The first and primary application for GNUnet is anonymous file-sharing. GNUnet is currently developed by a worldwide group of independent free software developers. GNUnet is a GNU package (http://www.gnu.org/). This is an ALPHA release. There are known and significant bugs as well as many missing features in this release. Additional documentation about GNUnet can be found at https://gnunet.org/. Dependencies: ============= Please note that for many of its dependencies GNUnet requires very recent versions of the libraries which are often NOT to be found in stable distributions in 2011. While using older packages may in some cases on some operating systems may seem to work in some limited fashion, we are in many cases aware of serious problems with older packages. Hence please make sure to use the versions listed below. These are the direct dependencies for running GNUnet: - libextractor >= 0.6.1 - libmicrohttpd >= 0.9.33 - libgcrypt >= 1.6 - libgnurl >= 7.35.0 (available from https://gnunet.org/gnurl) - libunistring >= 0.9.2 - gnutls >= 3.2.12 - libidn >= 1.0 - libglpk >= 4.45 - openssl >= 1.0 (binary, used to generate X.509 certificate) - libltdl >= 2.2 (part of GNU libtool) - sqlite >= 3.8 (default database, required) - mysql >= 5.1 (alternative to sqlite) - postgres >= 8.3 (alternative to sqlite) - libopus >= 1.0.1 (optional for experimental conversation tool) - libpulse >= 2.0 (optional for experimental conversation tool) - libogg >= 1.3.0 (optional for experimental conversation tool) - python-zbar >= 0.10 (optional for gnunet-qr) - TeX Live >= 2012 (optional for gnunet-bcd) Recommended autotools for compiling the SVN version are: - autoconf >= 2.59 - automake >= 1.11.1 - libtool >= 2.2 How to install? =============== The fastest way is to use a binary package if it is available for your system. For a more detailed description, read the installation instructions on the webpage at https://gnunet.org/installation. Note that some functions of GNUnet require "root" access. GNUnet will install (tiny) SUID binaries for those functions is you run "make install" as root. If you do not, GNUnet will still work, but some functionality will not be available (including certain forms of NAT traversal). GNUnet requires the GNU MP library (http://www.gnu.org/software/gmp/) and libgcrypt (http://www.gnupg.org/). You can specify the path to libgcrypt by passing "--with-gcrypt=PATH" to configure. You will also need either sqlite (http://www.sqlite.org/), MySQL (http://www.mysql.org/) or PostGres (http://www.postgres.org/). If you install from source, you need to install GNU libextractor first (download from http://www.gnu.org/software/libextractor/). We also recommend installing GNU libmicrohttpd (download from http://www.gnu.org/software/libmicrohttpd/). Then you can start the actual GNUnet compilation and installation process with: $ export GNUNET_PREFIX=/usr/local # or other directory of your choice # addgroup gnunetdns # adduser gnunet gnunet # ./configure --prefix=$GNUNET_PREFIX --with-extractor=$LE_PREFIX $ make # make install # sudo -u gnunet gnunet-arm -s Note that running the 'configure' and 'make install' steps as root (or with sudo) is required as some parts of the installation require the creation of SUID binaries. The installation will work if you do not run these steps as root, but some components may not be installed in the perfect place or with the right permissions and thus won't work. This will create the users and groups needed for running GNUnet securely and then compile and install GNUnet to $GNUNET_PREFIX/bin/, $GNUNET_PREFIX/lib/ and $GNUNET_PREFIX/share/ and start the system with the default configuration. It is strongly recommended that you add a user "gnunet" to run "gnunet-arm". You can then still run the end-user applications as another user. If you create a system user "gnunet", it is recommended that you edit the configuration file slightly so that data can be stored in the system user home directory at "/var/lib/gnunet". Depending on what the $HOME-directory of your "gnunet" user is, you might need to set the SERVICEHOME option in section "[PATHS]" to "/var/lib/gnunet" to do this. Depending on your personal preferences, you may also want to use "/etc/gnunet.conf" for the location of the configuration file in this case (instead of ~gnunet/.config/gnunet.conf"). In this case, you need to start GNUnet using "gnunet-arm -s -c /etc/gnunet.conf" or set "XDG_CONFIG_HOME=/etc/". You can avoid running 'make install' as root if you run configure with the "--with-sudo=yes" option and have extensive sudo rights (can run "chmod +s" and "chown" via 'sudo'). If you run 'make install' as a normal user without sudo rights (or the configure option), certain binaries that require additional priviledges will not be installed properly (and autonomous NAT traversal, WLAN, DNS/GNS and the VPN will then not work). If you run 'configure' and 'make install' as root or use the SUDO option, GNUnet's build system will install "libnss_gns*" libraries to "/lib/" regardless (!) of the $GNUNET_PREFIX you might have specified, as those libraries must be in "/lib/". If you are packaging GNUnet for binary distribution, this may cause your packaging script to miss those plugins, so you might need to do some additional manual work to include those libraries in your binary package(s). Similarly, if you want to use the GNUnet naming system and did NOT run GNUnet's 'make install' process with SUDO rights, the libraries will be installed to "$GNUNET_PREFIX/lib" and you will have to move them to "/lib/" manually. Finally, if you are compiling the code from subversion, you have to run ". bootstrap" before ./configure. If you receive an error during the running of ". bootstrap" that looks like "macro `AM_PATH_GTK' not found in library", you may need to run aclocal by hand with the -I option, pointing to your aclocal m4 macros, i.e. $ aclocal -I /usr/local/share/aclocal Configuration ============= Note that additional, per-user configuration files can be created by each user. However, this is usually not necessary as there are few per-user options that normal users would want to modify. The defaults that are shipped with the installation are usually just fine. The gnunet-setup tool is particularly useful to generate the master configuration for the peer. gnunet-setup can be used to configure and test (!) the network settings, choose which applications should be run and configure databases. Other options you might want to control include system limitations (such as disk space consumption, bandwidth, etc.). The resulting configuration files are human-readable and can theoretically be created or edited by hand. gnunet-setup is a separate download and requires somewhat recent versions of GTK+ and Glade. You can also create the configuration file by hand, but this is not recommended. For more general information about the GNU build process read the INSTALL file. GNUnet uses two types of configuration files, one that specifies the system-wide defaults (typically located in $GNUNET_PREFIX/share/gnunet/config.d/) and a second one that overrides default values with user-specific preferences. The user-specific configuration file should be located in "~/.config/gnunet.conf" or its location can be specified by giving the "-c" option to the respective GNUnet application. Usage ===== First, you must obtain an initial list of GNUnet hosts. Knowing a single peer is sufficient since after that GNUnet propagates information about other peers. Note that the default configuration contains URLs from where GNUnet downloads an initial hostlist whenever it is started. If you want to create an alternative URL for others to use, the file can be generated on any machine running GNUnet by periodically executing $ cat $SERVICEHOME/data/hosts/* > the_file and offering 'the_file' via your web server. Alternatively, you can run the build-in web server by adding '-p' to the OPTIONS value in the "hostlist" section of gnunet.conf and opening the respective HTTPPORT to the public. If the solution with the hostlist URL is not feasible for your situation, you can also add hosts manually. Simply copy the hostkeys to "$SERVICEHOME/data/hosts/" (where $SERVICEHOME is the directory specified in the gnunet.conf configuration file). You can also use "gnunet-peerinfo -g" to GET a URI for a peer and "gnunet-peerinfo -p URI" to add a URI from another peer. Finally, GNUnet peers that use UDP or WLAN will discover each other automatically (if they are in the vicinity of each other) using broadcasts (IPv4/WLAN) or multicasts (IPv6). The local node is started using "gnunet-arm -s". GNUnet should run 24/7 if you want to maximize your anonymity, as this makes partitioning attacks harder. Once your peer is running, you should then be able to access GNUnet using the shell: $ gnunet-search KEYWORD This will display a list of results to the console. You can abort the command using "CTRL-C". Then use $ gnunet-download -o FILENAME GNUNET_URI to retrieve a file. The GNUNET_URI is printed by gnunet-search together with a description. To publish files on GNUnet, use the "gnunet-publish" command. The GTK user interface is shipped separately. After downloading and installing gnunet-gtk, you can invoke the setup tool and the file-sharing GUI with: $ gnunet-setup $ gnunet-fs-gtk For further documentation, see our webpage. Hacking GNUnet ============== Contributions are welcome, please submit bugs to https://gnunet.org/bugs/. Please make sure to run contrib/report.sh and include the output with your bug reports. More about how to report bugs can be found in the GNUnet FAQ on the webpage. Submit patches via E-Mail to gnunet-developers@gnu.org. In order to run the unit tests with "make check", you need to set an environment variable ("GNUNET_PREFIX") to the directory where GNUnet is installed (usually, GNUnet will use OS specific tricks in order to try to figure out the PREFIX, but since the testcase binaries are not installed, that trick does not work for them). Also, before running any testcases, you must complete the installation first. Quick summary: $ ./configure --prefix=$SOMEWHERE $ make $ make install $ export GNUNET_PREFIX=$SOMEWHERE $ make check Some of the testcases require python >= 2.6 and pexpect to be installed. If any testcases fail to pass on your system, run "contrib/report.sh" and report the output together with information about the failing testcase to the Mantis bugtracking system at https://gnunet.org/bugs/. Running HTTP on port 80 and HTTPS on port 443 ============================================= In order to hide GNUnet's HTTP/HTTPS traffic perfectly, you might consider running GNUnet's HTTP/HTTPS transport on port 80/443. However, we do not recommend running GNUnet as root. Instead, forward port 80 to say 1080 with this command (as root, in your startup scripts): # iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 1080 or for HTTPS # iptables -t nat -A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 4433 Then set in the HTTP section of gnunet.conf the "ADVERTISED_PORT" to "80" and "PORT" to 1080 and similarly in the HTTPS section the "ADVERTISED_PORT" to "443" and "PORT" to 4433. You can do the same trick for the TCP and UDP transports if you want to map them to a priviledged port (from the point of view of the network). However, we are not aware of this providing any advantages at this point. If you are already running an HTTP or HTTPS server on port 80 (or 443), you may be able to configure it as a "ReverseProxy". Here, you tell GNUnet that the externally visible URI is some sub-page on your website, and GNUnet can then tunnel its traffic via your existing HTTP server. This is particularly powerful if your existing server uses HTTPS, as it makes it harder for an adversary to distinguish normal traffic to your server from GNUnet traffic. Finally, even if you just use HTTP, you might benefit (!) from ISP's traffic shaping as opposed to being throttled by ISPs that dislike P2P. Details for configuring the reverse proxy are documented on our website.

