search_timeout" Specify time limit on LDAP search operations . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-d Debug mode where each step taken will get reported in detail. Useful for understanding what goes wrong if the results is not what is expected. . .SH CONFIGURATION For directories using the RFC2307 layout with a single domain, all you need to specify is usually the base DN under where your users are located and the server name: .IP .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ldap_auth -b "ou=people,dc=your,dc=domain" ldapserver .if !'po4a'hide' .RE .PP If you have sub\-domains then you need to use a search filter approach to locate your user DNs as these can no longer be constructed directly from the base DN and login name alone: .IP .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ldap_auth -b "dc=your,dc=domain" -f "uid=%s" ldapserver .if !'po4a'hide' .RE .PP And similarly if you only want to allow access to users having a specific attribute .IP .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ldap_auth -b "dc=your,dc=domain" -f "(&(uid=%s)(specialattribute=value))" ldapserver .if !'po4a'hide' .RE .PP Or if the user attribute of the user DN is .B "cn" instead of .B "uid" and you do not want to have to search for the users then you could use something like the following example for Active Directory: .IP .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ldap_auth -u cn -b "cn=Users,dc=your,dc=domain" ldapserver .if !'po4a'hide' .RE .PP If you want to search for the user DN and your directory does not allow anonymous searches then you must also use the .B \-D and .B \-w flags to specify a user DN and password to log in as to perform the searches, as in the following complex Active Directory example .IP .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ldap_auth -P -R -b "dc=your,dc=domain" -D "cn=squid,cn=users,dc=your,dc=domain" -w "secretsquidpassword" -f "(&(userPrincipalName=%s)(objectClass=Person))" activedirectoryserver .if !'po4a'hide' .RE . .PP .B NOTE: When constructing search filters it is strongly recommended to test the filter using .B ldapsearch before you attempt to use .B basic_ldap_auth. This to verify that the filter matches what you expect. . .SH AUTHOR This program is written by .if !'po4a'hide' .I Glenn Newton .if !'po4a'hide' .I Henrik Nordstrom .

Persistent connections moved to -P * 2001-05-02: Henrik Nordstrom * - Support newer OpenLDAP 2.x libraries using the * revised Internet Draft API which unfortunately * is not backwards compatible with RFC1823.. * 2001-04-15: Henrik Nordstrom * - Added command line option for basedn * - Added the ability to search for the user DN * 2001-04-16: Henrik Nordstrom * - Added -D binddn -w bindpasswd. * 2001-04-17: Henrik Nordstrom * - Added -R to disable referrals * - Added -a to control alias dereferencing * 2001-04-17: Henrik Nordstrom * - Added -u, DN username attribute name * 2001-04-18: Henrik Nordstrom * - Allow full filter specifications in -f */ #include "squid.h" #define LDAP_DEPRECATED 1 #include "rfc1738.h" #include "util.h" #include #include #if _SQUID_WINDOWS_ && !_SQUID_CYGWIN_ #define snprintf _snprintf #include #include #ifndef LDAPAPI #define LDAPAPI __cdecl #endif #ifdef LDAP_VERSION3 #ifndef LDAP_OPT_X_TLS #define LDAP_OPT_X_TLS 0x6000 #endif /* Some tricks to allow dynamic bind with ldap_start_tls_s entry point at * run time. */ #undef ldap_start_tls_s #if LDAP_UNICODE #define LDAP_START_TLS_S "ldap_start_tls_sW" typedef WINLDAPAPI ULONG(LDAPAPI * PFldap_start_tls_s) (IN PLDAP, OUT PULONG, OUT LDAPMessage **, IN PLDAPControlW *, IN PLDAPControlW *); #else #define LDAP_START_TLS_S "ldap_start_tls_sA" typedef WINLDAPAPI ULONG(LDAPAPI * PFldap_start_tls_s) (IN PLDAP, OUT PULONG, OUT LDAPMessage **, IN PLDAPControlA *, IN PLDAPControlA *); #endif /* LDAP_UNICODE */ PFldap_start_tls_s Win32_ldap_start_tls_s; #define ldap_start_tls_s(l,s,c) Win32_ldap_start_tls_s(l,NULL,NULL,s,c) #endif /* LDAP_VERSION3 */ #else #include #include #endif #define PROGRAM_NAME "basic_ldap_auth" /* Global options */ static const char *basedn; static const char *searchfilter = NULL; static const char *binddn = NULL; static const char *bindpasswd = NULL; static const char *userattr = "uid"; static const char *passwdattr = NULL; static int searchscope = LDAP_SCOPE_SUBTREE; static int persistent = 0; static int bind_once = 0; static int noreferrals = 0; static int aliasderef = LDAP_DEREF_NEVER; #if defined(NETSCAPE_SSL) static const char *sslpath = NULL; static int sslinit = 0; #endif static int connect_timeout = 0; static int timelimit = LDAP_NO_LIMIT; /* Added for TLS support and version 3 */ static int use_tls = 0; static int version = -1; static int checkLDAP(LDAP * ld, const char *userid, const char *password, const char *server, int port); static int readSecret(const char *filename); /* Yuck.. we need to glue to different versions of the API */ #ifndef LDAP_NO_ATTRS #define LDAP_NO_ATTRS "1.1" #endif #if defined(LDAP_API_VERSION) && LDAP_API_VERSION > 1823 static int squid_ldap_errno(LDAP * ld) { int err = 0; ldap_get_option(ld, LDAP_OPT_ERROR_NUMBER, &err); return err; } static void squid_ldap_set_aliasderef(LDAP * ld, int deref) { ldap_set_option(ld, LDAP_OPT_DEREF, &deref); } static void squid_ldap_set_referrals(LDAP * ld, int referrals) { int *value = static_cast(referrals ?

NOTE: Blowfish and SHA algorithms require system-specific support. . .SH OPTIONS The only parameter is the password file. It must have permissions to be read by the user that Squid is running as. . .SH CONFIGURATION .if !'po4a'hide' .RS .if !'po4a'hide' .B basic_ncsa_auth /etc/squid/squid.pass .if !'po4a'hide' .RE .PP .B basic_ncsa_auth must have access to the password file to be executed. . .SH KNOWN ISSUES .PP DES functionality (used by htpasswd by default) silently truncates passwords to 8 characters. Allowing login with password values shorter than the one desired. This authenticator will reject login with long passwords when using DES. . .SH AUTHOR This manual was written by .if !'po4a'hide' .I Amos Jeffries .PP Based on original documentation by .if !'po4a'hide' .I Rodrigo Rubira Branco . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This file is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The TTL specifies how long the connection will be kept open (in seconds). Default is to not keep PAM connections open. Please note that the use of persistent PAM connections is slightly outside the PAM specification and may not work with all PAM configurations. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-o Do not perform the PAM account management group (account expiration etc) . .SH CONFIGURATION The program needs a PAM service to be configured in .BR /etc/pam.conf or .BR /etc/pam.d/squid .PP The default service name is .B squid , and the program makes use of the .B auth and .B account management groups to verify the password and the accounts validity. .PP For details on how to configure PAM services, see the PAM documentation for your system. This manual does not cover PAM configuration details. . .SH NOTES . When used for authenticating to local UNIX shadow password databases the program must be running as root or else it won't have sufficient permissions to access the user password database. Such use of this program is not recommended, but if you absolutely need to then make the program setuid root .if !'po4a'hide' .RS .if !'po4a'hide' .P .if !'po4a'hide' .B chown root basic_pam_auth .if !'po4a'hide' .br .if !'po4a'hide' .B chmod u+s basic_pam_auth .if !'po4a'hide' .RE .PP Please note that in such configurations it is also strongly recommended that the program is moved into a directory where normal users cannot access it, as this mode of operation will allow any local user to brute-force other users passwords. Also note the program has not been fully audited and the author cannot be held responsible for any security issues due to such installations. . .SH AUTHOR This program and documentation was written by .if !'po4a'hide' .I Henrik Nordstrom . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP Squid .B basic_pam_auth and this manual is Copyright 1999,2002,2003 .if !'po4a'hide' .I Henrik Nordstrom .

See COPYRIGHT for details. This authenticator is specifically made for Squid-2.5 and later. Installation: Copy the correct makefile to Makefile Makefile.default = Most OS:es. Makefile.solaris = SunOS5 (Solaris) cp Makefile.default Makefile make clean make install or if you want the helper installed elsewhere than /usr/local/squid (the default installation path of Squid) use something like: make CONFDIR=/etc PREFIX=/usr BINDIR='${PREFIX}/libexec/squid' install Complete list of make options for tweakin the installation paths: PREFIX Top level installation directory (/usr/local/squid) BINDIR Where the binary is installed (PREFIX/libexec) CONFDIR Where the configuration file is installed (PREFIX/etc) MANDIR Where the manpage is installed (PREFIX/man/man8) MANEXT Manpage extension (.8) DESTDIR Root prefix for packaging Configuration: The RADIUS authenticator is configured using a small configuration file. The configuration file should look like this: # basic_radius_auth configuration file # MvS: 28-10-1998 server suncone.cistron.nl secret testje An example can be found in etc/basic_radius_auth.conf /etc/services: Modify /etc/services and add: radius 1812/udp Adding this is not mandatory because it used the default port 1812 anyway. Note: Some old RADIUS servers uses the unofficial port 1645, and you may need to override the service port used either by editing /etc/services or by specifying the port using the -p command line option or the port tag in basic_radius_auth.conf Test it: Start basic_radius_auth and type a username and a username. The authenticator returns OK if the radiusd accepted your password. In any other case you'll get ERR. Squid: Add the authenticator to squid.conf. See the instructions from squid for help.

See the CONFIGURATION section for details on the file content. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-h server" Alternative method of specifying the server to connect to . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-p port" Specify another server port where the RADIUS server listens for requests if different from the default RADIUS port. Normally not specified. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-i identifier" Unique identifier identifying this Squid proxy to the RADIUS server. If not specified the IP address is used to identify the proxy. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-w secret" Alternative method of specifying the shared secret. Using the .B \-f option with a configuration file is generally more secure and recommended. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-t timeout" RADIUS request timeout. Default is 10 seconds. . .SH CONFIGURATION The configuration specifies how the helper connects to RADIUS. The file contains a list of directives (one per line).

SASL is configurable (somewhat like PAM). Each service authenticating against SASL identifies itself with an application name. Each application can be configured independently by the SASL administrator. . .SH CONFIGURATION To configure the authentication method used the file .B basic_sasl_auth.conf can be placed in the appropriate location, usually .B /usr/lib/sasl. .PP The authentication database is defined by the .B pwcheck_method parameter. Only the .B PLAIN authentication mechanism is used. .PP Examples: . .if !'po4a'hide' .B pwcheck_method:sasldb use sasldb - the default if no conf file is installed. .if !'po4a'hide' .B pwcheck_method:pam - use PAM authentication database .if !'po4a'hide' .B pwcheck_method:passwd - use traditional .B /etc/passwd .if !'po4a'hide' .B pwcheck_method:shadow - use slightly less traditional /etc/shadow .PP Others methods may be supported by your cyrus-sasl implementation - consult your cyrus-sasl documentation for information. .PP Typically the authentication database ( .B /etc/sasldb , .B /etc/shadow , .B PAM ) can not be accessed by a normal user. You should use setuid/setgid and an appropriate user/group on the executable to allow the authenticator to access the appropriate password database. If the access to the database is not permitted then the authenticator will typically fail with "-1, generic error". .PP .if !'po4a'hide' .RS .if !'po4a'hide' .P .if !'po4a'hide' .B chown root.mail basic_sasl_auth .if !'po4a'hide' .br .if !'po4a'hide' .B chmod ug+s basic_sasl_auth .if !'po4a'hide' .RE .PP If the application name .B basic_sasl_auth will also be used for the PAM service name if .B pwcheck_method:pam is chosen. And example PAM configuration file .B basic_sasl_auth.pam is also included. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Ian Castle .PP This manual was written by .if !'po4a'hide' .I Ian Castle .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

Reported by Menno Stevens. - The -S option now accepts both slashes and backslashes and allows the share name to be preceded by a (back)slash. 5 June 1999, version 0.04 - Allow for both \n and \r\n end-of-line termination in the proxyauth file located on the PDC. This eliminates the most common installation problem. - The location of the proxyauth file can be changed (for each domain) using the new -S option. Useful when the NETLOGON share is located on a FAT filesystem. Thanks to Colin Manning . 2 Februari 1999, version 0.03 - Support for pass-through authentication (trust relationships) added. Suggested by Matthew Wood . - Bugfix: smb_auth.sh searched for the PDC only. - Many documentation improvements. 9 December 1998, version 0.02 - smb_auth now uses Samba instead of pam_smb. This simplifies the installation of smb_auth and increases platform support. - Access control by user and group: smb_auth now tries to read the file \netlogon\proxyauth. By restricting read access on this file access to the proxy can be controlled. - Easier configuration: - smb_auth is now fully configurable with command-line options (i.e. in squid.conf). No more hacking in the source code. - In most cases it is sufficient to specify just the domain name. smb_auth searches for a working domain controller on each authentication request (note that Squid caches valid requests). - Easier installation: Makefile added. Simply typing "make install" will work for most people. - In a multi-domain situation, users must now enter domain\user instead of user\domain. This conforms to NT notation. Thanks to Jason Haar for pointing this out. 31 July 1998, version 0.01

MSNT Auth v3.0.0
Squid web proxy NT authentication module
Modified by the Squid HTTP Proxy team
Original release by Antonino Iannella, Stellar-X Pty Ltd

Contents

Introduction

This is an authentication module for the Squid proxy server to use an NT domain server.

It originates from the Samba and SMB packages by Andrew Tridgell and Richard Sharpe. It is sourced from the Pike authentication module by William Welliver (hwellive@intersil.com), and the SMB 1.0.1 libraries. Releases up to version 2.0.3 were created by Antonino Iannella (antonino@rager.com.au, http://stellarx.tripod.com). The module is now distributed with Squid, and is maintained by the Squid proxy team as an Open Source effort. Msntauth is released under the GNU General Public License.

basic_msnt_auth follows the standard Squid basic authentication helper protocol. See http://wiki.squid-cache.org/Features/AddonHelpers#Basic_Scheme for details. Problems are logged to syslog.

Msntauth works in environments with NT domain controllers on Windows (TM) NT 4, 2000, and Samba. It only uses the ancient Lanman protocol, the authenticating systems must be configured to accept it.

Installation

Msntauth will be compiled when you compile Squid, using their autoconf system. Refer to Squid documentation for details. If the build is suitable, you can skip this section.

Configuration

As of version 3.0.0, a configuration file is no longer needed. The specification of the domains and domain controllers to use is passed as a list of arguments on the command line. The syntax is: 

basic_msnt_auth domain1/domaincontroller1 [domain2/domaincontroller2 ...]
An arbitrary number of domain controllers can be specified, for any number of daomains. Domain controllers will be attempted in the same order they are configured, until any of them successfully authenticates the user passed by squid. If all domain controllers fail to authenticate the user, then access is denied. Domain controllers can be specified by their NetBios name.

WARNING! this means that a wrong password will be attempted a number of times. Watch out for domain lock-out policies!

Squid.conf changes

Refer to Squid documentation for the required changes to squid.conf. You will need to set the following lines to enable authentication for your access list - 

  acl yourACL proxy_auth REQUIRED
  http_access allow password
  http_access allow yourACL
  http_access deny all

You will also need to review the following directives. The number of msntauth children spawned is set with authenticate_children. The number of children needed is site-dependent, so some experimentation may be required to find the best number. There should be no visible delay in performance with Squid once msntauth is in use. Please see http://www.squid-cache.org/Doc/config/auth_param/ or your squid.conf.default file to check how to configure squid to make use of this helper.

Testing

I strongly urge that Msntauth is tested prior to being used in a production environment. It may behave differently on different platforms. To test it, run it from the command line, and enter username and password pairs separated by a space.

It should behave in the following way - 

 - Press ENTER to get an OK or ERR message.
 - Make sure pressing CTRL-D behaves the same as a carriage return.
 - Make sure pressing CTRL-C aborts the program.
 - Test that entering no details does not result in an OK or ERR message.
 - Test that entering an invalid username and password results in
   an ERR message. Note that if NT guest user access is allowed on
   the PDC, an OK message may be returned instead of ERR.
 - Test that entering an valid username and password results in an OK message.
   Try usernames which are and aren't in the denied/allowed user files,
   if they're in use.
 - Test that entering a guest username and password returns the correct response.

If the above didn't work as expected, you may need to modify the main() function in msntauth.c. Inform the Squid maintainers of any problems.

Usernames and passwords are expected to be URL-encoded (see RFC 1738 for details)

It accepts a username and password on standard input and will return .B OK if the username/password is valid for the domain/machine, or .B ERR if there was some problem. It is possible to authenticate against NT trusted domains specifying the username in the domain\\username Microsoft notation. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-A A Windows Local Group name allowed to authenticate. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-d Write debug info to stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-D A Windows Local Group name not allowed to authenticate. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-O The default Domain against to authenticate. . .SH CONFIGURATION .PP Users that are allowed to access the web proxy must have the Windows NT User Rights .I "\"logon from the network\"" and must be included in the NT LOCAL User Groups specified in the Authenticator's command line. .PP This can be accomplished creating a local user group on the NT machine, grant the privilege, and adding users to it. . .PP You will need to set the following line in .B squid.conf to enable the authenticator: .if !'po4a'hide' .RS .if !'po4a'hide' .B auth_param basic program c:/squid/libexec/basic_sspi_auth.exe [options] .if !'po4a'hide' .RE . .PP You will need to set the following lines in .B squid.conf to enable authentication for your access list: .if !'po4a'hide' .RS .if !'po4a'hide' .B acl aclName proxy_auth REQUIRED .if !'po4a'hide' .br .if !'po4a'hide' .B http_access allow aclName .if !'po4a'hide' .RE . .PP You will need to specify the absolute path to .B basic_sspi_auth.exe in the .B "auth_param basic program" directive. . .SH TESTING .PP I strongly urge that .B basic_sspi_auth.exe is tested prior to being used in a production environment. It may behave differently on different platforms. To test it, run it from the command line. Enter username and password pairs separated by a space. Press ENTER to get an OK or ERR message. Make sure pressing .B CTRL-D behaves the same as a carriage return. Make sure pressing .B CTRL-C aborts the program. .PP Test that entering no details does not result in an .B OK or .B ERR message. .PP Test that entering an invalid username and password results in an .B ERR message. .PP Note that if NT guest user access is allowed on the PDC, an .B OK message may be returned instead of .B ERR .PP Test that entering a valid username and password results in an .B OK message. .PP Test that entering a guest username and password returns the correct response for the site's access policy. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Guido Serassio .PP Based on prior work by .if !'po4a'hide' .I Antonino Iannella (2000) .if !'po4a'hide' .I Andrew Tridgell (1997) .if !'po4a'hide' .I Richard Sharpe (1996) .if !'po4a'hide' .I Bill Welliver (1999) .PP This manual was written by .if !'po4a'hide' .I Guido Serassio .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

Such use of this program is not recommended, but if you absolutely need to then make the program .B setuid .B root .if !'po4a'hide' .RS .if !'po4a'hide' .B chown root basic_getpwnam_auth .if !'po4a'hide' .br .if !'po4a'hide' .B chmod u+s basic_getpwnam_auth .if !'po4a'hide' .RE .PP Please note that in such configurations it is also strongly recommended that the program is moved into a directory where normal users cannot access it, as this mode of operation will allow any local user to brute-force other users passwords. Also note the program has not been fully audited and the author cannot be held responsible for any security issues due to such installations. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Erik Hofman .if !'po4a'hide' .I Robin Elfrink .if !'po4a'hide' .I Giancarlo Razzolini .PP Based on original code by .if !'po4a'hide' .I Jon Thackray . .PP This manual was written by .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

To avoid storing a plaintext * password you can calculate MD5(username:realm:password) when the * user changes their password, and store the tuple username:realm:HA1. * then find the matching username:realm when squid asks for the * HA1. * * This implementation could be improved by using such a triple for * the file format. However storing such a triple does little to * improve security: If compromised the username:realm:HA1 combination * is "plaintext equivalent" - for the purposes of digest authentication * they allow the user access. Password syncronisation is not tackled * by digest - just preventing on the wire compromise. * * Copyright (c) 2003 Robert Collins */ #include "squid.h" #include "digest_common.h" #include "helpers/defines.h" #include "ldap_backend.h" #define PROGRAM_NAME "digest_edirectory_auth" static void GetHHA1(RequestData * requestData) { LDAPHHA1(requestData); } static void ParseBuffer(char *buf, RequestData * requestData) { char *p; requestData->parsed = 0; if ((p = strchr(buf, '\n')) != NULL) *p = '\0'; /* strip \n */ p = NULL; requestData->channelId = strtoll(buf, &p, 10); if (*p != ' ') // not a channel-ID requestData->channelId = -1; else buf = ++p; if ((requestData->user = strtok(buf, "\"")) == NULL) return; if ((requestData->realm = strtok(NULL, "\"")) == NULL) return; if ((requestData->realm = strtok(NULL, "\"")) == NULL) return; requestData->parsed = -1; } static void OutputHHA1(RequestData * requestData) { requestData->error = 0; GetHHA1(requestData); if (requestData->channelId >= 0) printf("%u ", requestData->channelId); if (requestData->error) { SEND_ERR("message=\"No such user\""); return; } printf("OK ha1=\"%s\"\n", requestData->HHA1); } static void DoOneRequest(char *buf) { RequestData requestData; ParseBuffer(buf, &requestData); if (!requestData.parsed) { if (requestData.channelId >= 0) printf("%u ", requestData.channelId); SEND_BH("message=\"Invalid line received\""); return; } OutputHHA1(&requestData); } static void ProcessArguments(int argc, char **argv) { int i; i = LDAPArguments(argc, argv); if (i) exit(i); } int main(int argc, char **argv) { char buf[HELPER_INPUT_BUFFER]; setbuf(stdout, NULL); ProcessArguments(argc, argv); while (fgets(buf, HELPER_INPUT_BUFFER, stdin) != NULL) DoOneRequest(buf); exit(0); } squid3-3.5.12/helpers/digest_auth/eDirectory/edir_ldapext.cc000066400000000000000000000376641262763202500240650ustar00rootroot00000000000000/* * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. */ /* * NDS LDAP helper functions * Copied From Samba-3.0.24 pdb_nds.c and trimmed down to the * limited functionality needed to access the plain text password only * * Original copyright & license follows: * * Copyright (C) Vince Brimhall 2004-2005 * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It handles digest authentication protocol and authenticates against a text file backend. . This program will automatically detect the existence of a concurrecy channel-ID and adjust appropriately. It may be used with any value 0 or above for the auth_param children concurrency= parameter. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-c Accept digest hashed passwords rather than plaintext in the password file . .SH CONFIGURATION .PP Username database file format: .TP 6 - comment lines are possible and should start with a '#'; . .TP - empty or blank lines are possible; . .TP - plaintext entry format is username:password . .TP - HA1 entry format is username:realm:HA1 . .PP To build a directory integrated backend, you need to be able to calculate the HA1 returned to squid. To avoid storing a plaintext password you can calculate .B MD5(username:realm:password) when the user changes their password, and store the tuple .B username:realm:HA1. then find the matching .B username:realm when squid asks for the HA1. .PP This implementation could be improved by using such a triple for the file format. However storing such a triple does little to improve security: If compromised the .B username:realm:HA1 combination is "plaintext equivalent" - for the purposes of digest authentication they allow the user access. Password syncronisation is not tackled by digest - just preventing on the wire compromise. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Robert Collins .PP Based on prior work by .if !'po4a'hide' .I Arjan de Vet .if !'po4a.hide' .I Jon Thackray .PP This manual was written by .if !'po4a'hide' .I Robert Collins .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

It may behave differently on different platforms. . .PP To test it, run it from the command line. Enter username and group pairs separated by a space (username must entered with URL-encoded .I domain%5Cusername syntax). Press .B ENTER to get an .B OK or .B ERR message. .PP Make sure pressing .B CTRL+D behaves the same as a carriage return. .PP Make sure pressing .B CTRL+C aborts the program. . .PP Test that entering no details does not result in an .B OK or .B ERR message. .PP Make sure pressing .B CTRL+D behaves the same as a carriage return. .PP Make sure pressing .B CTRL+C aborts the program. . .PP Test that entering no details does not result in an .B OK or .B ERR message. .PP Test that entering an invalid username and group results in an .B ERR message. .PP Test that entering an valid username and group results in an .B OK message. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Guido Serassio .PP Based on prior work in .B "mswin_check_lm_group (ext_lm_group_acl)" .PP This manual was written by .if !'po4a'hide' .I Guido Serassio .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

Simplifies things a bit and well known encoding. Version 2.14 2004-03-02 Henrik Nordstrom Added -d (debug) flag 2004-02-09 Henrik Nordstrom -E and -S options mismatch 2004-01-08 Henrik Nordstrom Increase buffer size when reading group lookups from Squid Version 2.13 2004-01-05 Henrik Nordstrom Corrected TLS mode (-Z) Version 2.12 2003-03-01 Christoph Lechleitner Added -W option to read bindpasswd from file, e.g. from /etc/ldap.secret 2003-03-01 Juerg Michel Added support for ldap URI via the -H option Version 2.11 2003-01-31 Henrik Nordstrom Packaged as a distribution, with Makefile, README and INSTALL Corrected the squid.conf examples in the manpage and some spelling in the same Separated the changelog/history to a separate ChangeLog file (this file) 2003-01-27 Henrik Nordstrom Cleaned up error messages shown when a nonexisting user tries to log in Version 2.10 2003-01-07 Jon Kinred Fixed user search mode (-F/-u) when -g is not used Version 2.9 2003-01-03 Henrik Nordstrom Fixed missing string termination on ldap_escape_vale, and corrected build problem with LDAPv2 libraries Version 2.8 2002-11-27 Henrik Nordstrom Replacement for ldap_build_filter. Also changed the % codes to %u (user) and %g (group) which is a bit more intuitive. 2002-11-21 Gerard Eviston Fix ldap_search_s error management. This fixes a core dump if there is a LDAP search filter syntax error (possibly caused by malformed input). Version 2.7 2002-10-22: Henrik Nordstrom strwordtok bugfix Version 2.6 2002-09-21: Gerard Eviston -S option to strip NT domain names from login names Version 2.5 2002-09-09: Henrik Nordstrom Added support for user DN lookups (-u -B -F options) Version 2.4 2002-09-06: Henrik Nordstrom Many bugfixes in connection management -g option added, and added support for multiple groups. Prior versions only supported one group and an optional group base RDN Version 2.3 2002-09-04: Henrik Nordstrom Minor cleanups Version 2.2 2002-09-04: Henrik Nordstrom Merged changes from squid_ldap_auth.c - TLS support (Michael Cunningham) - -p option to specify port Documented the % codes to use in -f Version 2.1 2002-08-21: Henrik Nordstrom Support groups or usernames having spaces Version 2.0 2002-01-22: Henrik Nordstrom Added optional third query argument for search RDN 2002-01-22: Henrik Nordstrom Removed unused options, and fully changed name to squid_ldap_match. Version 1.0 2001-07-17: Flavio Pescuma Using the main function from squid_ldap_auth wrote squid_ldap_match. This program replaces the %a and %v (ldapfilter.conf) from the filter template supplied with -f with the two arguments sent by squid. Returns OK if the ldap_search using the composed filter succeeds. Changes from squid_ldap_auth.c: 2001-12-12: Michael Cunningham - Added TLS support and partial ldap version 3 support. 2001-09-05: Henrik Nordstrom - Added ability to specify another default LDAP port to connect to. Persistent connections moved to -P 2001-05-02: Henrik Nordstrom - Support newer OpenLDAP 2.x libraries using the revised Internet Draft API which unfortunately is not backwards compatible with RFC1823.. 2001-04-15: Henrik Nordstrom - Added command line option for basedn - Added the ability to search for the user DN 2001-04-16: Henrik Nordstrom - Added -D binddn -w bindpasswd. 2001-04-17: Henrik Nordstrom - Added -R to disable referrals - Added -a to control alias dereferencing 2001-04-17: Henrik Nordstrom - Added -u, DN username attribute name 2001-04-18: Henrik Nordstrom - Allow full filter specifications in -f -- END -- squid3-3.5.12/helpers/external_acl/LDAP_group/Makefile.am000066400000000000000000000011241262763202500231100ustar00rootroot00000000000000## Copyright (C)

LDAP options are specified as parameters on the command line, while the username(s) and group(s) to be checked against the LDAP directory are specified on subsequent lines of input to the helper, one username/group pair per line separated by a space. .PP As expected by the .B external_acl_type construct of Squid, after specifying a username and group followed by a new line, this helper will produce either .B OK or .B ERR on the following line to show if the user is a member of the specified group. .PP The program operates by searching with a search filter based on the users user name and requested group, and if a match is found it is determined that the user belongs to the group. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .BI "\-a " never|always|search|find When to dereference aliases. Defaults to 'never' .IP .BI never dereference aliases (default), .BI always dereference aliases, only while .BR search ing or only to .B find the base object . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-b " "basedn " .B REQUIRED. Specifies the base DN under which the groups are located. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-B " "basedn " Specifies the base DN under which the users are located (if different) . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-c " connect_timeout" Specify timeout used when connecting to LDAP servers (requires Netscape LDAP API libraries) . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-d Debug mode where each step taken will get reported in detail. Useful for understanding what goes wrong if the result is not what was expected. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-D " "binddn " "\-w " password The DN and password to bind as while performing searches. Required if the LDAP directory does not allow anonymous searches. .IP As the password needs to be printed in plain text in your Squid configuration and will be sent on the command line to the helper it is strongly recommended to use a account with minimal associated privileges. This to limit the damage in case someone could get hold of a copy of your Squid configuration file or extracts the password used from a process listing. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-D " "binddn " "\-W " "secretfile " The DN and the name of a file containing the password to bind as while performing searches. .IP Less insecure version of the former parameter pair with two advantages: The password does not occur in the process listing, and the password is not being compromised if someone gets the squid configuration file without getting the secretfile. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-E " certpath Enable LDAP over SSL (requires Netscape LDAP API libraries) . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-f " filter LDAP search filter used to search the LDAP directory for any matching group memberships. .BR In the filter .B %u will be replaced by the user name (or DN if the .B \-F or .B \-u options are used) and .B %g by the requested group name. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "\-F " filter LDAP search filter used to search the LDAP directory for any matching users. .BR In the filter .B %s will be replaced by the user name. If .B % is to be included literally in the filter then use .B %% . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-g" Specifies that the first query argument sent to the helper by Squid is a extension to the basedn and will be temporarily added in front of the global basedn for this query. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-h " ldapserver" Specify the LDAP server to connect to . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-H " ldapuri" Specity the LDAP server to connect to by a LDAP URI (requires OpenLDAP libraries) . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-K Strip Kerberos Realm component from user names (@ separated) . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-p " ldapport" Specify an alternate TCP port where the LDAP server is listening if other than the default LDAP port 389. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-P Use a persistent LDAP connection. Normally the LDAP connection is only open while verifying a users group membership to preserve resources at the LDAP server. This option causes the LDAP connection to be kept open, allowing it to be reused for further user validations. Recommended for larger installations. . .if !'po4a'hide' .TP .if !'po4a'hide' .BI \-R Do not follow referrals . .if !'po4a'hide' .TP .if !'po4a'hide' .BI "-s " base|one|sub search scope.

ext_lm_group_acl \- Squid external ACL helper to check Windows users group membership. .PP Version 1.22 . .SH SYNOPSIS .if !'po4a'hide' .B ext_lm_group_acl .if !'po4a'hide' .B "[\-D " domain .if !'po4a'hide' .B "] [\-cdhGP]" . .SH DESCRIPTION .B ext_lm_group_acl is an installed binary in Squid for Windows builds. .PP This helper must be used in with an authentication scheme (typically Basic or NTLM) based on Windows NT/2000 domain users (LM mode). .PP It reads from the standard input the domain username and a list of groups and tries to match each against the groups membership of the specified username. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-c Use case insensitive compare. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-d Write debug info to stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-D domain Specify the default user's domain. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-G Start helper in Domain Global Group mode. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-h Display the binary help and command line syntax info using stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-P Use ONLY PDCs for group validation. . .SH CONFIGURATION .if !'po4a'hide' .RS .if !'po4a'hide' .B external_acl_type NT_global_group %LOGIN c:/squid/libexec/ext_lm_group_acl.exe -G .if !'po4a'hide' .br .if !'po4a'hide' .B external_acl_type NT_local_group %LOGIN c:/squid/libexec/ext_lm_group_acl.exe .if !'po4a'hide' .br .if !'po4a'hide' .br .if !'po4a'hide' .B acl GProxyUsers external NT_global_group GProxyUsers .if !'po4a'hide' .br .if !'po4a'hide' .B acl LProxyUsers external NT_local_group LProxyUsers .if !'po4a'hide' .br .if !'po4a'hide' .B acl password proxy_auth REQUIRED .if !'po4a'hide' .br .if !'po4a'hide' .br .if !'po4a'hide' .B http_access allow password GProxyUsers .if !'po4a'hide' .br .if !'po4a'hide' .B http_access allow password LProxyUsers .if !'po4a'hide' .br .if !'po4a'hide' .B http_access deny all .if !'po4a'hide' .RE . .PP In the previous example all validated NT users member of GProxyUsers Global domain group or member of LProxyUsers machine local group are allowed to use the cache. . .PP Groups with spaces in name, for example .B "Domain Users" , must be quoted and the acl data ( .B "Domain Users" ) must be placed into a separate file included by specifying .B "/path/to/file" . The previous example will be: .if !'po4a'hide' .RS .if !'po4a'hide' acl ProxyUsers external NT_global_group "c:/squid/etc/DomainUsers.txt" .if !'po4a'hide' .RE . The .B DomainUsers.txt file will contain only the following line: .if !'po4a'hide' .RS .B "Domain Users" .if !'po4a'hide' .RE . .PP .B NOTE: The standard group name comparison is case sensitive, so group name must be specified with same case as in the NT/2000 Domain. It's possible to enable case insensitive group name comparison ( .B \-c ), but on some not-english locales, the results can be unexpected. . .PP .B NOTE: Native WIN32 NTLM and Basic Helpers must be used without the .B \-A and .B \-D switches. .PP Refer to Squid documentation for the more details on squid.conf. . .SH TESTING .PP I strongly recommend that .B ext_lm_group_acl is tested prior to being used in a production environment. It may behave differently on different platforms. . .PP To test it, run it from the command line. Enter username and group pairs separated by a space (username must entered with URL-encoded .I domain%5Cusername syntax).

Taking an identity token to be validated (as determined by the external_acl_type format) it returns a username or tag associated with the identity token passed in. Common forms of identifiers are IP address, EUI (MAC) address, passwords, or UUID tokens. This program uses Squid concurrency support. =head1 OPTIONS =over 12 =item B<--dsn> Database DSN.