These substitutes look strange; see # http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html # # This catalog translates grave accent (0x60) and apostrophe (0x27) to # left single quotation mark (U+2018) and right single quotation mark (U+2019). # It also translates pairs of apostrophe (0x27) to # left single quotation mark (U+2018) and right single quotation mark (U+2019) # and pairs of quotation mark (0x22) to # left double quotation mark (U+201C) and right double quotation mark (U+201D). # # When output to an UTF-8 terminal, the quotation characters appear perfectly. # When output to an ISO-8859-1 terminal, the single quotation marks are # transliterated to apostrophes (by iconv in glibc 2.2 or newer) or to # grave/acute accent (by libiconv), and the double quotation marks are # transliterated to 0x22. # When output to an ASCII terminal, the single quotation marks are # transliterated to apostrophes, and the double quotation marks are # transliterated to 0x22. # # This catalog furthermore displays the text between the quotation marks in # bold face, assuming the VT100/XTerm escape sequences. # gnunet-0.10.1/po/Makefile.in.in0000644000175000017500000003322112221077151013101 00000000000000# Makefile for PO directory in any package using GNU gettext. # Copyright (C) 1995-1997, 2000-2006 by Ulrich Drepper # # This file can be copied and used freely without restrictions.

The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that free software will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work on translations can contact the appropriate team. When reporting bugs in the `intl/' directory or bugs which may be related to internationalization, you should tell about the version of `gettext' which is used. The information can be found in the `intl/VERSION' file, in internationalized packages. 1.1 Quick configuration advice ============================== If you want to exploit the full power of internationalization, you should configure it using ./configure --with-included-gettext to force usage of internationalizing routines provided within this package, despite the existence of internationalizing capabilities in the operating system where this package is being installed. So far, only the `gettext' implementation in the GNU C library version 2 provides as many features (such as locale alias, message inheritance, automatic charset conversion or plural form handling) as the implementation here. It is also not possible to offer this additional functionality on top of a `catgets' implementation. Future versions of GNU `gettext' will very likely convey even more functionality. So it might be a good idea to change to GNU `gettext' as soon as possible. So you need _not_ provide this option if you are using GNU libc 2 or you have installed a recent copy of the GNU gettext package with the included `libintl'. 1.2 INSTALL Matters =================== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. If not, the included GNU `gettext' library will be used. This library is wholly contained within this package, usually in the `intl/' subdirectory, so prior installation of the GNU `gettext' package is _not_ required. Installers may use special options at configuration time for changing the default behaviour. The commands: ./configure --with-included-gettext ./configure --disable-nls will, respectively, bypass any pre-existing `gettext' to use the internationalizing routines provided within this package, or else, _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl.a' file and will decide to use this. This might not be desirable. You should use the more recent version of the GNU `gettext' library. I.e. if the file `intl/VERSION' shows that the library which comes with this package is more recent, you should use ./configure --with-included-gettext to prevent auto-detection. The configuration process will not test for the `catgets' function and therefore it will not be used. The reason is that even an emulation of `gettext' on top of `catgets' could not provide all the extensions of the GNU `gettext' library. Internationalized packages usually have many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. 1.3 Using This Package ====================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of `LL_CC', with `LL' denoting the language and `CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as `LL' or `LL_CC.ENCODING'. You can get the list of locales supported by your system for your language by running the command `locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. Special advice for Norwegian users: The language code for Norwegian bokma*l changed from `no' to `nb' recently (in 2003). During the transition period, while some message catalogs for this language are installed under `nb' and some older ones under `no', it's recommended for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and older translations are used. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. 1.4 Translating Teams ===================== For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `translation@iro.umontreal.ca' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skills are praised more than programming skills, here. 1.5 Available Packages ====================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of October 2006. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If October 2006 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'. 1.6 Using `gettext' in new packages =================================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle the use of `gettext' the only thing missing are the translations.

Since * it uses RAW sockets, it must be installed SUID or run as 'root'. * In order to keep the security risk of the resulting SUID binary * minimal, the program ONLY opens the two RAW sockets with root * privileges, then drops them and only then starts to process * command line arguments. The code also does not link against * any shared libraries (except libc) and is strictly minimal * (except for checking for errors).

Channels are identified * and accessed in this API using a public/private key. * Higher-level applications should use NAMES within GNS * to obtain public keys, and the distinction between * 'places' and 'persons' can then be made with the help * of the naming system (and/or conventions). * Channels are (as in PSYC) organized into a hierarchy; each * channel master (the one with the private key) is then * the operator of the multicast group (its Origin in * the terminology of the multicast API). * - The API supports passing large amounts of data using * 'streaming' for the argument passed to a method. State * and variables must fit into memory and cannot be streamed * (thus, no passing of 4 GB of data in a variable; * once we implement this, we might want to create a * @c \#define for the maximum size of a variable). * - PSYC defines standard variables, methods, etc. This * library deliberately abstracts over all of these; a * higher-level API should combine the naming system (GNS) * and standard methods (message, join, part, warn, * fail, error) and variables (action, color, time, * tag, etc.). However, this API does take over the * routing variables, specifically 'context' (channel), * and 'source'. We only kind-of support 'target', as * the target is either everyone in the group or the * origin, and never just a single member of the group; * for such individual messages, an application needs to * construct an 'inbox' channel where the master (only) * receives messages (but never forwards; private responses * would be transmitted by joining the senders 'inbox' * channel -- or a inbox#bob subchannel). The * goal for all of this is to keep the abstractions in this * API minimal: interaction with multicast, try \& slice, * state/variable/channel management. Higher-level * operations belong elsewhere (so maybe this API should * be called 'PSYC-low', whereas a higher-level API * implementing defaults for standard methods and * variables might be called 'PSYC-std' or 'PSYC-high'. */ #ifndef GNUNET_PSYC_SERVICE_H #define GNUNET_PSYC_SERVICE_H #ifdef __cplusplus extern "C" { #if 0 /* keep Emacsens' auto-indent happy */ } #endif #endif #include "gnunet_util_lib.h" #include "gnunet_env_lib.h" #include "gnunet_multicast_service.h" /** * Version number of GNUnet-PSYC API. */ #define GNUNET_PSYC_VERSION 0x00000000 /** * Policy flags for a channel. */ enum GNUNET_PSYC_ChannelFlags { /** * Admission must be confirmed by the master. */ GNUNET_PSYC_CHANNEL_ADMISSION_CONTROL = 1 << 0, /** * Past messages are only available to slaves who were admitted at the time * they were sent to the channel. */ GNUNET_PSYC_CHANNEL_RESTRICTED_HISTORY = 1 << 1 }; /** * PSYC channel policies. */ enum GNUNET_PSYC_Policy { /** * Anyone can join the channel, without announcing his presence; * all messages are always public and can be distributed freely. * Joins may be announced, but this is not required. */ GNUNET_PSYC_CHANNEL_ANONYMOUS = 0, /** * The master must approve membership to the channel, messages must only be * distributed to current channel slaves.

Initially, we are #GNUNET_TRANSPORT_PS_NOT_CONNECTED. * * Then, there are two main paths. If we receive a CONNECT message, we give * the inbound address to ATS. After the check we ask ATS for a suggestion * (#GNUNET_TRANSPORT_PS_CONNECT_RECV_ATS). If ATS makes a suggestion, we * send our CONNECT_ACK and go to #GNUNET_TRANSPORT_PS_CONNECT_RECV_ACK. * If we receive a SESSION_ACK, we go to #GNUNET_TRANSPORT_PS_CONNECTED * (and notify everyone about the new connection). If the operation times out, * we go to #GNUNET_TRANSPORT_PS_DISCONNECT. * * The other case is where we transmit a CONNECT message first. We * start with #GNUNET_TRANSPORT_PS_INIT_ATS. If we get an address, we send * the CONNECT message and go to state #GNUNET_TRANSPORT_PS_CONNECT_SENT. * Once we receive a CONNECT_ACK, we go to #GNUNET_TRANSPORT_PS_CONNECTED * (and notify everyone about the new connection and send * back a SESSION_ACK). If the operation times out, we go to * #GNUNET_TRANSPORT_PS_DISCONNECT. * * If the session is in trouble (i.e. transport-level disconnect or * timeout), we go to #GNUNET_TRANSPORT_PS_RECONNECT_ATS where we ask ATS for a new * address (we don't notify anyone about the disconnect yet). Once we * have a new address, we enter #GNUNET_TRANSPORT_PS_RECONNECT_SENT and send a * CONNECT message. If we receive a * CONNECT_ACK, we go to #GNUNET_TRANSPORT_PS_CONNECTED and nobody noticed that we had * trouble; we also send a SESSION_ACK at this time just in case. If * the operation times out, we go to #GNUNET_TRANSPORT_PS_DISCONNECT (and notify everyone * about the lost connection). * * If ATS decides to switch addresses while we have a normal * connection, we go to #GNUNET_TRANSPORT_PS_CONNECTED_SWITCHING_CONNECT_SENT * and send a SESSION_CONNECT. If we get a SESSION_ACK back, we switch the * primary connection to the suggested alternative from ATS, go back * to #GNUNET_TRANSPORT_PS_CONNECTED and send a SESSION_ACK to the other peer just to be * sure. If the operation times out * we go to #GNUNET_TRANSPORT_PS_CONNECTED (and notify ATS that the given alternative * address is "invalid"). * * Once a session is in #GNUNET_TRANSPORT_PS_DISCONNECT, it is cleaned up and then goes * to (#GNUNET_TRANSPORT_PS_DISCONNECT_FINISHED). If we receive an explicit disconnect * request, we can go from any state to #GNUNET_TRANSPORT_PS_DISCONNECT, possibly after * generating disconnect notifications. * * Note that it is quite possible that while we are in any of these * states, we could receive a 'CONNECT' request from the other peer. * We then enter a 'weird' state where we pursue our own primary state * machine (as described above), but with the 'send_connect_ack' flag * set to 1. If our state machine allows us to send a 'CONNECT_ACK' * (because we have an acceptable address), we send the 'CONNECT_ACK' * and set the 'send_connect_ack' to 2.

If yes, address the disk, otherwise return 'not found'. * * A property of the bloom filter is that sometimes we will have * a match even if the element is not on the disk (then we do * an unnecessary disk access), but what's most important is that * we never get a single "false negative". * * To be able to delete entries from the bloom filter, we maintain * a 4 bit counter in the file on the drive (we still use only one * bit in memory). * * @author Igor Wronsky * @author Christian Grothoff */ #include "platform.h" #include "gnunet_util_lib.h" #define LOG(kind,...)

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `GNoptind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns -1. Then `GNoptind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `GNopterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `GNoptarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `GNoptarg', otherwise `GNoptarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we GNUNET_CRYPTO_random_permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct GNoption' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call. If LONG_ONLY is nonzero, '-' as well as '--' can introduce long-named options. */ static int GN_getopt_internal (int argc, char *const *argv, const char *optstring, const struct GNoption *longopts, int *longind, int long_only) { static int __getopt_initialized = 0; static int GNopterr = 1; GNoptarg = NULL; if (GNoptind == 0 || !__getopt_initialized) { if (GNoptind == 0) GNoptind = 1; /* Don't scan ARGV[0], the program name. */ optstring = _getopt_initialize (argc, argv, optstring); __getopt_initialized = 1; } /* Test whether ARGV[GNoptind] points to a non-option argument. * Either it does not have option syntax, or there is an environment flag * from the shell indicating it is not an option.

* * This module only parses URIs for the AFS module. The FS URIs fall * into four categories, "chk", "sks", "ksk" and "loc". The first three * categories were named in analogy (!) to Freenet, but they do NOT * work in exactly the same way. They are very similar from the user's * point of view (unique file identifier, subspace, keyword), but the * implementation is rather different in pretty much every detail. * The concrete URI formats are: * *

  • * * First, there are URIs that identify a file. They have the format * "gnunet://fs/chk/HEX1.HEX2.SIZE". These URIs can be used to * download the file. The description, filename, mime-type and other * meta-data is NOT part of the file-URI since a URI uniquely * identifies a resource (and the contents of the file would be the * same even if it had a different description). * *
  • * * The second category identifies entries in a namespace. The format * is "gnunet://fs/sks/NAMESPACE/IDENTIFIER" where the namespace * should be given in HEX. Applications may allow using a nickname * for the namespace if the nickname is not ambiguous. The identifier * can be either an ASCII sequence or a HEX-encoding. If the * identifier is in ASCII but the format is ambiguous and could denote * a HEX-string a "/" is appended to indicate ASCII encoding. * *
  • * * The third category identifies ordinary searches. The format is * "gnunet://fs/ksk/KEYWORD[+KEYWORD]*". Using the "+" syntax * it is possible to encode searches with the boolean "AND" operator. * "+" is used since it indicates a commutative 'and' operation and * is unlikely to be used in a keyword by itself. * *
  • * * The last category identifies a datum on a specific machine. The * format is "gnunet://fs/loc/HEX1.HEX2.SIZE.PEER.SIG.EXPTIME". PEER is * the BinName of the public key of the peer storing the datum. The * signature (SIG) certifies that this peer has this content. * HEX1, HEX2 and SIZE correspond to a 'chk' URI. * *
* * The encoding for hexadecimal values is defined in the hashing.c * module in the gnunetutil library and discussed there. *