Use of the groups is optional, unless the '-G' option has been passed. Please note that you need to specify the full LDAP object for this, as shown above. . .SH KNOWN ISSUES .PP IPv6 support has yet to be tested in a real IPv6 environment, but the code is in place to read IPv6 networkAddress fields, please attempt this in a TESTING environment first. Please contact the author regarding IPv6 support development. . .PP There is a known issue regarding Novell's Client for Windows, that is mostly fixed by using version 4.91 SP3+, with the 'Auto-Reconnect' feature not re-populating the networkAddress field in eDirectory. . .PP I have also experienced an issue related to using NetWare 6.5 (SP6 and lower?) and connection licensing. It appears that whenever a server runs low on connection licenses, that it I sometimes does not populate the networkAddress fields correctly. . .PP Majority of Proxy Authentication issues can be resolved by having the users' .B reboot if their networkAddress is not correct, or using .B basic_ldap_auth as a fallback. Check ConsoleOne, etc to verify their networkAddress fields to troubleshoot. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Chad E.

An external helper for the Squid external acl scheme. .PP It works by reading a pair composed by an IP address and an username on STDIN and matching it against a configuration file. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-d Write debug info to stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-f file Configuration .B file to load. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-h Display the binary help and command line syntax info using stderr. . .SH CONFIGURATION .PP The .B squid.conf configuration for the external ACL should be: .if !'po4a'hide' .RS .if !'po4a'hide' .B external_acl_type type-name %SRC %LOGIN /path/to/ext_file_userip_acl -f /path/to/config.file .if !'po4a'hide' .RE .PP If the helper program finds a matching username/ip in the configuration file, it returns .B OK , otherwise it returns .B ERR . .PP The configuration file format is as follows: .if !'po4a'hide' .RS .if !'po4a'hide' ip_addr[/netmask] username|@group|ALL|NONE .if !'po4a'hide' .RE .PP Where .B ip_addr is a dotted quad format IP address, the .B netmask must be in dotted quad format too. .PP When the second parameter is prefixed with an .B "@" , the program will lookup the .B "/etc/group" file entry for the specified username. .PP There are other two directives, .B ALL and .B NONE , which mean \"any user on this IP address may authenticate\" or \"no user on this IP address may authenticate\". . .SH AUTHOR This program was written by .if !'po4a'hide' .I Rodrigo Campos .PP This manual was written by .if !'po4a'hide' .I Rodrigo Campos .if !'po4a'hide' .I Amos Jeffries . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

All rights reserved. -------------------------------------------------------------------------------- squid_kerb_ldap Read Me Markus Moeller June 2, 2007 1 Introduction squid_kerb_ldap is a reference implementation that supports SASL/GSSAPI authentication to an ldap server. It is mainly intended to connect to Active Directory or Openldap based ldap servers. For AD it checks the memberof attribute to determine if a user is member of a group. For non AD it checks the memberuid attribute to determine if a user is member of a group and if not it checks if the primary group matches. Currently, squid_kerb_ldap supports Squid 2.6 on Linux. squid_auth_ldap requires either MIT or Heimdal Kerberos libraries and header files. 2 Building and Installation ./configure make Copy the helper squid_kerb_ldap to an apropriate directory. 3 Configuration a) Configure IE or Firefox to point to the squid proxy by using the fqdn. IE and Firefox will use the fqdn to query for a HTTP/fqdn Kerberos service principal. b) Create a keytab which contains the HTTP/fqdn Kerberos service principal and place it into a directory where the squid run user can read the keytab. c) Add the following line to squid.conf auth_param negotiate program /usr/sbin/squid_kerb_auth auth_param negotiate children 10 auth_param negotiate keep_alive on external_acl_type squid_kerb_ldap ttl=3600 negative_ttl=3600 %LOGIN /usr/sbin/squid_kerb_ldap -g GROUP@ acl ldap_group_check external squid_kerb_ldap http_access allow ldap_group_check If a ntlm helper is used too add a -N option to map the netbios name to a Kerberos realm e.g. external_acl_type squid_kerb_ldap ttl=3600 negative_ttl=3600 %LOGIN /usr/sbin/squid_kerb_ldap -g GROUP@ -N NETBIOS@KERBEROS.REALM acl ldap_group_check external squid_kerb_ldap http_access allow ldap_group_check d) Modify squid startup file Add the following lines to the squid startup script to point squid to a keytab file which contains the HTTP/fqdn service principal for the default Kerberos domain. The fqdn must be the proxy name set in IE or firefox. You can not use an IP address. KRB5_KTNAME=/etc/squid/HTTP.keytab export KRB5_KTNAME If you use a different Kerberos domain than the machine itself is in you can point squid to the seperate Kerberos config file by setting the following environmnet variable in the startup script. KRB5_CONFIG=/etc/krb5-squid.conf export KRB5_CONFIG 4 Miscellaneous The -i options creates informational messages whereas -d creates full debug output If squid_kerb_ldap doesn't determine for some reason the right service ldap server you can provide it with -u BIND_DN -p BIND_PW -b BIND_PATH -l LDAP_URL STARTTLS/SSL is supported and the -a options disables server certificate checks If you serve multiple Kerberos realms add a HTTP/fqdn@REALM service principal per realm to the HTTP.keytab file and use the -s GSS_C_NO_NAME option with squid_kerb_auth. squid_kerb_ldap will determine automagically the right ldap server. The following method is used: 1) For user@REALM 1) Query DNS for SRV record _ldap._tcp.REALM 2) Query DNS for A record REALM 3) Use LDAP_URL if given 2) For user 2) Use LDAP_URL if given The Groups to check against are determined as follows: 1 For user@REALM 1) Use values given by -g option which contain a @REALM e.g. -g GROUP1@REALM:GROUP2@REALM 2) Use values given by -g option which contain a @ only e.g. -g GROUP1@:GROUP2@ 3) Use values given by -g option which do not contain a realm e.g. -g GROUP1:GROUP2 1 For user 3) Use values given by -g option which do not contain a realm e.g. -g GROUP1:GROUP2 To support Non-ASCII character use -t or -t @ instead of -g where GROUP is the hex UTF-8 representation e.g. -t 6d61726b7573 instead of -g markus The REALM must still be based on the ASCII character set. If REALM contains also non ASCII characters use -T @ where GROUP and REALM are hex UTF-8 representation e.g. -T 6d61726b7573@57494e3230303352322e484f4d45 instead of -g markus@WIN2003R2.HOME For a translation of hex UTF-8 see for example http://www.utf8-chartable.de/unicode-utf8-table.pl squid3-3.5.12/helpers/external_acl/kerberos_ldap_group/cert_tool000066400000000000000000000047231262763202500250750ustar00rootroot00000000000000#!/bin/sh # ## Copyright (C) 1996-2015 The Squid Software Foundation and contributors ## ## Squid software is distributed under GPLv2+ license and includes ## contributions from numerous individuals and organizations. ## Please see the COPYING and CONTRIBUTORS files for details. ## # ----------------------------------------------------------------------------- # # Author: Markus Moeller (markus_moeller at compuserve.com) # # Copyright (C) 2007 Markus Moeller.

Options are specified as parameters on the command line, while the username (e.g. .B user , .B user@REALM , .B NDOMAIN\\user ) to be checked against the LDAP directory are specified on subsequent lines of input to the helper, one username per line. .PP .B ext_kerberos_ldap_group_acl will determine the ldap server name from DNS SRV and/or A records or a local hosts file (e.g. for the Kerberos Realm .B SUSE.HOME it will look for an SRV record .B _ldap._tcp.SUSE.HOME and an A record .B SUSE.HOME or a .B SUSE.HOME hosts entry). If no domain information is available from the username the LDAP server will be determined through the command line options. .PP .B ext_kerberos_ldap_group_acl requires as a minimum the .B \-g , .B \-t or .B \-T option which provides the LDAP group name the user has to belong too. For Active Directory a recursive group lookup is implemented until a max depth specified by .B \-m depth. For other LDAP servers a RFC2307bis schema of groups is assumed. .PP Different group names can be specified for different domains using a group@domain syntax. As expected by the .B external_acl_type construct of Squid, after specifying a username and group followed by a new line, this helper will produce either .B OK or .B ERR on the following line to show if the user is a member of the specified group. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-h Display the binary help and command line syntax info using stderr. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-d Write debug messages to stderr. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-i Write informational messages to stderr. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-s Use SSL for the LDAP connection. .IP The CA certificate file can be set via the environment variable TLS_CACERTFILE (default /etc/ssl/certs/cert.pem) (OpenLDAP). .IP The SSL certificate database can be set via the environment variable SSL_CERTDBPATH (default /etc/certs) (Sun and Mozilla LDAP SDK). .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-a Allow SSL without certificate verification. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-D Realm Default Kerberos domain to use for usernames which do not contain domain information (e.g. for users using basic authentication). .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-N Netbios\-Realm\-List A list of Netbios name mappings to Kerberos domain names of the form Netbios\-Name@Kerberos\-Realm[:Netbios\-Name@Kerberos\-Realm] (e.g. for users using NTLM authentication). .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-m Max\-Depth Maximal depth of recursive group search. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-u Ldap\-User Username for LDAP server. .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-p Ldap\-Password Password for LDAP server. .IP As the password needs to be printed in plain text in your Squid configuration it is strongly recommended to use an account with minimal associated privileges.

You can not use an IP address. .if !'po4a'hide' .P .if !'po4a'hide' .ft CR .if !'po4a'hide' .nf .if !'po4a'hide' KRB5_KTNAME=/etc/squid/HTTP.keytab .if !'po4a'hide' export KRB5_KTNAME .if !'po4a'hide' .fi .if !'po4a'hide' .ft . If you use a different Kerberos domain than the machine itself is in you can point squid to the seperate Kerberos config file by setting the following environmnet variable in the startup script. .if !'po4a'hide' .P .if !'po4a'hide' .ft CR .if !'po4a'hide' .nf .if !'po4a'hide' KRB5_CONFIG=/etc/krb5\-squid.conf .if !'po4a'hide' export KRB5_CONFIG .if !'po4a'hide' .fi .if !'po4a'hide' .ft . .B ext_kerberos_ldap_group_acl will determine automagically the right ldap server. The following method is used: 1) For user@REALM a) Query DNS for SRV record _ldap._tcp.REALM b) Query DNS for A record REALM c) Use LDAP_URL if given 2) For user a) Use domain \-D REALM and follow step 1) b) Use LDAP_URL if given The Groups to check against are determined as follows: 1) For user@REALM a) Use values given by \-g option which contain a @REALM e.g. \-g GROUP1@REALM:GROUP2@REALM b) Use values given by \-g option which contain a @ only e.g. \-g GROUP1@:GROUP2@ c) Use values given by \-g option which do not contain a realm e.g. \-g GROUP1:GROUP2 2) For user a) Use values given by \-g option which do not contain a realm e.g. \-g GROUP1:GROUP2 3) For NDOMAIN\\user a) Use realm given by \-N NDOMAIN@REALM and then use values given by \-g option which contain a @REALM e.g. \-g GROUP1@REALM:GROUP2@REALM To support Non\-ASCII character use \-t GROUP or \-t GROUP@REALM instead of \-g where GROUP is the hex UTF\-8 representation e.g. \-t 6d61726b7573 instead of \-g markus The REALM must still be based on the ASCII character set. If REALM contains also non ASCII characters use \-T GROUP@REALM where GROUP and REALM are hex UTF\-8 representation e.g. \-T 6d61726b7573@57494e3230303352322e484f4d45 instead of \-g markus@WIN2003R2.HOME For a translation of hex UTF\-8 see for example http://www.utf8\-chartable.de/unicode\-utf8\-table.pl The ldap server list can be: server \- In this case server can be used for all Kerberos domains server@ \- In this case server can be used for all Kerberos domains server@domain \- In this case server can be used for Kerberos domain domain server1a@domain1:server1b@domain1:server2@domain2:server3@:server4 \- A list is build with a colon as seperator . .SH AUTHOR This program was written by .if !'po4a'hide' .I Markus Moeller .PP This manual was written by .if !'po4a'hide' .I Markus Moeller . .SH COPYRIGHT .PP * Copyright (C) 1996\-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

The timeout is based either on idle use ( .B \-t ) or a fixed period of time ( .B \-T ). The former is suitable for displaying terms and conditions to a user; the latter is suitable for the display of advertisments or other notices (both as a splash page \- see config examples in the wiki online). The session helper can also be used to force users to re\-authenticate if the .B %LOGIN and .B \-a are both used. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B "\-t timeout" Idle timeout for any session. The default if not specified (set to 3600 seconds). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-T timeout" Fixed timeout for any session. This will end the session after the timeout regardless of a user's activity. If used with .B active mode, this will terminate the user's session after .B timeout , after which another .B LOGIN will be required. .B LOGOUT will reset the session and timeout. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-b path" .B Path to persistent database. If a file is specified then that single file is used as the database. If a path is specified, a Berkeley DB database environment is created within the directory. The advantage of the latter is better database support between multiple instances of the session helper. Using multiple instances of the session helper with a single database file will cause synchronisation problems between processes. If this option is not specified the session details will be kept in memory only and all sessions will reset each time Squid restarts its helpers (Squid restart or rotation of logs). . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-a Active mode.

The administrator can define a time budget (e.g. 1 hour per day) which is enforced through this helper. . .SH OPTIONS . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-b database" .B Filename of persistent database. This defaults to ext_time_quota.db in Squids state directory. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-p pauselen" .B Pauselen is given in seconds and defines the period between two requests to be treated as part of the same session. Pauses shorter than this value will be counted against the quota, longer ones ignored. Default is 300 seconds (5 minutes). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-l logfile" .B Filename where all logging and debugging information will be written. If none is given, then stderr will be used and the logging will go to Squids main cache.log. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-d" Enables debug logging in the logfile. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-h" show a short command line help. . .if !'po4a'hide' .TP .if !'po4a'hide' .B configfile This file contains the definition of the time budgets for the users. .PP . .SH CONFIGURATION .PP The time quotas of the users are defined in a text file typically residing in /etc/squid/time_quota. Any line starting with "#" contains a comment and is ignored. Every line must start with a user followed by a time budget and a corresponding time period separated by "/". Here is an example file: .PP .if !'po4a'hide' .RS # user budget / period .if !'po4a'hide' .br .if !'po4a'hide' .B john 8h / 1d .if !'po4a'hide' .br .if !'po4a'hide' .B littlejoe 1h / 1d .if !'po4a'hide' .br .if !'po4a'hide' .B babymary 30m / 1w .if !'po4a'hide' .br .if !'po4a'hide' .RE .PP John has a time budget of 8 hours every day, littlejoe is only allowed 1 hour and the poor babymary only 30 minutes a week. .PP You can use "s" for seconds, "m" for minutes, "h" for hours, "d" for days and "w" for weeks. Numerical values can be given as integer values or with a fraction. E.g. "0.5h" means 30 minutes. .PP This helper is configured in .B squid.conf using the .B external_acl_type directive then access controls which use it to allow or deny. . .PP Here is an example. .PP .if !'po4a'hide' .RS # Ensure that users have a valid login. We need their username. .if !'po4a'hide' .br .if !'po4a'hide' .br .if !'po4a'hide' .B acl users proxy_auth REQUIRED .if !'po4a'hide' .br .if !'po4a'hide' .B http_access deny !users .if !'po4a'hide' .br # Define program and quota file .if !'po4a'hide' .br .if !'po4a'hide' .B external_acl_type time_quota ttl=60 children-max=1 %LOGIN /usr/libexec/ext_time_quota_acl /etc/squid/time_quota .if !'po4a'hide' .br .if !'po4a'hide' .br .if !'po4a'hide' .B acl noquota src all .if !'po4a'hide' .br .if !'po4a'hide' .B acl time_quota external time_quota .if !'po4a'hide' .br .if !'po4a'hide' .B deny_info ERR_ACL_TIME_QUOTA_EXCEEDED noquota .if !'po4a'hide' .br .if !'po4a'hide' .B http_access deny !time_quota noquota .if !'po4a'hide' .RE . .PP In this example, after restarting Squid it should allow access only for users as long as they have time budget left. If the budget is exceeded the user will be presented with an error page informing them. .PP In this example we use separate .B users access control and .B noquota ACL in order to keep the username and password prompt and the quota-exceeded messages separated. . .PP User is just a unique key value. The above example uses %LOGIN and the username but any of the .B external_acl_type format tags can be substituted in its place. .B %EXT_TAG , .B %LOGIN , .B %IDENT , .B %EXT_USER , .B %SRC , .B %SRCEUI48 , and .B %SRCEUI64 are all likely candidates for client identification. The Squid wiki has more examples at http://wiki.squid-cache.org/ConfigExamples. . .SH LIMITATIONS .PP This helper only controls access to the Internet through HTTP. It does not control other protocols, like VOIP, ICQ, IRC, FTP, IMAP, SMTP or SSH. . .PP Desktop browsers are typically able to deal with authentication to HTTP proxies like .B squid . But more and more different programs and devices (smartphones, games on mobile devices, ...) are using the Internet over HTTP. These devices are often not able to work through an authenticating proxy. Means other than %LOGIN authentication are required to authorize these devices and software. . .PP A more general control to Internet access could be a captive portal approach (such as pfSense or ChilliSpot) using %SRC, %SRCEUI48 and %SRCEUI64 as keys or maybe a 802.11X solution. But the latter is often not supported by mobile devices. . .SH IMPLEMENTATION .PP When the helper is called it will be asked if the current user is allowed to access squid. The helper will reduce the remaining time budget of this user and return .B OK if there is budget left. Otherwise it will return .B ERR . . .PP The .B ttl=N parameter in .B squid.conf determines how often the helper will be called, the example config uses a 1 minute TTL. The interaction is that Squid will only call the helper on new requests .B if there has been more than TTL seconds passed since last check. This handling creates an amount of slippage outside the quota by whatever amount is configured. TTL can be set as short as desired, down to and including zero. Though values of 1 or more are recommended due to a quota resolution of one second. . .PP If the configured time period (e.g. "1w" for babymary) is over, the time budget will be restored to the configured value thus allowing the user to access squid with a fresh budget. . .PP If the time between the current request and the previous request is greater than .B pauselen (default 5 minutes and adjustable with command line parameter .B "-p" ), the current request will be considered as a new request and the time budget will not be decreased. If the time is less than .B pauselen , then both requests will be considered as part of the same active time period and the time budget will be decreased by the time difference. This allows the user to take arbitrary breaks during Internet access without losing their time budget. . .SH FURTHER IDEAS The following ideas could further improve this helper. Maybe someone wants to help? Any support or feedback is welcome! .if !'po4a'hide' .TP There should be a way for a user to see their configured and remaining time budget. This could be realized by implementing a web page accessing the database of the helper showing the corresponding data.

The last parameter tells squid which log format to use when writing lines to the log daemon. Presently B format is supported. =over 4 =item mysql_host:port Host where the mysql server is running. If left empty, 'localhost' is assumed. =item database Name of the database to connect to. If left empty, 'squid_log' is assumed. =item table Name of the database table where log lines are stored. If left empty, 'access_log' is assumed. =item username Username to use when connecting to the database. If left empty, 'squid' is assumed. =item password Password to use when connecting to the database. If left empty, no password is used. =back To leave all fields to their default values, you can use a single slash: access_log daemon:/ squid To specify only the database password, which by default is empty, you must leave unspecified all the other parameters by using null strings: access_log daemon://///password squid =head3 logfile_daemon directive This is the current way of telling squid where the logfile daemon resides. logfile_daemon /path/to/squid/libexec/logfile-daemon_mysql.pl The script must be copied to the location specified in the directive. =head2 Database configuration Let's call the database 'squid_log' and the log table 'access_log'. The username and password for the db connection will be both 'squid'. =head3 Database Create the database: CREATE DATABASE squid_log; =head3 User Create the user: GRANT INSERT,SELECT,CREATE ON squid_log.* TO 'squid'@'localhost' IDENTIFIED BY 'squid'; FLUSH PRIVILEGES; Note that only CREATE, INSERT and SELECT privileges are granted to the 'squid' user. This ensures that the logfile daemon script cannot change or modify the log entries. =head3 Table The Daemon will attempt to initialize this table if none exists when it starts. The table created should look like: CREATE TABLE access_log ( id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY, time_since_epoch DECIMAL(15,3), time_response INTEGER, ip_client CHAR(15), ip_server CHAR(15), http_status_code VARCHAR(10), http_reply_size INTEGER, http_method VARCHAR(20), http_url TEXT, http_username VARCHAR(20), http_mime_type VARCHAR(50), squid_hier_status VARCHAR(20), squid_request_status VARCHAR(20) ); =head1 VERSION INFORMATION This document refers to C script version 0.5.

You might want to append "ENGINE=MYISAM" at the end of the table creation code in the above SQL script. Indexes should be created according to the queries that are more frequently run. The DDL script only creates an implicit index for the primary key column. =head1 TODO =head2 Table cleanup This script currently implements only the C (i.e. "append a line to the log") command, therefore the log lines are never purged from the table. This approach has an obvious scalability problem. One solution would be to implement e.g. the "rotate log" command in a way that would calculate some summary values, put them in a "summary table" and then delete the lines used to caluclate those values.

All rights reserved. -------------------------------------------------------------------------------- squid_kerb_auth Read Me Markus Moeller May 12, 2007 1 Introduction squid_kerb_auth is a reference implementation that supports authentication via the Negotiate RFC 4559 for proxies. It decodes RFC 2478 SPNEGO GSS-API tokens from IE7 either through helper functions or via SPNEGO supporting Kerberos libraries and RFC 1964 Kerberos tokens from Firefox on Linux. Currently, squid_kerb_auth supports Squid 2.6 on Linux. squid_auth_kerb requires either MIT or Heimdal Kerberos libraries and header files. 2 Building and Installation Run ./configure for help use ./configure --help Copy the helper squid_kerb_auth to an apropriate directory. 3 Configuration a) Configure IE or Firefox to point to the squid proxy by using the fqdn. IE and Firefox will use the fqdn to query for a HTTP/fqdn Kerberos service principal. b) Create a keytab which contains the HTTP/fqdn Kerberos service principal and place it into a directory where the squid run user can read the keytab. c) Add the following line to squid.conf auth_param negotiate program /usr/sbin/squid_kerb_auth auth_param negotiate children 10 auth_param negotiate keep_alive on d) Modify squid startup file Add the following lines to the squid startup script to point squid to a keytab file which contains the HTTP/fqdn service principal for the default Kerberos domain. The fqdn must be the proxy name set in IE or firefox. You can not use an IP address.

The keytab name can also be provided by the \-k option. The fqdn must be the proxy name set in IE or firefox. You can not use an IP address. KRB5_KTNAME=/etc/squid/HTTP.keytab export KRB5_KTNAME If you use a different Kerberos domain than the machine itself is in you can point squid to the seperate Kerberos config file by setting the following environmnet variable in the startup script. KRB5_CONFIG=/etc/krb5\-squid.conf export KRB5_CONFIG Kerberos can keep a replay cache to detect the reuse of Kerberos tickets (usually only possible in a 5 minute window) . If squid is under high load with Negotiate(Kerberos) proxy authentication requests the replay cache checks can create high CPU load. If the environment does not require high security the replay cache check can be disabled for MIT based Kerberos implementations by adding the below to the startup script or use the \-t none option. KRB5RCACHETYPE=none export KRB5RCACHETYPE If negotiate_kerberos_auth doesn't determine for some reason the right service principal you can provide it with \-s HTTP/fqdn. If you serve multiple Kerberos realms add a HTTP/fqdn@REALM service principal per realm to the HTTP.keytab file and use the \-s GSS_C_NO_NAME option with negotiate_kerberos_auth. . .SH AUTHOR This program was written by .if !'po4a'hide' .I Markus Moeller .PP This manual was written by .if !'po4a'hide' .I Markus Moeller . .SH COPYRIGHT .PP * Copyright (C) 1996\-2014 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. .PP This program and documentation is copyright to the authors named above. .PP Distributed under the GNU General Public License (GNU GPL) version 2 or later (GPLv2+). . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS Bug reports need to be made in English.

It provides native access to the Security Service Provider Interface of Windows for authenticating with NTLM / NTLMv2. It has automatic support for NTLM NEGOTIATE packets. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B \-A Specify a Windows Local Group name allowed to authenticate. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-d Write debug info to stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-D Specify a Windows Local Group name which is to be denied authentication. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-h Display the binary help and command line syntax info using stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B \-v Enables verbose NTLM packet debugging. . .SH CONFIGURATION .PP .B Allowing Users .PP Users that are allowed to access the web proxy must have the Windows NT User Rights "logon from the network". .PP Optionally the authenticator can verify the NT LOCAL group membership of the user against the User Group specified in the Authenticator's command line. .PP This can be accomplished creating a local user group on the NT machine, grant the privilege, and adding users to it, it works only with MACHINE Local Groups, not Domain Local Groups. .PP Better group checking is available with external ACL, see .B ext_ad_group_acl.exe documentation. .PP .B squid.conf typical minimal required changes: .if !'po4a'hide' .RS .if !'po4a'hide' .B auth_param ntlm program c:/squid/libexec/ntlm_sspi_auth.exe .if !'po4a'hide' .B auth_param ntlm children 5 .if !'po4a'hide' .br .if !'po4a'hide' .B acl password proxy_auth REQUIRED .if !'po4a'hide' .br .if !'po4a'hide' .B http_access allow password .if !'po4a'hide' .B http_access deny all .if !'po4a'hide' .RE . .PP Refer to Squid documentation for more details. . .PP Internet Explorer has some problems with .B ftp:// URLs when handling internal Squid FTP icons.

Chunk size is rounded up to * MEM_PAGE_SIZE (4K), trying to have chunks in multiples of VM_PAGE size. * Minimum Chunk size is MEM_CHUNK_SIZE (16K). * A number of items fits into a single chunk, depending on item size. * Maximum number of items per chunk is limited to MEM_MAX_FREE (65535). * * We populate Chunk with a linkedlist, each node at first word of item, * and pointing at next free item. Chunk->FreeList is pointing at first * free node. Thus we stuff free housekeeping into the Chunk itself, and * omit pointer overhead per item. * * Chunks are created on demand, and new chunks are inserted into linklist * of chunks so that Chunks with smaller pointer value are placed closer * to the linklist head.

For alpha, this is "rpcc" which is 32-bit counter and * wraps every few seconds. Currently, no handling of wrapping counters * is implemented. Other CPU's are also not covered. Potentially all * modern CPU's has similar counters. * * Usage. * Insert macro PROF_state(probename) in strategic places in code. * PROF_start(probename); * ... section of code measured ... * PROF_stop(probename); * * probename must be added to the xprof_type.h enum list * with prepended "XPROF_" string. * * \section description Description. * \par PROF * gathers stats per probename into structures. It indexes these * structures by enum type index in an array. * * \par PROF * records best, best, average and worst values for delta time, * also, if UNACCED is defined, it measures "empty" time during which * no probes are in measuring state. This allows to see time "unaccounted" * for. If OVERHEAD is defined, additional calculations are made at every * probe to measure approximate overhead of the probe code itself. * * \par * Probe data is stored in linked-list, so the more probes you define, * the more overhead is added to find the deepest nested probe. To reduce * average overhead, linked list is manipulated each time PR_start is * called, so that probe just started is moved 1 position up in linkedlist. * This way frequently used probes are moved closer to the head of list, * reducing average overhead. * Note that all overhead is on the scale of one hundred of CPU clock * ticks, which on the scale of submicroseconds. Yet, to optimise really * fast and frequent sections of code, we want to reduce this overhead * to absolute minimum possible. * * \par * For actual measurements, probe overhead cancels out mostly. Still, * do not take the measured times as facts, they should be viewed in * relative comparison to overall CPU time and on the same platform. * * \par * Every 1 second, Event within squid is called that parses gathered * statistics of every probe, and accumulates that into historical * structures for last 1,5,30 secs, 1,5,30 mins, and 1,5 and 24 hours. * Each second active probe stats are reset, and only historical data * is presented in cachemgr output. * * \section reading Reading stats. * \par * "Worst case" may be misleading. Anything can happen at any section * of code that could delay reaching to probe stop. For eg. system may * need to service interrupt routine, task switch could occur, or page * fault needs to be handled. In this sense, this is quite meaningless * metric. "Best case" shows fastest completion of probe section, and * is also somewhat useless, unless you know that amount of work is * constant. Best metric to watch is "average time" and total cumulated * time in given timeframe, which really show percentage of time spent * in given section of code, and its average completion time. This data * could be used to detect bottlenecks withing squid and optimise them. * * \par * TOTALS are quite off reality. Its there just to summarise cumulative * times and percent column. Percent values over 100% shows that there * have been some probes nested into each other. * */ #include "squid.h" #include "profiler/Profiler.h" #if USE_XPROF_STATS #include #if HAVE_GNUMALLLOC_H #include #elif HAVE_MALLOC_H #include #endif #if HAVE_UNISTD_H #include #endif /* Exported Data */ TimersArray *xprof_Timers = NULL; /* Private stuff */ /* new stuff */ #define MAXSTACKDEPTH 512 struct _callstack_entry { int timer; /* index into timers array */ const char *name; hrtime_t start, stop, accum; }; struct _callstack_entry cstack[MAXSTACKDEPTH]; int cstack_head = 0; #if defined(_MSC_VER) /* Microsoft C Compiler ONLY */ static __inline void #else static inline void #endif xprof_update(xprof_stats_data * head) { if (head->delta < head->best) head->best = head->delta; if (head->worst < head->delta) head->worst = head->delta; head->summ += head->delta; ++head->count; } static xprof_stats_data *xp_UNACCOUNTED; static int xprof_inited = 0; static void xprof_InitLib(void) { if (xprof_inited) return; xprof_Timers = static_cast(calloc(XPROF_LAST + 2, sizeof(xprof_stats_node))); xprof_Timers[XPROF_PROF_UNACCOUNTED]->name = "PROF_UNACCOUNTED"; xprof_Timers[XPROF_PROF_UNACCOUNTED]->accu.start = get_tick(); xp_UNACCOUNTED = &xprof_Timers[XPROF_PROF_UNACCOUNTED]->accu; cstack_head = 0; xprof_inited = 1; } void xprof_start(xprof_type type, const char *timer) { hrtime_t tt = get_tick(); if (!xprof_inited) xprof_InitLib(); /* If nested, stop current stack frame */ if (cstack_head > 0) { cstack[cstack_head - 1].accum += get_tick() - cstack[cstack_head - 1].start; cstack[cstack_head - 1].start = -1; } /* Are we at the first level?

In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

If we are lucky to stop before * we overrun any buffers, we still may have garbage (e.g. half of ETag) in * the buffer. * * MemBuffer: * ---------- * * MemBuffer is a memory-resident buffer with printf()-like interface. It * hides all offest handling and overflow checking. Moreover, it has a * build-in control that no partial data has been written. * * MemBuffer is designed to handle relatively small data.

Over the years, the * poor performance of \link UFS UFS\endlink has become very obvious. In most * cases, \link UFS UFS\endlink limits Squid to about 30-50 requests per second. * Our work indicates that the poor performance is mostly * due to the synchronous nature of open() and unlink() * system calls, and perhaps thrashing of inode/buffer caches. * \par * We want to try out our own, customized filesystems with Squid. * In order to do that, we need a well-defined interface * for the bits of Squid that access the permanent storage * devices. We also require tighter control of the replacement * policy by each storage module, rather than a single global * replacement policy. * \section BuildStructure Build structure \par * The storage types live in \em src/fs/. Each subdirectory corresponds * to the name of the storage type. When a new storage type is implemented * configure.ac must be updated to autogenerate a Makefile in * \em src/fs/foo/ from a Makefile.in file. * \todo DOCS: add template addition to configure.ac for storage module addition. \todo DOCS: add template Makefile.am for storage module addition. * \par * configure will take a list of storage types through the * --enable-store-io parameter. This parameter takes a list of * space seperated storage types. For example, * --enable-store-io="ufs aufs" . * \par * Each storage type must create an archive file * in \em src/fs/foo/.a . This file is automatically linked into * squid at compile time. * \par * Each storage filesystem must inherit from StoreFileSystem and provide * all virtual function hooks for squid to operate with. * \section OperationOfStorageModules Operation of a Storage Module \par * Squid understands the concept of multiple diverse storage directories. * Each storage directory provides a caching object store, with object * storage, retrieval, indexing and replacement. * \par * Each open object has associated with it a storeIOState object. The * storeIOState object is used to record the state of the current * object. Each storeIOState can have a storage module specific data * structure containing information private to the storage module. * \par * Each SwapDir has the concept of a maximum object size.

/* NONCE CREATION - NOTES AND REASONING. RBC 20010108 * === EXCERPT FROM RFC 2617 === * The contents of the nonce are implementation dependent. The quality * of the implementation depends on a good choice. A nonce might, for * example, be constructed as the base 64 encoding of * * time-stamp H(time-stamp ":" ETag ":" private-key) * * where time-stamp is a server-generated time or other non-repeating * value, ETag is the value of the HTTP ETag header associated with * the requested entity, and private-key is data known only to the * server. With a nonce of this form a server would recalculate the * hash portion after receiving the client authentication header and * reject the request if it did not match the nonce from that header * or if the time-stamp value is not recent enough. In this way the * server can limit the time of the nonce's validity. The inclusion of * the ETag prevents a replay request for an updated version of the * resource. (Note: including the IP address of the client in the * nonce would appear to offer the server the ability to limit the * reuse of the nonce to the same client that originally got it. * However, that would break proxy farms, where requests from a single * user often go through different proxies in the farm. Also, IP * address spoofing is not that hard.) * ==== * * Now for my reasoning: * We will not accept a unrecognised nonce->we have all recognisable * nonces stored. If we send out unique base64 encodings we guarantee * that a given nonce applies to only one user (barring attacks or * really bad timing with expiry and creation). Using a random * component in the nonce allows us to loop to find a unique nonce. * We use H(nonce_data) so the nonce is meaningless to the reciever. * So our nonce looks like base64(H(timestamp,pointertohash,randomdata)) * And even if our randomness is not very random (probably due to * bad coding on my part) we don't really care - the timestamp and * memory pointer also guarantee local uniqueness in the input to the hash * function. */ /* create a new nonce */ newnonce->nc = 0; newnonce->flags.valid = true; newnonce->noncedata.self = newnonce; newnonce->noncedata.creationtime = current_time.tv_sec; newnonce->noncedata.randomdata = squid_random(); authDigestNonceEncode(newnonce); /* * loop until we get a unique nonce.