This documentation is based on * gnunet.org:/vcs/fsnsg/ats-paper.git/tech-doku/ats-tech-guide.tex * use build_txt.sh to generate plaintext output * * 1 ATS addresses : ATS address management * * This ATS addresses ("addresses") component manages the addresses known to * ATS service and suggests addresses to transport service when it is * interested in address suggestion for a peer. ATS addresses also * instantiates the bandwidth assignment mechanism (solver), notifies it * about changes to addresses and forwards changes to bandwidth assignments * to transport, depending if transport is interested in this change. * * 1.1 Input data * * 1.1.1 Addresses * * Addresses are added by specifying peer ID, plugin, address, address length * and session, if available. ATS information can be specified if available. * * 1.1.2 Networks * * ATS specifies a fix set of networks an address can belong to. For each * network an inbound and outbound quota will be specified. The available * networks and addtional helper varaibles are defined in * gnunet_ats_service.h. At the moment 5 networks are defined: * * GNUNET_ATS_NET_UNSPECIFIED * * GNUNET_ATS_NET_LOOPBACK * * GNUNET_ATS_NET_LAN * * GNUNET_ATS_NET_WAN * * GNUNET_ATS_NET_WLAN * * The total number of networks defined is stored in * GNUNET_ATS_NetworkTypeCount GNUNET_ATS_NetworkType can be used array * initializer for an int array, while GNUNET_ATS_NetworkType is an * initializer for a char array containing a string description of all * networks * * 1.1.3 Quotas * * An inbound and outbound quota for each of the networks mentioned in 1.1.2 * is loaded from ats configuration during initialization. This quota defines * to total amount of inbound and outbound traffic allowed for a specific * network. The configuration values used are in section ats: * * "NETWORK"_QUOTA_IN = * * "NETWORK"_QUOTA_IN = * * You can specify quotas by setting the to a: * * unrestricted: unlimited * * number of bytes: e.g. 10240 * * fancy value: e.g. 64 Kib * * unlimited is defined as GNUNET_ATS_MaxBandwidthString and equivalent to * the value GNUNET_ATS_MaxBandwidth Important predefined values for quotas * are: * * GNUNET_ATS_DefaultBandwidth: 65536 * * GNUNET_ATS_MaxBandwidth: UINT32_MAX * * GNUNET_CONSTANTS_DEFAULT_BW_IN_OUT: 1024 * * Details of loading quotas and default values will be described on * * 1.1.4 Preference values * * 1.2 Data structures used * * Addresse uses struct ATS_Address for each address. The structs are stored * in a linked list and provides a pointer void *solver_information for the * solver to store address specific information. It provides the int values * active which is set to GNUNET_YES if the address is select for transport * use and used, representing that transport service is actively using this * address. Address information are stored in peer, addr, addr_len, plugin. * * 1.3 Initialization * * During initialization a hashmap to store addresses is created. The quotas * for all networks defined for ATS are loaded from configuration. For each * network first the logic will check if the string * GNUNET_ATS_MaxBandwidthString is configured, if not it will try to convert * the configured value as a fancy size and if this fails it will try to use * it as a value_number. If no configuration value is found it will assign * GNUNET_ATS_DefaultBandwidth. The most important step is to load the * configured solver using configuration "[ats]:MODE". Current solvers are * MODE_PROPORTIONAL, MODE_MLP. Interaction is done using a solver API * * 1.4 Solver API * * Solver functions: * * s_init: init the solver with required information * * s_add: add a new address * * s_update: update ATS values or session for an address * * s_get: get prefered address for a peer * * s_del: delete an address * * s_pref: change preference value for a peer * * s_done: shutdown solver * * Callbacks: addresses provides a bandwidth_changed_cb callback to the * solver which is called when bandwidth assigned to peer has changed * * 1.5 Shutdown * * During shutdown all addresses are freed and the solver told to shutdown * * 1.6 Addresses and sessions * * Addresses consist of the address itself and a numerical session. When a * new address without a session is added it has no session, so it gets * session 0 assigned. When an address with a session is added and an address * object with session 0 is found, this object is updated with the session * otherwise a new address object with this session assigned is created. * * 1.6.1 Terminology * * Addresses a1,a2 with session s1, s2 are "exact" if: * (a1 == a2)&&(s1 == s2) * Addresses a1,a2 with session s1, s2 are "equivalent" if: * (a1 == a2)&&((s1 == s2)||(s1 == 0)||(s2 == 0) * * 1.7 Address management * * Transport service notifies ATS about changes to the addresses known to * him. * * 1.7.1 Adding an address * * When transport learns a new address it tells ATS and ATS is telling * addresses about it using GAS_address_add. If not known to addresses it * creates a new address object and calls solver's s_add. ATS information are * deserialized and solver is notified about the session and ATS information * using s_update. * * 1.7.2 Updating an address * * Addresses does an lookup up for the existing address with the given * session. If disassembles included ATS information and notifies the solver * using s_update about the update. * * 1.7.3 Deleting an address * * Addresses does an lookup for the exact address and session and if removes * this address. If session != 0 the session is set to 0 and the address is * kept. If session == 0, the addresses is removed. * * 1.7.4 Requesting an address suggestion * * The address client issues a request address message to be notified about * address suggestions for a specific peer. Addresses asks the solver with * s_get. If no address is available, it will not send a response, otherwise * it will respond with the choosen address. * * 1.7.5 Address suggestions * * Addresses will notify the client automatically on any bandwidth_changed_cb * by the solver if a address suggestion request is pending. If no address is * available it will not respond at all If the client is not interested * anymore, it has to cancel the address suggestion request. * * 1.7.6 Suggestions blocks and reset * * After suggesting an address it is blocked for ATS_BLOCKING_DELTA sec. to * prevent the client from being thrashed. If the client requires immediately * it can reset this block using GAS_addresses_handle_backoff_reset. * * 1.7.7 Marking address in use * * The client can notify addresses that it successfully uses an address and * wants this address to be kept by calling GSA_address_in_use. Adresses will * mark the address as used an notify the solver about the use. * * 1.7.8 Address lifecycle * * * (add address) * * (updated address) || (address in use) * * (delete address) * * 1.8 Bandwidth assignment * * The addresses are used to perform resource allocation operations. ATS * addresses takes care of instantiating the solver configured and notifies * the respective solver about address changes and receives changes to the * bandwidth assignment from the solver. The current bandwidth assignment is * sent to transport. The specific solvers will be described in the specific * section. * * 1.9 Changing peer preferences * * The bandwidth assigned to a peer can be influenced by setting a preference * for a peer.

This documentation is based on * gnunet.org:/vcs/fsnsg/ats-paper.git/tech-doku/ats-tech-guide.tex * use build_txt.sh to generate plaintext output * * The MLP solver (mlp) tries to finds an optimal bandwidth assignmentby * optimizing an mixed integer programming problem. The MLP solver uses a * number of constraints to find the best adddress for a peer and an optimal * bandwidth assignment. mlp uses the GNU Linear Programming Kit to solve the * MLP problem. * * We defined a constraint system to find an optimal bandwidth assignment. * This constraint system uses as an input data addresses, bandwidth quotas, * preferences and quality values. This constraint system is stored in an * matrix based equotation system. * * 5 Using GLPK * * A (M)LP problem consists of a target function to optimizes, constraints * and rows and columns. FIXME GLP uses three arrays to index the matrix: two * integer arrays storing the row and column indices in the matrix and an * float array to store the coeeficient. * * To solve the problem we first find an initial solution for the LP problem * using the LP solver and then find an MLP solution based on this solution * using the MLP solver. * * Solving (M)LP problems has the property that finding an initial solution * for the LP problem is computationally expensive and finding the MLP * solution is cheaper. This is especially interesting an existing LP * solution can be reused if only coefficients in the matrix have changed * (addresses updated). Only when the problem size changes (addresses added * or deleted) a new LP solution has to be found. * * Intended usage * The mlp solver solves the bandwidth assignment problem only on demand when * an address suggestion is requested. When an address is requested mlp the * solves the mlp problem and if the active address or the bandwidth assigned * changes it calls the callback to addresses. The mlp solver gets notified * about new addresses (adding sessions), removed addresses (address * deletions) and address updates. To benefit from the mlp properties * mentioned in section 5 the solver rembers if since the last solution * addresses were added or deleted (problem size changed, problem has to be * rebuild and solved from sratch) or if addresses were updated and the * existing solution can be reused. * * 5.1 Input data * * The quotas for each network segment are passed by addresses. MLP can be * adapted using configuration settings and uses the following parameters: * * MLP_MAX_DURATION: * Maximum duration for a MLP solution procees (default: 3 sec.) * * MLP_MAX_ITERATIONS: * Maximum number of iterations for a MLP solution process (default: * 1024) * * MLP_MIN_CONNECTIONS: * Minimum number of desired connections (default: 4) * * MLP_MIN_BANDWIDTH: * Minimum amount of bandwidth assigned to an address (default: 1024) * * MLP_COEFFICIENT_D: * Diversity coefficient (default: 1.0) * * MLP_COEFFICIENT_R: * Relativity coefficient (default: 1.0) * * MLP_COEFFICIENT_U: * Utilization coefficient (default: 1.0) * * MLP_COEFFICIENT_D: * Diversity coefficient (default: 1.0) * * MLP_COEFFICIENT_QUALITY_DELAY: * Quality delay coefficient (default: 1.0) * * MLP_COEFFICIENT_QUALITY_DISTANCE: * Quality distance coefficient (default: 1.0) * * MLP_COEFFICIENT_QUALITY_DISTANCE: * Quality distance coefficient (default: 1.0) * * MLP_COEFFICIENT_QUALITY_DISTANCE: * Quality distance coefficient (default: 1.0) * * MLP_COEFFICIENT_QUALITY_DISTANCE: * Quality distance coefficient (default: 1.0) * * 5.2 Data structures used * * mlp has for each known peer a struct ATS_Peer containing information about * a specific peer. The address field solver_information contains information * about the mlp properties of this address. * * 5.3 Initializing * * During initialization mlp initializes the GLPK libray used to solve the * MLP problem: it initializes the glpk environment and creates an initial LP * problem. Next it loads the configuration values from the configuration or * uses the default values configured in -addresses_mlp.h. The quotas used * are given by addresses but may have to be adjusted. mlp uses a upper limit * for the bandwidth assigned called BIG M and a minimum amount of bandwidth * an address gets assigned as well as a minium desired number of * connections. If the configured quota is bigger than BIG M, it is reduced * to BIG M. If the configured quota is smaller than MLP_MIN_CONNECTIONS * *MLP_MIN_BANDWIDTH it is increased to this value. * * 5.4 Shutdown */ #define LOG(kind,...)