To address this all callback * functions make use of a construct called cbdata. This allows * functions doing callbacks to verify that the caller is still * valid before making the callback. * \note cbdata is intended for callback data and is tailored specifically * to make callbacks less dangerous leaving as few windows of errors as * possible. It is not suitable or intended as a generic RefCount * memory allocator. * \todo CODE: make cbdata a template or class-inheritance system instead of Macros. * \section Examples Examples \par * Here you can find some examples on how to use cbdata, and why. * \subsection AsyncOpWithoutCBDATA Asynchronous operation without cbdata, showing why cbdata is needed \par * For a asyncronous operation with callback functions, the normal * sequence of events in programs NOT using cbdata is as follows: * \code // initialization type_of_data our_data; ... our_data = malloc(...); ... // Initiate a asyncronous operation, with our_data as callback_data fooOperationStart(bar, callback_func, our_data); ... // The asyncronous operation completes and makes the callback callback_func(callback_data, ....); // Some time later we clean up our data free(our_data); \endcode * \par * However, things become more interesting if we want or need * to free the callback_data, or otherwise cancel the callback, * before the operation completes. In constructs like this you * can quite easily end up with having the memory referenced * pointed to by callback_data freed before the callback is invoked * causing a program failure or memory corruption: * \code // initialization type_of_data our_data; ... our_data = malloc(...); ... // Initiate a asyncronous operation, with our_data as callback_data fooOperationStart(bar, callback_func, our_data); ... // ouch, something bad happened elsewhere.. try to cleanup // but the programmer forgot there is a callback pending from // fooOperationsStart() (an easy thing to forget when writing code // to deal with errors, especially if there may be many different // pending operation) free(our_data); ... // The asyncronous operation completes and makes the callback callback_func(callback_data, ....); // CRASH, the memory pointer to by callback_data is no longer valid // at the time of the callback \endcode * \subsection AsyncOpWithCBDATA Asyncronous operation with cbdata * \par * The callback data allocator lets us do this in a uniform and * safe manner. The callback data allocator is used to allocate, * track and free memory pool objects used during callback * operations. Allocated memory is locked while the asyncronous * operation executes elsewhere, and is freed when the operation * completes. The normal sequence of events is: * \code // initialization type_of_data our_data; ... our_data = cbdataAlloc(type_of_data); ... // Initiate a asyncronous operation, with our_data as callback_data fooOperationStart(..., callback_func, our_data); ... // foo void *local_pointer = cbdataReference(callback_data); .... // The asyncronous operation completes and makes the callback void *cbdata; if (cbdataReferenceValidDone(local_pointer, &cbdata)) callback_func(...., cbdata); ... cbdataFree(our_data); \endcode * \subsection AsynchronousOpCancelledByCBDATA Asynchronous operation cancelled by cbdata * \par * With this scheme, nothing bad happens if cbdataFree() gets called * before fooOperantionComplete(...). * \par Initalization \code type_of_data our_data; ... our_data = cbdataAlloc(type_of_data); \endcode * Initiate a asyncronous operation, with our_data as callback_data \code fooOperationStart(..., callback_func, our_data); \endcode * do some stuff with it \code void *local_pointer = cbdataReference(callback_data); \endcode * something bad happened elsewhere.. cleanup \code cbdataFree(our_data); \endcode * The asyncronous operation completes and tries to make the callback \code void *cbdata; if (cbdataReferenceValidDone(local_pointer, &cbdata)) { \endcode * won't be called, as the data is no longer valid \code callback_func(...., cbdata); } \endcode * \par * In this case, when cbdataFree() is called before * cbdataReferenceValidDone(), the callback_data gets marked as invalid. * When the callback_data is invalid before executing the callback * function, cbdataReferenceValidDone() will return 0 and * callback_func is never executed. * \subsection AddingCBDATAType Adding a new cbdata registered type * \par * To add new module specific data types to the allocator one uses the * macros CBDATA_TYPE() and CBDATA_INIT_TYPE(). These creates a local cbdata * definition (file or block scope). Any cbdataAlloc() calls must be made * within this scope. However, cbdataFree() might be called from anywhere. * \par * First the cbdata type needs to be defined in the module. This * is usually done at file scope, but it can also be local to a * function or block.. \code CBDATA_TYPE(type_of_data); \endcode * Then in the code somewhere before the first allocation * (can be called multiple times with only a minimal overhead) \code CBDATA_INIT_TYPE(type_of_data); \endcode * Or if a free function is associated with the data type. This * function is responsible for cleaning up any dependencies etc * referenced by the structure and is called on cbdataFree() or * when the last reference is deleted by cbdataReferenceDone() / * cbdataReferenceValidDone() \code CBDATA_INIT_TYPE_FREECB(type_of_data, free_function); \endcode * \subsection AddingGlobalCBDATATypes Adding a new cbdata registered data type globally * \par * To add new global data types that can be allocated from anywhere * within the code one have to add them to the cbdata_type enum in * enums.h, and a corresponding CREATE_CBDATA() call in * cbdata.c:cbdataInit(). Or alternatively add a CBDATA_GLOBAL_TYPE() * definition to globals.h as shown below and use CBDATA_INIT_TYPE() at * the appropriate location(s) as described above. * \code extern CBDATA_GLOBAL_TYPE(type_of_data); // CBDATA_UNDEF \endcode */ /** *\ingroup CBDATAAPI * cbdata types.

This documentation can also be found online at: http://www.squid-cache.org/Doc/config/ You may wish to look at the Squid home page and wiki for the FAQ and other documentation: http://www.squid-cache.org/ http://wiki.squid-cache.org/SquidFaq http://wiki.squid-cache.org/ConfigExamples This documentation shows what the defaults for various directives happen to be. If you don't need to change the default, you should leave the line out of your squid.conf in most cases. In some cases "none" refers to no default setting at all, while in other cases it refers to the value of the option - the comments for that keyword indicate if this is the case. COMMENT_END COMMENT_START Configuration options can be included using the "include" directive. Include takes a list of files to include. Quoting and wildcards are supported. For example, include /path/to/included/file/squid.acl.config Includes can be nested up to a hard-coded depth of 16 levels. This arbitrary restriction is to prevent recursive include references from causing Squid entering an infinite loop whilst trying to load configuration files. Values with byte units Squid accepts size units on some size related directives. All such directives are documented with a default value displaying a unit. Units accepted by Squid are: bytes - byte KB - Kilobyte (1024 bytes) MB - Megabyte GB - Gigabyte Values with spaces, quotes, and other special characters Squid supports directive parameters with spaces, quotes, and other special characters. Surround such parameters with "double quotes". Use the configuration_includes_quoted_values directive to enable or disable that support. Squid supports reading configuration option parameters from external files using the syntax: parameters("/path/filename") For example: acl whitelist dstdomain parameters("/etc/squid/whitelist.txt") Conditional configuration If-statements can be used to make configuration directives depend on conditions: if ... regular configuration directives ... [else ... regular configuration directives ...] endif The else part is optional. The keywords "if", "else", and "endif" must be typed on their own lines, as if they were regular configuration directives. NOTE: An else-if condition is not supported. These individual conditions types are supported: true Always evaluates to true. false Always evaluates to false. = Equality comparison of two integer numbers. SMP-Related Macros The following SMP-related preprocessor macros can be used. ${process_name} expands to the current Squid process "name" (e.g., squid1, squid2, or cache1). ${process_number} expands to the current Squid process identifier, which is an integer number (e.g., 1, 2, 3) unique across all Squid processes of the current service instance. ${service_name} expands into the current Squid service instance name identifier which is provided by -n on the command line.

You might be safe using a larger value (e.g., 2 hours) in a corporate LAN environment with relatively static address assignments. DOC_END COMMENT_START ACCESS CONTROLS ----------------------------------------------------------------------------- COMMENT_END NAME: external_acl_type TYPE: externalAclHelper LOC: Config.externalAclHelperList DEFAULT: none DOC_START This option defines external acl classes using a helper program to look up the status external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..] Options: ttl=n TTL in seconds for cached results (defaults to 3600 for 1 hour) negative_ttl=n TTL for cached negative lookups (default same as ttl) grace=n Percentage remaining of TTL where a refresh of a cached entry should be initiated without needing to wait for a new reply. (default is for no grace period) cache=n Limit the result cache size, default is 262144. The expanded FORMAT value is used as the cache key, so if the details in FORMAT are highly variable a larger cache may be needed to produce reduction in helper load. children-max=n Maximum number of acl helper processes spawned to service external acl lookups of this type. (default 20) children-startup=n Minimum number of acl helper processes to spawn during startup and reconfigure to service external acl lookups of this type. (default 0) children-idle=n Number of acl helper processes to keep ahead of traffic loads. Squid will spawn this many at once whenever load rises above the capabilities of existing processes. Up to the value of children-max. (default 1) concurrency=n concurrency level per process. Only used with helpers capable of processing more than one query at a time. protocol=2.5 Compatibility mode for Squid-2.5 external acl helpers. ipv4 / ipv6 IP protocol used to communicate with this helper. The default is to auto-detect IPv6 and use it when available. FORMAT specifications %LOGIN Authenticated user login name %un A user name. Expands to the first available name from the following list of information sources: - authenticated user name, like %ul or %LOGIN - user name sent by an external ACL, like %EXT_USER - SSL client name, like %us in logformat - ident user name, like %ui in logformat %EXT_USER Username from previous external acl %EXT_LOG Log details from previous external acl %EXT_TAG Tag from previous external acl %IDENT Ident user name %SRC Client IP %SRCPORT Client source port %URI Requested URI %DST Requested host %PROTO Requested URL scheme %PORT Requested port %PATH Requested URL path %METHOD Request method %MYADDR Squid interface address %MYPORT Squid http_port number %PATH Requested URL-path (including query-string if any) %USER_CERT SSL User certificate in PEM format %USER_CERTCHAIN SSL User certificate chain in PEM format %USER_CERT_xx SSL User certificate subject attribute xx %USER_CA_CERT_xx SSL User certificate issuer attribute xx %ssl::>sni SSL client SNI sent to Squid %ssl::{Header} HTTP request header "Header" %>{Hdr:member} HTTP request header "Hdr" list member "member" %>{Hdr:;member} HTTP request header list member using ; as list separator. ; can be any non-alphanumeric character. %<{Header} HTTP reply header "Header" %<{Hdr:member} HTTP reply header "Hdr" list member "member" %<{Hdr:;member} HTTP reply header list member using ; as list separator. ; can be any non-alphanumeric character. %ACL The name of the ACL being tested. %DATA The ACL arguments. If not used then any arguments is automatically added at the end of the line sent to the helper. NOTE: this will encode the arguments as one token, whereas the default will pass each separately. %% The percent sign. Useful for helpers which need an unchanging input format. General request syntax: [channel-ID] FORMAT-values [acl-values ...] FORMAT-values consists of transaction details expanded with whitespace separation per the config file FORMAT specification using the FORMAT macros listed above. acl-values consists of any string specified in the referencing config 'acl ... external' line. see the "acl external" directive. Request values sent to the helper are URL escaped to protect each value in requests against whitespaces. If using protocol=2.5 then the request sent to the helper is not URL escaped to protect against whitespace. NOTE: protocol=3.0 is deprecated as no longer necessary. When using the concurrency= option the protocol is changed by introducing a query channel tag in front of the request/response. The query channel tag is a number between 0 and concurrency-1. This value must be echoed back unchanged to Squid as the first part of the response relating to its request. The helper receives lines expanded per the above format specification and for each input line returns 1 line starting with OK/ERR/BH result code and optionally followed by additional keywords with more details. General result syntax: [channel-ID] result keyword=value ... Result consists of one of the codes: OK the ACL test produced a match. ERR the ACL test does not produce a match. BH An internal error occurred in the helper, preventing a result being identified. The meaning of 'a match' is determined by your squid.conf access control configuration. See the Squid wiki for details. Defined keywords: user= The users name (login) password= The users password (for login= cache_peer option) message= Message describing the reason for this response. Available as %o in error pages. Useful on (ERR and BH results). tag= Apply a tag to a request. Only sets a tag once, does not alter existing tags. log= String to be logged in access.log. Available as %ea in logformat specifications. clt_conn_tag= Associates a TAG with the client TCP connection. Please see url_rewrite_program related documentation for this kv-pair. Any keywords may be sent on any response whether OK, ERR or BH. All response keyword values need to be a single token with URL escaping, or enclosed in double quotes (") and escaped using \ on any double quotes or \ characters within the value. The wrapping double quotes are removed before the value is interpreted by Squid. \r and \n are also replace by CR and LF.

DOC_START Defining an Access List Every access list definition must begin with an aclname and acltype, followed by either type-specific arguments or a quoted filename that they are read from. acl aclname acltype argument ... acl aclname acltype "file" ... When using "file", the file should contain one item per line. Some acl types supports options which changes their default behaviour. The available options are: -i,+i By default, regular expressions are CASE-SENSITIVE. To make them case-insensitive, use the -i option. To return case-sensitive use the +i option between patterns, or make a new ACL line without -i. -n Disable lookups and address type conversions. If lookup or conversion is required because the parameter type (IP or domain name) does not match the message address type (domain name or IP), then the ACL would immediately declare a mismatch without any warnings or lookups. -- Used to stop processing all options, in the case the first acl value has '-' character as first character (for example the '-' is a valid domain name) Some acl types require suspending the current request in order to access some external data source. Those which do are marked with the tag [slow], those which don't are marked as [fast].

Requests may pass through a chain of several other proxies before reaching us. The original source details may by sent in: * HTTP message Forwarded header, or * HTTP message X-Forwarded-For header, or * PROXY protocol connection header. This directive is solely for validating new PROXY protocol connections received from a port flagged with require-proxy-header. It is checked only once after TCP connection setup. A deny match results in TCP connection closure. An allow match is required for Squid to permit the corresponding TCP connection, before Squid even looks for HTTP request headers. If there is an allow match, Squid starts using PROXY header information to determine the source address of the connection for all future ACL checks, logging, etc. SECURITY CONSIDERATIONS: Any host from which we accept client IP details can place incorrect information in the relevant header, and Squid will use the incorrect information as if it were the source address of the request. This may enable remote hosts to bypass any access control restrictions that are based on the client's source addresses. This clause only supports fast acl types.

DOC_START Determine which client proxies can be trusted to provide correct information regarding real client IP address. Requests may pass through a chain of several other proxies before reaching us. The original source details may by sent in: * HTTP message Forwarded header, or * HTTP message X-Forwarded-For header, or * PROXY protocol connection header. PROXY protocol connections are controlled by the proxy_protocol_access directive which is checked before this. If a request reaches us from a source that is allowed by this directive, then we trust the information it provides regarding the IP of the client it received from (if any). For the purpose of ACLs used in this directive the src ACL type always matches the address we are testing and srcdomain matches its rDNS. On each HTTP request Squid checks for X-Forwarded-For header fields. If found the header values are iterated in reverse order and an allow match is required for Squid to continue on to the next value. The verification ends when a value receives a deny match, cannot be tested, or there are no more values to test. NOTE: Squid does not yet follow the Forwarded HTTP header. The end result of this process is an IP address that we will refer to as the indirect client address. This address may be treated as the client address for access control, ICAP, delay pools and logging, depending on the acl_uses_indirect_client, icap_uses_indirect_client, delay_pool_uses_indirect_client, log_uses_indirect_client and tproxy_uses_indirect_client options. This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. SECURITY CONSIDERATIONS: Any host from which we accept client IP details can place incorrect information in the relevant header, and Squid will use the incorrect information as if it were the source address of the request. This may enable remote hosts to bypass any access control restrictions that are based on the client's source addresses.

LOC: Config.ReplyBodySize DOC_START This option specifies the maximum size of a reply body. It can be used to prevent users from downloading very large files, such as MP3's and movies. When the reply headers are received, the reply_body_max_size lines are processed, and the first line where all (if any) listed ACLs are true is used as the maximum body size for this reply. This size is checked twice. First when we get the reply headers, we check the content-length value. If the content length value exists and is larger than the allowed size, the request is denied and the user receives an error message that says "the request or reply is too large." If there is no content-length, and the reply size exceeds this limit, the client's connection is just closed and they will receive a partial reply. WARNING: downstream caches probably can not detect a partial reply if there is no content-length header, so they will cache partial responses and give them out as hits. You should NOT use this option if you have downstream caches. WARNING: A maximum size smaller than the size of squid's error messages will cause an infinite loop and crash squid. Ensure that the smallest non-zero value you use is greater that the maximum header size plus the size of your largest error page.

You may specify multiple socket addresses. There are three forms: port alone, hostname with port, and IP address with port. If you specify a hostname or IP address, Squid binds the socket to that specific address. Most likely, you do not need to bind to a specific address, so you can use the port number alone. If you are running Squid in accelerator mode, you probably want to listen on port 80 also, or instead. The -a command line option may be used to specify additional port(s) where Squid listens for proxy request. Such ports will be plain proxy ports with no options. You may specify multiple socket addresses on multiple lines. Modes: intercept Support for IP-Layer NAT interception delivering traffic to this Squid port. NP: disables authentication on the port. tproxy Support Linux TPROXY (or BSD divert-to) with spoofing of outgoing connections using the client IP address.

DOC_END NAME: ftp_port TYPE: PortCfg DEFAULT: none LOC: FtpPortList DOC_START Enables Native FTP proxy by specifying the socket address where Squid listens for FTP client requests. See http_port directive for various ways to specify the listening address and mode. Usage: ftp_port address [mode] [options] WARNING: This is a new, experimental, complex feature that has seen limited production exposure. Some Squid modules (e.g., caching) do not currently work with native FTP proxying, and many features have not even been tested for compatibility. Test well before deploying! Native FTP proxying differs substantially from proxying HTTP requests with ftp:// URIs because Squid works as an FTP server and receives actual FTP commands (rather than HTTP requests with FTP URLs). Native FTP commands accepted at ftp_port are internally converted or wrapped into HTTP-like messages. The same happens to Native FTP responses received from FTP origin servers. Those HTTP-like messages are shoveled through regular access control and adaptation layers between the FTP client and the FTP origin server. This allows Squid to examine, adapt, block, and log FTP exchanges. Squid reuses most HTTP mechanisms when shoveling wrapped FTP messages. For example, http_access and adaptation_access directives are used. Modes: intercept Same as http_port intercept. The FTP origin address is determined based on the intended destination of the intercepted connection. tproxy Support Linux TPROXY for spoofing outgoing connections using the client IP address. NP: disables authentication and maybe IPv6 on the port. By default (i.e., without an explicit mode option), Squid extracts the FTP origin address from the login@origin parameter of the FTP USER command. Many popular FTP clients support such native FTP proxying. Options: name=token Specifies an internal name for the port. Defaults to the port address. Usable with myportname ACL. ftp-track-dirs Enables tracking of FTP directories by injecting extra PWD commands and adjusting Request-URI (in wrapping HTTP requests) to reflect the current FTP server directory. Tracking is disabled by default. protocol=FTP Protocol to reconstruct accelerated and intercepted requests with. Defaults to FTP. No other accepted values have been tested with. An unsupported value results in a FATAL error. Accepted values are FTP, HTTP (or HTTP/1.1), and HTTPS (or HTTPS/1.1). Other http_port modes and options that are not specific to HTTP and HTTPS may also work.

DOC_END NAME: tcp_outgoing_mark TYPE: acl_nfmark IFDEF: SO_MARK&&USE_LIBCAP DEFAULT: none LOC: Ip::Qos::TheConfig.nfmarkToServer DOC_START Allows you to apply a Netfilter mark value to outgoing packets on the server side, based on an ACL. tcp_outgoing_mark mark-value [!]aclname ...

DOC_END NAME: qos_flows TYPE: QosConfig IFDEF: USE_QOS_TOS DEFAULT: none LOC: Ip::Qos::TheConfig DOC_START Allows you to select a TOS/DSCP value to mark outgoing connections to the client, based on where the reply was sourced. For platforms using netfilter, allows you to set a netfilter mark value instead of, or in addition to, a TOS value. By default this functionality is disabled. To enable it with the default settings simply use "qos_flows mark" or "qos_flows tos". Default settings will result in the netfilter mark or TOS value being copied from the upstream connection to the client. Note that it is the connection CONNMARK value not the packet MARK value that is copied. It is not currently possible to copy the mark or TOS value from the client to the upstream connection request. TOS values really only have local significance - so you should know what you're specifying. For more information, see RFC2474, RFC2475, and RFC3260. The TOS/DSCP byte must be exactly that - a octet value 0 - 255. Note that only multiples of 4 are usable as the two rightmost bits have been redefined for use by ECN (RFC 3168 section 23.1). The squid parser will enforce this by masking away the ECN bits. Mark values can be any unsigned 32-bit integer value. This setting is configured by setting the following values: tos|mark Whether to set TOS or netfilter mark values local-hit=0xFF Value to mark local cache hits. sibling-hit=0xFF Value to mark hits from sibling peers. parent-hit=0xFF Value to mark hits from parent peers. miss=0xFF[/mask] Value to mark cache misses. Takes precedence over the preserve-miss feature (see below), unless mask is specified, in which case only the bits specified in the mask are written. The TOS variant of the following features are only possible on Linux and require your kernel to be patched with the TOS preserving ZPH patch, available from http://zph.bratcheda.org No patch is needed to preserve the netfilter mark, which will work with all variants of netfilter. disable-preserve-miss This option disables the preservation of the TOS or netfilter mark. By default, the existing TOS or netfilter mark value of the response coming from the remote server will be retained and masked with miss-mark. NOTE: in the case of a netfilter mark, the mark must be set on the connection (using the CONNMARK target) not on the packet (MARK target). miss-mask=0xFF Allows you to mask certain bits in the TOS or mark value received from the remote server, before copying the value to the TOS sent towards clients. Default for tos: 0xFF (TOS from server is not changed). Default for mark: 0xFFFFFFFF (mark from server is not changed). All of these features require the --enable-zph-qos compilation flag (enabled by default). Netfilter marking also requires the libnetfilter_conntrack libraries (--with-netfilter-conntrack) and libcap 2.09+ (--with-libcap). DOC_END NAME: tcp_outgoing_address TYPE: acl_address DEFAULT: none DEFAULT_DOC: Address selection is performed by the operating system. LOC: Config.accessList.outgoing_address DOC_START Allows you to map requests to different outgoing IP addresses based on the username or source address of the user making the request. tcp_outgoing_address ipaddr [[!]aclname] ... For example; Forwarding clients with dedicated IPs for certain subnets. acl normal_service_net src 10.0.0.0/24 acl good_service_net src 10.0.2.0/24 tcp_outgoing_address 2001:db8::c001 good_service_net tcp_outgoing_address 10.1.0.2 good_service_net tcp_outgoing_address 2001:db8::beef normal_service_net tcp_outgoing_address 10.1.0.1 normal_service_net tcp_outgoing_address 2001:db8::1 tcp_outgoing_address 10.1.0.3 Processing proceeds in the order specified, and stops at first fully matching line. Squid will add an implicit IP version test to each line. Requests going to IPv4 websites will use the outgoing 10.1.0.* addresses. Requests going to IPv6 websites will use the outgoing 2001:db8:* addresses. NOTE: The use of this directive using client dependent ACLs is incompatible with the use of server side persistent connections. To ensure correct results it is best to set server_persistent_connections to off when using this directive in such configurations. NOTE: The use of this directive to set a local IP on outgoing TCP links is incompatible with using TPROXY to set client IP out outbound TCP links. When needing to contact peers use the no-tproxy cache_peer option and the client_dst_passthru directive re-enable normal forwarding such as this. DOC_END NAME: host_verify_strict TYPE: onoff DEFAULT: off LOC: Config.onoff.hostStrictVerify DOC_START Regardless of this option setting, when dealing with intercepted traffic, Squid always verifies that the destination IP address matches the Host header domain or IP (called 'authority form URL'). This enforcement is performed to satisfy a MUST-level requirement in RFC 2616 section 14.23: "The Host field value MUST represent the naming authority of the origin server or gateway given by the original URL". When set to ON: Squid always responds with an HTTP 409 (Conflict) error page and logs a security warning if there is no match. Squid verifies that the destination IP address matches the Host header for forward-proxy and reverse-proxy traffic as well. For those traffic types, Squid also enables the following checks, comparing the corresponding Host header and Request-URI components: * The host names (domain or IP) must be identical, but valueless or missing Host header disables all checks. For the two host names to match, both must be either IP or FQDN. * Port numbers must be identical, but if a port is missing the scheme-default port is assumed. When set to OFF (the default): Squid allows suspicious requests to continue but logs a security warning and blocks caching of the response. * Forward-proxy traffic is not checked at all. * Reverse-proxy traffic is not checked at all. * Intercepted traffic which passes verification is handled according to client_dst_passthru. * Intercepted requests which fail verification are sent to the client original destination instead of DIRECT. This overrides 'client_dst_passthru off'. For now suspicious intercepted CONNECT requests are always responded to with an HTTP 409 (Conflict) error page. SECURITY NOTE: As described in CVE-2009-0801 when the Host: header alone is used to determine the destination of a request it becomes trivial for malicious scripts on remote websites to bypass browser same-origin security policy and sandboxing protections. The cause of this is that such applets are allowed to perform their own HTTP stack, in which case the same-origin policy of the browser sandbox only verifies that the applet tries to contact the same IP as from where it was loaded at the IP level. The Host: header may be different from the connected IP and approved origin. DOC_END NAME: client_dst_passthru TYPE: onoff DEFAULT: on LOC: Config.onoff.client_dst_passthru DOC_START With NAT or TPROXY intercepted traffic Squid may pass the request directly to the original client destination IP or seek a faster source using the HTTP Host header. Using Host to locate alternative servers can provide faster connectivity with a range of failure recovery options. But can also lead to connectivity trouble when the client and server are attempting stateful interactions unaware of the proxy. This option (on by default) prevents alternative DNS entries being located to send intercepted traffic DIRECT to an origin server. The clients original destination IP and port will be used instead. Regardless of this option setting, when dealing with intercepted traffic Squid will verify the Host: header and any traffic which fails Host verification will be treated as if this option were ON. see host_verify_strict for details on the verification process.

Peeking at the server certificate (during step 2) usually precludes bumping of the connection at step 3. stare Receive client (step SslBump1) or server (step SslBump2) certificate while preserving the possibility of bumping the connection. Staring at the server certificate (during step 2) usually precludes splicing of the connection at step 3. terminate Close client and server connections. Backward compatibility actions available at step SslBump1: client-first Bump the connection. Establish a secure connection with the client first, then connect to the server.

This is the default for trusted origin server certificates. signUntrusted Sign to guarantee an X509_V_ERR_CERT_UNTRUSTED browser error. This is the default for untrusted origin server certificates that are not self-signed (see ssl::certUntrusted). signSelf Sign using a self-signed certificate with the right CN to generate a X509_V_ERR_DEPTH_ZERO_SELF_SIGNED_CERT error in the browser. This is the default for self-signed origin server certificates (see ssl::certSelfSigned). This clause only supports fast acl types. When sslproxy_cert_sign acl(s) match, Squid uses the corresponding signing algorithm to generate the certificate and ignores all subsequent sslproxy_cert_sign options (the first match wins).

It is a misconfiguration to use setCommonName without an explicit parameter for intercepted or tproxied SSL connections. This clause only supports fast acl types. Squid first groups sslproxy_cert_adapt options by adaptation algorithm.

DOC_END COMMENT_START OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM ----------------------------------------------------------------------------- COMMENT_END NAME: cache_peer TYPE: peer DEFAULT: none LOC: Config.peers DOC_START To specify other caches in a hierarchy, use the format: cache_peer hostname type http-port icp-port [options] For example, # proxy icp # hostname type port port options # -------------------- -------- ----- ----- ----------- cache_peer parent.foo.net parent 3128 3130 default cache_peer sib1.foo.net sibling 3128 3130 proxy-only cache_peer sib2.foo.net sibling 3128 3130 proxy-only cache_peer example.com parent 80 0 default cache_peer cdn.example.com sibling 3128 0 type: either 'parent', 'sibling', or 'multicast'. proxy-port: The port number where the peer accept HTTP requests. For other Squid proxies this is usually 3128 For web servers this is usually 80 icp-port: Used for querying neighbor caches about objects. Set to 0 if the peer does not support ICP or HTCP. See ICP and HTCP options below for additional details. ==== ICP OPTIONS ==== You MUST also set icp_port and icp_access explicitly when using these options. The defaults will prevent peer traffic using ICP. no-query Disable ICP queries to this neighbor. multicast-responder Indicates the named peer is a member of a multicast group. ICP queries will not be sent directly to the peer, but ICP replies will be accepted from it. closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes. background-ping To only send ICP queries to this neighbor infrequently. This is used to keep the neighbor round trip time updated and is usually used in conjunction with weighted-round-robin. ==== HTCP OPTIONS ==== You MUST also set htcp_port and htcp_access explicitly when using these options. The defaults will prevent peer traffic using HTCP. htcp Send HTCP, instead of ICP, queries to the neighbor. You probably also want to set the "icp-port" to 4827 instead of 3130. This directive accepts a comma separated list of options described below. htcp=oldsquid Send HTCP to old Squid versions (2.5 or earlier). htcp=no-clr Send HTCP to the neighbor but without sending any CLR requests. This cannot be used with only-clr. htcp=only-clr Send HTCP to the neighbor but ONLY CLR requests. This cannot be used with no-clr. htcp=no-purge-clr Send HTCP to the neighbor including CLRs but only when they do not result from PURGE requests. htcp=forward-clr Forward any HTCP CLR requests this proxy receives to the peer. ==== PEER SELECTION METHODS ==== The default peer selection method is ICP, with the first responding peer being used as source. These options can be used for better load balancing. default This is a parent cache which can be used as a "last-resort" if a peer cannot be located by any of the peer-selection methods. If specified more than once, only the first is used. round-robin Load-Balance parents which should be used in a round-robin fashion in the absence of any ICP queries. weight=N can be used to add bias. weighted-round-robin Load-Balance parents which should be used in a round-robin fashion with the frequency of each parent being based on the round trip time. Closer parents are used more often. Usually used for background-ping parents. weight=N can be used to add bias. carp Load-Balance parents which should be used as a CARP array. The requests will be distributed among the parents based on the CARP load balancing hash function based on their weight. userhash Load-balance parents based on the client proxy_auth or ident username. sourcehash Load-balance parents based on the client source IP. multicast-siblings To be used only for cache peers of type "multicast". ALL members of this multicast group have "sibling" relationship with it, not "parent". This is to a multicast group when the requested object would be fetched only from a "parent" cache, anyway. It's useful, e.g., when configuring a pool of redundant Squid proxies, being members of the same multicast group. ==== PEER SELECTION OPTIONS ==== weight=N use to affect the selection of a peer during any weighted peer-selection mechanisms. The weight must be an integer; default is 1, larger weights are favored more. This option does not affect parent selection if a peering protocol is not in use. basetime=N Specify a base amount to be subtracted from round trip times of parents. It is subtracted before division by weight in calculating which parent to fectch from. If the rtt is less than the base time the rtt is set to a minimal value. ttl=N Specify a TTL to use when sending multicast ICP queries to this address. Only useful when sending to a multicast group. Because we don't accept ICP replies from random hosts, you must configure other group members as peers with the 'multicast-responder' option. no-delay To prevent access to this neighbor from influencing the delay pools. digest-url=URL Tell Squid to fetch the cache digest (if digests are enabled) for this host from the specified URL rather than the Squid default location. ==== CARP OPTIONS ==== carp-key=key-specification use a different key than the full URL to hash against the peer. the key-specification is a comma-separated list of the keywords scheme, host, port, path, params Order is not important. ==== ACCELERATOR / REVERSE-PROXY OPTIONS ==== originserver Causes this parent to be contacted as an origin server. Meant to be used in accelerator setups when the peer is a web server. forceddomain=name Set the Host header of requests forwarded to this peer. Useful in accelerator setups where the server (peer) expects a certain domain name but clients may request others. ie example.com or www.example.com no-digest Disable request of cache digests. no-netdb-exchange Disables requesting ICMP RTT database (NetDB). ==== AUTHENTICATION OPTIONS ==== login=user:password If this is a personal/workgroup proxy and your parent requires proxy authentication. Note: The string can include URL escapes (i.e. %20 for spaces). This also means % must be written as %%. login=PASSTHRU Send login details received from client to this peer. Both Proxy- and WWW-Authorization headers are passed without alteration to the peer. Authentication is not required by Squid for this to work. Note: This will pass any form of authentication but only Basic auth will work through a proxy unless the connection-auth options are also used. login=PASS Send login details received from client to this peer. Authentication is not required by this option. If there are no client-provided authentication headers to pass on, but username and password are available from an external ACL user= and password= result tags they may be sent instead. Note: To combine this with proxy_auth both proxies must share the same user database as HTTP only allows for a single login (one for proxy, one for origin server). Also be warned this will expose your users proxy password to the peer. USE WITH CAUTION login=*:password Send the username to the upstream cache, but with a fixed password. This is meant to be used when the peer is in another administrative domain, but it is still needed to identify each user. The star can optionally be followed by some extra information which is added to the username. This can be used to identify this proxy to the peer, similar to the login=username:password option above. login=NEGOTIATE If this is a personal/workgroup proxy and your parent requires a secure proxy authentication. The first principal from the default keytab or defined by the environment variable KRB5_KTNAME will be used. WARNING: The connection may transmit requests from multiple clients. Negotiate often assumes end-to-end authentication and a single-client. Which is not strictly true here. login=NEGOTIATE:principal_name If this is a personal/workgroup proxy and your parent requires a secure proxy authentication. The principal principal_name from the default keytab or defined by the environment variable KRB5_KTNAME will be used. WARNING: The connection may transmit requests from multiple clients. Negotiate often assumes end-to-end authentication and a single-client. Which is not strictly true here. connection-auth=on|off Tell Squid that this peer does or not support Microsoft connection oriented authentication, and any such challenges received from there should be ignored. Default is auto to automatically determine the status of the peer. ==== SSL / HTTPS / TLS OPTIONS ==== ssl Encrypt connections to this peer with SSL/TLS. sslcert=/path/to/ssl/certificate A client SSL certificate to use when connecting to this peer. sslkey=/path/to/ssl/key The private SSL key corresponding to sslcert above. If 'sslkey' is not specified 'sslcert' is assumed to reference a combined file containing both the certificate and the key. sslversion=1|2|3|4|5|6 The SSL version to use when connecting to this peer 1 = automatic (default) 2 = SSL v2 only 3 = SSL v3 only 4 = TLS v1.0 only 5 = TLS v1.1 only 6 = TLS v1.2 only sslcipher=... The list of valid SSL ciphers to use when connecting to this peer. ssloptions=...

See the OpenSSL SSL_CTX_set_options documentation for a more complete list. sslcafile=... A file containing additional CA certificates to use when verifying the peer certificate. sslcapath=... A directory containing additional CA certificates to use when verifying the peer certificate. sslcrlfile=... A certificate revocation list file to use when verifying the peer certificate. sslflags=... Specify various flags modifying the SSL implementation: DONT_VERIFY_PEER Accept certificates even if they fail to verify. NO_DEFAULT_CA Don't use the default CA list built in to OpenSSL. DONT_VERIFY_DOMAIN Don't verify the peer certificate matches the server name ssldomain= The peer name as advertised in it's certificate. Used for verifying the correctness of the received peer certificate. If not specified the peer hostname will be used. front-end-https Enable the "Front-End-Https: On" header needed when using Squid as a SSL frontend in front of Microsoft OWA. See MS KB document Q307347 for details on this header. If set to auto the header will only be added if the request is forwarded as a https:// URL. ==== GENERAL OPTIONS ==== connect-timeout=N A peer-specific connect timeout. Also see the peer_connect_timeout directive. connect-fail-limit=N How many times connecting to a peer must fail before it is marked as down. Standby connection failures count towards this limit. Default is 10. allow-miss Disable Squid's use of only-if-cached when forwarding requests to siblings. This is primarily useful when icp_hit_stale is used by the sibling. Excessive use of this option may result in forwarding loops. One way to prevent peering loops when using this option, is to deny cache peer usage on requests from a peer: acl fromPeer ... cache_peer_access peerName deny fromPeer max-conn=N Limit the number of concurrent connections the Squid may open to this peer, including already opened idle and standby connections. There is no peer-specific connection limit by default. A peer exceeding the limit is not used for new requests unless a standby connection is available. max-conn currently works poorly with idle persistent connections: When a peer reaches its max-conn limit, and there are idle persistent connections to the peer, the peer may not be selected because the limiting code does not know whether Squid can reuse those idle connections. standby=N Maintain a pool of N "hot standby" connections to an UP peer, available for requests when no idle persistent connection is available (or safe) to use. By default and with zero N, no such pool is maintained. N must not exceed the max-conn limit (if any). At start or after reconfiguration, Squid opens new TCP standby connections until there are N connections available and then replenishes the standby pool as opened connections are used up for requests. A used connection never goes back to the standby pool, but may go to the regular idle persistent connection pool shared by all peers and origin servers. Squid never opens multiple new standby connections concurrently. This one-at-a-time approach minimizes flooding-like effect on peers. Furthermore, just a few standby connections should be sufficient in most cases to supply most new requests with a ready-to-use connection. Standby connections obey server_idle_pconn_timeout. For the feature to work as intended, the peer must be configured to accept and keep them open longer than the idle timeout at the connecting Squid, to minimize race conditions typical to idle used persistent connections. Default request_timeout and server_idle_pconn_timeout values ensure such a configuration. name=xxx Unique name for the peer. Required if you have multiple peers on the same host but different ports. This name can be used in cache_peer_access and similar directives to identify the peer. Can be used by outgoing access controls through the peername ACL type. no-tproxy Do not use the client-spoof TPROXY support when forwarding requests to this peer. Use normal address selection instead. This overrides the spoof_client_ip ACL. proxy-only objects fetched from the peer will not be stored locally. DOC_END NAME: cache_peer_domain cache_host_domain TYPE: hostdomain DEFAULT: none LOC: none DOC_START Use to limit the domains for which a neighbor cache will be queried. Usage: cache_peer_domain cache-host domain [domain ...] cache_peer_domain cache-host !domain For example, specifying cache_peer_domain parent.foo.net .edu has the effect such that UDP query packets are sent to 'bigserver' only when the requested object exists on a server in the .edu domain. Prefixing the domainname with '!' means the cache will be queried for objects NOT in that domain. NOTE: * Any number of domains may be given for a cache-host, either on the same or separate lines. * When multiple domains are given for a particular cache-host, the first matched domain is applied. * Cache hosts with no domain restrictions are queried for all requests. * There are no defaults. * There is also a 'cache_peer_access' tag in the ACL section. DOC_END NAME: cache_peer_access TYPE: peer_access DEFAULT: none DEFAULT_DOC: No peer usage restrictions. LOC: none DOC_START Restricts usage of cache_peer proxies. Usage: cache_peer_access peer-name allow|deny [!]aclname ... For the required peer-name parameter, use either the value of the cache_peer name=value parameter or, if name=value is missing, the cache_peer hostname parameter. This directive narrows down the selection of peering candidates, but does not determine the order in which the selected candidates are contacted. That order is determined by the peer selection algorithms (see PEER SELECTION sections in the cache_peer documentation). If a deny rule matches, the corresponding peer will not be contacted for the current transaction -- Squid will not send ICP queries and will not forward HTTP requests to that peer. An allow match leaves the corresponding peer in the selection. The first match for a given peer wins for that peer. The relative order of cache_peer_access directives for the same peer matters. The relative order of any two cache_peer_access directives for different peers does not matter. To ease interpretation, it is a good idea to group cache_peer_access directives for the same peer together. A single cache_peer_access directive may be evaluated multiple times for a given transaction because individual peer selection algorithms may check it independently from each other. These redundant checks may be optimized away in future Squid versions. This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. DOC_END NAME: neighbor_type_domain TYPE: hostdomaintype DEFAULT: none DEFAULT_DOC: The peer type from cache_peer directive is used for all requests to that peer. LOC: none DOC_START Modify the cache_peer neighbor type when passing requests about specific domains to the peer. Usage: neighbor_type_domain neighbor parent|sibling domain domain ... For example: cache_peer foo.example.com parent 3128 3130 neighbor_type_domain foo.example.com sibling .au .de The above configuration treats all requests to foo.example.com as a parent proxy unless the request is for a .au or .de ccTLD domain name. DOC_END NAME: dead_peer_timeout COMMENT: (seconds) DEFAULT: 10 seconds TYPE: time_t LOC: Config.Timeout.deadPeer DOC_START This controls how long Squid waits to declare a peer cache as "dead." If there are no ICP replies received in this amount of time, Squid will declare the peer dead and not expect to receive any further ICP replies. However, it continues to send ICP queries, and will mark the peer as alive upon receipt of the first subsequent ICP reply. This timeout also affects when Squid expects to receive ICP replies from peers. If more than 'dead_peer' seconds have passed since the last ICP reply was received, Squid will not expect to receive an ICP reply on the next query. Thus, if your time between requests is greater than this timeout, you will see a lot of requests sent DIRECT to origin servers instead of to your parents. DOC_END NAME: forward_max_tries DEFAULT: 25 TYPE: int LOC: Config.forward_max_tries DOC_START Controls how many different forward paths Squid will try before giving up. See also forward_timeout. NOTE: connect_retries (default: none) can make each of these possible forwarding paths be tried multiple times. DOC_END COMMENT_START MEMORY CACHE OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: cache_mem COMMENT: (bytes) TYPE: b_size_t DEFAULT: 256 MB LOC: Config.memMaxSize DOC_START NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE. IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS. 'cache_mem' specifies the ideal amount of memory to be used for: * In-Transit objects * Hot Objects * Negative-Cached objects Data for these objects are stored in 4 KB blocks. This parameter specifies the ideal upper limit on the total size of 4 KB blocks allocated. In-Transit objects take the highest priority. In-transit objects have priority over the others. When additional space is needed for incoming data, negative-cached and hot objects will be released. In other words, the negative-cached and hot objects will fill up any unused space not needed for in-transit objects. If circumstances require, this limit will be exceeded. Specifically, if your incoming request rate requires more than 'cache_mem' of memory to hold in-transit objects, Squid will exceed this limit to satisfy the new requests. When the load decreases, blocks will be freed until the high-water mark is reached. Thereafter, blocks will be used to store hot objects. If shared memory caching is enabled, Squid does not use the shared cache space for in-transit objects, but they still consume as much local memory as they need. For more details about the shared memory cache, see memory_cache_shared. DOC_END NAME: maximum_object_size_in_memory COMMENT: (bytes) TYPE: b_size_t DEFAULT: 512 KB LOC: Config.Store.maxInMemObjSize DOC_START Objects greater than this size will not be attempted to kept in the memory cache. This should be set high enough to keep objects accessed frequently in memory to improve performance whilst low enough to keep larger objects from hoarding cache_mem. DOC_END NAME: memory_cache_shared COMMENT: on|off TYPE: YesNoNone LOC: Config.memShared DEFAULT: none DEFAULT_DOC: "on" where supported if doing memory caching with multiple SMP workers. DOC_START Controls whether the memory cache is shared among SMP workers. The shared memory cache is meant to occupy cache_mem bytes and replace the non-shared memory cache, although some entities may still be cached locally by workers for now (e.g., internal and in-transit objects may be served from a local memory cache even if shared memory caching is enabled). By default, the memory cache is shared if and only if all of the following conditions are satisfied: Squid runs in SMP mode with multiple workers, cache_mem is positive, and Squid environment supports required IPC primitives (e.g., POSIX shared memory segments and GCC-style atomic operations). To avoid blocking locks, shared memory uses opportunistic algorithms that do not guarantee that every cachable entity that could have been shared among SMP workers will actually be shared. Currently, entities exceeding 32KB in size cannot be shared. DOC_END NAME: memory_cache_mode TYPE: memcachemode LOC: Config DEFAULT: always DEFAULT_DOC: Keep the most recently fetched objects in memory DOC_START Controls which objects to keep in the memory cache (cache_mem) always Keep most recently fetched objects in memory (default) disk Only disk cache hits are kept in memory, which means an object must first be cached on disk and then hit a second time before cached in memory. network Only objects fetched from network is kept in memory DOC_END NAME: memory_replacement_policy TYPE: removalpolicy LOC: Config.memPolicy DEFAULT: lru DOC_START The memory replacement policy parameter determines which objects are purged from memory when memory space is needed. See cache_replacement_policy for details on algorithms. DOC_END COMMENT_START DISK CACHE OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: cache_replacement_policy TYPE: removalpolicy LOC: Config.replPolicy DEFAULT: lru DOC_START The cache replacement policy parameter determines which objects are evicted (replaced) when disk space is needed. lru : Squid's original list based LRU policy heap GDSF : Greedy-Dual Size Frequency heap LFUDA: Least Frequently Used with Dynamic Aging heap LRU : LRU policy implemented using a heap Applies to any cache_dir lines listed below this directive. The LRU policies keeps recently referenced objects. The heap GDSF policy optimizes object hit rate by keeping smaller popular objects in cache so it has a better chance of getting a hit. It achieves a lower byte hit rate than LFUDA though since it evicts larger (possibly popular) objects. The heap LFUDA policy keeps popular objects in cache regardless of their size and thus optimizes byte hit rate at the expense of hit rate since one large, popular object will prevent many smaller, slightly less popular objects from being cached. Both policies utilize a dynamic aging mechanism that prevents cache pollution that can otherwise occur with frequency-based replacement policies. NOTE: if using the LFUDA replacement policy you should increase the value of maximum_object_size above its default of 4 MB to to maximize the potential byte hit rate improvement of LFUDA. For more information about the GDSF and LFUDA cache replacement policies see http://www.hpl.hp.com/techreports/1999/HPL-1999-69.html and http://fog.hpl.external.hp.com/techreports/98/HPL-98-173.html. DOC_END NAME: minimum_object_size COMMENT: (bytes) TYPE: b_int64_t DEFAULT: 0 KB DEFAULT_DOC: no limit LOC: Config.Store.minObjectSize DOC_START Objects smaller than this size will NOT be saved on disk. The value is specified in bytes, and the default is 0 KB, which means all responses can be stored. DOC_END NAME: maximum_object_size COMMENT: (bytes) TYPE: b_int64_t DEFAULT: 4 MB LOC: Config.Store.maxObjectSize DOC_START Set the default value for max-size parameter on any cache_dir. The value is specified in bytes, and the default is 4 MB. If you wish to get a high BYTES hit ratio, you should probably increase this (one 32 MB object hit counts for 3200 10KB hits). If you wish to increase hit ratio more than you want to save bandwidth you should leave this low. NOTE: if using the LFUDA replacement policy you should increase this value to maximize the byte hit rate improvement of LFUDA! See cache_replacement_policy for a discussion of this policy. DOC_END NAME: cache_dir TYPE: cachedir DEFAULT: none DEFAULT_DOC: No disk cache. Store cache ojects only in memory. LOC: Config.cacheSwap DOC_START Format: cache_dir Type Directory-Name Fs-specific-data [options] You can specify multiple cache_dir lines to spread the cache among different disk partitions. Type specifies the kind of storage system to use. Only "ufs" is built by default. To enable any of the other storage systems see the --enable-storeio configure option. 'Directory' is a top-level directory where cache swap files will be stored. If you want to use an entire disk for caching, this can be the mount-point directory. The directory must exist and be writable by the Squid process. Squid will NOT create this directory for you. In SMP configurations, cache_dir must not precede the workers option and should use configuration macros or conditionals to give each worker interested in disk caching a dedicated cache directory. ==== The ufs store type ==== "ufs" is the old well-known Squid storage format that has always been there. Usage: cache_dir ufs Directory-Name Mbytes L1 L2 [options] 'Mbytes' is the amount of disk space (MB) to use under this directory. The default is 100 MB. Change this to suit your configuration. Do NOT put the size of your disk drive here. Instead, if you want Squid to use the entire disk drive, subtract 20% and use that value. 'L1' is the number of first-level subdirectories which will be created under the 'Directory'. The default is 16. 'L2' is the number of second-level subdirectories which will be created under each first-level directory. The default is 256. ==== The aufs store type ==== "aufs" uses the same storage format as "ufs", utilizing POSIX-threads to avoid blocking the main Squid process on disk-I/O. This was formerly known in Squid as async-io. Usage: cache_dir aufs Directory-Name Mbytes L1 L2 [options] see argument descriptions under ufs above ==== The diskd store type ==== "diskd" uses the same storage format as "ufs", utilizing a separate process to avoid blocking the main Squid process on disk-I/O. Usage: cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n] see argument descriptions under ufs above Q1 specifies the number of unacknowledged I/O requests when Squid stops opening new files. If this many messages are in the queues, Squid won't open new files. Default is 64 Q2 specifies the number of unacknowledged messages when Squid starts blocking. If this many messages are in the queues, Squid blocks until it receives some replies. Default is 72 When Q1 < Q2 (the default), the cache directory is optimized for lower response time at the expense of a decrease in hit ratio. If Q1 > Q2, the cache directory is optimized for higher hit ratio at the expense of an increase in response time. ==== The rock store type ==== Usage: cache_dir rock Directory-Name Mbytes [options] The Rock Store type is a database-style storage. All cached entries are stored in a "database" file, using fixed-size slots. A single entry occupies one or more slots. If possible, Squid using Rock Store creates a dedicated kid process called "disker" to avoid blocking Squid worker(s) on disk I/O. One disker kid is created for each rock cache_dir. Diskers are created only when Squid, running in daemon mode, has support for the IpcIo disk I/O module. swap-timeout=msec: Squid will not start writing a miss to or reading a hit from disk if it estimates that the swap operation will take more than the specified number of milliseconds. By default and when set to zero, disables the disk I/O time limit enforcement. Ignored when using blocking I/O module because blocking synchronous I/O does not allow Squid to estimate the expected swap wait time. max-swap-rate=swaps/sec: Artificially limits disk access using the specified I/O rate limit. Swap out requests that would cause the average I/O rate to exceed the limit are delayed. Individual swap in requests (i.e., hits or reads) are not delayed, but they do contribute to measured swap rate and since they are placed in the same FIFO queue as swap out requests, they may wait longer if max-swap-rate is smaller. This is necessary on file systems that buffer "too many" writes and then start blocking Squid and other processes while committing those writes to disk. Usually used together with swap-timeout to avoid excessive delays and queue overflows when disk demand exceeds available disk "bandwidth". By default and when set to zero, disables the disk I/O rate limit enforcement. Currently supported by IpcIo module only. slot-size=bytes: The size of a database "record" used for storing cached responses. A cached response occupies at least one slot and all database I/O is done using individual slots so increasing this parameter leads to more disk space waste while decreasing it leads to more disk I/O overheads. Should be a multiple of your operating system I/O page size. Defaults to 16KBytes. A housekeeping header is stored with each slot and smaller slot-sizes will be rejected. The header is smaller than 100 bytes. ==== COMMON OPTIONS ==== no-store no new objects should be stored to this cache_dir. min-size=n the minimum object size in bytes this cache_dir will accept. It's used to restrict a cache_dir to only store large objects (e.g. AUFS) while other stores are optimized for smaller objects (e.g. Rock). Defaults to 0. max-size=n the maximum object size in bytes this cache_dir supports. The value in maximum_object_size directive sets the default unless more specific details are available (ie a small store capacity). Note: To make optimal use of the max-size limits you should order the cache_dir lines with the smallest max-size value first. NOCOMMENT_START # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs @DEFAULT_SWAP_DIR@ 100 16 256 NOCOMMENT_END DOC_END NAME: store_dir_select_algorithm TYPE: string LOC: Config.store_dir_select_algorithm DEFAULT: least-load DOC_START How Squid selects which cache_dir to use when the response object will fit into more than one. Regardless of which algorithm is used the cache_dir min-size and max-size parameters are obeyed. As such they can affect the selection algorithm by limiting the set of considered cache_dir. Algorithms: least-load This algorithm is suited to caches with similar cache_dir sizes and disk speeds. The disk with the least I/O pending is selected. When there are multiple disks with the same I/O load ranking the cache_dir with most available capacity is selected. When a mix of cache_dir sizes are configured the faster disks have a naturally lower I/O loading and larger disks have more capacity. So space used to store objects and data throughput may be very unbalanced towards larger disks. round-robin This algorithm is suited to caches with unequal cache_dir disk sizes. Each cache_dir is selected in a rotation. The next suitable cache_dir is used. Available cache_dir capacity is only considered in relation to whether the object will fit and meets the min-size and max-size parameters. Disk I/O loading is only considered to prevent overload on slow disks. This algorithm does not spread objects by size, so any I/O loading per-disk may appear very unbalanced and volatile. If several cache_dirs use similar min-size, max-size, or other limits to to reject certain responses, then do not group such cache_dir lines together, to avoid round-robin selection bias towards the first cache_dir after the group. Instead, interleave cache_dir lines from different groups. For example: store_dir_select_algorithm round-robin cache_dir rock /hdd1 ... min-size=100000 cache_dir rock /ssd1 ... max-size=99999 cache_dir rock /hdd2 ... min-size=100000 cache_dir rock /ssd2 ... max-size=99999 cache_dir rock /hdd3 ... min-size=100000 cache_dir rock /ssd3 ... max-size=99999 DOC_END NAME: max_open_disk_fds TYPE: int LOC: Config.max_open_disk_fds DEFAULT: 0 DEFAULT_DOC: no limit DOC_START To avoid having disk as the I/O bottleneck Squid can optionally bypass the on-disk cache if more than this amount of disk file descriptors are open. A value of 0 indicates no limit. DOC_END NAME: cache_swap_low COMMENT: (percent, 0-100) TYPE: int DEFAULT: 90 LOC: Config.Swap.lowWaterMark DOC_START The low-water mark for AUFS/UFS/diskd cache object eviction by the cache_replacement_policy algorithm. Removal begins when the swap (disk) usage of a cache_dir is above this low-water mark and attempts to maintain utilization near the low-water mark. As swap utilization increases towards the high-water mark set by cache_swap_high object eviction becomes more agressive. The value difference in percentages between low- and high-water marks represent an eviction rate of 300 objects per second and the rate continues to scale in agressiveness by multiples of this above the high-water mark. Defaults are 90% and 95%. If you have a large cache, 5% could be hundreds of MB. If this is the case you may wish to set these numbers closer together. See also cache_swap_high and cache_replacement_policy DOC_END NAME: cache_swap_high COMMENT: (percent, 0-100) TYPE: int DEFAULT: 95 LOC: Config.Swap.highWaterMark DOC_START The high-water mark for AUFS/UFS/diskd cache object eviction by the cache_replacement_policy algorithm. Removal begins when the swap (disk) usage of a cache_dir is above the low-water mark set by cache_swap_low and attempts to maintain utilization near the low-water mark. As swap utilization increases towards this high-water mark object eviction becomes more agressive. The value difference in percentages between low- and high-water marks represent an eviction rate of 300 objects per second and the rate continues to scale in agressiveness by multiples of this above the high-water mark.

DOC_START Usage: logformat Defines an access log format. The is a string with embedded % format codes % format codes all follow the same basic structure where all but the formatcode is optional. Output strings are automatically escaped as required according to their context and the output format modifiers are usually not needed, but can be specified if an explicit output format is desired. % ["|[|'|#] [-] [[0]width] [{argument}] formatcode " output in quoted string format [ output in squid text log format as used by log_mime_hdrs # output in URL quoted format ' output as-is - left aligned width minimum and/or maximum field width: [width_min][.width_max] When minimum starts with 0, the field is zero-padded. String values exceeding maximum width are truncated. {arg} argument such as header name etc Format codes: % a literal % character sn Unique sequence number per log line entry err_code The ID of an error response served by Squid or a similar internal error identifier. err_detail Additional err_code-dependent error information. note The annotation specified by the argument. Also logs the adaptation meta headers set by the adaptation_meta configuration parameter. If no argument given all annotations logged. The argument may include a separator to use with annotation values: name[:separator] By default, multiple note values are separated with "," and multiple notes are separated with "\r\n". When logging named notes with %{name}note, the explicitly configured separator is used between note values. When logging all notes with %note, the explicitly configured separator is used between individual notes. There is currently no way to specify both value and notes separators when logging all notes with %note. Connection related format codes: >a Client source IP address >A Client FQDN >p Client source port >eui Client source EUI (MAC address, EUI-48 or EUI-64 identifier) >la Local IP address the client connected to >lp Local port number the client connected to >qos Client connection TOS/DSCP value set by Squid >nfmark Client connection netfilter mark set by Squid la Local listening IP address the client connection was connected to. lp Local listening port number the client connection was connected to. . format. Currently, Squid considers the master transaction started when a complete HTTP request header initiating the transaction is received from the client. This is the same value that Squid uses to calculate transaction response time when logging %tr to access.log. Currently, Squid uses millisecond resolution for %tS values, similar to the default access.log "current time" field (%ts.%03tu). Access Control related format codes: et Tag returned by external acl ea Log string returned by external acl un User name (any available) ul User name from authentication ue User name from external acl helper ui User name from ident un A user name. Expands to the first available name from the following list of information sources: - authenticated user name, like %ul - user name supplied by an external ACL, like %ue - SSL client name, like %us - ident user name, like %ui credentials Client credentials. The exact meaning depends on the authentication scheme: For Basic authentication, it is the password; for Digest, the realm sent by the client; for NTLM and Negotiate, the client challenge or client credentials prefixed with "YR " or "KK ". HTTP related format codes: REQUEST [http::]rm Request method (GET/POST etc) [http::]>rm Request method from client [http::]ru Request URL from client [http::]rs Request URL scheme from client [http::]rd Request URL domain from client [http::]rP Request URL port from client [http::]rp Request URL path excluding hostname from client [http::]rv Request protocol version from client [http::]h Original received request header. Usually differs from the request header sent by Squid, although most fields are often preserved. Accepts optional header field name/value filter argument using name[:[separator]element] format. [http::]>ha Received request header after adaptation and redirection (pre-cache REQMOD vectoring point). Usually differs from the request header sent by Squid, although most fields are often preserved. Optional header name argument as for >h RESPONSE [http::]Hs HTTP status code sent to the client [http::]h [http::]mt MIME content type SIZE COUNTERS [http::]st Total size of request + reply traffic with client [http::]>st Total size of request received from client. Excluding chunked encoding bytes. [http::]sh Size of request headers received from client [http::]sni SSL client SNI sent to Squid. Available only after the peek, stare, or splice SSL bumping actions. If ICAP is enabled, the following code becomes available (as well as ICAP log codes documented with the icap_log option): icap::tt Total ICAP processing time for the HTTP transaction. The timer ticks when ICAP ACLs are checked and when ICAP transaction is in progress. If adaptation is enabled the following three codes become available: adapt::cert_subject The Subject field of the received client SSL certificate or a dash ('-') if Squid has received an invalid/malformed certificate or no certificate at all. Consider encoding the logged value because Subject often has spaces. %ssl::>cert_issuer The Issuer field of the received client SSL certificate or a dash ('-') if Squid has received an invalid/malformed certificate or no certificate at all. Consider encoding the logged value because Issuer often has spaces. The default formats available (which do not need re-defining) are: logformat squid %ts.%03tu %6tr %>a %Ss/%03>Hs %a %[ui %[un [%tl] "%rm %ru HTTP/%rv" %>Hs %a %[ui %[un [%tl] "%rm %ru HTTP/%rv" %>Hs %h" "%{User-Agent}>h" %Ss:%Sh logformat referrer %ts.%03tu %>a %{Referer}>h %ru logformat useragent %>a [%tl] "%{User-Agent}>h" NOTE: When the log_mime_hdrs directive is set to ON. The squid, common and combined formats have a safely encoded copy of the mime headers appended to each line within a pair of brackets. NOTE: The common and combined formats are not quite true to the Apache definition. The logs from Squid contain an extra status and hierarchy code appended. DOC_END NAME: access_log cache_access_log TYPE: access_log LOC: Config.Log.accesslogs DEFAULT_IF_NONE: daemon:@DEFAULT_ACCESS_LOG@ squid DOC_START Configures whether and how Squid logs HTTP and ICP transactions. If access logging is enabled, a single line is logged for every matching HTTP or ICP request. The recommended directive formats are: access_log : [option ...] [acl acl ...] access_log none [acl acl ...] The following directive format is accepted but may be deprecated: access_log : [ [acl acl ...]] In most cases, the first ACL name must not contain the '=' character and should not be equal to an existing logformat name. You can always start with an 'all' ACL to work around those restrictions. Will log to the specified module:place using the specified format (which must be defined in a logformat directive) those entries which match ALL the acl's specified (which must be defined in acl clauses). If no acl is specified, all requests will be logged to this destination. ===== Available options for the recommended directive format ===== logformat=name Names log line format (either built-in or defined by a logformat directive). Defaults to 'squid'. buffer-size=64KB Defines approximate buffering limit for log records (see buffered_logs). Squid should not keep more than the specified size and, hence, should flush records before the buffer becomes full to avoid overflows under normal conditions (the exact flushing algorithm is module-dependent though). The on-error option controls overflow handling. on-error=die|drop Defines action on unrecoverable errors. The 'drop' action ignores (i.e., does not log) affected log records. The default 'die' action kills the affected worker. The drop action support has not been tested for modules other than tcp. ===== Modules Currently available ===== none Do not log any requests matching these ACL. Do not specify Place or logformat name. stdio Write each log line to disk immediately at the completion of each request. Place: the filename and path to be written. daemon Very similar to stdio. But instead of writing to disk the log line is passed to a daemon helper for asychronous handling instead. Place: varies depending on the daemon. log_file_daemon Place: the file name and path to be written. syslog To log each request via syslog facility. Place: The syslog facility and priority level for these entries. Place Format: facility.priority where facility could be any of: authpriv, daemon, local0 ... local7 or user. And priority could be any of: err, warning, notice, info, debug. udp To send each log line as text data to a UDP receiver. Place: The destination host name or IP and port. Place Format: //host:port tcp To send each log line as text data to a TCP receiver. Lines may be accumulated before sending (see buffered_logs). Place: The destination host name or IP and port. Place Format: //host:port Default: access_log daemon:@DEFAULT_ACCESS_LOG@ squid DOC_END NAME: icap_log TYPE: access_log IFDEF: ICAP_CLIENT LOC: Config.Log.icaplogs DEFAULT: none DOC_START ICAP log files record ICAP transaction summaries, one line per transaction. The icap_log option format is: icap_log [ [acl acl ...]] icap_log none [acl acl ...]] Please see access_log option documentation for details. The two kinds of logs share the overall configuration approach and many features. ICAP processing of a single HTTP message or transaction may require multiple ICAP transactions. In such cases, multiple ICAP transaction log lines will correspond to a single access log line. ICAP log uses logformat codes that make sense for an ICAP transaction. Header-related codes are applied to the HTTP header embedded in an ICAP server response, with the following caveats: For REQMOD, there is no HTTP response header unless the ICAP server performed request satisfaction. For RESPMOD, the HTTP request header is the header sent to the ICAP server. For OPTIONS, there are no HTTP headers. The following format codes are also available for ICAP logs: icap::st Bytes sent to the ICAP server (TCP payload only; i.e., what Squid writes to the socket). icap::h ICAP request header(s). Similar to >h. icap::a %icap::to/%03icap::Hs %icap::\n - logfile data R\n - rotate file T\n - truncate file O\n - reopen file F\n - flush file r\n - set rotate count to b\n - 1 = buffer output, 0 = don't buffer output No responses is expected. DOC_END NAME: stats_collection TYPE: acl_access LOC: Config.accessList.stats_collection DEFAULT: none DEFAULT_DOC: Allow logging for all transactions. COMMENT: allow|deny acl acl... DOC_START This options allows you to control which requests gets accounted in performance counters. This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. DOC_END NAME: cache_store_log TYPE: string DEFAULT: none LOC: Config.Log.store DOC_START Logs the activities of the storage manager. Shows which objects are ejected from the cache, and which objects are saved and for how long. There are not really utilities to analyze this data, so you can safely disable it (the default). Store log uses modular logging outputs. See access_log for the list of modules supported. Example: cache_store_log stdio:@DEFAULT_STORE_LOG@ cache_store_log daemon:@DEFAULT_STORE_LOG@ DOC_END NAME: cache_swap_state cache_swap_log TYPE: string LOC: Config.Log.swap DEFAULT: none DEFAULT_DOC: Store the journal inside its cache_dir DOC_START Location for the cache "swap.state" file. This index file holds the metadata of objects saved on disk. It is used to rebuild the cache during startup. Normally this file resides in each 'cache_dir' directory, but you may specify an alternate pathname here. Note you must give a full filename, not just a directory. Since this is the index for the whole object list you CANNOT periodically rotate it! If %s can be used in the file name it will be replaced with a a representation of the cache_dir name where each / is replaced with '.'. This is needed to allow adding/removing cache_dir lines when cache_swap_log is being used. If have more than one 'cache_dir', and %s is not used in the name these swap logs will have names such as: cache_swap_log.00 cache_swap_log.01 cache_swap_log.02 The numbered extension (which is added automatically) corresponds to the order of the 'cache_dir' lines in this configuration file. If you change the order of the 'cache_dir' lines in this file, these index files will NOT correspond to the correct 'cache_dir' entry (unless you manually rename them). We recommend you do NOT use this option. It is better to keep these index files in each 'cache_dir' directory. DOC_END NAME: logfile_rotate TYPE: int DEFAULT: 10 LOC: Config.Log.rotateNumber DOC_START Specifies the number of logfile rotations to make when you type 'squid -k rotate'. The default is 10, which will rotate with extensions 0 through 9. Setting logfile_rotate to 0 will disable the file name rotation, but the logfiles are still closed and re-opened. This will enable you to rename the logfiles yourself just before sending the rotate signal. Note, the 'squid -k rotate' command normally sends a USR1 signal to the running squid process. In certain situations (e.g. on Linux with Async I/O), USR1 is used for other purposes, so -k rotate uses another signal. It is best to get in the habit of using 'squid -k rotate' instead of 'kill -USR1 '. Note, from Squid-3.1 this option is only a default for cache.log, that log can be rotated separately by using debug_options. DOC_END NAME: mime_table TYPE: string DEFAULT: @DEFAULT_MIME_TABLE@ LOC: Config.mimeTablePathname DOC_START Path to Squid's icon configuration file. You shouldn't need to change this, but the default file contains examples and formatting information if you do. DOC_END NAME: log_mime_hdrs COMMENT: on|off TYPE: onoff LOC: Config.onoff.log_mime_hdrs DEFAULT: off DOC_START The Cache can record both the request and the response MIME headers for each HTTP transaction. The headers are encoded safely and will appear as two bracketed fields at the end of the access log (for either the native or httpd-emulated log formats). To enable this logging set log_mime_hdrs to 'on'. DOC_END NAME: pid_filename TYPE: string DEFAULT: @DEFAULT_PID_FILE@ LOC: Config.pidFilename DOC_START A filename to write the process-id to. To disable, enter "none". DOC_END NAME: client_netmask TYPE: address LOC: Config.Addrs.client_netmask DEFAULT: no_addr DEFAULT_DOC: Log full client IP address DOC_START A netmask for client addresses in logfiles and cachemgr output. Change this to protect the privacy of your cache clients. A netmask of 255.255.255.0 will log all IP's in that range with the last digit set to '0'. DOC_END NAME: strip_query_terms TYPE: onoff LOC: Config.onoff.strip_query_terms DEFAULT: on DOC_START By default, Squid strips query terms from requested URLs before logging. This protects your user's privacy and reduces log size. When investigating HIT/MISS or other caching behaviour you will need to disable this to see the full URL used by Squid. DOC_END NAME: buffered_logs COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.buffered_logs DOC_START Whether to write/send access_log records ASAP or accumulate them and then write/send them in larger chunks. Buffering may improve performance because it decreases the number of I/Os. However, buffering increases the delay before log records become available to the final recipient (e.g., a disk file or logging daemon) and, hence, increases the risk of log records loss. Note that even when buffered_logs are off, Squid may have to buffer records if it cannot write/send them immediately due to pending I/Os (e.g., the I/O writing the previous log record) or connectivity loss. Currently honored by 'daemon' and 'tcp' access_log modules only. DOC_END NAME: netdb_filename TYPE: string DEFAULT: stdio:@DEFAULT_NETDB_FILE@ LOC: Config.netdbFilename IFDEF: USE_ICMP DOC_START Where Squid stores it's netdb journal. When enabled this journal preserves netdb state between restarts. To disable, enter "none". DOC_END COMMENT_START OPTIONS FOR TROUBLESHOOTING ----------------------------------------------------------------------------- COMMENT_END NAME: cache_log TYPE: string DEFAULT_IF_NONE: @DEFAULT_CACHE_LOG@ LOC: Debug::cache_log DOC_START Squid administrative logging file. This is where general information about Squid behavior goes. You can increase the amount of data logged to this file and how often it is rotated with "debug_options" DOC_END NAME: debug_options TYPE: eol DEFAULT: ALL,1 DEFAULT_DOC: Log all critical and important messages. LOC: Debug::debugOptions DOC_START Logging options are set as section,level where each source file is assigned a unique section. Lower levels result in less output, Full debugging (level 9) can result in a very large log file, so be careful. The magic word "ALL" sets debugging levels for all sections. The default is to run with "ALL,1" to record important warnings. The rotate=N option can be used to keep more or less of these logs than would otherwise be kept by logfile_rotate. For most uses a single log should be enough to monitor current events affecting Squid. DOC_END NAME: coredump_dir TYPE: string LOC: Config.coredump_dir DEFAULT_IF_NONE: none DEFAULT_DOC: Use the directory from where Squid was started. DOC_START By default Squid leaves core files in the directory from where it was started. If you set 'coredump_dir' to a directory that exists, Squid will chdir() to that directory at startup and coredump files will be left there. NOCOMMENT_START # Leave coredumps in the first cache dir coredump_dir @DEFAULT_SWAP_DIR@ NOCOMMENT_END DOC_END COMMENT_START OPTIONS FOR FTP GATEWAYING ----------------------------------------------------------------------------- COMMENT_END NAME: ftp_user TYPE: string DEFAULT: Squid@ LOC: Config.Ftp.anon_user DOC_START If you want the anonymous login password to be more informative (and enable the use of picky FTP servers), set this to something reasonable for your domain, like wwwuser@somewhere.net The reason why this is domainless by default is the request can be made on the behalf of a user in any domain, depending on how the cache is used. Some FTP server also validate the email address is valid (for example perl.com). DOC_END NAME: ftp_passive TYPE: onoff DEFAULT: on LOC: Config.Ftp.passive DOC_START If your firewall does not allow Squid to use passive connections, turn off this option. Use of ftp_epsv_all option requires this to be ON. DOC_END NAME: ftp_epsv_all TYPE: onoff DEFAULT: off LOC: Config.Ftp.epsv_all DOC_START FTP Protocol extensions permit the use of a special "EPSV ALL" command. NATs may be able to put the connection on a "fast path" through the translator, as the EPRT command will never be used and therefore, translation of the data portion of the segments will never be needed. When a client only expects to do two-way FTP transfers this may be useful. If squid finds that it must do a three-way FTP transfer after issuing an EPSV ALL command, the FTP session will fail. If you have any doubts about this option do not use it. Squid will nicely attempt all other connection methods. Requires ftp_passive to be ON (default) for any effect. DOC_END NAME: ftp_epsv TYPE: ftp_epsv DEFAULT: none LOC: Config.accessList.ftp_epsv DOC_START FTP Protocol extensions permit the use of a special "EPSV" command. NATs may be able to put the connection on a "fast path" through the translator using EPSV, as the EPRT command will never be used and therefore, translation of the data portion of the segments will never be needed. EPSV is often required to interoperate with FTP servers on IPv6 networks. On the other hand, it may break some IPv4 servers. By default, EPSV may try EPSV with any FTP server. To fine tune that decision, you may restrict EPSV to certain clients or servers using ACLs: ftp_epsv allow|deny al1 acl2 ... WARNING: Disabling EPSV may cause problems with external NAT and IPv6. Only fast ACLs are supported. Requires ftp_passive to be ON (default) for any effect. DOC_END NAME: ftp_eprt TYPE: onoff DEFAULT: on LOC: Config.Ftp.eprt DOC_START FTP Protocol extensions permit the use of a special "EPRT" command. This extension provides a protocol neutral alternative to the IPv4-only PORT command. When supported it enables active FTP data channels over IPv6 and efficient NAT handling. Turning this OFF will prevent EPRT being attempted and will skip straight to using PORT for IPv4 servers. Some devices are known to not handle this extension correctly and may result in crashes. Devices which suport EPRT enough to fail cleanly will result in Squid attempting PORT anyway. This directive should only be disabled when EPRT results in device failures. WARNING: Doing so will convert Squid back to the old behavior with all the related problems with external NAT devices/layers and IPv4-only FTP. DOC_END NAME: ftp_sanitycheck TYPE: onoff DEFAULT: on LOC: Config.Ftp.sanitycheck DOC_START For security and data integrity reasons Squid by default performs sanity checks of the addresses of FTP data connections ensure the data connection is to the requested server. If you need to allow FTP connections to servers using another IP address for the data connection turn this off. DOC_END NAME: ftp_telnet_protocol TYPE: onoff DEFAULT: on LOC: Config.Ftp.telnet DOC_START The FTP protocol is officially defined to use the telnet protocol as transport channel for the control connection. However, many implementations are broken and does not respect this aspect of the FTP protocol. If you have trouble accessing files with ASCII code 255 in the path or similar problems involving this ASCII code you can try setting this directive to off. If that helps, report to the operator of the FTP server in question that their FTP server is broken and does not follow the FTP standard. DOC_END COMMENT_START OPTIONS FOR EXTERNAL SUPPORT PROGRAMS ----------------------------------------------------------------------------- COMMENT_END NAME: diskd_program TYPE: string DEFAULT: @DEFAULT_DISKD@ LOC: Config.Program.diskd DOC_START Specify the location of the diskd executable.