GNUNET_log_from (kind, "ats-proportional",__VA_ARGS__) /** * * NOTE: Do not change this documentation. This documentation is based * on gnunet.org:/vcs/fsnsg/ats-paper.git/tech-doku/ats-tech-guide.tex * use build_txt.sh to generate plaintext output * * ATS addresses : proportional solver * * The proportional solver ("proportional") distributes the available * bandwidth fair over all the addresses influenced by the * preference values. For each available network type an in- and * outbound quota is configured and the bandwidth available in * these networks is distributed over the addresses. The solver * first assigns every addresses the minimum amount of bandwidth * GNUNET_CONSTANTS_DEFAULT_BW_IN_OUT and then distributes the * remaining bandwidth available according to the preference * values. For each peer only a single address gets bandwidth * assigned and only one address marked as active. The most * important functionality for the solver is implemented in: * * find_address_it is an hashmap iterator returning the prefered * address for an peer * update_quota_per_network distributes * available bandwidth for a network over active addresses * * Changes to addresses automatically have an impact on the the * bandwidth assigned to other addresses in the same network since * the solver distributes the remaining bandwidth over the * addresses in the network. When changes to the addresses occur, * the solver first performs the changes, like adding or deleting * addresses, and then updates bandwidth assignment for the * affected network. Bandwidth assignment is only recalculated on * demand when an address is requested by a client for a peer or * when the addresses available have changed or an address changed * the network it is located in. When the bandwidth assignment has * changed the callback is called with the new bandwidth * assignments. The bandwidth distribution for a network is * recalculated due to: * address suggestion requests * address * deletions * address switching networks during address update * * preference changes * * 3.1 Data structures used * * For each ATS network (e.g. WAN, LAN, loopback) a struct Network * is used to specify network related information as total adresses * and active addresses in this network and the configured in- and * outbound quota. Each network also contains a list of addresses * added to the solver located in this network. The proportional * solver uses the addresses' solver_information field to store the * proportional network it belongs to for each address. * * 3.2 Initializing * * When the proportional solver is initialized the solver creates a * new solver handle and initializes the network structures with * the quotas passed from addresses and returns the handle solver. * * 3.3 Adding an address * * When a new address is added to the solver using s_add, a lookup * for the network for this address is done and the address is * enqueued in in the linked list of the network. * * 3.4 Updating an address * * The main purpose of address updates is to update the ATS * information for addresse selection. Important for the proportional * solver is when an address switches network it is located * in. This is common because addresses added by transport's * validation mechanism are commonly located in * GNUNET_ATS_NET_UNSPECIFIED. Addresses in validation are located * in this network type and only if a connection is successful on * return of payload data transport switches to the real network * the address is located in. When an address changes networks it * is first of all removed from the old network using the solver * API function GAS_proportional_address_delete and the network in * the address struct is updated. A lookup for the respective new * proportional network is done and stored in the addresse's * solver_information field. Next the address is re-added to the * solver using the solver API function * GAS_proportional_address_add. If the address was marked as in * active, the solver checks if bandwidth is available in the * network and if yes sets the address to active and updates the * bandwidth distribution in this network. If no bandwidth is * available it sets the bandwidth for this address to 0 and tries * to suggest an alternative address. If an alternative address was * found, addresses' callback is called for this address. * * 3.5 Deleting an address * * When an address is removed from the solver, it removes the * respective address from the network and if the address was * marked as active, it updates the bandwidth distribution for this * network. * * 3.6 Requesting addresses * * When an address is requested for a peer the solver performs a * lookup for the peer entry in addresses address hashmap and * selects the best address. The selection of the most suitable * address is done in the find_address_it hashmap iterator * described in detail in section 3.7. If no address is returned, * no address can be suggested at the moment. If the address * returned is marked as active, the solver can return this * address. If the address is not marked as active, the solver * checks if another address belongign to this peer is marked as * active and marks the address as inactive, updates the bandwidth * for this address to 0, call the bandwidth changed callback for * this address due to the change and updates quota assignment for * the addresse's network. the now in-active address is belonging * to. The solver marks the new address as active and updates the * bandwidth assignment for this network. * * 3.7 Choosing addresses * * Choosing the best possible address for suggestion is done by * iterating over all addresses of a peer stored in addresses' * hashmap and using the hashmap iterator find_address_it to select * the best available address. Several checks are done when an * address is selected. First if this address is currently blocked * by addresses from being suggested. An address is blocked for the * duration of ATS_BLOCKING_DELTA when it is suggested to * transport. Next it is checked if at least * GNUNET_CONSTANTS_DEFAULT_BW_IN_OUT bytes bandwidth is available * in the addresse's network, because suggesting an address without * bandwidth does not make sense. This also ensures that all active * addresses in this network get at least the minimum amount of * bandwidth assigned. In the next step the solver ensures that for * tcp connections inbound connections are prefered over outbound * connections. In the next stet the solver ensures that * connections are prefered in the following order: * connections * are already established and have bandwidth assigned * * connections with a shorter distance * connectes have a shorter * latency * * 3.8 Changing preferences * * 3.9 Shutdown * * During shutdown all network entries and aging processes are * destroyed and freed. * * * OLD DOCUMENTATION * * This solver assigns in and outbound bandwidth equally for all * addresses in specific network type (WAN, LAN) based on configured * in and outbound quota for this network. * * The solver is notified by addresses about changes to the addresses * and recalculates the bandwith assigned if required. The solver * notifies addresses by calling the GAS_bandwidth_changed_cb * callback. * * - Initialization * * * * * For each peer only a single is selected and marked as "active" in the address * struct. * * E.g.: * * You have the networks WAN and LAN and quotas * WAN_TOTAL_IN, WAN_TOTAL_OUT * LAN_TOTAL_IN, LAN_TOTAL_OUT * * If you have x addresses in the network segment LAN, the quotas are * QUOTA_PER_ADDRESS = LAN_TOTAL_OUT / x * * Quotas are automatically recalculated and reported back when addresses are * - requested * */ #define PREF_AGING_INTERVAL GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_SECONDS, 10) #define PREF_AGING_FACTOR 0.95 #define DEFAULT_REL_PREFERENCE 1.0 #define DEFAULT_ABS_PREFERENCE 0.0 #define MIN_UPDATE_INTERVAL GNUNET_TIME_relative_multiply (GNUNET_TIME_UNIT_SECONDS, 10) /** * A handle for the proportional solver */ struct GAS_PROPORTIONAL_Handle { struct GNUNET_ATS_PluginEnvironment *env;

This documentation is based on * gnunet.org:/vcs/fsnsg/ats-paper.git/tech-doku/ats-tech-guide.tex * use build_txt.sh to generate plaintext output * * 1 ATS addresses : ATS address management * * This ATS addresses ("addresses") component manages the addresses known to * ATS service and suggests addresses to transport service when it is * interested in address suggestion for a peer. ATS addresses also * instantiates the bandwidth assignment mechanism (solver), notifies it * about changes to addresses and forwards changes to bandwidth assignments * to transport, depending if transport is interested in this change. * * 1.1 Input data * * 1.1.1 Addresses * * Addresses are added by specifying peer ID, plugin, address, address length * and session, if available. ATS information can be specified if available. * * 1.1.2 Networks * * ATS specifies a fix set of networks an address can belong to. For each * network an inbound and outbound quota will be specified. The available * networks and addtional helper varaibles are defined in * gnunet_ats_service.h. At the moment 5 networks are defined: * * GNUNET_ATS_NET_UNSPECIFIED * * GNUNET_ATS_NET_LOOPBACK * * GNUNET_ATS_NET_LAN * * GNUNET_ATS_NET_WAN * * GNUNET_ATS_NET_WLAN * * The total number of networks defined is stored in * GNUNET_ATS_NetworkTypeCount GNUNET_ATS_NetworkType can be used array * initializer for an int array, while GNUNET_ATS_NetworkType is an * initializer for a char array containing a string description of all * networks * * 1.1.3 Quotas * * An inbound and outbound quota for each of the networks mentioned in 1.1.2 * is loaded from ats configuration during initialization. This quota defines * to total amount of inbound and outbound traffic allowed for a specific * network. The configuration values used are in section ats: * * "NETWORK"_QUOTA_IN = * * "NETWORK"_QUOTA_IN = * * You can specify quotas by setting the to a: * * unrestricted: unlimited * * number of bytes: e.g. 10240 * * fancy value: e.g. 64 Kib * * unlimited is defined as GNUNET_ATS_MaxBandwidthString and equivalent to * the value GNUNET_ATS_MaxBandwidth Important predefined values for quotas * are: * * GNUNET_ATS_DefaultBandwidth: 65536 * * GNUNET_ATS_MaxBandwidth: UINT32_MAX * * GNUNET_CONSTANTS_DEFAULT_BW_IN_OUT: 1024 * * Details of loading quotas and default values will be described on * * 1.1.4 Preference values * * 1.2 Data structures used * * Addresse uses struct ATS_Address for each address. The structs are stored * in a linked list and provides a pointer void *solver_information for the * solver to store address specific information. It provides the int values * active which is set to GNUNET_YES if the address is select for transport * use and used, representing that transport service is actively using this * address. Address information are stored in peer, addr, addr_len, plugin. * * 1.3 Initialization * * During initialization a hashmap to store addresses is created. The quotas * for all networks defined for ATS are loaded from configuration. For each * network first the logic will check if the string * GNUNET_ATS_MaxBandwidthString is configured, if not it will try to convert * the configured value as a fancy size and if this fails it will try to use * it as a value_number. If no configuration value is found it will assign * GNUNET_ATS_DefaultBandwidth. The most important step is to load the * configured solver using configuration "[ats]:MODE". Current solvers are * MODE_PROPORTIONAL, MODE_MLP. Interaction is done using a solver API * * 1.4 Solver API * * Solver functions: * * s_init: init the solver with required information * * s_add: add a new address * * s_update: update ATS values or session for an address * * s_get: get prefered address for a peer * * s_del: delete an address * * s_pref: change preference value for a peer * * s_done: shutdown solver * * Callbacks: addresses provides a bandwidth_changed_cb callback to the * solver which is called when bandwidth assigned to peer has changed * * 1.5 Shutdown * * During shutdown all addresses are freed and the solver told to shutdown * * 1.6 Addresses and sessions * * Addresses consist of the address itself and a numerical session. When a * new address without a session is added it has no session, so it gets * session 0 assigned. When an address with a session is added and an address * object with session 0 is found, this object is updated with the session * otherwise a new address object with this session assigned is created. * * 1.6.1 Terminology * * Addresses a1,a2 with session s1, s2 are "exact" if: * (a1 == a2)&&(s1 == s2) * Addresses a1,a2 with session s1, s2 are "equivalent" if: * (a1 == a2)&&((s1 == s2)||(s1 == 0)||(s2 == 0) * * 1.7 Address management * * Transport service notifies ATS about changes to the addresses known to * him. * * 1.7.1 Adding an address * * When transport learns a new address it tells ATS and ATS is telling * addresses about it using GAS_address_add. If not known to addresses it * creates a new address object and calls solver's s_add. ATS information are * deserialized and solver is notified about the session and ATS information * using s_update. * * 1.7.2 Updating an address * * Addresses does an lookup up for the existing address with the given * session. If disassembles included ATS information and notifies the solver * using s_update about the update. * * 1.7.3 Deleting an address * * Addresses does an lookup for the exact address and session and if removes * this address. If session != 0 the session is set to 0 and the address is * kept. If session == 0, the addresses is removed. * * 1.7.4 Requesting an address suggestion * * The address client issues a request address message to be notified about * address suggestions for a specific peer. Addresses asks the solver with * s_get. If no address is available, it will not send a response, otherwise * it will respond with the choosen address. * * 1.7.5 Address suggestions * * Addresses will notify the client automatically on any bandwidth_changed_cb * by the solver if a address suggestion request is pending. If no address is * available it will not respond at all If the client is not interested * anymore, it has to cancel the address suggestion request. * * 1.7.6 Suggestions blocks and reset * * After suggesting an address it is blocked for ATS_BLOCKING_DELTA sec. to * prevent the client from being thrashed. If the client requires immediately * it can reset this block using GAS_addresses_handle_backoff_reset. * * 1.7.7 Marking address in use * * The client can notify addresses that it successfully uses an address and * wants this address to be kept by calling GSA_address_in_use. Adresses will * mark the address as used an notify the solver about the use. * * 1.7.8 Address lifecycle * * * (add address) * * (updated address) || (address in use) * * (delete address) * * 1.8 Bandwidth assignment * * The addresses are used to perform resource allocation operations. ATS * addresses takes care of instantiating the solver configured and notifies * the respective solver about address changes and receives changes to the * bandwidth assignment from the solver. The current bandwidth assignment is * sent to transport. The specific solvers will be described in the specific * section. * * 1.9 Changing peer preferences * * The bandwidth assigned to a peer can be influenced by setting a preference * for a peer. The prefernce will be given to to the solver with s_pref which * has to take care of the preference value */ /** * Pending Address suggestion requests */ struct GAS_Addresses_Suggestion_Requests { /** * Next in DLL */ struct GAS_Addresses_Suggestion_Requests *next;

It will force traffic to be in 'ad-hoc' mode, use the * proper MAC address of the WLAN interface and use a GNUnet-specific * SSID (and a GNUnet-specific SNAP header). It only takes a single * argument, which is the name of the WLAN interface to use. The * program detects if the interface is not a WLAN interface and exits * with an error in that case. * * Once initialized, the program will first send a 'struct * GNUNET_TRANSPORT_WLAN_HelperControlMessage' to 'stdout'. That * message contains the MAC address of the WLAN interface. It will * then read messages from the WLAN interface and send them together * with performance information as 'struct * GNUNET_TRANSPORT_WLAN_RadiotapReceiveMessage' messages to 'stdout'. * Furthermore, it will read a stream of messages from 'stdin' that * have the format from 'struct * GNUNET_TRANSPORT_WLAN_RadiotapSendMessage'. Those messages will * then be sent via the WLAN interface; however, the sender MAC * address will be forced to be the correct address from our WLAN * card. If 'stdin' closes, receiving from the WLAN interface will * continue. If 'stdout' causes a SIGPIPE, the process dies from the * signal. Errors cause an error message to be reported to 'stderr', * in most cases the process also exits (with status code '1'). The * program never terminates normally; it is safe to kill the * process with SIGTERM or SIGKILL at any time. * * Since it uses RAW sockets, the binary must be installed SUID or run * as 'root'.