DOC_END COMMENT_START OPTIONS FOR URL REWRITING ----------------------------------------------------------------------------- COMMENT_END NAME: url_rewrite_program redirect_program TYPE: wordlist LOC: Config.Program.redirect DEFAULT: none DOC_START Specify the location of the executable URL rewriter to use. Since they can perform almost any function there isn't one included. For each requested URL, the rewriter will receive on line with the format [channel-ID ] URL [ extras] See url_rewrite_extras on how to send "extras" with optional values to the helper. After processing the request the helper must reply using the following format: [channel-ID ] result [ kv-pairs] The result code can be: OK status=30N url="..." Redirect the URL to the one supplied in 'url='. 'status=' is optional and contains the status code to send the client in Squids HTTP response. It must be one of the HTTP redirect status codes: 301, 302, 303, 307, 308. When no status is given Squid will use 302. OK rewrite-url="..." Rewrite the URL to the one supplied in 'rewrite-url='. The new URL is fetched directly by Squid and returned to the client as the response to its request. OK When neither of url= and rewrite-url= are sent Squid does not change the URL. ERR Do not change the URL. BH An internal error occurred in the helper, preventing a result being identified. The 'message=' key name is reserved for delivering a log message. In addition to the above kv-pairs Squid also understands the following optional kv-pairs received from URL rewriters: clt_conn_tag=TAG Associates a TAG with the client TCP connection. The TAG is treated as a regular annotation but persists across future requests on the client connection rather than just the current request. A helper may update the TAG during subsequent requests be returning a new kv-pair. When using the concurrency= option the protocol is changed by introducing a query channel tag in front of the request/response. The query channel tag is a number between 0 and concurrency-1. This value must be echoed back unchanged to Squid as the first part of the response relating to its request. WARNING: URL re-writing ability should be avoided whenever possible. Use the URL redirect form of response instead. Re-write creates a difference in the state held by the client and server. Possibly causing confusion when the server response contains snippets of its view state. Embeded URLs, response and content Location headers, etc. are not re-written by this interface. By default, a URL rewriter is not used. DOC_END NAME: url_rewrite_children redirect_children TYPE: HelperChildConfig DEFAULT: 20 startup=0 idle=1 concurrency=0 LOC: Config.redirectChildren DOC_START The maximum number of redirector processes to spawn. If you limit it too few Squid will have to wait for them to process a backlog of URLs, slowing it down. If you allow too many they will use RAM and other system resources noticably. The startup= and idle= options allow some measure of skew in your tuning. startup= Sets a minimum of how many processes are to be spawned when Squid starts or reconfigures. When set to zero the first request will cause spawning of the first child process to handle it. Starting too few will cause an initial slowdown in traffic as Squid attempts to simultaneously spawn enough processes to cope. idle= Sets a minimum of how many processes Squid is to try and keep available at all times. When traffic begins to rise above what the existing processes can handle this many more will be spawned up to the maximum configured. A minimum setting of 1 is required. concurrency= The number of requests each redirector helper can handle in parallel. Defaults to 0 which indicates the redirector is a old-style single threaded redirector. When this directive is set to a value >= 1 then the protocol used to communicate with the helper is modified to include an ID in front of the request/response. The ID from the request must be echoed back with the response to that request. DOC_END NAME: url_rewrite_host_header redirect_rewrites_host_header TYPE: onoff DEFAULT: on LOC: Config.onoff.redir_rewrites_host DOC_START To preserve same-origin security policies in browsers and prevent Host: header forgery by redirectors Squid rewrites any Host: header in redirected requests. If you are running an accelerator this may not be a wanted effect of a redirector. This directive enables you disable Host: alteration in reverse-proxy traffic. WARNING: Entries are cached on the result of the URL rewriting process, so be careful if you have domain-virtual hosts.

Use the StoreID supplied in 'store-id='. ERR The default is to use HTTP request URL as the store ID. BH An internal error occured in the helper, preventing a result being identified. In addition to the above kv-pairs Squid also understands the following optional kv-pairs received from URL rewriters: clt_conn_tag=TAG Associates a TAG with the client TCP connection. Please see url_rewrite_program related documentation for this kv-pair Helper programs should be prepared to receive and possibly ignore additional whitespace-separated tokens on each input line. When using the concurrency= option the protocol is changed by introducing a query channel tag in front of the request/response. The query channel tag is a number between 0 and concurrency-1. This value must be echoed back unchanged to Squid as the first part of the response relating to its request. NOTE: when using StoreID refresh_pattern will apply to the StoreID returned from the helper and not the URL.

DOC_END COMMENT_START OPTIONS FOR TUNING THE CACHE ----------------------------------------------------------------------------- COMMENT_END NAME: cache no_cache TYPE: acl_access DEFAULT: none DEFAULT_DOC: By default, this directive is unused and has no effect. LOC: Config.accessList.noCache DOC_START Requests denied by this directive will not be served from the cache and their responses will not be stored in the cache. This directive has no effect on other transactions and on already cached responses. This clause supports both fast and slow acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. This and the two other similar caching directives listed below are checked at different transaction processing stages, have different access to response information, affect different cache operations, and differ in slow ACLs support: * cache: Checked before Squid makes a hit/miss determination. No access to reply information! Denies both serving a hit and storing a miss. Supports both fast and slow ACLs. * send_hit: Checked after a hit was detected. Has access to reply (hit) information. Denies serving a hit only. Supports fast ACLs only. * store_miss: Checked before storing a cachable miss. Has access to reply (miss) information. Denies storing a miss only. Supports fast ACLs only. If you are not sure which of the three directives to use, apply the following decision logic: * If your ACL(s) are of slow type _and_ need response info, redesign. Squid does not support that particular combination at this time. Otherwise: * If your directive ACL(s) are of slow type, use "cache"; and/or * if your directive ACL(s) need no response info, use "cache". Otherwise: * If you do not want the response cached, use store_miss; and/or * if you do not want a hit on a cached response, use send_hit. DOC_END NAME: send_hit TYPE: acl_access DEFAULT: none DEFAULT_DOC: By default, this directive is unused and has no effect. LOC: Config.accessList.sendHit DOC_START Responses denied by this directive will not be served from the cache (but may still be cached, see store_miss). This directive has no effect on the responses it allows and on the cached objects. Please see the "cache" directive for a summary of differences among store_miss, send_hit, and cache directives. Unlike the "cache" directive, send_hit only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. For example: # apply custom Store ID mapping to some URLs acl MapMe dstdomain .c.example.com store_id_program ... store_id_access allow MapMe # but prevent caching of special responses # such as 302 redirects that cause StoreID loops acl Ordinary http_status 200-299 store_miss deny MapMe !Ordinary # and do not serve any previously stored special responses # from the cache (in case they were already cached before # the above store_miss rule was in effect). send_hit deny MapMe !Ordinary DOC_END NAME: store_miss TYPE: acl_access DEFAULT: none DEFAULT_DOC: By default, this directive is unused and has no effect. LOC: Config.accessList.storeMiss DOC_START Responses denied by this directive will not be cached (but may still be served from the cache, see send_hit). This directive has no effect on the responses it allows and on the already cached responses. Please see the "cache" directive for a summary of differences among store_miss, send_hit, and cache directives. See the send_hit directive for a usage example.

DOC_END NAME: max_stale COMMENT: time-units TYPE: time_t LOC: Config.maxStale DEFAULT: 1 week DOC_START This option puts an upper limit on how stale content Squid will serve from the cache if cache validation fails. Can be overriden by the refresh_pattern max-stale option. DOC_END NAME: refresh_pattern TYPE: refreshpattern LOC: Config.Refresh DEFAULT: none DOC_START usage: refresh_pattern [-i] regex min percent max [options] By default, regular expressions are CASE-SENSITIVE. To make them case-insensitive, use the -i option. 'Min' is the time (in minutes) an object without an explicit expiry time should be considered fresh. The recommended value is 0, any higher values may cause dynamic applications to be erroneously cached unless the application designer has taken the appropriate actions. 'Percent' is a percentage of the objects age (time since last modification age) an object without explicit expiry time will be considered fresh. 'Max' is an upper limit on how long objects without an explicit expiry time will be considered fresh. options: override-expire override-lastmod reload-into-ims ignore-reload ignore-no-store ignore-must-revalidate ignore-private ignore-auth max-stale=NN refresh-ims store-stale override-expire enforces min age even if the server sent an explicit expiry time (e.g., with the Expires: header or Cache-Control: max-age). Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. Note: override-expire does not enforce staleness - it only extends freshness / min. If the server returns a Expires time which is longer than your max time, Squid will still consider the object fresh for that period of time. override-lastmod enforces min age even on objects that were modified recently. reload-into-ims changes a client no-cache or ``reload'' request for a cached entry into a conditional request using If-Modified-Since and/or If-None-Match headers, provided the cached entry has a Last-Modified and/or a strong ETag header. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. ignore-reload ignores a client no-cache or ``reload'' header. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. ignore-no-store ignores any ``Cache-control: no-store'' headers received from a server. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. ignore-must-revalidate ignores any ``Cache-Control: must-revalidate`` headers received from a server. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. ignore-private ignores any ``Cache-control: private'' headers received from a server. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. ignore-auth caches responses to requests with authorization, as if the originserver had sent ``Cache-control: public'' in the response header. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. refresh-ims causes squid to contact the origin server when a client issues an If-Modified-Since request. This ensures that the client will receive an updated version if one is available. store-stale stores responses even if they don't have explicit freshness or a validator (i.e., Last-Modified or an ETag) present, or if they're already stale. By default, Squid will not cache such responses because they usually can't be reused. Note that such responses will be stale by default. max-stale=NN provide a maximum staleness factor. Squid won't serve objects more stale than this even if it failed to validate the object. Default: use the max_stale global limit. Basically a cached object is: FRESH if expire > now, else STALE STALE if age > max FRESH if lm-factor < percent, else STALE FRESH if age < min else STALE The refresh_pattern lines are checked in the order listed here. The first entry which matches is used. If none of the entries match the default will be used. Note, you must uncomment all the default lines if you want to change one.

This may be undesirable on slow (e.g. SLIP) links and/or very busy caches. Impatient users may tie up file descriptors and bandwidth by repeatedly requesting and immediately aborting downloads. When the user aborts a request, Squid will check the quick_abort values to the amount of data transferred until then. If the transfer has less than 'quick_abort_min' KB remaining, it will finish the retrieval. If the transfer has more than 'quick_abort_max' KB remaining, it will abort the retrieval. If more than 'quick_abort_pct' of the transfer has completed, it will finish the retrieval. If you do not want any retrieval to continue after the client has aborted, set both 'quick_abort_min' and 'quick_abort_max' to '0 KB'. If you want retrievals to always continue if they are being cached set 'quick_abort_min' to '-1 KB'. DOC_END NAME: read_ahead_gap COMMENT: buffer-size TYPE: b_int64_t LOC: Config.readAheadGap DEFAULT: 16 KB DOC_START The amount of data the cache will buffer ahead of what has been sent to the client when retrieving an object from another server. DOC_END NAME: negative_ttl IFDEF: USE_HTTP_VIOLATIONS COMMENT: time-units TYPE: time_t LOC: Config.negativeTtl DEFAULT: 0 seconds DOC_START Set the Default Time-to-Live (TTL) for failed requests. Certain types of failures (such as "connection refused" and "404 Not Found") are able to be negatively-cached for a short time. Modern web servers should provide Expires: header, however if they do not this can provide a minimum TTL. The default is not to cache errors with unknown expiry details. Note that this is different from negative caching of DNS lookups. WARNING: Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. DOC_END NAME: positive_dns_ttl COMMENT: time-units TYPE: time_t LOC: Config.positiveDnsTtl DEFAULT: 6 hours DOC_START Upper limit on how long Squid will cache positive DNS responses. Default is 6 hours (360 minutes). This directive must be set larger than negative_dns_ttl. DOC_END NAME: negative_dns_ttl COMMENT: time-units TYPE: time_t LOC: Config.negativeDnsTtl DEFAULT: 1 minutes DOC_START Time-to-Live (TTL) for negative caching of failed DNS lookups. This also sets the lower cache limit on positive lookups. Minimum value is 1 second, and it is not recommendable to go much below 10 seconds. DOC_END NAME: range_offset_limit COMMENT: size [acl acl...] TYPE: acl_b_size_t LOC: Config.rangeOffsetLimit DEFAULT: none DOC_START usage: (size) [units] [[!]aclname] Sets an upper limit on how far (number of bytes) into the file a Range request may be to cause Squid to prefetch the whole file. If beyond this limit, Squid forwards the Range request as it is and the result is NOT cached. This is to stop a far ahead range request (lets say start at 17MB) from making Squid fetch the whole object up to that point before sending anything to the client. Multiple range_offset_limit lines may be specified, and they will be searched from top to bottom on each request until a match is found. The first match found will be used. If no line matches a request, the default limit of 0 bytes will be used. 'size' is the limit specified as a number of units. 'units' specifies whether to use bytes, KB, MB, etc. If no units are specified bytes are assumed. A size of 0 causes Squid to never fetch more than the client requested. (default) A size of 'none' causes Squid to always fetch the object from the beginning so it may cache the result. (2.0 style) 'aclname' is the name of a defined ACL. NP: Using 'none' as the byte value here will override any quick_abort settings that may otherwise apply to the range request. The range request will be fully fetched from start to finish regardless of the client actions. This affects bandwidth usage. DOC_END NAME: minimum_expiry_time COMMENT: (seconds) TYPE: time_t LOC: Config.minimum_expiry_time DEFAULT: 60 seconds DOC_START The minimum caching time according to (Expires - Date) headers Squid honors if the object can't be revalidated. The default is 60 seconds. In reverse proxy environments it might be desirable to honor shorter object lifetimes. It is most likely better to make your server return a meaningful Last-Modified header however. In ESI environments where page fragments often have short lifetimes, this will often be best set to 0. DOC_END NAME: store_avg_object_size COMMENT: (bytes) TYPE: b_int64_t DEFAULT: 13 KB LOC: Config.Store.avgObjectSize DOC_START Average object size, used to estimate number of objects your cache can hold. The default is 13 KB. This is used to pre-seed the cache index memory allocation to reduce expensive reallocate operations while handling clients traffic. Too-large values may result in memory allocation during peak traffic, too-small values will result in wasted memory. Check the cache manager 'info' report metrics for the real object sizes seen by your Squid before tuning this. DOC_END NAME: store_objects_per_bucket TYPE: int DEFAULT: 20 LOC: Config.Store.objectsPerBucket DOC_START Target number of objects per bucket in the store hash table. Lowering this value increases the total number of buckets and also the storage maintenance rate. The default is 20. DOC_END COMMENT_START HTTP OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: request_header_max_size COMMENT: (KB) TYPE: b_size_t DEFAULT: 64 KB LOC: Config.maxRequestHeaderSize DOC_START This specifies the maximum size for HTTP headers in a request. Request headers are usually relatively small (about 512 bytes). Placing a limit on the request header size will catch certain bugs (for example with persistent connections) and possibly buffer-overflow or denial-of-service attacks. DOC_END NAME: reply_header_max_size COMMENT: (KB) TYPE: b_size_t DEFAULT: 64 KB LOC: Config.maxReplyHeaderSize DOC_START This specifies the maximum size for HTTP headers in a reply. Reply headers are usually relatively small (about 512 bytes). Placing a limit on the reply header size will catch certain bugs (for example with persistent connections) and possibly buffer-overflow or denial-of-service attacks. DOC_END NAME: request_body_max_size COMMENT: (bytes) TYPE: b_int64_t DEFAULT: 0 KB DEFAULT_DOC: No limit. LOC: Config.maxRequestBodySize DOC_START This specifies the maximum size for an HTTP request body. In other words, the maximum size of a PUT/POST request. A user who attempts to send a request with a body larger than this limit receives an "Invalid Request" error message. If you set this parameter to a zero (the default), there will be no limit imposed. See also client_request_buffer_max_size for an alternative limitation on client uploads which can be configured. DOC_END NAME: client_request_buffer_max_size COMMENT: (bytes) TYPE: b_size_t DEFAULT: 512 KB LOC: Config.maxRequestBufferSize DOC_START This specifies the maximum buffer size of a client request. It prevents squid eating too much memory when somebody uploads a large file. DOC_END NAME: broken_posts IFDEF: USE_HTTP_VIOLATIONS TYPE: acl_access DEFAULT: none DEFAULT_DOC: Obey RFC 2616. LOC: Config.accessList.brokenPosts DOC_START A list of ACL elements which, if matched, causes Squid to send an extra CRLF pair after the body of a PUT/POST request. Some HTTP servers has broken implementations of PUT/POST, and rely on an extra CRLF pair sent by some WWW clients. Quote from RFC2616 section 4.1 on this matter: Note: certain buggy HTTP/1.0 client implementations generate an extra CRLF's after a POST request. To restate what is explicitly forbidden by the BNF, an HTTP/1.1 client must not preface or follow a request with an extra CRLF. This clause only supports fast acl types.

DOC_END NAME: ie_refresh COMMENT: on|off TYPE: onoff LOC: Config.onoff.ie_refresh DEFAULT: off DOC_START Microsoft Internet Explorer up until version 5.5 Service Pack 1 has an issue with transparent proxies, wherein it is impossible to force a refresh. Turning this on provides a partial fix to the problem, by causing all IMS-REFRESH requests from older IE versions to check the origin server for fresh content. This reduces hit ratio by some amount (~10% in my experience), but allows users to actually get fresh content when they want it. Note because Squid cannot tell if the user is using 5.5 or 5.5SP1, the behavior of 5.5 is unchanged from old versions of Squid (i.e. a forced refresh is impossible). Newer versions of IE will, hopefully, continue to have the new behavior and will be handled based on that assumption. This option defaults to the old Squid behavior, which is better for hit ratios but worse for clients using IE, if they need to be able to force fresh content. DOC_END NAME: vary_ignore_expire COMMENT: on|off TYPE: onoff LOC: Config.onoff.vary_ignore_expire DEFAULT: off DOC_START Many HTTP servers supporting Vary gives such objects immediate expiry time with no cache-control header when requested by a HTTP/1.0 client. This option enables Squid to ignore such expiry times until HTTP/1.1 is fully implemented. WARNING: If turned on this may eventually cause some varying objects not intended for caching to get cached. DOC_END NAME: request_entities TYPE: onoff LOC: Config.onoff.request_entities DEFAULT: off DOC_START Squid defaults to deny GET and HEAD requests with request entities, as the meaning of such requests are undefined in the HTTP standard even if not explicitly forbidden. Set this directive to on if you have clients which insists on sending request entities in GET or HEAD requests. But be warned that there is server software (both proxies and web servers) which can fail to properly process this kind of request which may make you vulnerable to cache pollution attacks if enabled. DOC_END NAME: request_header_access IFDEF: USE_HTTP_VIOLATIONS TYPE: http_header_access LOC: Config.request_header_access DEFAULT: none DEFAULT_DOC: No limits. DOC_START Usage: request_header_access header_name allow|deny [!]aclname ... WARNING: Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. This option replaces the old 'anonymize_headers' and the older 'http_anonymizer' option with something that is much more configurable. A list of ACLs for each header name allows removal of specific header fields under specific conditions. This option only applies to outgoing HTTP request headers (i.e., headers sent by Squid to the next HTTP hop such as a cache peer or an origin server). The option has no effect during cache hit detection. The equivalent adaptation vectoring point in ICAP terminology is post-cache REQMOD. The option is applied to individual outgoing request header fields. For each request header field F, Squid uses the first qualifying sets of request_header_access rules: 1. Rules with header_name equal to F's name. 2. Rules with header_name 'Other', provided F's name is not on the hard-coded list of commonly used HTTP header names. 3. Rules with header_name 'All'. Within that qualifying rule set, rule ACLs are checked as usual. If ACLs of an "allow" rule match, the header field is allowed to go through as is. If ACLs of a "deny" rule match, the header is removed and request_header_replace is then checked to identify if the removed header has a replacement. If no rules within the set have matching ACLs, the header field is left as is. For example, to achieve the same behavior as the old 'http_anonymizer standard' option, you should use: request_header_access From deny all request_header_access Referer deny all request_header_access User-Agent deny all Or, to reproduce the old 'http_anonymizer paranoid' feature you should use: request_header_access Authorization allow all request_header_access Proxy-Authorization allow all request_header_access Cache-Control allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Connection allow all request_header_access All deny all HTTP reply headers are controlled with the reply_header_access directive.

This option only applies to reply headers, i.e., from the server to the client. This is the same as request_header_access, but in the other direction. Please see request_header_access for detailed documentation.