With * blacklisting it is possible to deny connections to specific peers of * to use a specific plugin to a specific peer. Peers can be blacklisted using * the configuration or a blacklist client can be asked. * * To blacklist peers using the configuration you have to add a section to your * configuration containing the peer id of the peer to blacklist and the plugin * if required. * * Example: * To blacklist connections to P565... on peer AG2P... using tcp add: * [transport-blacklist-AG2PHES1BARB9IJCPAMJTFPVJ5V3A72S3F2A8SBUB8DAQ2V0O3V8G6G2JU56FHGFOHMQVKBSQFV98TCGTC3RJ1NINP82G0RC00N1520] * P565723JO1C2HSN6J29TAQ22MN6CI8HTMUU55T0FUQG4CMDGGEQ8UCNBKUMB94GC8R9G4FB2SF9LDOBAJ6AMINBP4JHHDD6L7VD801G = tcp * * To blacklist connections to P565... on peer AG2P... using all plugins add: * [transport-blacklist-AG2PHES1BARB9IJCPAMJTFPVJ5V3A72S3F2A8SBUB8DAQ2V0O3V8G6G2JU56FHGFOHMQVKBSQFV98TCGTC3RJ1NINP82G0RC00N1520] * P565723JO1C2HSN6J29TAQ22MN6CI8HTMUU55T0FUQG4CMDGGEQ8UCNBKUMB94GC8R9G4FB2SF9LDOBAJ6AMINBP4JHHDD6L7VD801G = * * You can also add a blacklist client usign the blacklist api.

MySQL 5.0.46 promises to fix a bug * in MyISAM that is causing us grief. At the time of this writing, * that version is yet to be released. In anticipation, the code * will use MyISAM with 5.0.46 (and higher). If you run such a * version, please run "make check" to verify that the MySQL bug * was actually fixed in your version (and if not, change the * code below to use MyISAM for gn071). * * HIGHLIGHTS * * Pros * + On up-to-date hardware where mysql can be used comfortably, this * module will have better performance than the other db choices * (according to our tests). * + Its often possible to recover the mysql database from internal * inconsistencies. The other db choices do not support repair! * Cons * - Memory usage (Comment: "I have 1G and it never caused me trouble") * - Manual setup * * MANUAL SETUP INSTRUCTIONS * * 1) in gnunet.conf, set * @verbatim [datastore] DATABASE = "mysql" @endverbatim * 2) Then access mysql as root, * @verbatim $ mysql -u root -p @endverbatim * and do the following. [You should replace $USER with the username * that will be running the gnunetd process]. * @verbatim CREATE DATABASE gnunet; GRANT select,insert,update,delete,create,alter,drop,create temporary tables ON gnunet.* TO $USER@localhost; SET PASSWORD FOR $USER@localhost=PASSWORD('$the_password_you_like'); FLUSH PRIVILEGES; @endverbatim * 3) In the $HOME directory of $USER, create a ".my.cnf" file * with the following lines * @verbatim [client] user=$USER password=$the_password_you_like @endverbatim * * Thats it. Note that .my.cnf file is a security risk unless its on * a safe partition etc. The $HOME/.my.cnf can of course be a symbolic * link. Even greater security risk can be achieved by setting no * password for $USER. Luckily $USER has only priviledges to mess * up GNUnet's tables, nothing else (unless you give him more, * of course).

* * 4) Still, perhaps you should briefly try if the DB connection * works. First, login as $USER. Then use, * * @verbatim $ mysql -u $USER -p $the_password_you_like mysql> use gnunet; @endverbatim * * If you get the message "Database changed" it probably works. * * [If you get "ERROR 2002: Can't connect to local MySQL server * through socket '/tmp/mysql.sock' (2)" it may be resolvable by * "ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock" * so there may be some additional trouble depending on your mysql setup.] * * REPAIRING TABLES * * - Its probably healthy to check your tables for inconsistencies * every now and then. * - If you get odd SEGVs on gnunetd startup, it might be that the mysql * databases have been corrupted. * - The tables can be verified/fixed in two ways; * 1) by running mysqlcheck -A, or * 2) by executing (inside of mysql using the GNUnet database): * @verbatim mysql> REPAIR TABLE gn090; @endverbatim * * PROBLEMS? * * If you have problems related to the mysql module, your best * friend is probably the mysql manual. The first thing to check * is that mysql is basically operational, that you can connect * to it, create tables, issue queries etc. */ #include "platform.h" #include "gnunet_datastore_plugin.h" #include "gnunet_util_lib.h" #include "gnunet_mysql_lib.h" #define MAX_DATUM_SIZE 65536 /** * Context for all functions in this plugin. */ struct Plugin { /** * Our execution environment. */ struct GNUNET_DATASTORE_PluginEnvironment *env; /** * Handle to talk to MySQL. */ struct GNUNET_MYSQL_Context *mc; /** * Prepared statements. */ #define INSERT_ENTRY "INSERT INTO gn090 (repl,type,prio,anonLevel,expire,rvalue,hash,vhash,value) VALUES (?,?,?,?,?,?,?,?,?)" struct GNUNET_MYSQL_StatementHandle *insert_entry; #define DELETE_ENTRY_BY_UID "DELETE FROM gn090 WHERE uid=?" struct GNUNET_MYSQL_StatementHandle *delete_entry_by_uid; #define COUNT_ENTRY_BY_HASH "SELECT count(*) FROM gn090 FORCE INDEX (idx_hash) WHERE hash=?" struct GNUNET_MYSQL_StatementHandle *count_entry_by_hash; #define SELECT_ENTRY_BY_HASH "SELECT type,prio,anonLevel,expire,hash,value,uid FROM gn090 FORCE INDEX (idx_hash) WHERE hash=?

This hash is * compared in distance to the peer identity to choose an offset. The * closer the peer identity to the hashed timestamp, the earlier the * peer sends out a "nearest peer" message. The closest peer's * message should thus be received before any others, which stops * those peer from sending their messages at a later duration. So * every peer should receive the same nearest peer message, and from * this can calculate the expected number of peers in the network. */ #include "platform.h" #include #include "gnunet_util_lib.h" #include "gnunet_constants.h" #include "gnunet_protocols.h" #include "gnunet_signatures.h" #include "gnunet_statistics_service.h" #include "gnunet_core_service.h" #include "gnunet_nse_service.h" #if ENABLE_NSE_HISTOGRAM #include "gnunet_testbed_logger_service.h" #endif #include "nse.h" #include /** * Should messages be delayed randomly?

We then * allow interacting with our virtual interface via stdin/stdout. * @author Philipp Tölke * @author Christian Grothoff * * This program alters the Linux firewall rules so that DNS traffic * that ordinarily exits the system can be intercepted and managed by * a virtual interface. In order to achieve this, DNS traffic is * marked with the DNS_MARK given in below and re-routed to a custom * table with the DNS_TABLE ID given below. Systems and * administrators must take care to not cause conflicts with these * values (it was deemed safest to hardcode them as passing these * values as arguments might permit messing with arbitrary firewall * rules, which would be dangerous). Traffic coming from the same * group ID as the effective group ID that this process is running * as is not intercepted. * * The code first sets up the virtual interface, then begins to * redirect the DNS traffic to it, and then on errors or SIGTERM shuts * down the virtual interface and removes the rules for the traffic * redirection. * * * Note that having this binary SUID is only partially safe: it will * allow redirecting (and intercepting / mangling) of all DNS traffic * originating from this system by any user who is able to run it. * Furthermore, this code will make it trivial to DoS all DNS traffic * originating from the current system, simply by sending it to * nowhere (redirect stdout to /dev/null). * * Naturally, neither of these problems can be helped as this is the * fundamental purpose of the binary. Certifying that this code is * "safe" thus only means that it doesn't allow anything else (such * as local priv. escalation, etc.). * * The following list of people have reviewed this code and considered * it safe (within specifications) since the last modification (if you * reviewed it, please have your name added to the list): * * - Christian Grothoff */ #include "platform.h" #include /** * Need 'struct GNUNET_MessageHeader'. */ #include "gnunet_crypto_lib.h" #include "gnunet_common.h" /** * Need DNS message types. */ #include "gnunet_protocols.h" /** * Maximum size of a GNUnet message (GNUNET_SERVER_MAX_MESSAGE_SIZE) */ #define MAX_SIZE 65536 #ifndef _LINUX_IN6_H /** * This is in linux/include/net/ipv6.h, but not always exported... */ struct in6_ifreq { struct in6_addr ifr6_addr; uint32_t ifr6_prefixlen; unsigned int ifr6_ifindex; }; #endif /** * Name and full path of IPTABLES binary. */ static const char *sbin_iptables; /** * Name and full path of sysctl binary */ static const char *sbin_sysctl; /** * Name and full path of IPTABLES binary. */ static const char *sbin_ip; /** * Port for DNS traffic. */ #define DNS_PORT "53" /** * Marker we set for our hijacked DNS traffic.