DOC_END NAME: request_header_add TYPE: HeaderWithAclList LOC: Config.request_header_add DEFAULT: none DOC_START Usage: request_header_add field-name field-value acl1 [acl2] ... Example: request_header_add X-Client-CA "CA=%ssl::>cert_issuer" all This option adds header fields to outgoing HTTP requests (i.e., request headers sent by Squid to the next HTTP hop such as a cache peer or an origin server). The option has no effect during cache hit detection. The equivalent adaptation vectoring point in ICAP terminology is post-cache REQMOD. Field-name is a token specifying an HTTP header name. If a standard HTTP header name is used, Squid does not check whether the new header conflicts with any existing headers or violates HTTP rules. If the request to be modified already contains a field with the same name, the old field is preserved but the header field values are not merged. Field-value is either a token or a quoted string. If quoted string format is used, then the surrounding quotes are removed while escape sequences and %macros are processed. In theory, all of the logformat codes can be used as %macros. However, unlike logging (which happens at the very end of transaction lifetime), the transaction may not yet have enough information to expand a macro when the new header value is needed. And some information may already be available to Squid but not yet committed where the macro expansion code can access it (report such instances!). The macro will be expanded into a single dash ('-') in such cases. Not all macros have been tested. One or more Squid ACLs may be specified to restrict header injection to matching requests. As always in squid.conf, all ACLs in an option ACL list must be satisfied for the insertion to happen. The request_header_add option supports fast ACLs only. DOC_END NAME: note TYPE: note LOC: Config.notes DEFAULT: none DOC_START This option used to log custom information about the master transaction. For example, an admin may configure Squid to log which "user group" the transaction belongs to, where "user group" will be determined based on a set of ACLs and not [just] authentication information. Values of key/value pairs can be logged using %{key}note macros: note key value acl ... logformat myFormat ... %{key}note ... DOC_END NAME: relaxed_header_parser COMMENT: on|off|warn TYPE: tristate LOC: Config.onoff.relaxed_header_parser DEFAULT: on DOC_START In the default "on" setting Squid accepts certain forms of non-compliant HTTP messages where it is unambiguous what the sending application intended even if the message is not correctly formatted. The messages is then normalized to the correct form when forwarded by Squid. If set to "warn" then a warning will be emitted in cache.log each time such HTTP error is encountered. If set to "off" then such HTTP errors will cause the request or response to be rejected. DOC_END NAME: collapsed_forwarding COMMENT: (on|off) TYPE: onoff LOC: Config.onoff.collapsed_forwarding DEFAULT: off DOC_START This option controls whether Squid is allowed to merge multiple potentially cachable requests for the same URI before Squid knows whether the response is going to be cachable. This feature is disabled by default: Enabling collapsed forwarding needlessly delays forwarding requests that look cachable (when they are collapsed) but then need to be forwarded individually anyway because they end up being for uncachable content. However, in some cases, such as accelleration of highly cachable content with periodic or groupped expiration times, the gains from collapsing [large volumes of simultenous refresh requests] outweigh losses from such delays. DOC_END COMMENT_START TIMEOUTS ----------------------------------------------------------------------------- COMMENT_END NAME: forward_timeout COMMENT: time-units TYPE: time_t LOC: Config.Timeout.forward DEFAULT: 4 minutes DOC_START This parameter specifies how long Squid should at most attempt in finding a forwarding path for the request before giving up. DOC_END NAME: connect_timeout COMMENT: time-units TYPE: time_t LOC: Config.Timeout.connect DEFAULT: 1 minute DOC_START This parameter specifies how long to wait for the TCP connect to the requested server or peer to complete before Squid should attempt to find another path where to forward the request. DOC_END NAME: peer_connect_timeout COMMENT: time-units TYPE: time_t LOC: Config.Timeout.peer_connect DEFAULT: 30 seconds DOC_START This parameter specifies how long to wait for a pending TCP connection to a peer cache. The default is 30 seconds. You may also set different timeout values for individual neighbors with the 'connect-timeout' option on a 'cache_peer' line. DOC_END NAME: read_timeout COMMENT: time-units TYPE: time_t LOC: Config.Timeout.read DEFAULT: 15 minutes DOC_START Applied on peer server connections. After each successful read(), the timeout will be extended by this amount. If no data is read again after this amount of time, the request is aborted and logged with ERR_READ_TIMEOUT. The default is 15 minutes. DOC_END NAME: write_timeout COMMENT: time-units TYPE: time_t LOC: Config.Timeout.write DEFAULT: 15 minutes DOC_START This timeout is tracked for all connections that have data available for writing and are waiting for the socket to become ready. After each successful write, the timeout is extended by the configured amount. If Squid has data to write but the connection is not ready for the configured duration, the transaction associated with the connection is terminated. The default is 15 minutes. DOC_END NAME: request_timeout TYPE: time_t LOC: Config.Timeout.request DEFAULT: 5 minutes DOC_START How long to wait for complete HTTP request headers after initial connection establishment. DOC_END NAME: client_idle_pconn_timeout persistent_request_timeout TYPE: time_t LOC: Config.Timeout.clientIdlePconn DEFAULT: 2 minutes DOC_START How long to wait for the next HTTP request on a persistent client connection after the previous request completes. DOC_END NAME: ftp_client_idle_timeout TYPE: time_t LOC: Config.Timeout.ftpClientIdle DEFAULT: 30 minutes DOC_START How long to wait for an FTP request on a connection to Squid ftp_port. Many FTP clients do not deal with idle connection closures well, necessitating a longer default timeout than client_idle_pconn_timeout used for incoming HTTP requests. DOC_END NAME: client_lifetime COMMENT: time-units TYPE: time_t LOC: Config.Timeout.lifetime DEFAULT: 1 day DOC_START The maximum amount of time a client (browser) is allowed to remain connected to the cache process. This protects the Cache from having a lot of sockets (and hence file descriptors) tied up in a CLOSE_WAIT state from remote clients that go away without properly shutting down (either because of a network failure or because of a poor client implementation). The default is one day, 1440 minutes. NOTE: The default value is intended to be much larger than any client would ever need to be connected to your cache. You should probably change client_lifetime only as a last resort. If you seem to have many client connections tying up filedescriptors, we recommend first tuning the read_timeout, request_timeout, persistent_request_timeout and quick_abort values. DOC_END NAME: half_closed_clients TYPE: onoff LOC: Config.onoff.half_closed_clients DEFAULT: off DOC_START Some clients may shutdown the sending side of their TCP connections, while leaving their receiving sides open. Sometimes, Squid can not tell the difference between a half-closed and a fully-closed TCP connection. By default, Squid will immediately close client connections when read(2) returns "no more data to read." Change this option to 'on' and Squid will keep open connections until a read(2) or write(2) on the socket returns an error. This may show some benefits for reverse proxies. But if not it is recommended to leave OFF. DOC_END NAME: server_idle_pconn_timeout pconn_timeout TYPE: time_t LOC: Config.Timeout.serverIdlePconn DEFAULT: 1 minute DOC_START Timeout for idle persistent connections to servers and other proxies. DOC_END NAME: ident_timeout TYPE: time_t IFDEF: USE_IDENT LOC: Ident::TheConfig.timeout DEFAULT: 10 seconds DOC_START Maximum time to wait for IDENT lookups to complete. If this is too high, and you enabled IDENT lookups from untrusted users, you might be susceptible to denial-of-service by having many ident requests going at once. DOC_END NAME: shutdown_lifetime COMMENT: time-units TYPE: time_t LOC: Config.shutdownLifetime DEFAULT: 30 seconds DOC_START When SIGTERM or SIGHUP is received, the cache is put into "shutdown pending" mode until all active sockets are closed. This value is the lifetime to set for all open descriptors during shutdown mode. Any active clients after this many seconds will receive a 'timeout' message. DOC_END COMMENT_START ADMINISTRATIVE PARAMETERS ----------------------------------------------------------------------------- COMMENT_END NAME: cache_mgr TYPE: string DEFAULT: webmaster LOC: Config.adminEmail DOC_START Email-address of local cache manager who will receive mail if the cache dies. The default is "webmaster". DOC_END NAME: mail_from TYPE: string DEFAULT: none LOC: Config.EmailFrom DOC_START From: email-address for mail sent when the cache dies. The default is to use 'squid@unique_hostname'. See also: unique_hostname directive. DOC_END NAME: mail_program TYPE: eol DEFAULT: mail LOC: Config.EmailProgram DOC_START Email program used to send mail if the cache dies. The default is "mail". The specified program must comply with the standard Unix mail syntax: mail-program recipient < mailfile Optional command line options can be specified. DOC_END NAME: cache_effective_user TYPE: string DEFAULT: @DEFAULT_CACHE_EFFECTIVE_USER@ LOC: Config.effectiveUser DOC_START If you start Squid as root, it will change its effective/real UID/GID to the user specified below. The default is to change to UID of @DEFAULT_CACHE_EFFECTIVE_USER@. see also; cache_effective_group DOC_END NAME: cache_effective_group TYPE: string DEFAULT: none DEFAULT_DOC: Use system group memberships of the cache_effective_user account LOC: Config.effectiveGroup DOC_START Squid sets the GID to the effective user's default group ID (taken from the password file) and supplementary group list from the groups membership. If you want Squid to run with a specific GID regardless of the group memberships of the effective user then set this to the group (or GID) you want Squid to run as. When set all other group privileges of the effective user are ignored and only this GID is effective. If Squid is not started as root the user starting Squid MUST be member of the specified group. This option is not recommended by the Squid Team. Our preference is for administrators to configure a secure user account for squid with UID/GID matching system policies. DOC_END NAME: httpd_suppress_version_string COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.httpd_suppress_version_string DOC_START Suppress Squid version string info in HTTP headers and HTML error pages. DOC_END NAME: visible_hostname TYPE: string LOC: Config.visibleHostname DEFAULT: none DEFAULT_DOC: Automatically detect the system host name DOC_START If you want to present a special hostname in error messages, etc, define this. Otherwise, the return value of gethostname() will be used. If you have multiple caches in a cluster and get errors about IP-forwarding you must set them to have individual names with this setting. DOC_END NAME: unique_hostname TYPE: string LOC: Config.uniqueHostname DEFAULT: none DEFAULT_DOC: Copy the value from visible_hostname DOC_START If you want to have multiple machines with the same 'visible_hostname' you must give each machine a different 'unique_hostname' so forwarding loops can be detected. DOC_END NAME: hostname_aliases TYPE: wordlist LOC: Config.hostnameAliases DEFAULT: none DOC_START A list of other DNS names your cache has. DOC_END NAME: umask TYPE: int LOC: Config.umask DEFAULT: 027 DOC_START Minimum umask which should be enforced while the proxy is running, in addition to the umask set at startup. For a traditional octal representation of umasks, start your value with 0. DOC_END COMMENT_START OPTIONS FOR THE CACHE REGISTRATION SERVICE ----------------------------------------------------------------------------- This section contains parameters for the (optional) cache announcement service. This service is provided to help cache administrators locate one another in order to join or create cache hierarchies. An 'announcement' message is sent (via UDP) to the registration service by Squid. By default, the announcement message is NOT SENT unless you enable it with 'announce_period' below. The announcement message includes your hostname, plus the following information from this configuration file: http_port icp_port cache_mgr All current information is processed regularly and made available on the Web at http://www.ircache.net/Cache/Tracker/. COMMENT_END NAME: announce_period TYPE: time_t LOC: Config.Announce.period DEFAULT: 0 DEFAULT_DOC: Announcement messages disabled. DOC_START This is how frequently to send cache announcements. To enable announcing your cache, just set an announce period. Example: announce_period 1 day DOC_END NAME: announce_host TYPE: string DEFAULT: tracker.ircache.net LOC: Config.Announce.host DOC_START Set the hostname where announce registration messages will be sent. See also announce_port and announce_file DOC_END NAME: announce_file TYPE: string DEFAULT: none LOC: Config.Announce.file DOC_START The contents of this file will be included in the announce registration messages. DOC_END NAME: announce_port TYPE: u_short DEFAULT: 3131 LOC: Config.Announce.port DOC_START Set the port where announce registration messages will be sent. See also announce_host and announce_file DOC_END COMMENT_START HTTPD-ACCELERATOR OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: httpd_accel_surrogate_id TYPE: string DEFAULT: none DEFAULT_DOC: visible_hostname is used if no specific ID is set. LOC: Config.Accel.surrogate_id DOC_START Surrogates (http://www.esi.org/architecture_spec_1.0.html) need an identification token to allow control targeting. Because a farm of surrogates may all perform the same tasks, they may share an identification token. DOC_END NAME: http_accel_surrogate_remote COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.surrogate_is_remote DOC_START Remote surrogates (such as those in a CDN) honour the header "Surrogate-Control: no-store-remote". Set this to on to have squid behave as a remote surrogate. DOC_END NAME: esi_parser IFDEF: USE_SQUID_ESI COMMENT: libxml2|expat|custom TYPE: string LOC: ESIParser::Type DEFAULT: custom DOC_START ESI markup is not strictly XML compatible. The custom ESI parser will give higher performance, but cannot handle non ASCII character encodings. DOC_END COMMENT_START DELAY POOL PARAMETERS ----------------------------------------------------------------------------- COMMENT_END NAME: delay_pools TYPE: delay_pool_count DEFAULT: 0 IFDEF: USE_DELAY_POOLS LOC: Config.Delay DOC_START This represents the number of delay pools to be used. For example, if you have one class 2 delay pool and one class 3 delays pool, you have a total of 2 delay pools. See also delay_parameters, delay_class, delay_access for pool configuration details. DOC_END NAME: delay_class TYPE: delay_pool_class DEFAULT: none IFDEF: USE_DELAY_POOLS LOC: Config.Delay DOC_START This defines the class of each delay pool. There must be exactly one delay_class line for each delay pool. For example, to define two delay pools, one of class 2 and one of class 3, the settings above and here would be: Example: delay_pools 4 # 4 delay pools delay_class 1 2 # pool 1 is a class 2 pool delay_class 2 3 # pool 2 is a class 3 pool delay_class 3 4 # pool 3 is a class 4 pool delay_class 4 5 # pool 4 is a class 5 pool The delay pool classes are: class 1 Everything is limited by a single aggregate bucket. class 2 Everything is limited by a single aggregate bucket as well as an "individual" bucket chosen from bits 25 through 32 of the IPv4 address. class 3 Everything is limited by a single aggregate bucket as well as a "network" bucket chosen from bits 17 through 24 of the IP address and a "individual" bucket chosen from bits 17 through 32 of the IPv4 address. class 4 Everything in a class 3 delay pool, with an additional limit on a per user basis. This only takes effect if the username is established in advance - by forcing authentication in your http_access rules. class 5 Requests are grouped according their tag (see external_acl's tag= reply). Each pool also requires a delay_parameters directive to configure the pool size and speed limits used whenever the pool is applied to a request. Along with a set of delay_access directives to determine when it is used. NOTE: If an IP address is a.b.c.d -> bits 25 through 32 are "d" -> bits 17 through 24 are "c" -> bits 17 through 32 are "c * 256 + d" NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic. This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. See also delay_parameters and delay_access. DOC_END NAME: delay_access TYPE: delay_pool_access DEFAULT: none DEFAULT_DOC: Deny using the pool, unless allow rules exist in squid.conf for the pool. IFDEF: USE_DELAY_POOLS LOC: Config.Delay DOC_START This is used to determine which delay pool a request falls into. delay_access is sorted per pool and the matching starts with pool 1, then pool 2, ..., and finally pool N. The first delay pool where the request is allowed is selected for the request. If it does not allow the request to any pool then the request is not delayed (default). For example, if you want some_big_clients in delay pool 1 and lotsa_little_clients in delay pool 2: delay_access 1 allow some_big_clients delay_access 1 deny all delay_access 2 allow lotsa_little_clients delay_access 2 deny all delay_access 3 allow authenticated_clients See also delay_parameters and delay_class. DOC_END NAME: delay_parameters TYPE: delay_pool_rates DEFAULT: none IFDEF: USE_DELAY_POOLS LOC: Config.Delay DOC_START This defines the parameters for a delay pool. Each delay pool has a number of "buckets" associated with it, as explained in the description of delay_class. For a class 1 delay pool, the syntax is: delay_class pool 1 delay_parameters pool aggregate For a class 2 delay pool: delay_class pool 2 delay_parameters pool aggregate individual For a class 3 delay pool: delay_class pool 3 delay_parameters pool aggregate network individual For a class 4 delay pool: delay_class pool 4 delay_parameters pool aggregate network individual user For a class 5 delay pool: delay_class pool 5 delay_parameters pool tagrate The option variables are: pool a pool number - ie, a number between 1 and the number specified in delay_pools as used in delay_class lines. aggregate the speed limit parameters for the aggregate bucket (class 1, 2, 3). individual the speed limit parameters for the individual buckets (class 2, 3). network the speed limit parameters for the network buckets (class 3). user the speed limit parameters for the user buckets (class 4). tagrate the speed limit parameters for the tag buckets (class 5). A pair of delay parameters is written restore/maximum, where restore is the number of bytes (not bits - modem and network speeds are usually quoted in bits) per second placed into the bucket, and maximum is the maximum number of bytes which can be in the bucket at any time. There must be one delay_parameters line for each delay pool. For example, if delay pool number 1 is a class 2 delay pool as in the above example, and is being used to strictly limit each host to 64Kbit/sec (plus overheads), with no overall limit, the line is: delay_parameters 1 none 8000/8000 Note that 8 x 8K Byte/sec -> 64K bit/sec. Note that the word 'none' is used to represent no limit. And, if delay pool number 2 is a class 3 delay pool as in the above example, and you want to limit it to a total of 256Kbit/sec (strict limit) with each 8-bit network permitted 64Kbit/sec (strict limit) and each individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits to permit a decent web page to be downloaded at a decent speed (if the network is not being limited due to overuse) but slow down large downloads more significantly: delay_parameters 2 32000/32000 8000/8000 600/8000 Note that 8 x 32K Byte/sec -> 256K bit/sec. 8 x 8K Byte/sec -> 64K bit/sec. 8 x 600 Byte/sec -> 4800 bit/sec. Finally, for a class 4 delay pool as in the example - each user will be limited to 128Kbits/sec no matter how many workstations they are logged into.: delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000 See also delay_class and delay_access. DOC_END NAME: delay_initial_bucket_level COMMENT: (percent, 0-100) TYPE: u_short DEFAULT: 50 IFDEF: USE_DELAY_POOLS LOC: Config.Delay.initial DOC_START The initial bucket percentage is used to determine how much is put in each bucket when squid starts, is reconfigured, or first notices a host accessing it (in class 2 and class 3, individual hosts and networks only have buckets associated with them once they have been "seen" by squid). DOC_END COMMENT_START CLIENT DELAY POOL PARAMETERS ----------------------------------------------------------------------------- COMMENT_END NAME: client_delay_pools TYPE: client_delay_pool_count DEFAULT: 0 IFDEF: USE_DELAY_POOLS LOC: Config.ClientDelay DOC_START This option specifies the number of client delay pools used. It must preceed other client_delay_* options. Example: client_delay_pools 2 See also client_delay_parameters and client_delay_access. DOC_END NAME: client_delay_initial_bucket_level COMMENT: (percent, 0-no_limit) TYPE: u_short DEFAULT: 50 IFDEF: USE_DELAY_POOLS LOC: Config.ClientDelay.initial DOC_START This option determines the initial bucket size as a percentage of max_bucket_size from client_delay_parameters. Buckets are created at the time of the "first" connection from the matching IP. Idle buckets are periodically deleted up. You can specify more than 100 percent but note that such "oversized" buckets are not refilled until their size goes down to max_bucket_size from client_delay_parameters. Example: client_delay_initial_bucket_level 50 DOC_END NAME: client_delay_parameters TYPE: client_delay_pool_rates DEFAULT: none IFDEF: USE_DELAY_POOLS LOC: Config.ClientDelay DOC_START This option configures client-side bandwidth limits using the following format: client_delay_parameters pool speed_limit max_bucket_size pool is an integer ID used for client_delay_access matching. speed_limit is bytes added to the bucket per second. max_bucket_size is the maximum size of a bucket, enforced after any speed_limit additions. Please see the delay_parameters option for more information and examples. Example: client_delay_parameters 1 1024 2048 client_delay_parameters 2 51200 16384 See also client_delay_access. DOC_END NAME: client_delay_access TYPE: client_delay_pool_access DEFAULT: none DEFAULT_DOC: Deny use of the pool, unless allow rules exist in squid.conf for the pool. IFDEF: USE_DELAY_POOLS LOC: Config.ClientDelay DOC_START This option determines the client-side delay pool for the request: client_delay_access pool_ID allow|deny acl_name All client_delay_access options are checked in their pool ID order, starting with pool 1. The first checked pool with allowed request is selected for the request. If no ACL matches or there are no client_delay_access options, the request bandwidth is not limited. The ACL-selected pool is then used to find the client_delay_parameters for the request. Client-side pools are not used to aggregate clients. Clients are always aggregated based on their source IP addresses (one bucket per source IP). This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. Additionally, only the client TCP connection details are available. ACLs testing HTTP properties will not work. Please see delay_access for more examples. Example: client_delay_access 1 allow low_rate_network client_delay_access 2 allow vips_network See also client_delay_parameters and client_delay_pools. DOC_END COMMENT_START WCCPv1 AND WCCPv2 CONFIGURATION OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: wccp_router TYPE: address LOC: Config.Wccp.router DEFAULT: any_addr DEFAULT_DOC: WCCP disabled. IFDEF: USE_WCCP DOC_START Use this option to define your WCCP ``home'' router for Squid. wccp_router supports a single WCCP(v1) router wccp2_router supports multiple WCCPv2 routers only one of the two may be used at the same time and defines which version of WCCP to use. DOC_END NAME: wccp2_router TYPE: IpAddress_list LOC: Config.Wccp2.router DEFAULT: none DEFAULT_DOC: WCCPv2 disabled. IFDEF: USE_WCCPv2 DOC_START Use this option to define your WCCP ``home'' router for Squid. wccp_router supports a single WCCP(v1) router wccp2_router supports multiple WCCPv2 routers only one of the two may be used at the same time and defines which version of WCCP to use. DOC_END NAME: wccp_version TYPE: int LOC: Config.Wccp.version DEFAULT: 4 IFDEF: USE_WCCP DOC_START This directive is only relevant if you need to set up WCCP(v1) to some very old and end-of-life Cisco routers. In all other setups it must be left unset or at the default setting. It defines an internal version in the WCCP(v1) protocol, with version 4 being the officially documented protocol. According to some users, Cisco IOS 11.2 and earlier only support WCCP version 3. If you're using that or an earlier version of IOS, you may need to change this value to 3, otherwise do not specify this parameter. DOC_END NAME: wccp2_rebuild_wait TYPE: onoff LOC: Config.Wccp2.rebuildwait DEFAULT: on IFDEF: USE_WCCPv2 DOC_START If this is enabled Squid will wait for the cache dir rebuild to finish before sending the first wccp2 HereIAm packet DOC_END NAME: wccp2_forwarding_method TYPE: wccp2_method LOC: Config.Wccp2.forwarding_method DEFAULT: gre IFDEF: USE_WCCPv2 DOC_START WCCP2 allows the setting of forwarding methods between the router/switch and the cache. Valid values are as follows: gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel) l2 - L2 redirect (forward the packet using Layer 2/MAC rewriting) Currently (as of IOS 12.4) cisco routers only support GRE. Cisco switches only support the L2 redirect assignment method. DOC_END NAME: wccp2_return_method TYPE: wccp2_method LOC: Config.Wccp2.return_method DEFAULT: gre IFDEF: USE_WCCPv2 DOC_START WCCP2 allows the setting of return methods between the router/switch and the cache for packets that the cache decides not to handle. Valid values are as follows: gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel) l2 - L2 redirect (forward the packet using Layer 2/MAC rewriting) Currently (as of IOS 12.4) cisco routers only support GRE. Cisco switches only support the L2 redirect assignment. If the "ip wccp redirect exclude in" command has been enabled on the cache interface, then it is still safe for the proxy server to use a l2 redirect method even if this option is set to GRE. DOC_END NAME: wccp2_assignment_method TYPE: wccp2_amethod LOC: Config.Wccp2.assignment_method DEFAULT: hash IFDEF: USE_WCCPv2 DOC_START WCCP2 allows the setting of methods to assign the WCCP hash Valid values are as follows: hash - Hash assignment mask - Mask assignment As a general rule, cisco routers support the hash assignment method and cisco switches support the mask assignment method. DOC_END NAME: wccp2_service TYPE: wccp2_service LOC: Config.Wccp2.info DEFAULT_IF_NONE: standard 0 DEFAULT_DOC: Use the 'web-cache' standard service. IFDEF: USE_WCCPv2 DOC_START WCCP2 allows for multiple traffic services. There are two types: "standard" and "dynamic". The standard type defines one service id - http (id 0). The dynamic service ids can be from 51 to 255 inclusive. In order to use a dynamic service id one must define the type of traffic to be redirected; this is done using the wccp2_service_info option. The "standard" type does not require a wccp2_service_info option, just specifying the service id will suffice. MD5 service authentication can be enabled by adding "password=" to the end of this service declaration. Examples: wccp2_service standard 0 # for the 'web-cache' standard service wccp2_service dynamic 80 # a dynamic service type which will be # fleshed out with subsequent options. wccp2_service standard 0 password=foo DOC_END NAME: wccp2_service_info TYPE: wccp2_service_info LOC: Config.Wccp2.info DEFAULT: none IFDEF: USE_WCCPv2 DOC_START Dynamic WCCPv2 services require further information to define the traffic you wish to have diverted. The format is: wccp2_service_info protocol= flags=,.. priority= ports=,.. The relevant WCCPv2 flags: + src_ip_hash, dst_ip_hash + source_port_hash, dst_port_hash + src_ip_alt_hash, dst_ip_alt_hash + src_port_alt_hash, dst_port_alt_hash + ports_source The port list can be one to eight entries. Example: wccp2_service_info 80 protocol=tcp flags=src_ip_hash,ports_source priority=240 ports=80 Note: the service id must have been defined by a previous 'wccp2_service dynamic ' entry. DOC_END NAME: wccp2_weight TYPE: int LOC: Config.Wccp2.weight DEFAULT: 10000 IFDEF: USE_WCCPv2 DOC_START Each cache server gets assigned a set of the destination hash proportional to their weight.

Squid uses persistent connections (when allowed). You can use this option to disable persistent connections with clients. DOC_END NAME: server_persistent_connections TYPE: onoff LOC: Config.onoff.server_pconns DEFAULT: on DOC_START Persistent connection support for servers. Squid uses persistent connections (when allowed). You can use this option to disable persistent connections with servers. DOC_END NAME: persistent_connection_after_error TYPE: onoff LOC: Config.onoff.error_pconns DEFAULT: on DOC_START With this directive the use of persistent connections after HTTP errors can be disabled. Useful if you have clients who fail to handle errors on persistent connections proper. DOC_END NAME: detect_broken_pconn TYPE: onoff LOC: Config.onoff.detect_broken_server_pconns DEFAULT: off DOC_START Some servers have been found to incorrectly signal the use of HTTP/1.0 persistent connections even on replies not compatible, causing significant delays. This server problem has mostly been seen on redirects. By enabling this directive Squid attempts to detect such broken replies and automatically assume the reply is finished after 10 seconds timeout. DOC_END COMMENT_START CACHE DIGEST OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: digest_generation IFDEF: USE_CACHE_DIGESTS TYPE: onoff LOC: Config.onoff.digest_generation DEFAULT: on DOC_START This controls whether the server will generate a Cache Digest of its contents. By default, Cache Digest generation is enabled if Squid is compiled with --enable-cache-digests defined. DOC_END NAME: digest_bits_per_entry IFDEF: USE_CACHE_DIGESTS TYPE: int LOC: Config.digest.bits_per_entry DEFAULT: 5 DOC_START This is the number of bits of the server's Cache Digest which will be associated with the Digest entry for a given HTTP Method and URL (public key) combination. The default is 5.

By default it is set to 10% of the Cache Digest. DOC_END COMMENT_START SNMP OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: snmp_port TYPE: u_short LOC: Config.Port.snmp DEFAULT: 0 DEFAULT_DOC: SNMP disabled. IFDEF: SQUID_SNMP DOC_START The port number where Squid listens for SNMP requests. To enable SNMP support set this to a suitable port number. Port number 3401 is often used for the Squid SNMP agent. By default it's set to "0" (disabled) Example: snmp_port 3401 DOC_END NAME: snmp_access TYPE: acl_access LOC: Config.accessList.snmp DEFAULT: none DEFAULT_DOC: Deny, unless rules exist in squid.conf. IFDEF: SQUID_SNMP DOC_START Allowing or denying access to the SNMP port. All access to the agent is denied by default. usage: snmp_access allow|deny [!]aclname ... This clause only supports fast acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. Example: snmp_access allow snmppublic localhost snmp_access deny all DOC_END NAME: snmp_incoming_address TYPE: address LOC: Config.Addrs.snmp_incoming DEFAULT: any_addr DEFAULT_DOC: Accept SNMP packets from all machine interfaces. IFDEF: SQUID_SNMP DOC_START Just like 'udp_incoming_address', but for the SNMP port. snmp_incoming_address is used for the SNMP socket receiving messages from SNMP agents. The default snmp_incoming_address is to listen on all available network interfaces. DOC_END NAME: snmp_outgoing_address TYPE: address LOC: Config.Addrs.snmp_outgoing DEFAULT: no_addr DEFAULT_DOC: Use snmp_incoming_address or an address selected by the operating system. IFDEF: SQUID_SNMP DOC_START Just like 'udp_outgoing_address', but for the SNMP port. snmp_outgoing_address is used for SNMP packets returned to SNMP agents. If snmp_outgoing_address is not set it will use the same socket as snmp_incoming_address. Only change this if you want to have SNMP replies sent using another address than where this Squid listens for SNMP queries. NOTE, snmp_incoming_address and snmp_outgoing_address can not have the same value since they both use the same port. DOC_END COMMENT_START ICP OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: icp_port udp_port TYPE: u_short DEFAULT: 0 DEFAULT_DOC: ICP disabled. LOC: Config.Port.icp DOC_START The port number where Squid sends and receives ICP queries to and from neighbor caches. The standard UDP port for ICP is 3130. Example: icp_port @DEFAULT_ICP_PORT@ DOC_END NAME: htcp_port IFDEF: USE_HTCP TYPE: u_short DEFAULT: 0 DEFAULT_DOC: HTCP disabled. LOC: Config.Port.htcp DOC_START The port number where Squid sends and receives HTCP queries to and from neighbor caches. To turn it on you want to set it to 4827. Example: htcp_port 4827 DOC_END NAME: log_icp_queries COMMENT: on|off TYPE: onoff DEFAULT: on LOC: Config.onoff.log_udp DOC_START If set, ICP queries are logged to access.log. You may wish do disable this if your ICP load is VERY high to speed things up or to simplify log analysis. DOC_END NAME: udp_incoming_address TYPE: address LOC:Config.Addrs.udp_incoming DEFAULT: any_addr DEFAULT_DOC: Accept packets from all machine interfaces. DOC_START udp_incoming_address is used for UDP packets received from other caches. The default behavior is to not bind to any specific address. Only change this if you want to have all UDP queries received on a specific interface/address. NOTE: udp_incoming_address is used by the ICP, HTCP, and DNS modules. Altering it will affect all of them in the same manner. see also; udp_outgoing_address NOTE, udp_incoming_address and udp_outgoing_address can not have the same value since they both use the same port. DOC_END NAME: udp_outgoing_address TYPE: address LOC: Config.Addrs.udp_outgoing DEFAULT: no_addr DEFAULT_DOC: Use udp_incoming_address or an address selected by the operating system. DOC_START udp_outgoing_address is used for UDP packets sent out to other caches. The default behavior is to not bind to any specific address. Instead it will use the same socket as udp_incoming_address. Only change this if you want to have UDP queries sent using another address than where this Squid listens for UDP queries from other caches. NOTE: udp_outgoing_address is used by the ICP, HTCP, and DNS modules. Altering it will affect all of them in the same manner. see also; udp_incoming_address NOTE, udp_incoming_address and udp_outgoing_address can not have the same value since they both use the same port. DOC_END NAME: icp_hit_stale COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.icp_hit_stale DOC_START If you want to return ICP_HIT for stale cache objects, set this option to 'on'. If you have sibling relationships with caches in other administrative domains, this should be 'off'. If you only have sibling relationships with caches under your control, it is probably okay to set this to 'on'. If set to 'on', your siblings should use the option "allow-miss" on their cache_peer lines for connecting to you. DOC_END NAME: minimum_direct_hops TYPE: int DEFAULT: 4 LOC: Config.minDirectHops DOC_START If using the ICMP pinging stuff, do direct fetches for sites which are no more than this many hops away. DOC_END NAME: minimum_direct_rtt COMMENT: (msec) TYPE: int DEFAULT: 400 LOC: Config.minDirectRtt DOC_START If using the ICMP pinging stuff, do direct fetches for sites which are no more than this many rtt milliseconds away. DOC_END NAME: netdb_low TYPE: int DEFAULT: 900 LOC: Config.Netdb.low DOC_START The low water mark for the ICMP measurement database. Note: high watermark controlled by netdb_high directive. These watermarks are counts, not percents. The defaults are (low) 900 and (high) 1000. When the high water mark is reached, database entries will be deleted until the low mark is reached. DOC_END NAME: netdb_high TYPE: int DEFAULT: 1000 LOC: Config.Netdb.high DOC_START The high water mark for the ICMP measurement database. Note: low watermark controlled by netdb_low directive. These watermarks are counts, not percents. The defaults are (low) 900 and (high) 1000. When the high water mark is reached, database entries will be deleted until the low mark is reached. DOC_END NAME: netdb_ping_period TYPE: time_t LOC: Config.Netdb.period DEFAULT: 5 minutes DOC_START The minimum period for measuring a site. There will be at least this much delay between successive pings to the same network. The default is five minutes. DOC_END NAME: query_icmp COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.query_icmp DOC_START If you want to ask your peers to include ICMP data in their ICP replies, enable this option. If your peer has configured Squid (during compilation) with '--enable-icmp' that peer will send ICMP pings to origin server sites of the URLs it receives. If you enable this option the ICP replies from that peer will include the ICMP data (if available). Then, when choosing a parent cache, Squid will choose the parent with the minimal RTT to the origin server. When this happens, the hierarchy field of the access.log will be "CLOSEST_PARENT_MISS". This option is off by default. DOC_END NAME: test_reachability COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.test_reachability DOC_START When this is 'on', ICP MISS replies will be ICP_MISS_NOFETCH instead of ICP_MISS if the target host is NOT in the ICMP database, or has a zero RTT. DOC_END NAME: icp_query_timeout COMMENT: (msec) DEFAULT: 0 DEFAULT_DOC: Dynamic detection. TYPE: int LOC: Config.Timeout.icp_query DOC_START Normally Squid will automatically determine an optimal ICP query timeout value based on the round-trip-time of recent ICP queries. If you want to override the value determined by Squid, set this 'icp_query_timeout' to a non-zero value. This value is specified in MILLISECONDS, so, to use a 2-second timeout (the old default), you would write: icp_query_timeout 2000 DOC_END NAME: maximum_icp_query_timeout COMMENT: (msec) DEFAULT: 2000 TYPE: int LOC: Config.Timeout.icp_query_max DOC_START Normally the ICP query timeout is determined dynamically. But sometimes it can lead to very large values (say 5 seconds). Use this option to put an upper limit on the dynamic timeout value. Do NOT use this option to always use a fixed (instead of a dynamic) timeout value. To set a fixed timeout see the 'icp_query_timeout' directive. DOC_END NAME: minimum_icp_query_timeout COMMENT: (msec) DEFAULT: 5 TYPE: int LOC: Config.Timeout.icp_query_min DOC_START Normally the ICP query timeout is determined dynamically. But sometimes it can lead to very small timeouts, even lower than the normal latency variance on your link due to traffic. Use this option to put an lower limit on the dynamic timeout value. Do NOT use this option to always use a fixed (instead of a dynamic) timeout value. To set a fixed timeout see the 'icp_query_timeout' directive. DOC_END NAME: background_ping_rate COMMENT: time-units TYPE: time_t DEFAULT: 10 seconds LOC: Config.backgroundPingRate DOC_START Controls how often the ICP pings are sent to siblings that have background-ping set. DOC_END COMMENT_START MULTICAST ICP OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: mcast_groups TYPE: wordlist LOC: Config.mcast_group_list DEFAULT: none DOC_START This tag specifies a list of multicast groups which your server should join to receive multicasted ICP queries. NOTE! Be very careful what you put here! Be sure you understand the difference between an ICP _query_ and an ICP _reply_. This option is to be set only if you want to RECEIVE multicast queries. Do NOT set this option to SEND multicast ICP (use cache_peer for that). ICP replies are always sent via unicast, so this option does not affect whether or not you will receive replies from multicast group members. You must be very careful to NOT use a multicast address which is already in use by another group of caches. If you are unsure about multicast, please read the Multicast chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/). Usage: mcast_groups 239.128.16.128 224.0.1.20 By default, Squid doesn't listen on any multicast groups. DOC_END NAME: mcast_miss_addr IFDEF: MULTICAST_MISS_STREAM TYPE: address LOC: Config.mcast_miss.addr DEFAULT: no_addr DEFAULT_DOC: disabled. DOC_START If you enable this option, every "cache miss" URL will be sent out on the specified multicast address. Do not enable this option unless you are are absolutely certain you understand what you are doing. DOC_END NAME: mcast_miss_ttl IFDEF: MULTICAST_MISS_STREAM TYPE: u_short LOC: Config.mcast_miss.ttl DEFAULT: 16 DOC_START This is the time-to-live value for packets multicasted when multicasting off cache miss URLs is enabled. By default this is set to 'site scope', i.e. 16. DOC_END NAME: mcast_miss_port IFDEF: MULTICAST_MISS_STREAM TYPE: u_short LOC: Config.mcast_miss.port DEFAULT: 3135 DOC_START This is the port number to be used in conjunction with 'mcast_miss_addr'. DOC_END NAME: mcast_miss_encode_key IFDEF: MULTICAST_MISS_STREAM TYPE: string LOC: Config.mcast_miss.encode_key DEFAULT: XXXXXXXXXXXXXXXX DOC_START The URLs that are sent in the multicast miss stream are encrypted. This is the encryption key. DOC_END NAME: mcast_icp_query_timeout COMMENT: (msec) DEFAULT: 2000 TYPE: int LOC: Config.Timeout.mcast_icp_query DOC_START For multicast peers, Squid regularly sends out ICP "probes" to count how many other peers are listening on the given multicast address. This value specifies how long Squid should wait to count all the replies. The default is 2000 msec, or 2 seconds. DOC_END COMMENT_START INTERNAL ICON OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: icon_directory TYPE: string LOC: Config.icons.directory DEFAULT: @DEFAULT_ICON_DIR@ DOC_START Where the icons are stored. These are normally kept in @DEFAULT_ICON_DIR@ DOC_END NAME: global_internal_static TYPE: onoff LOC: Config.onoff.global_internal_static DEFAULT: on DOC_START This directive controls is Squid should intercept all requests for /squid-internal-static/ no matter which host the URL is requesting (default on setting), or if nothing special should be done for such URLs (off setting). The purpose of this directive is to make icons etc work better in complex cache hierarchies where it may not always be possible for all corners in the cache mesh to reach the server generating a directory listing. DOC_END NAME: short_icon_urls TYPE: onoff LOC: Config.icons.use_short_names DEFAULT: on DOC_START If this is enabled Squid will use short URLs for icons. If disabled it will revert to the old behavior of including it's own name and port in the URL. If you run a complex cache hierarchy with a mix of Squid and other proxies you may need to disable this directive. DOC_END COMMENT_START ERROR PAGE OPTIONS ----------------------------------------------------------------------------- COMMENT_END NAME: error_directory TYPE: string LOC: Config.errorDirectory DEFAULT: none DEFAULT_DOC: Send error pages in the clients preferred language DOC_START If you wish to create your own versions of the default error files to customize them to suit your company copy the error/template files to another directory and point this tag at them. WARNING: This option will disable multi-language support on error pages if used. The squid developers are interested in making squid available in a wide variety of languages. If you are making translations for a language that Squid does not currently provide please consider contributing your translation back to the project. http://wiki.squid-cache.org/Translations The squid developers working on translations are happy to supply drop-in translated error files in exchange for any new language contributions. DOC_END NAME: error_default_language IFDEF: USE_ERR_LOCALES TYPE: string LOC: Config.errorDefaultLanguage DEFAULT: none DEFAULT_DOC: Generate English language pages. DOC_START Set the default language which squid will send error pages in if no existing translation matches the clients language preferences. If unset (default) generic English will be used. The squid developers are interested in making squid available in a wide variety of languages. If you are interested in making translations for any language see the squid wiki for details. http://wiki.squid-cache.org/Translations DOC_END NAME: error_log_languages IFDEF: USE_ERR_LOCALES TYPE: onoff LOC: Config.errorLogMissingLanguages DEFAULT: on DOC_START Log to cache.log what languages users are attempting to auto-negotiate for translations. Successful negotiations are not logged. Only failures have meaning to indicate that Squid may need an upgrade of its error page translations. DOC_END NAME: err_page_stylesheet TYPE: string LOC: Config.errorStylesheet DEFAULT: @DEFAULT_CONFIG_DIR@/errorpage.css DOC_START CSS Stylesheet to pattern the display of Squid default error pages. For information on CSS see http://www.w3.org/Style/CSS/ DOC_END NAME: err_html_text TYPE: eol LOC: Config.errHtmlText DEFAULT: none DOC_START HTML text to include in error messages. Make this a "mailto" URL to your admin address, or maybe just a link to your organizations Web page. To include this in your error messages, you must rewrite the error template files (found in the "errors" directory). Wherever you want the 'err_html_text' line to appear, insert a %L tag in the error template file. DOC_END NAME: email_err_data COMMENT: on|off TYPE: onoff LOC: Config.onoff.emailErrData DEFAULT: on DOC_START If enabled, information about the occurred error will be included in the mailto links of the ERR pages (if %W is set) so that the email body contains the data. Syntax is %w DOC_END NAME: deny_info TYPE: denyinfo LOC: Config.denyInfoList DEFAULT: none DOC_START Usage: deny_info err_page_name acl or deny_info http://... acl or deny_info TCP_RESET acl This can be used to return a ERR_ page for requests which do not pass the 'http_access' rules. Squid remembers the last acl it evaluated in http_access, and if a 'deny_info' line exists for that ACL Squid returns a corresponding error page. The acl is typically the last acl on the http_access deny line which denied access. The exceptions to this rule are: - When Squid needs to request authentication credentials. It's then the first authentication related acl encountered - When none of the http_access lines matches. It's then the last acl processed on the last http_access line. - When the decision to deny access was made by an adaptation service, the acl name is the corresponding eCAP or ICAP service_name. NP: If providing your own custom error pages with error_directory you may also specify them by your custom file name: Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys By defaut Squid will send "403 Forbidden". A different 4xx or 5xx may be specified by prefixing the file name with the code and a colon. e.g. 404:ERR_CUSTOM_ACCESS_DENIED Alternatively you can tell Squid to reset the TCP connection by specifying TCP_RESET. Or you can specify an error URL or URL pattern. The browsers will get redirected to the specified URL after formatting tags have been replaced. Redirect will be done with 302 or 307 according to HTTP/1.1 specs. A different 3xx code may be specified by prefixing the URL. e.g. 303:http://example.com/ URL FORMAT TAGS: %a - username (if available. Password NOT included) %B - FTP path URL %e - Error number %E - Error description %h - Squid hostname %H - Request domain name %i - Client IP Address %M - Request Method %o - Message result from external ACL helper %p - Request Port number %P - Request Protocol name %R - Request URL path %T - Timestamp in RFC 1123 format %U - Full canonical URL from client (HTTPS URLs terminate with *) %u - Full canonical URL from client %w - Admin email from squid.conf %x - Error name %% - Literal percent (%) code DOC_END COMMENT_START OPTIONS INFLUENCING REQUEST FORWARDING ----------------------------------------------------------------------------- COMMENT_END NAME: nonhierarchical_direct TYPE: onoff LOC: Config.onoff.nonhierarchical_direct DEFAULT: on DOC_START By default, Squid will send any non-hierarchical requests (not cacheable request type) direct to origin servers. When this is set to "off", Squid will prefer to send these requests to parents. Note that in most configurations, by turning this off you will only add latency to these request without any improvement in global hit ratio. This option only sets a preference. If the parent is unavailable a direct connection to the origin server may still be attempted. To completely prevent direct connections use never_direct. DOC_END NAME: prefer_direct TYPE: onoff LOC: Config.onoff.prefer_direct DEFAULT: off DOC_START Normally Squid tries to use parents for most requests. If you for some reason like it to first try going direct and only use a parent if going direct fails set this to on. By combining nonhierarchical_direct off and prefer_direct on you can set up Squid to use a parent as a backup path if going direct fails. Note: If you want Squid to use parents for all requests see the never_direct directive. prefer_direct only modifies how Squid acts on cacheable requests. DOC_END NAME: cache_miss_revalidate COMMENT: on|off TYPE: onoff DEFAULT: on LOC: Config.onoff.cache_miss_revalidate DOC_START RFC 7232 defines a conditional request mechanism to prevent response objects being unnecessarily transferred over the network. If that mechanism is used by the client and a cache MISS occurs it can prevent new cache entries being created. This option determines whether Squid on cache MISS will pass the client revalidation request to the server or tries to fetch new content for caching. It can be useful while the cache is mostly empty to more quickly have the cache populated by generating non-conditional GETs. When set to 'on' (default), Squid will pass all client If-* headers to the server. This permits server responses without a cacheable payload to be delivered and on MISS no new cache entry is created. When set to 'off' and if the request is cacheable, Squid will remove the clients If-Modified-Since and If-None-Match headers from the request sent to the server. This requests a 200 status response from the server to create a new cache entry with. DOC_END NAME: always_direct TYPE: acl_access LOC: Config.accessList.AlwaysDirect DEFAULT: none DEFAULT_DOC: Prevent any cache_peer being used for this request. DOC_START Usage: always_direct allow|deny [!]aclname ... Here you can use ACL elements to specify requests which should ALWAYS be forwarded by Squid to the origin servers without using any peers. For example, to always directly forward requests for local servers ignoring any parents or siblings you may have use something like: acl local-servers dstdomain my.domain.net always_direct allow local-servers To always forward FTP requests directly, use acl FTP proto FTP always_direct allow FTP NOTE: There is a similar, but opposite option named 'never_direct'. You need to be aware that "always_direct deny foo" is NOT the same thing as "never_direct allow foo". You may need to use a deny rule to exclude a more-specific case of some other rule. Example: acl local-external dstdomain external.foo.net acl local-servers dstdomain .foo.net always_direct deny local-external always_direct allow local-servers NOTE: If your goal is to make the client forward the request directly to the origin server bypassing Squid then this needs to be done in the client configuration. Squid configuration can only tell Squid how Squid should fetch the object. NOTE: This directive is not related to caching. The replies is cached as usual even if you use always_direct. To not cache the replies see the 'cache' directive. This clause supports both fast and slow acl types. See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. DOC_END NAME: never_direct TYPE: acl_access LOC: Config.accessList.NeverDirect DEFAULT: none DEFAULT_DOC: Allow DNS results to be used for this request. DOC_START Usage: never_direct allow|deny [!]aclname ... never_direct is the opposite of always_direct. Please read the description for always_direct if you have not already. With 'never_direct' you can use ACL elements to specify requests which should NEVER be forwarded directly to origin servers. For example, to force the use of a proxy for all requests, except those in your local domain use something like: acl local-servers dstdomain .foo.net never_direct deny local-servers never_direct allow all or if Squid is inside a firewall and there are local intranet servers inside the firewall use something like: acl local-intranet dstdomain .foo.net acl local-external dstdomain external.foo.net always_direct deny local-external always_direct allow local-intranet never_direct allow all This clause supports both fast and slow acl types.

DOC_END NAME: accept_filter TYPE: string DEFAULT: none LOC: Config.accept_filter DOC_START FreeBSD: The name of an accept(2) filter to install on Squid's listen socket(s). This feature is perhaps specific to FreeBSD and requires support in the kernel. The 'httpready' filter delays delivering new connections to Squid until a full HTTP request has been received. See the accf_http(9) man page for details. The 'dataready' filter delays delivering new connections to Squid until there is some data to process. See the accf_dataready(9) man page for details. Linux: The 'data' filter delays delivering of new connections to Squid until there is some data to process by TCP_ACCEPT_DEFER. You may optionally specify a number of seconds to wait by 'data=N' where N is the number of seconds. Defaults to 30 if not specified. See the tcp(7) man page for details. EXAMPLE: # FreeBSD accept_filter httpready # Linux accept_filter data DOC_END NAME: client_ip_max_connections TYPE: int LOC: Config.client_ip_max_connections DEFAULT: -1 DEFAULT_DOC: No limit. DOC_START Set an absolute limit on the number of connections a single client IP can use. Any more than this and Squid will begin to drop new connections from the client until it closes some links. Note that this is a global limit. It affects all HTTP, HTCP, Gopher and FTP connections from the client. For finer control use the ACL access controls. Requires client_db to be enabled (the default). WARNING: This may noticably slow down traffic received via external proxies or NAT devices and cause them to rebound error messages back to their clients.

DOC_END NAME: icap_connect_timeout TYPE: time_t DEFAULT: none LOC: Adaptation::Icap::TheConfig.connect_timeout_raw IFDEF: ICAP_CLIENT DOC_START This parameter specifies how long to wait for the TCP connect to the requested ICAP server to complete before giving up and either terminating the HTTP transaction or bypassing the failure. The default for optional services is peer_connect_timeout. The default for essential services is connect_timeout. If this option is explicitly set, its value applies to all services. DOC_END NAME: icap_io_timeout COMMENT: time-units TYPE: time_t DEFAULT: none DEFAULT_DOC: Use read_timeout. LOC: Adaptation::Icap::TheConfig.io_timeout_raw IFDEF: ICAP_CLIENT DOC_START This parameter specifies how long to wait for an I/O activity on an established, active ICAP connection before giving up and either terminating the HTTP transaction or bypassing the failure. DOC_END NAME: icap_service_failure_limit COMMENT: limit [in memory-depth time-units] TYPE: icap_service_failure_limit IFDEF: ICAP_CLIENT LOC: Adaptation::Icap::TheConfig DEFAULT: 10 DOC_START The limit specifies the number of failures that Squid tolerates when establishing a new TCP connection with an ICAP service. If the number of failures exceeds the limit, the ICAP service is not used for new ICAP requests until it is time to refresh its OPTIONS. A negative value disables the limit. Without the limit, an ICAP service will not be considered down due to connectivity failures between ICAP OPTIONS requests. Squid forgets ICAP service failures older than the specified value of memory-depth. The memory fading algorithm is approximate because Squid does not remember individual errors but groups them instead, splitting the option value into ten time slots of equal length. When memory-depth is 0 and by default this option has no effect on service failure expiration. Squid always forgets failures when updating service settings using an ICAP OPTIONS transaction, regardless of this option setting. For example, # suspend service usage after 10 failures in 5 seconds: icap_service_failure_limit 10 in 5 seconds DOC_END NAME: icap_service_revival_delay TYPE: int IFDEF: ICAP_CLIENT LOC: Adaptation::Icap::TheConfig.service_revival_delay DEFAULT: 180 DOC_START The delay specifies the number of seconds to wait after an ICAP OPTIONS request failure before requesting the options again. The failed ICAP service is considered "down" until fresh OPTIONS are fetched. The actual delay cannot be smaller than the hardcoded minimum delay of 30 seconds. DOC_END NAME: icap_preview_enable TYPE: onoff IFDEF: ICAP_CLIENT COMMENT: on|off LOC: Adaptation::Icap::TheConfig.preview_enable DEFAULT: on DOC_START The ICAP Preview feature allows the ICAP server to handle the HTTP message by looking only at the beginning of the message body or even without receiving the body at all. In some environments, previews greatly speedup ICAP processing. During an ICAP OPTIONS transaction, the server may tell Squid what HTTP messages should be previewed and how big the preview should be. Squid will not use Preview if the server did not request one. To disable ICAP Preview for all ICAP services, regardless of individual ICAP server OPTIONS responses, set this option to "off". Example: icap_preview_enable off DOC_END NAME: icap_preview_size TYPE: int IFDEF: ICAP_CLIENT LOC: Adaptation::Icap::TheConfig.preview_size DEFAULT: -1 DEFAULT_DOC: No preview sent. DOC_START The default size of preview data to be sent to the ICAP server. This value might be overwritten on a per server basis by OPTIONS requests. DOC_END NAME: icap_206_enable TYPE: onoff IFDEF: ICAP_CLIENT COMMENT: on|off LOC: Adaptation::Icap::TheConfig.allow206_enable DEFAULT: on DOC_START 206 (Partial Content) responses is an ICAP extension that allows the ICAP agents to optionally combine adapted and original HTTP message content. The decision to combine is postponed until the end of the ICAP response. Squid supports Partial Content extension by default. Activation of the Partial Content extension is negotiated with each ICAP service during OPTIONS exchange. Most ICAP servers should handle negotation correctly even if they do not support the extension, but some might fail. To disable Partial Content support for all ICAP services and to avoid any negotiation, set this option to "off". Example: icap_206_enable off DOC_END NAME: icap_default_options_ttl TYPE: int IFDEF: ICAP_CLIENT LOC: Adaptation::Icap::TheConfig.default_options_ttl DEFAULT: 60 DOC_START The default TTL value for ICAP OPTIONS responses that don't have an Options-TTL header.

DOC_END NAME: icap_service TYPE: icap_service_type IFDEF: ICAP_CLIENT LOC: Adaptation::Icap::TheConfig DEFAULT: none DOC_START Defines a single ICAP service using the following format: icap_service id vectoring_point uri [option ...] id: ID an opaque identifier or name which is used to direct traffic to this specific service. Must be unique among all adaptation services in squid.conf. vectoring_point: reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache This specifies at which point of transaction processing the ICAP service should be activated. *_postcache vectoring points are not yet supported. uri: icap://servername:port/servicepath ICAP server and service location. ICAP does not allow a single service to handle both REQMOD and RESPMOD transactions. Squid does not enforce that requirement. You can specify services with the same service_url and different vectoring_points. You can even specify multiple identical services as long as their service_names differ. To activate a service, use the adaptation_access directive. To group services, use adaptation_service_chain and adaptation_service_set. Service options are separated by white space. ICAP services support the following name=value options: bypass=on|off|1|0 If set to 'on' or '1', the ICAP service is treated as optional. If the service cannot be reached or malfunctions, Squid will try to ignore any errors and process the message as if the service was not enabled. No all ICAP errors can be bypassed. If set to 0, the ICAP service is treated as essential and all ICAP errors will result in an error page returned to the HTTP client. Bypass is off by default: services are treated as essential. routing=on|off|1|0 If set to 'on' or '1', the ICAP service is allowed to dynamically change the current message adaptation plan by returning a chain of services to be used next. The services are specified using the X-Next-Services ICAP response header value, formatted as a comma-separated list of service names. Each named service should be configured in squid.conf. Other services are ignored. An empty X-Next-Services value results in an empty plan which ends the current adaptation. Dynamic adaptation plan may cross or cover multiple supported vectoring points in their natural processing order. Routing is not allowed by default: the ICAP X-Next-Services response header is ignored. ipv6=on|off Only has effect on split-stack systems. The default on those systems is to use IPv4-only connections. When set to 'on' this option will make Squid use IPv6-only connections to contact this ICAP service. on-overload=block|bypass|wait|force If the service Max-Connections limit has been reached, do one of the following for each new ICAP transaction: * block: send an HTTP error response to the client * bypass: ignore the "over-connected" ICAP service * wait: wait (in a FIFO queue) for an ICAP connection slot * force: proceed, ignoring the Max-Connections limit In SMP mode with N workers, each worker assumes the service connection limit is Max-Connections/N, even though not all workers may use a given service. The default value is "bypass" if service is bypassable, otherwise it is set to "wait". max-conn=number Use the given number as the Max-Connections limit, regardless of the Max-Connections value given by the service, if any. Older icap_service format without optional named parameters is deprecated but supported for backward compatibility. Example: icap_service svcBlocker reqmod_precache icap://icap1.mydomain.net:1344/reqmod bypass=0 icap_service svcLogger reqmod_precache icap://icap2.mydomain.net:1344/respmod routing=on DOC_END NAME: icap_class TYPE: icap_class_type IFDEF: ICAP_CLIENT LOC: none DEFAULT: none DOC_START This deprecated option was documented to define an ICAP service chain, even though it actually defined a set of similar, redundant services, and the chains were not supported.

Must be unique among all adaptation services in squid.conf. vectoring_point: reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache This specifies at which point of transaction processing the eCAP service should be activated. *_postcache vectoring points are not yet supported. uri: ecap://vendor/service_name?custom&cgi=style¶meters=optional Squid uses the eCAP service URI to match this configuration line with one of the dynamically loaded services. Each loaded eCAP service must have a unique URI. Obtain the right URI from the service provider. To activate a service, use the adaptation_access directive. To group services, use adaptation_service_chain and adaptation_service_set. Service options are separated by white space. eCAP services support the following name=value options: bypass=on|off|1|0 If set to 'on' or '1', the eCAP service is treated as optional. If the service cannot be reached or malfunctions, Squid will try to ignore any errors and process the message as if the service was not enabled. No all eCAP errors can be bypassed. If set to 'off' or '0', the eCAP service is treated as essential and all eCAP errors will result in an error page returned to the HTTP client. Bypass is off by default: services are treated as essential. routing=on|off|1|0 If set to 'on' or '1', the eCAP service is allowed to dynamically change the current message adaptation plan by returning a chain of services to be used next. Dynamic adaptation plan may cross or cover multiple supported vectoring points in their natural processing order. Routing is not allowed by default. Older ecap_service format without optional named parameters is deprecated but supported for backward compatibility.

This is useful when hot standby or backup adaptation servers are available. adaptation_service_set set_name service_name1 service_name2 ... The named services are used in the set declaration order. The first applicable adaptation service from the set is used first. The next applicable service is tried if and only if the transaction with the previous service fails and the message waiting to be adapted is still intact. When adaptation starts, broken services are ignored as if they were not a part of the set. A broken service is a down optional service. The services in a set must be attached to the same vectoring point (e.g., pre-cache) and use the same adaptation method (e.g., REQMOD). If all services in a set are optional then adaptation failures are bypassable. If all services in the set are essential, then a transaction failure with one service may still be retried using another service from the set, but when all services fail, the master transaction fails as well. A set may contain a mix of optional and essential services, but that is likely to lead to surprising results because broken services become ignored (see above), making previously bypassable failures fatal. Technically, it is the bypassability of the last failed service that matters. See also: adaptation_access adaptation_service_chain Example: adaptation_service_set svcBlocker urlFilterPrimary urlFilterBackup adaptation service_set svcLogger loggerLocal loggerRemote DOC_END NAME: adaptation_service_chain TYPE: adaptation_service_chain_type IFDEF: USE_ADAPTATION LOC: none DEFAULT: none DOC_START Configures a list of complementary services that will be applied one-by-one, forming an adaptation chain or pipeline. This is useful when Squid must perform different adaptations on the same message. adaptation_service_chain chain_name service_name1 svc_name2 ... The named services are used in the chain declaration order. The first applicable adaptation service from the chain is used first. The next applicable service is applied to the successful adaptation results of the previous service in the chain. When adaptation starts, broken services are ignored as if they were not a part of the chain. A broken service is a down optional service. Request satisfaction terminates the adaptation chain because Squid does not currently allow declaration of RESPMOD services at the "reqmod_precache" vectoring point (see icap_service or ecap_service). The services in a chain must be attached to the same vectoring point (e.g., pre-cache) and use the same adaptation method (e.g., REQMOD). A chain may contain a mix of optional and essential services. If an essential adaptation fails (or the failure cannot be bypassed for other reasons), the master transaction fails. Otherwise, the failure is bypassed as if the failed adaptation service was not in the chain.

At each supported vectoring point, the adaptation_access statements are processed in the order they appear in this configuration file. Statements pointing to the following services are ignored (i.e., skipped without checking their ACL): - services serving different vectoring points - "broken-but-bypassable" services - "up" services configured to ignore such transactions (e.g., based on the ICAP Transfer-Ignore header). When a set_name is used, all services in the set are checked using the same rules, to find the first applicable one. See adaptation_service_set for details. If an access list is checked and there is a match, the processing stops: For an "allow" rule, the corresponding adaptation service is used for the transaction. For a "deny" rule, no adaptation service is activated. It is currently not possible to apply more than one adaptation service at the same vectoring point to the same HTTP transaction.

If your longest adaptation set or chain may have more than 16 services, increase the limit beyond its default value of 16. If detecting infinite iteration loops sooner is critical, make the iteration limit match the actual number of services in your longest adaptation set or chain. Infinite adaptation loops are most likely with routing services. See also: icap_service routing=1 DOC_END NAME: adaptation_masterx_shared_names TYPE: string IFDEF: USE_ADAPTATION LOC: Adaptation::Config::masterx_shared_name DEFAULT: none DOC_START For each master transaction (i.e., the HTTP request and response sequence, including all related ICAP and eCAP exchanges), Squid maintains a table of metadata. The table entries are (name, value) pairs shared among eCAP and ICAP exchanges. The table is destroyed with the master transaction. This option specifies the table entry names that Squid must accept from and forward to the adaptation transactions. An ICAP REQMOD or RESPMOD transaction may set an entry in the shared table by returning an ICAP header field with a name specified in adaptation_masterx_shared_names. An eCAP REQMOD or RESPMOD transaction may set an entry in the shared table by implementing the libecap::visitEachOption() API to provide an option with a name specified in adaptation_masterx_shared_names. Squid will store and forward the set entry to subsequent adaptation transactions within the same master transaction scope. Only one shared entry name is supported at this time. Example: # share authentication information among ICAP services adaptation_masterx_shared_names X-Subscriber-ID DOC_END NAME: adaptation_meta TYPE: note IFDEF: USE_ADAPTATION LOC: Adaptation::Config::metaHeaders DEFAULT: none DOC_START This option allows Squid administrator to add custom ICAP request headers or eCAP options to Squid ICAP requests or eCAP transactions. Use it to pass custom authentication tokens and other transaction-state related meta information to an ICAP/eCAP service. The addition of a meta header is ACL-driven: adaptation_meta name value [!]aclname ... Processing for a given header name stops after the first ACL list match. Thus, it is impossible to add two headers with the same name. If no ACL lists match for a given header name, no such header is added. For example: # do not debug transactions except for those that need debugging adaptation_meta X-Debug 1 needs_debugging # log all transactions except for those that must remain secret adaptation_meta X-Log 1 !keep_secret # mark transactions from users in the "G 1" group adaptation_meta X-Authenticated-Groups "G 1" authed_as_G1 The "value" parameter may be a regular squid.conf token or a "double quoted string". Within the quoted string, use backslash (\) to escape any character, which is currently only useful for escaping backslashes and double quotes. For example, "this string has one backslash (\\) and two \"quotes\"" Used adaptation_meta header values may be logged via %note logformat code. If multiple adaptation_meta headers with the same name are used during master transaction lifetime, the header values are logged in the order they were used and duplicate values are ignored (only the first repeated value will be logged).

Set to "none" to disable EDNS large packet support. For legacy reasons DNS UDP replies will default to 512 bytes which is too small for many responses. EDNS provides a means for Squid to negotiate receiving larger responses back immediately without having to failover with repeat requests. Responses larger than this limit will retain the old behaviour of failover to TCP DNS. Squid has no real fixed limit internally, but allowing packet sizes over 1500 bytes requires network jumbogram support and is usually not necessary. WARNING: The RFC also indicates that some older resolvers will reply with failure of the whole request if the extension is added. Some resolvers have already been identified which will reply with mangled EDNS response on occasion. Usually in response to many-KB jumbogram sizes being advertised by Squid. Squid will currently treat these both as an unable-to-resolve domain even if it would be resolvable without EDNS. DOC_END NAME: dns_defnames COMMENT: on|off TYPE: onoff DEFAULT: off DEFAULT_DOC: Search for single-label domain names is disabled. LOC: Config.onoff.res_defnames DOC_START Normally the RES_DEFNAMES resolver option is disabled (see res_init(3)).

Lines beginning with an hash (#) character are comments. The file is checked at startup and upon configuration. If set to 'none', it won't be checked. If append_domain is used, that domain will be added to domain-local (i.e. not containing any dot character) host definitions. DOC_END NAME: append_domain TYPE: string LOC: Config.appendDomain DEFAULT: none DEFAULT_DOC: Use operating system definitions DOC_START Appends local domain name to hostnames without any dots in them. append_domain must begin with a period.

Example: append_domain .yourdomain.com DOC_END NAME: ignore_unknown_nameservers TYPE: onoff LOC: Config.onoff.ignore_unknown_nameservers DEFAULT: on DOC_START By default Squid checks that DNS responses are received from the same IP addresses they are sent to. If they don't match, Squid ignores the response and writes a warning message to cache.log. You can allow responses from unknown nameservers by setting this option to 'off'. DOC_END NAME: dns_v4_first TYPE: onoff DEFAULT: off LOC: Config.dns.v4_first DOC_START With the IPv6 Internet being as fast or faster than IPv4 Internet for most networks Squid prefers to contact websites over IPv6. This option reverses the order of preference to make Squid contact dual-stack websites over IPv4 first. Squid will still perform both IPv6 and IPv4 DNS lookups before connecting. WARNING: This option will restrict the situations under which IPv6 connectivity is used (and tested). Hiding network problems which would otherwise be detected and warned about.

DOC_END NAME: memory_pools COMMENT: on|off TYPE: onoff DEFAULT: on LOC: Config.onoff.mem_pools DOC_START If set, Squid will keep pools of allocated (but unused) memory available for future use. If memory is a premium on your system and you believe your malloc library outperforms Squid routines, disable this. DOC_END NAME: memory_pools_limit COMMENT: (bytes) TYPE: b_int64_t DEFAULT: 5 MB LOC: Config.MemPools.limit DOC_START Used only with memory_pools on: memory_pools_limit 50 MB If set to a non-zero value, Squid will keep at most the specified limit of allocated (but unused) memory in memory pools. All free() requests that exceed this limit will be handled by your malloc library. Squid does not pre-allocate any memory, just safe-keeps objects that otherwise would be free()d. Thus, it is safe to set memory_pools_limit to a reasonably high value even if your configuration will use less memory. If set to none, Squid will keep all memory it can. That is, there will be no limit on the total amount of memory used for safe-keeping. To disable memory allocation optimization, do not set memory_pools_limit to 0 or none. Set memory_pools to "off" instead. An overhead for maintaining memory pools is not taken into account when the limit is checked. This overhead is close to four bytes per object kept. However, pools may actually _save_ memory because of reduced memory thrashing in your malloc library. DOC_END NAME: forwarded_for COMMENT: on|off|transparent|truncate|delete TYPE: string DEFAULT: on LOC: opt_forwarded_for DOC_START If set to "on", Squid will append your client's IP address in the HTTP requests it forwards. By default it looks like: X-Forwarded-For: 192.1.2.3 If set to "off", it will appear as X-Forwarded-For: unknown If set to "transparent", Squid will not alter the X-Forwarded-For header in any way. If set to "delete", Squid will delete the entire X-Forwarded-For header. If set to "truncate", Squid will remove all existing X-Forwarded-For entries, and place the client IP as the sole entry.

Many browsers use IMS requests when the user requests a reload, and this ensures those clients receive the latest version. By default (off), squid may return a Not Modified response based on the age of the cached version. DOC_END NAME: reload_into_ims IFDEF: USE_HTTP_VIOLATIONS COMMENT: on|off TYPE: onoff DEFAULT: off LOC: Config.onoff.reload_into_ims DOC_START When you enable this option, client no-cache or ``reload'' requests will be changed to If-Modified-Since requests. Doing this VIOLATES the HTTP standard. Enabling this feature could make you liable for problems which it causes. see also refresh_pattern for a more selective approach. DOC_END NAME: connect_retries TYPE: int LOC: Config.connect_retries DEFAULT: 0 DEFAULT_DOC: Do not retry failed connections. DOC_START This sets the maximum number of connection attempts made for each TCP connection. The connect_retries attempts must all still complete within the connection timeout period. The default is not to re-try if the first connection attempt fails. The (not recommended) maximum is 10 tries. A warning message will be generated if it is set to a too-high value and the configured value will be over-ridden. Note: These re-tries are in addition to forward_max_tries which limit how many different addresses may be tried to find a useful server. DOC_END NAME: retry_on_error TYPE: onoff LOC: Config.retry.onerror DEFAULT: off DOC_START If set to ON Squid will automatically retry requests when receiving an error response with status 403 (Forbidden), 500 (Internal Error), 501 or 503 (Service not available). Status 502 and 504 (Gateway errors) are always retried. This is mainly useful if you are in a complex cache hierarchy to work around access control errors. NOTE: This retry will attempt to find another working destination. Which is different from the server which just failed. DOC_END NAME: as_whois_server TYPE: string LOC: Config.as_whois_server DEFAULT: whois.ra.net DOC_START WHOIS server to query for AS numbers. NOTE: AS numbers are queried only when Squid starts up, not for every request. DOC_END NAME: offline_mode TYPE: onoff LOC: Config.onoff.offline DEFAULT: off DOC_START Enable this option and Squid will never try to validate cached objects. DOC_END NAME: uri_whitespace TYPE: uri_whitespace LOC: Config.uri_whitespace DEFAULT: strip DOC_START What to do with requests that have whitespace characters in the URI. Options: strip: The whitespace characters are stripped out of the URL. This is the behavior recommended by RFC2396 and RFC3986 for tolerant handling of generic URI. NOTE: This is one difference between generic URI and HTTP URLs. deny: The request is denied. The user receives an "Invalid Request" message. This is the behaviour recommended by RFC2616 for safe handling of HTTP request URL. allow: The request is allowed and the URI is not changed. The whitespace characters remain in the URI. Note the whitespace is passed to redirector processes if they are in use. Note this may be considered a violation of RFC2616 request parsing where whitespace is prohibited in the URL field. encode: The request is allowed and the whitespace characters are encoded according to RFC1738. chop: The request is allowed and the URI is chopped at the first whitespace. NOTE the current Squid implementation of encode and chop violates RFC2616 by not using a 301 redirect after altering the URL. DOC_END NAME: chroot TYPE: string LOC: Config.chroot_dir DEFAULT: none DOC_START Specifies a directory where Squid should do a chroot() while initializing. This also causes Squid to fully drop root privileges after initializing. This means, for example, if you use a HTTP port less than 1024 and try to reconfigure, you may get an error saying that Squid can not open the port. DOC_END NAME: balance_on_multiple_ip TYPE: onoff LOC: Config.onoff.balance_on_multiple_ip DEFAULT: off DOC_START Modern IP resolvers in squid sort lookup results by preferred access. By default squid will use these IP in order and only rotates to the next listed when the most preffered fails. Some load balancing servers based on round robin DNS have been found not to preserve user session state across requests to different IP addresses. Enabling this directive Squid rotates IP's per request. DOC_END NAME: pipeline_prefetch TYPE: pipelinePrefetch LOC: Config.pipeline_max_prefetch DEFAULT: 0 DEFAULT_DOC: Do not pre-parse pipelined requests. DOC_START HTTP clients may send a pipeline of 1+N requests to Squid using a single connection, without waiting for Squid to respond to the first of those requests. This option limits the number of concurrent requests Squid will try to handle in parallel. If set to N, Squid will try to receive and process up to 1+N requests on the same connection concurrently. Defaults to 0 (off) for bandwidth management and access logging reasons. NOTE: pipelining requires persistent connections to clients. WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication. DOC_END NAME: high_response_time_warning TYPE: int COMMENT: (msec) LOC: Config.warnings.high_rptm DEFAULT: 0 DEFAULT_DOC: disabled. DOC_START If the one-minute median response time exceeds this value, Squid prints a WARNING with debug level 0 to get the administrators attention. The value is in milliseconds. DOC_END NAME: high_page_fault_warning TYPE: int LOC: Config.warnings.high_pf DEFAULT: 0 DEFAULT_DOC: disabled. DOC_START If the one-minute average page fault rate exceeds this value, Squid prints a WARNING with debug level 0 to get the administrators attention. The value is in page faults per second. DOC_END NAME: high_memory_warning TYPE: b_size_t LOC: Config.warnings.high_memory IFDEF: HAVE_MSTATS&&HAVE_GNUMALLOC_H DEFAULT: 0 KB DEFAULT_DOC: disabled. DOC_START If the memory usage (as determined by gnumalloc, if available and used) exceeds this amount, Squid prints a WARNING with debug level 0 to get the administrators attention. DOC_END # TODO: link high_memory_warning to mempools? NAME: sleep_after_fork COMMENT: (microseconds) TYPE: int LOC: Config.sleep_after_fork DEFAULT: 0 DOC_START When this is set to a non-zero value, the main Squid process sleeps the specified number of microseconds after a fork() system call. This sleep may help the situation where your system reports fork() failures due to lack of (virtual) memory. Note, however, if you have a lot of child processes, these sleep delays will add up and your Squid will not service requests for some amount of time until all the child processes have been started. On Windows value less then 1000 (1 milliseconds) are rounded to 1000. DOC_END NAME: windows_ipaddrchangemonitor IFDEF: _SQUID_WINDOWS_ COMMENT: on|off TYPE: onoff DEFAULT: on LOC: Config.onoff.WIN32_IpAddrChangeMonitor DOC_START On Windows Squid by default will monitor IP address changes and will reconfigure itself after any detected event. This is very useful for proxies connected to internet with dial-up interfaces. In some cases (a Proxy server acting as VPN gateway is one) it could be desiderable to disable this behaviour setting this to 'off'. Note: after changing this, Squid service must be restarted. DOC_END NAME: eui_lookup TYPE: onoff IFDEF: USE_SQUID_EUI DEFAULT: on LOC: Eui::TheConfig.euiLookup DOC_START Whether to lookup the EUI or MAC address of a connected client. DOC_END NAME: max_filedescriptors max_filedesc TYPE: int DEFAULT: 0 DEFAULT_DOC: Use operating system limits set by ulimit. LOC: Config.max_filedescriptors DOC_START Reduce the maximum number of filedescriptors supported below the usual operating system defaults. Remove from squid.conf to inherit the current ulimit setting. Note: Changing this requires a restart of Squid. Also not all I/O types supports large values (eg on Windows).

This allows the callbacks to be changed * very easily by a participating node, but requires more maintenance * in each node (store the callback to the most recent IO request in * the nodes context.) Such an approach also prevents dynamically * changing the pipeline from outside without an additional interface * method to extract the callback and context from the next node. * \par * One important characteristic of the stream is that the readfunc * on the terminating node, and the callback on the first node * will be NULL, and never used. * \section QuickNotes Quick Notes \par * Each node including the HEAD of the clientStream has a cbdataReference * held by the stream. Freeing the stream then removes that reference * and cbdataFree()'s every node. * Any node with other References, and all nodes downstream will only * free when those references are released. * Stream nodes MAY hold references to the data member of the node. * \par * Specifically - on creation no reference is made. * If you pass a data variable to a node, give it an initial reference. * If the data member is non-null on FREE, cbdataFree WILL be called. * This you must never call cbdataFree on your own context without * explicitly setting the stream node data member to NULL and * cbdataReferenceDone'ing it. * \par * No data member may hold a reference to it's stream node. * The stream guarantees that DETACH will be called before * freeing the node, alowing data members to cleanup. * \par * If a node's data holds a reference to something that needs to * free the stream a circular reference list will occur. * This results no data being freed until that reference is removed. * One way to accomplish thisObject is to explicitly remove the * data from your own node before freeing the stream. * \code mycontext = thisObject->data; thisObject->data = NULL; clientStreamFree (thisObject->head); mycontext = NULL; return; \endcode * \todo rather than each node undeleting the next, have a clientStreamDelete that walks the list. */ /// \ingroup ClientStreamInternal CBDATA_TYPE(clientStreamNode); /* Local functions */ static FREE clientStreamFree; /// \ingroup ClientStreamInternal clientStreamNode * clientStreamNew(CSR * readfunc, CSCB * callback, CSD * detach, CSS * status, ClientStreamData data) { clientStreamNode *temp; CBDATA_INIT_TYPE_FREECB(clientStreamNode, clientStreamFree); temp = cbdataAlloc(clientStreamNode); temp->readfunc = readfunc; temp->callback = callback; temp->detach = detach; temp->status = status; temp->data = data; return temp; } /** \ingroup ClientStreamInternal * Initialise a client Stream. * list is the stream * func is the read function for the head * callback is the callback for the tail * tailbuf and taillen are the initial buffer and length for the tail. */ void clientStreamInit(dlink_list * list, CSR * func, CSD * rdetach, CSS * readstatus, ClientStreamData readdata, CSCB * callback, CSD * cdetach, ClientStreamData callbackdata, StoreIOBuffer tailBuffer) { clientStreamNode *temp = clientStreamNew(func, NULL, rdetach, readstatus, readdata); dlinkAdd(cbdataReference(temp), &temp->node, list); temp->head = list; clientStreamInsertHead(list, NULL, callback, cdetach, NULL, callbackdata); temp = (clientStreamNode *)list->tail->data; temp->readBuffer = tailBuffer; } /** \ingroup ClientStreamInternal * Doesn't actually insert at head.

They allow code to be inserted into the * reply logic on an as-needed basis. For instance, * transfer-encoding logic is only needed when sending a * HTTP/1.1 reply. * \par * Each node consists of four methods - read, callback, detach, and status, * along with the stream housekeeping variables (a dlink node and pointer * to the head of the list), context data for the node, and read request * parameters - readbuf, readlen and readoff (in the body). * \par * clientStream is the basic unit for scheduling, and the clientStreamRead() * and clientStreamCallback() calls allow for deferred scheduled activity if * desired. * \section OperationTheory Theory on stream operation \par \li Something creates a pipeline. At a minimum it needs a head with a * status method and a read method, and a tail with a callback method * and a valid initial read request. \li Other nodes may be added into the pipeline. \li The tail-1th node's read method is called. * \par * For each node going up the pipeline, the node either: \li satisfies the read request, or \li inserts a new node above it and calls clientStreamRead(), or \li calls clientStreamRead() \todo DOCS: make the above list nested. * \par * There is no requirement for the Read parameters from different * nodes to have any correspondence, as long as the callbacks provided are * correct. * \section WhatsInANode Whats in a node * \todo ClientStreams: These details should really be codified as a class which all ClientStream nodes inherit from. * \par Each node must have: \li read method - to allow loose coupling in the pipeline. (The reader may therefore change if the pipeline is altered, even mid-flow). \li callback method - likewise. \li status method - likewise. \li detach method - used to ensure all resources are cleaned up properly. \li dlink head pointer - to allow list inserts and deletes from within a node. \li context data - to allow the called back nodes to maintain their private information. \li read request parameters - For two reasons: \li To allow a node to determine the requested data offset, length and target buffer dynamically. Again, this is to promote loose coupling. \li Because of the callback nature of squid, every node would have to keep these parameters in their context anyway, so this reduces programmer overhead. */ /// \ingroup ClientStreamAPI class clientStreamNode { public: clientStreamNode *prev() const; clientStreamNode *next() const; void removeFromStream(); dlink_node node; dlink_list *head; /* sucks I know, but hey, the interface is limited */ CSR *readfunc; CSCB *callback; CSD *detach; /* tell this node the next one downstream wants no more data */ CSS *status; ClientStreamData data; /* Context for the node */ StoreIOBuffer readBuffer; /* what, where and how much this node wants */ }; /// \ingroup ClientStreamAPI void clientStreamInit(dlink_list *, CSR *, CSD *, CSS *, ClientStreamData, CSCB *, CSD *, ClientStreamData, StoreIOBuffer tailBuffer); /// \ingroup ClientStreamAPI void clientStreamInsertHead(dlink_list *, CSR *, CSCB *, CSD *, CSS *, ClientStreamData); /// \ingroup ClientStreamAPI clientStreamNode *clientStreamNew(CSR *, CSCB *, CSD *, CSS *, ClientStreamData); /** \ingroup ClientStreamAPI * * Call back the next node the in chain with it's requested data. * Return data to the next node in the stream. * The data may be returned immediately, or may be delayed for a later scheduling cycle. * \param thisObject 'this' reference for the client stream \param http Superset of request data, being winnowed down over time.

If a * routine coredumps, one can restore the context using debugger trace. * However, in many case you do not want to coredump, but just want to report * a potential problem. A report maybe useless out of problem context. * * To solve this potential problem, use the following approach: * * int * top_level_foo(const char *url) * { * // define current context * // note: we stack but do not dup ctx descriptions! * Ctx ctx = ctx_enter(url); * ... * // go down; middle_level_bar will eventually call bottom_level_boo * middle_level_bar(method, protocol); * ... * // exit, clean after yourself * ctx_exit(ctx); * } * * void * bottom_level_boo(int status, void *data) * { * // detect exceptional condition, and simply report it, the context * // information will be available somewhere close in the log file * if (status == STRANGE_STATUS) * debugs(13, 6, "DOS attack detected, data: " << data); * ... * } * * Current implementation is extremely simple but still very handy. It has a * negligible overhead (descriptions are not duplicated). * * When the _first_ debug message for a given context is printed, it is * prepended with the current context description. Context is printed with * the same debugging level as the original message. * * Note that we do not print context every type you do ctx_enter(). This * approach would produce too many useless messages. For the same reason, a * context description is printed at most _once_ even if you have 10 * debugging messages within one context. * * Contexts can be nested, of course. You must use ctx_enter() to enter a * context (push it onto stack). It is probably safe to exit several nested * contexts at _once_ by calling ctx_exit() at the top level (this will pop * all context till current one). However, as in any stack, you cannot start * in the middle. * * Analysis: * i) locate debugging message, * ii) locate current context by going _upstream_ in your log file, * iii) hack away. * * * To-Do: * ----- * * decide if we want to dup() descriptions (adds overhead) but allows to * add printf()-style interface * * implementation: * --------------- * * descriptions for contexts over CTX_MAX_LEVEL limit are ignored, you probably * have a bug if your nesting goes that deep. */ #define CTX_MAX_LEVEL 255 /* * produce a warning when nesting reaches this level and then double * the level */ static int Ctx_Warn_Level = 32; /* all descriptions has been printed up to this level */ static int Ctx_Reported_Level = -1; /* descriptions are still valid or active up to this level */ static int Ctx_Valid_Level = -1; /* current level, the number of nested ctx_enter() calls */ static int Ctx_Current_Level = -1; /* saved descriptions (stack) */ static const char *Ctx_Descrs[CTX_MAX_LEVEL + 1]; /* "safe" get secription */ static const char *ctx_get_descr(Ctx ctx); Ctx ctx_enter(const char *descr) { ++Ctx_Current_Level; if (Ctx_Current_Level <= CTX_MAX_LEVEL) Ctx_Descrs[Ctx_Current_Level] = descr; if (Ctx_Current_Level == Ctx_Warn_Level) { debugs(0, DBG_CRITICAL, "# ctx: suspiciously deep (" << Ctx_Warn_Level << ") nesting:"); Ctx_Warn_Level *= 2; } return Ctx_Current_Level; } void ctx_exit(Ctx ctx) { assert(ctx >= 0); Ctx_Current_Level = (ctx >= 0) ? ctx - 1 : -1; if (Ctx_Valid_Level > Ctx_Current_Level) Ctx_Valid_Level = Ctx_Current_Level; } /* * the idea id to print each context description at most once but provide enough * info for deducing the current execution stack */ static void ctx_print(void) { /* lock so _db_print will not call us recursively */ ++Ctx_Lock; /* ok, user saw [0,Ctx_Reported_Level] descriptions */ /* first inform about entries popped since user saw them */ if (Ctx_Valid_Level < Ctx_Reported_Level) { if (Ctx_Reported_Level != Ctx_Valid_Level + 1) _db_print("ctx: exit levels from %2d down to %2d\n", Ctx_Reported_Level, Ctx_Valid_Level + 1); else _db_print("ctx: exit level %2d\n", Ctx_Reported_Level); Ctx_Reported_Level = Ctx_Valid_Level; } /* report new contexts that were pushed since last report */ while (Ctx_Reported_Level < Ctx_Current_Level) { ++Ctx_Reported_Level; ++Ctx_Valid_Level; _db_print("ctx: enter level %2d: '%s'\n", Ctx_Reported_Level, ctx_get_descr(Ctx_Reported_Level)); } /* unlock */ --Ctx_Lock; } /* checks for nulls and overflows */ static const char * ctx_get_descr(Ctx ctx) { if (ctx < 0 || ctx > CTX_MAX_LEVEL) return ""; return Ctx_Descrs[ctx] ?

/** \defgroup RockFsRebuild Rock Store Rebuild \ingroup Filesystems * \section Overview Overview * Several layers of information are manipualted during the rebuild: \par * Store Entry: Response message plus all the metainformation associated with * it. Identified by store key. At any given time, from Squid point * of view, there is only one entry with a given key, but several * different entries with the same key can be observed in any historical * archive (such as an access log or a store database). \par * Slot chain: A sequence of db slots representing a Store Entry state at * some point in time. Identified by key+version combination. Due to * transaction aborts, crashes, and idle periods, some chains may contain * incomplete or stale information. We assume that no two different chains * have the same key and version. If that assumption fails, we may serve a * hodgepodge entry during rebuild, until "extra" slots are loaded/noticed. \par * Db slot: A db record containing a piece of a single store entry and linked * to other slots with the same key and version fields, forming a chain. * Slots are identified by their absolute position in the database file, * which is naturally unique. \par * Except for the "mapped", "freed", and "more" fields, LoadingEntry info is * entry-level and is stored at fileno position. In other words, the array of * LoadingEntries should be interpreted as two arrays, one that maps slot ID * to the LoadingEntry::mapped/free/more members, and the second one that maps * fileno to all other LoadingEntry members. StoreMap maps slot key to fileno. \par * When information from the newly loaded db slot contradicts the entry-level * information collected so far (e.g., the versions do not match or the total * chain size after the slot contribution exceeds the expected number), the * whole entry (and not just the chain or the slot!) is declared corrupted. \par * Why invalidate the whole entry? Rock Store is written for high-load * environments with large caches, where there is usually very few idle slots * in the database. A space occupied by a purged entry is usually immediately * reclaimed. A Squid crash or a transaction abort is rather unlikely to * leave a relatively large number of stale slots in the database. Thus, the * number of potentially corrupted entries is relatively small. On the other * hand, the damage from serving a single hadgepodge entry may be significant * to the user. In such an environment, invalidating the whole entry has * negligible performance impact but saves us from high-damage bugs. */ namespace Rock { /// maintains information about the store entry being loaded from disk /// used for identifying partially stored/loaded entries class LoadingEntry { public: LoadingEntry(): size(0), version(0), state(leEmpty), anchored(0), mapped(0), freed(0), more(-1) {} /* store entry-level information indexed by sfileno */ uint64_t size;

#define SQUID_HELPER 1

/**
 \defgroup pinger pinger
 \ingroup ExternalPrograms
 \par
 *   Although it would be possible for Squid to send and receive
 *   ICMP messages directly, we use an external process for
 *   two important reasons:
 *
 \li Because squid handles many filedescriptors simultaneously,
 *   we get much more accurate RTT measurements when ICMP is
 *   handled by a separate process.
 *
 \li Superuser privileges are required to send and receive ICMP.
 *   Rather than require Squid to be started as root, we prefer
 *   to have the smaller and simpler pinger program installed
 *   with setuid permissions.
 *
 \par
 *   If you want to use Squid's ICMP features (highly recommended!)
 *   When USE_ICMP is defined, Squid will send ICMP pings
 *   to origin server sites.
 *   This information is used in numerous ways:
 \li  - Sent in ICP replies so neighbor caches know how close
 *      you are to the source.
 \li  - For finding the closest instance of a URN.
 \li  - With the 'test_reachability' option.  Squid will return
 *      ICP_OP_MISS_NOFETCH for sites which it cannot ping.

 \defgroup IPCacheAPI IP Cache API
 \ingroup Components
 \section Introduction Introduction
 \par
 *  The IP cache is a built-in component of squid providing
 *  Hostname to IP-Number translation functionality and managing
 *  the involved data-structures. Efficiency concerns require
 *  mechanisms that allow non-blocking access to these mappings.
 *  The IP cache usually doesn't block on a request except for
 *  special cases where this is desired (see below).
 *
 \todo IP Cache should have its own API *.h header file.
 */

/**
 \defgroup IPCacheInternal IP Cache Internals
 \ingroup IPCacheAPI
 \todo  when IP cache is provided as a class. These sub-groups will be obsolete
 *  for now they are used to seperate the public and private functions.
 *  with the private ones all being in IPCachInternal and public in IPCacheAPI
 *
 \section InternalOperation Internal Operation
 *
 * Internally, the execution flow is as follows: On a miss,
 * ipcache_getnbhostbyname checks whether a request for
 * this name is already pending, and if positive, it creates
 * a new entry using ipcacheAddNew with the IP_PENDING
 * flag set . Then it calls ipcacheAddPending to add a
 * request to the queue together with data and handler.  Else,
 * ipcache_dnsDispatch() is called to directly create a
 * DNS query or to ipcacheEnqueue() if all no DNS port
 * is free.  ipcache_call_pending() is called regularly
 * to walk down the pending list and call handlers. LRU clean-up
 * is performed through ipcache_purgelru() according to
 * the ipcache_high threshold.

.
.SH DESCRIPTION
.PP
.B squid
is a high\-performance proxy caching server for web clients,
supporting FTP, gopher, ICAP, ICP, HTCP and HTTP data objects.
Unlike traditional caching software, 
Squid handles all requests in a single, non-blocking process.
.PP
Squid keeps meta data and especially hot objects cached in RAM, 
caches DNS lookups, supports non\-blocking DNS lookups, and implements
negative caching of failed requests.
.PP
Squid supports SSL, extensive access controls, and full request logging. 
By using the lightweight Internet Cache Protocols ICP, HTCP or CARP, 
Squid caches can be arranged in a hierarchy or mesh for additional 
bandwidth savings.
.PP
Squid consists of a main server program
.B squid
, some optional programs for 
custom processing and authentication, and some management and client
tools.  When squid starts up, it spawns a configurable number of
helper processes, each of which can perform parallel lookups.
This reduces the amount of time the cache waits for results.
.PP
Squid is derived from the ARPA\-funded Harvest Project.
.PP
This manual page only lists the command line arguments.
For details on how to configure Squid see the file 
.BI @SYSCONFDIR@/squid.conf.documented,
the Squid wiki FAQ and examples at http://wiki.squid-cache.org/ ,
or the configuration manual on the Squid home page
.if !'po4a'hide' http://www.squid-cache.org/Doc/config/
.
.SH OPTIONS
.if !'po4a'hide' .TP 12
.if !'po4a'hide' .B "\-a port"
Specify HTTP port number where Squid should listen for requests, in addition to any
.B http_port
specifications in 
.B squid.conf
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-C
Do not catch fatal signals.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-d level"
Write debugging to stderr also.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-f file"
Use the given config-file instead of
.B @SYSCONFDIR@/squid.conf .
If the file name starts with a 
.B !
or
.B |
then it is assumed to be an external command or command line.
Can for example be used to pre\-process the configuration before it is being read by Squid.
To facilitate this Squid also understands the common #line notion to indicate the real source file.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-F
Don't serve any requests until store is rebuilt.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-h
Print help message.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-i
Install as a Windows Service (see
.B \-n
option).
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-k reconfigure | rotate | shutdown | interrupt | kill | debug | check | parse"
Parse configuration file, then send signal to running copy 
(except
.B "\-k parse"
) and exit.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-l facility"
Use specified syslog facility. Implies
.B \-s
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-n name"
Specify Windows Service name to use for service operations, default is: 
.B Squid
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-N
No daemon mode.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-O options"
Set Windows Service Command line options in Registry.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-r
Remove a Windows Service (see
.B \-n
option).
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-R
Do not set
.B REUSEADDR
on port.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-s
Enable logging to syslog. Also configurable in
.BI @SYSCONFDIR@/squid.conf
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-S
Double-check swap during rebuild.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B "\-u port"
Specify ICP port number (default: 3130), disable with 0.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-v
Print version and build details.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-X
Force full debugging.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-Y
Only return
.B UDP_HIT
or
.B UDP_MISS_NOFETCH
during fast reload.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-z
Create missing swap directories and other missing cache_dir structures,
then exit. All cache_dir types create the configured top-level directory if 
it is missing. Other actions are type-specific. For example, ufs-based
storage systems create missing L1 and L2 directories while Rock creates
the missing database file.
.IP
This option does not enable validation of any present swap structures. Its
focus is on creation of missing pieces. If nothing is missing, squid -z 
just exits. If you suspect cache_dir corruption, you must delete the top-level
cache_dir directory before running squid -z.
.IP
By default, squid -z runs in daemon mode (so that configuration macros and
other SMP features work as expected). Use
.B \-N
option to overwrite this.
.
.SH FILES
Squid configuration files located in @SYSCONFDIR@/:
.
.if !'po4a'hide' .IP "squid.conf"
The main configuration file. You must initially make changes to this file for 
.B squid
to work. For example, the default configuration only allows access from RFC private LAN networks.
Some packaging distributions block even that.
.
.if !'po4a'hide' .IP "squid.conf.default"
Reference copy of the configuration file. Always kept up to date with
the version of Squid you are using.
.IP
Use this to look up the default configuration settings and syntax after upgrading.
.
.if !'po4a'hide' .IP "squid.conf.documented"
Reference copy of the configuration file. Always kept up to date with
the version of Squid you are using.
.IP
Use this to read the documentation for configuration options available in
your build of Squid. The online configuration manual is also available for
a full reference of options.
.BR see http://www.squid-cache.org/Doc/config/
.
.if !'po4a'hide' .IP "cachemgr.conf"
The main configuration file for the web
.B cachemgr.cgi
tools.
.
.if !'po4a'hide' .IP "msntauth.conf"
The main configuration file for the Sample MSNT authenticator.
.
.if !'po4a'hide' .IP "errorpage.css"
CSS Stylesheet to control the display of generated error pages.
Use this to set any company branding you need, it will apply to every
language Squid provides error pages for.
.PP
.br
Some files also located elsewhere:
.
.if !'po4a'hide' .IP "@DEFAULT_MIME_TABLE@ (mime_table)"
MIME type mappings for FTP gatewaying
.
.if !'po4a'hide' .IP "@DEFAULT_ERROR_DIR@"
Location of Squid error pages and templates.

 \par
 * Connects Squid client-side to an SSL peer (cache_peer ... ssl).
 * Handles peer certificate validation.
 * Used by TunnelStateData, FwdState, and PeerPoolMgr to start talking to an
 * SSL peer.
 \par
 * The caller receives a call back with PeerConnectorAnswer. If answer.error
 * is not nil, then there was an error and the SSL connection to the SSL peer
 * was not fully established. The error object is suitable for error response
 * generation.
 \par
 * The caller must monitor the connection for closure because this
 * job will not inform the caller about such events.
 \par
 * PeerConnector class curently supports a form of SSL negotiation timeout,
 * which accounted only when sets the read timeout from SSL peer.
 * For a complete solution, the caller must monitor the overall connection
 * establishment timeout and close the connection on timeouts. This is probably
 * better than having dedicated (or none at all!) timeouts for peer selection,
 * DNS lookup, TCP handshake, SSL handshake, etc. Some steps may have their
 * own timeout, but not all steps should be forced to have theirs.
 * XXX: tunnel.cc and probably other subsystems does not have an "overall
 * connection establishment" timeout. We need to change their code so that they
 * start monitoring earlier and close on timeouts. This change may need to be
 * discussed on squid-dev.
 \par
 * This job never closes the connection, even on errors. If a 3rd-party
 * closes the connection, this job simply quits without informing the caller.

.SH NAME
ssl_crtd \- SSL certificate generator for Squid.
.PP
Version 1.0
.
.SH SYNOPSIS
.if !'po4a'hide' .B ssl_crtd
.if !'po4a'hide' .B [\-dhv]
.
.if !'po4a'hide' .B ssl_crtd
.if !'po4a'hide' .B "[\-d] -s "
directory
.if !'po4a'hide' .B [\-M 
size
.if !'po4a'hide' .B ]
.
.if !'po4a'hide' .B ssl_crtd
.if !'po4a'hide' .B "[\-d] \-c \-s "
directory
.if !'po4a'hide' .B [\-n]
serial number
.
.if !'po4a'hide' .B ssl_crtd
.if !'po4a'hide' .B "[\-d] \-g \-s "
directory
.
.SH DESCRIPTION
.B ssl_crtd
is an installed binary.
.PP
Because the generation and signing of SSL certificates takes time
Squid must use external process to handle the work.
.
This process generates new SSL certificates and uses a disk cache of certificatess
to improve response times on repeated requests.
Communication occurs via TCP sockets bound to the loopback interface.
.
.SH OPTIONS
.if !'po4a'hide' .TP 12
.if !'po4a'hide' .B \-b fs_block_size
File system block size in bytes. Needed for processing natural size of certificate on disk.
Default value is 2048 bytes.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-c
Initialize the SSL storage database and exit.
Requires the 
.B -s 
option to determine the storage location being created.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-d
Write debug info to stderr.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-g
Display the current serial number using stderr and exit.
Requires 
.B \-s 
option to determine which storage directory the serial is located in.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-h
Display the binary help and command line syntax info using stderr.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-s directory
Directory path of disk storage for new SSL certificates.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-M size
Maximum size of SSL certificate disk storage.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-n serial number
HEX 
.B "serial number "
to use when initializing an SSL storage database.
The default value of serial number is the number of seconds since Epoch minus 1200000000.
.
.if !'po4a'hide' .TP
.if !'po4a'hide' .B \-v
Display the binary version details using stderr.
.
.SH KNOWN ISSUES
.PP
.B SSL errors after changing the CA
.
.PP
Certificates are stored in this database in signed form.
After any change to the signing CA in squid.conf be sure to erase and re-initialize the certificate database.
.
.PP
.B Certificate chaining
.
.PP
The version 1.0 of this helper will not add chained intermediate CA certificates.
The client must have a full chain of trust from the root CA all the way
down to the end certificate generated by this program.
.
Signing with an intermediate CA needs to install both the
root and the intermediate public CA on the clients.
.
.SH CONFIGURATION
.PP
Before this helper can be used the storage area for new certificates must be initialized manually.
This is done from the command line using the 
.B \-c 
parameters.
.
.PP
For example:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B ssl_crtd -c -s /var/lib/ssl_db
.if !'po4a'hide' .RE
.
.PP
Certificates are stored in this database in signed form.
After any change to the signing CA in squid.conf be sure to erase and re-initialize the certificate database.
.
.PP
For simple configuration the helper defaults can be used.
Only HTTP listening port options are required to enable generation and set the signign CA certificate.
For Example:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B http_port 3128 ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/usr/local/squid/ssl_cert/www.sample.com.pem
.if !'po4a'hide' .RE
.
.PP
For more customized configuration the helper certificate storage directory location and size can be altered with the
.B sslcrtd_program 
configuration directive.
For example:
.if !'po4a'hide' .RS
.if !'po4a'hide' .B sslcrtd_program /usr/local/squid/libexec/ssl_crtd -s /usr/local/squid/var/lib/ssl_db -M 4MB
.if !'po4a'hide' .
.if !'po4a'hide' .B sslcrtd_children 5
.if !'po4a'hide' .RE
.

    Because the standart generation of ssl certificate for
    sslBump feature, Squid must use external proccess to
    actually make these calls. This process generate new ssl
    certificates and worked with ssl certificates disk cache.
    Typically there will be five ssl_crtd processes spawned
    from Squid. Communication occurs via TCP sockets bound
    to the loopback interface. The class in helper.h are
    primally concerned with starting and stopping the ssl_crtd.
    Reading and writing to and from the ssl_crtd occurs in the
    \link IPCacheAPI IP\endlink and the dnsservers occurs in
    the \link IPCacheAPI IP\endlink and \link FQDNCacheAPI
    FQDN\endlink cache modules.

It does so by acting as a middleman between squid and the actual helpers, talking to squid via the multiplexed variant of the helper protocol and to the helpers via the non-multiplexed variant. Helpers are started on demand, and in theory the muxer can handle up to 1k helpers per instance. It's up to squid to decide how many helpers to start. The muxer knows nothing about the actual messages being passed around, and as such can't really (yet?) compensate for broken helpers. It is not yet able to manage dying helpers, but it will. The helper can be controlled using various signals: - SIGHUP: dump the state of all helpers to STDERR squid3-3.5.12/tools/helper-mux.pl000077500000000000000000000124211262763202500166050ustar00rootroot00000000000000#!/usr/bin/perl # ## Copyright (C) 1996-2015 The Squid Software Foundation and contributors ## ## Squid software is distributed under GPLv2+ license and includes ## contributions from numerous individuals and organizations. ## Please see the COPYING and CONTRIBUTORS files for details. ## # # helper multiplexer.

You can use purge to have a look at what URLs are stored in which file within your cache. The purge tool can also be used to release objects which URLs match user specified regular expressions. A more troublesome feature is the ability to remove files squid does not seem to know about any longer. USE AT YOUR OWN RISK! NO GUARANTEES, WHATSOEVER! DON'T BLAME US! YOU HAVE BEEN WARNED! compilation =========== Purge has been successfully compiled under the following OSes: SYSTEM g++ native ------ --- ------ Solaris 2.7 yes CC IRIX 6.5 yes CC -n32 Linux 2.0.36 yes (g++ IS native) FreeBSD 4.x yes gmake port must be installed (g++ IS supported) The recent move of the Linux community towards glibc2 may cause some troubles, though. The compilation requires GNU make, no other make will work correctly. The source distribution contains all files checked into the revision control repository. Therefore, you will need to install GNU RCS first (which in turn needs the GNU diffutils). The repository also contains the prototypical Perl implementation. The user interface in the C++ implementation changed a little when compared to the Perl one. You will have to state at least one regular expression for purge to start working. Also, printing the complete cache URLs, you will need to specify the "-e ." regular expression. In order to compile the purge tool, untar the source distribution and change into the purge directory. With RCS and GNU make installed, just say "make". GNU make will automagically retrieve all necessary files from the repository and create the binary. Systems not stated above will need to retrieve the makefile (use "co -l Makefile" for this) and add their own platform specific definitions to section [2] in the makefile. squid preparation ================= In order to use purge for real PURGEs, you will have to enable this feature in squid. By default, PURGE is disabled. You should watch closely for whom you enable the PURGE ability, otherwise total stranger just might wipe your cache content. The following lines will need to be added to your squid.conf (you may want to add further networks to the src_local ACL): acl purge method PURGE acl src_local src 127.0.0.0/8 http_access allow purge src_local http_access deny purge Reconfigure or restart (preferred) your squid after changing the configuration file. modes of operation ================== Usage: purge [-a] [-c cf] [-d l] [-(f|F) fn | -(e|E) re] [-p h[:p]] [-P #] [-s] [-v] [-C dir [-H]] [-n] -a display a little rotating thingy to indicate that I am alive (tty only). -c c squid.conf location, default "/usr/local/squid/etc/squid.conf". -C dir base directory for content extraction (copy-out mode). -d l debug level, an OR of different debug options. -e re single regular expression per -e instance (use quotes!). -E re single case sensitive regular expression like -e. -f fn name of textfile containing one regular expression per line. -F fn name of textfile like -f containing case sensitive REs. -H prepend HTTP reply header to destination files in copy-out mode. -n do not fork() when using more than one cache_dir. -p h:p cache runs on host h and optional port p, default is localhost:3128. -P # if 0, just print matches; otherwise OR the following purge modes: 0x01 really send PURGE to the cache. 0x02 remove all caches files reported as 404 (not found). 0x04 remove all weird (inaccessible or too small) cache files. 0 and 1 are recommended - slow rebuild your cache with other modes. -s show all options after option parsing, but before really starting. -v show more information about the file, e.g. MD5, timestamps and flags. --- &< snip, snip --- -a is a kind of "i am alive" flag. It can only be activated, if your stdout is a tty. If active, it will display a little rotating line to indicate that there is actually something happening. You should not use this switch, if you capture your stdout in a file, or if your expression list produces many matches. The -a flag is also incompatible with the (default) multi cache_dir mode. default: off See also: -n -c cd CHANGED! this option lets you specify the location of the squid.conf file. Purge now understands about more than one cache_dir, and does so by parsing Squid's configuration file. It knows about both ways of Squid-2 cache_dir specifications, and will automatically try to use the correct one. default: /usr/local/squid/etc/squid.conf -C cd if you want to rescue files from your cache, you need to specify the directory into which the files will be copied. Please note that purge will try to establish the original server's directory structure. This switch also activates copy-out mode. Please do not use copy-out mode with any purge mode (-P) other than 0. For instance, if you specified "-C /tmp", Purge will try to recreate /tmp/www.server.1/url/path/file, and so forth. default: off See also: -H, -P -d l lets you specify a debug level. Differents bits are reserved for different output. default: 0 -e re the "-e" options let you specify one regular expression at the -E re commandline. This is useful, if there is only a handful you want to check. Please remember to escape the shell metachars used in your regular expression. The use of single quotes around your expression is recommended. The capital letter version works case sensitive, the lower caps version does not. default: (no default) -f fn if you have more than a handful of expression, or want to check -F fn the same set at regular intervals, the file option might be more useful to you. Each line in the text file will be regarded as one regular expression. Again, the capital letter version works case sensitive, the lower caps version does not. default: (no default) -H if in copy-out mode (see: -C), you can specify to keep the HTTP Header in the recreated file. default: off See also: -C -n by specifying the "-n" switch, you will tell Purge to process one cache_dir after another, instead of doing things in parallel. If you have more than one cache_dir in your configuration, Purge will fork off a worker process for each cache_dir to do the checks for optimum speed - assuming a decently designed cache. Since parallel execution will put quite some load on the system and its controllers, it is sometimes preferred to use less resources, though it will take longer. default: parallel mode for more than one cache_dir -p h[:p] Some cache admins (i.e. me) use a different port than 3128. The purge tool will need to connect to your cache in order to send the PURGE request (see -P). This option lets you specify the host and port to connect to. The port is optional. The port can be a name (check your /etc/services) or number. It is separated from the host name portion by a single colon, no spaces allowed. default: localhost:3128 -P # If you want to do more than just print your cache content, you will need to specify this option. Each bit is reserved for a different action. Only the use of the LSB is recommended, the rest should be considered experimental. no bit set: just print bit#0 set: send PURGE for matches bit#1 set: unlink object file for 404 not found PURGEs bit#2 set: unlink weird object files If you use a value other than 0 or 1, you will need to slow rebuild your cache content. A warning message will remind you of that. If you use bit#1, all unsuccessful PURGEs will result in the object file in your cache directory to be removed, because squid does not seem to know about it any longer. Beware that the asyncio might try to remove it after the purge tool, and thus complains bitterly. Bit#1 only makes sense, if Bit#0 is also set, otherwise it has no effect (since the HTTP status 404 is never returned). Bit#2 is reserved for strange files which do not even contain a URL. Beware that these files may indicate a new object squid currently intends to swap onto disk. If the file suddenly went away, or is removed when squid tries to fetch the object, it will complain bitterly. You must slow rebuild your cache, if you use this option. It is recommended that if you dare to use bit#1 or bit#2, you should only grant the purge tool access to your squid, e.g. move the HTTP and ICP listening port of squid to a different non-standard location during the purge. default: 0 (just print) -s If you specify this switch, all commandline parameters will be shown after they were parsed. default: off -v be verbose in the things reported about the file. See the output section below. output ====== In regular mode, the output of purge consists of four columns. If the URL contains not encoded whitespaces, it may look as if there are more columns, but the last one is the URI. # name meaning - ------ ----------------------------------------------------------- 1 file name of cache file eximed which matches the re. 2 status return result of purge request, " 0" in print mode. 3 size object size including stored headers, not file size. 4 uri perceived uri Example for non-verbose output in print-mode: /cache3/00/00/0000004A 0 5682 http://graphics.userfriendly.org/images/slovenia.gif In verbose mode, additional columns are inserted before the uri. Time stamps are reported using hexadecimal notation, and Squid's standard for reporting "no such timestamp" == -1, and "unparsable timestamp" == -2. # name meaning - ------ ----------------------------------------------------------- 1 file name of cache file eximed which matches the re. 2 status return result of purge request, " 0" in print mode "-P 0". 3 size object size including stored headers, not file size. 4 md5 MD5 of URI from file, or "(no_md5_data_available)" string. 5 ts UTC of Value of Date: header in hex notation 6 lr UTC of last time the object was referenced 7 ex UTC of Expires: header 8 lr UTC of Last-Modified: header 9 flags Value of objects flags field in hex, see: Programmers Guide 10 refcnt number of times the object was referenced. 11 uri STORE_META_URL uri or "strange_file" Example for verbose output in print-mode: /cache1/00/00/000000B7 0 406 7CFCB1D319F158ADC9CFD991BB8F6DCE 397d449b 39bf677b ffffffff 3820abfc 0460 1 http://www.netscape.com/images/nc_vera_tile.gif limitations =========== o Purge does not slow rebuild the cache for you. o It is still relatively slow, especially if your machine is low on memory and/or unable to hold all OS directory cache entries in main memory. o should never be used on "busy" caches with purge modes higher than 1. TODO ==== 1) use the stat() result on weird files to have a look at their ctime and mtime. If they are younger than, lets say 30 seconds, they were just created by squid and should not be removed. 2) Add a query before purging objects or removing files, and add another option to remove nagging for the experienced user. 3) The reported object size may be off by one. squid3-3.5.12/tools/purge/conffile.cc000066400000000000000000000166531262763202500174100ustar00rootroot00000000000000/* * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. */ // Author: Jens-S.

Designed for testing any HTTP 0.9, 1.0, or 1.1 web server or proxy. This tool can be combined with scripts to perform any basic HTTP operation. Some additional features for access to the .B squid proxy object cache and management information are provided. . .SH OPTIONS .if !'po4a'hide' .TP 12 .if !'po4a'hide' .B "\-a" Do NOT include Accept: header. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-A 'string'" Send .B string as User-Agent: header. To omit the header completely set string to empty (''). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-h | \-\-host host" Retrieve URL from server host. Default is .B localhost . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-H 'string'" Extra headers to send. Use .B '\\n' for new lines. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-i time" If\-Modified\-Since time (in Epoch seconds). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-j hosthdr" Host header content . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-k" Keep the connection active. Default is to do only one request then close. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-l | \-\-local host" Specify a local IP address to bind to. Default is none. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-m method" Request method, default is .I GET. Squid also supports a non-standard method called .I PURGE. You can use that to purge a specific URL from the cache. You need to have .I purge access setup in .B squid.conf similar to .I manager access. Here is an example: .if !'po4a'hide' .nf .if !'po4a'hide' acl purge method PURGE .if !'po4a'hide' http_access deny purge !localhost .if !'po4a'hide' .fi . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-n" Proxy Negotiate(Kerberos) authentication. .if !'po4a'hide' .nf Use kinit username@DOMAIN first to get initial TGS. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-N" WWW Negotiate(Kerberos) authentication. .if !'po4a'hide' .nf Use kinit username@DOMAIN first to get initial TGS. .if !'po4a'hide' .fi . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-p port" Port number of cache. Default is 3128. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-P file" Request body. Using the named file as data. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-r" Force cache to reload URL. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-s" Silent. Do not print data to stdout. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-t count" Trace .I count HTTP relay or proxy hops . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-T timeout" Timeout value (seconds) for read/write operations. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-u user" Proxy authentication username . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-U user" WWW authentication username . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-v" Verbose. Print outgoing message to stderr. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-V version" HTTP Version. Use '\-' for HTTP/0.9 omitted case . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-w password" Proxy authentication password . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-W password" WWW authentication password . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-https" Use Transport Layer Security on the HTTP connection. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-anonymous\-tls" Use TLS with unauthenticated (anonymous) certificate. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-cert file" File containing client X.509 certificate in PEM format. May be repeated to load several client certificates. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-trusted\-ca file" File containing trusted Certificate Authority (CA) certificates in PEM format. May be repeated to load any number of files. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-params values" TLS library specific parameters for the communication session. See the library documentation for details on valid parameters. .if !'po4a'hide' .I "GnuTLS: http://gnutls.org/manual/html_node/Priority\-Strings.html" If repeated only the last value will have effect. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-\-ping [options]" Enable ping mode. Optional \-g and \-I parameters must follow immediately if used. Repeated use resets to default ping settings. . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-g count" Ping mode, perform\ .I count iterations (default is to loop until interrupted). . .if !'po4a'hide' .TP .if !'po4a'hide' .B "\-I interval" Ping interval in seconds (default 1 second). . .SH AUTHOR This program and manual was written by .if !'po4a'hide' .I Amos Jeffries .PP Based on original code derived from Harvest and further developed by numerous individuals from the internet community. . .SH COPYRIGHT .PP * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. . .SH QUESTIONS Questions on the usage of this program can be sent to the .I Squid Users mailing list .if !'po4a'hide' . .SH REPORTING BUGS See http://wiki.squid-cache.org/SquidFaq/BugReporting for details of what you need to include with your bug report. .PP Report bugs or bug fixes using http://bugs.squid-cache.org/ .PP Report serious security bugs to .I Squid Bugs .PP Report ideas for new improvements to the .I Squid Developers mailing list .if !'po4a'hide' . .SH SEE ALSO .if !'po4a'hide' .BR squid "(8), " .if !'po4a'hide' .BR cachemgr.cgi "(8)" squid3-3.5.12/tools/squidclient/squidclient.cc000066400000000000000000000416421262763202500213450ustar00rootroot00000000000000/* * Copyright (C) 1996-2015 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details. */ #include "squid.h" #include "base64.h" #include "ip/Address.h" #include "ip/tools.h" #include "rfc1123.h" #include "tools/squidclient/gssapi_support.h" #include "tools/squidclient/Parameters.h" #include "tools/squidclient/Ping.h" #include "tools/squidclient/Transport.h" #if _SQUID_WINDOWS_ /** \cond AUTODOCS-IGNORE */ using namespace Squid; /** \endcond */ #endif #include #include #include #include #if _SQUID_WINDOWS_ #include #endif #if HAVE_SYS_SOCKET_H #include #endif #if HAVE_UNISTD_H #include #endif #if HAVE_NETDB_H #include #endif #if HAVE_SYS_STAT_H #include #endif #if HAVE_FCNTL_H #include #endif #if HAVE_NETINET_IN_H #include #endif #if HAVE_GETOPT_H #include #endif #ifndef BUFSIZ #define BUFSIZ 8192 #endif #ifndef MESSAGELEN #define MESSAGELEN 65536 #endif #ifndef HEADERLEN #define HEADERLEN 65536 #endif /* Local functions */ static void usage(const char *progname); void pipe_handler(int sig); static void set_our_signal(void); Parameters scParams; static int put_fd; static char *put_file = NULL; static struct stat sb; int total_bytes = 0; #if _SQUID_AIX_ /* Bug 3854: AIX 6.1 tries to link in this fde.h global symbol * despite squidclient not using any of the fd_* code. */ fde *fde::Table = NULL; #endif #if _SQUID_WINDOWS_ void Win32SockCleanup(void) { WSACleanup(); return; } #endif static void usage(const char *progname) { std::cerr << "Version: " << VERSION << std::endl << "Usage: " << progname << " [Basic Options] [HTTP Options]" << std::endl << std::endl; std::cerr << " -s | --quiet Silent.