Furthermore, we let the OS pick a * source port, opening up to 128 sockets per address family (IPv4 or * IPv6). Those sockets are closed if they are not in use for 5s * (which means they will be freshly randomized afterwards). For new * requests, we pick a random slot in the array with 128 socket slots * (and re-use an existing socket if the slot is still in use). Thus * each request will be given one of 128 random source ports, and the * 128 random source ports will also change "often" (less often if the * system is very busy, each time if we are mostly idle). At the same * time, the system will never use more than 256 UDP sockets. */ #include "platform.h" #include "gnunet_util_lib.h" #include "gnunet_applications.h" #include "gnunet_constants.h" #include "gnunet_protocols.h" #include "gnunet_signatures.h" #include "dns.h" #include "gnunet_dns_service.h" #include "gnunet_dnsparser_lib.h" #include "gnunet_dnsstub_lib.h" #include "gnunet_statistics_service.h" #include "gnunet_tun_lib.h" /** * Port number for DNS */ #define DNS_PORT 53 /** * Generic logging shorthand */ #define LOG(kind, ...) \ GNUNET_log_from (kind, "dns", __VA_ARGS__); /** * Phases each request goes through. */ enum RequestPhase { /** * Request has just been received. */ RP_INIT, /** * Showing the request to all monitor clients.

Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

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.

Then, you can compile GNUnet with make After that, run (if necessary as 'root') make install to install everything. Each GNUnet user should be added to the 'gnunet' group (may require fresh login to come into effect): adduser USERNAME gnunet (run the above command as root once for each of your users, replacing "USERNAME" with the respective login names). If you have a global IP address, no further configuration is required. Optionally, download and compile gnunet-gtk to get a GUI for file-sharing and configuration. This is particularly recommended if your network setup is non-trivial, as gnunet-setup can be used to test in the GUI if your network configuration is working. gnunet-setup should be run as the "gnunet" user under X. As it does very little with the network, running it as "root" is likely also harmless. You can also run it as a normal user, but then you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's home directory in the end. Once you have configured your peer, run (as the 'gnunet' user) gnunet-arm -s to start the peer. You can then run the various GNUnet-tools as your "normal" user (who should only be in the group 'gnunet'). ********************************************]) gnunet-0.10.1/AUTHORS0000644000175000017500000000773612274162761011107 00000000000000Program: GNUnet Homepage: https://gnunet.org/ Maintainer: Christian Grothoff Bug reports: https://gnunet.org/bugs/ Security related bug reports: security@gnunet.org License: some GPLv2+, mostly GPLv3+ Primary developers (0.9.x series): Alejandra Morales Andreas Fuchs Bart Polot Bruno Cabral Christian Fuchs Christian Grothoff Claudiu Olteanu David Barksdale Fabian Oehlmann Florian Dold Gabor X Toth LRN Martin Schanzenbach Matthias Wachs Maximilian Szengel Nils Durner Simon Dieterle Sree Harsha Totakura --- http://sreeharsha.totakura.in/ Stephan A.

We must quote the arguments since Win32 CreateProcess() interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a special way: - Space and tab are interpreted as delimiters. They are not treated as delimiters if they are surrounded by double quotes: "...". - Unescaped double quotes are removed from the input. Their only effect is that within double quotes, space and tab are treated like normal characters. - Backslashes not followed by double quotes are not special. - But 2*n+1 backslashes followed by a double quote become n backslashes followed by a double quote (n >= 0): \" -> " \\\" -> \" \\\\\" -> \\" */ #define SHELL_SPECIAL_CHARS "\"\\ \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" #define SHELL_SPACE_CHARS " \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" char ** prepare_spawn (char **argv) { size_t argc; char **new_argv; size_t i; /* Count number of arguments. */ for (argc = 0; argv[argc] != NULL; argc++) ; /* Allocate new argument vector. */ new_argv = XMALLOC (char *, argc + 1); /* Put quoted arguments into the new argument vector. */ for (i = 0; i < argc; i++) { const char *string = argv[i]; if (string[0] == '\0') new_argv[i] = xstrdup ("\"\""); else if (strpbrk (string, SHELL_SPECIAL_CHARS) != NULL) { int quote_around = (strpbrk (string, SHELL_SPACE_CHARS) != NULL); size_t length; unsigned int backslashes; const char *s; char *quoted_string; char *p; length = 0; backslashes = 0; if (quote_around) length++; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') length += backslashes + 1; length++; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) length += backslashes + 1; quoted_string = XMALLOC (char, length + 1); p = quoted_string; backslashes = 0; if (quote_around) *p++ = '"'; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') { unsigned int j; for (j = backslashes + 1; j > 0; j--) *p++ = '\\'; } *p++ = c; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) { unsigned int j; for (j = backslashes; j > 0; j--) *p++ = '\\'; *p++ = '"'; } *p = '\0'; new_argv[i] = quoted_string; } else new_argv[i] = (char *) string; } new_argv[argc] = NULL; return new_argv; } EOF ;; esac cat <<"EOF" void lt_dump_script (FILE* f) { EOF func_emit_wrapper yes | $SED -n -e ' s/^\(.\{79\}\)\(..*\)/\1\ \2/ h s/\([\\"]\)/\\\1/g s/$/\\n/ s/\([^\n]*\).*/ fputs ("\1", f);/p g D' cat <<"EOF" } EOF } # end: func_emit_cwrapperexe_src # func_win32_import_lib_p ARG # True if ARG is an import lib, as indicated by $file_magic_cmd func_win32_import_lib_p () { $opt_debug case `eval $file_magic_cmd \"\$1\" 2>/dev/null | $SED -e 10q` in *import*) : ;; *) false ;; esac } # func_mode_link arg... func_mode_link () { $opt_debug case $host in *-*-cygwin* | *-*-mingw* | *-*-pw32* | *-*-os2* | *-cegcc*) # It is impossible to link a dll without this setting, and # we shouldn't force the makefile maintainer to figure out # which system we are compiling for in order to pass an extra # flag for every libtool invocation. # allow_undefined=no # FIXME: Unfortunately, there are problems with the above when trying # to make a dll which has undefined symbols, in which case not # even a static library is built.

key files .SH SYNOPSIS .B gnunet\-ecc .RI [ options ] FILENAME .br .SH DESCRIPTION \fBgnunet\-ecc\fP can be used to create an ECC private key and to print the corresponding public key. You must specify a filename containing an ECC private key in GNUnet format as an argument. If the file does not exist, gnunet\-ecc will create a key. This may then take a while. If the option \-p is given, the corresponding public key will be printed to the console. .SH OPTIONS .B .IP "\-g COUNT, \-\-generate-keys=COUNT" Create COUNT public-private key pairs and write them to FILENAME.

It can be used in combination with browsers that support the SOCKS 4a protocol. The proxy will perform SSL authentication of GNS names and rewrite GNS enabled HTML content. To assert the validity of GNS names a local root CA certificate has to be generated that is used by the proxy.

The keywords are case\-sensitive. gnunet\-search can be used both for a search in the global namespace as well as for searching a private subspace. .TP \fB\-a \fILEVEL\fR, \fB\-\-anonymity=\fILEVEL\fR The \fB\-a\fR option can be used to specify additional anonymity constraints. If set to 0, GNUnet will try to download the file as fast as possible, including using non-anonymous methods. If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity). However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time infer data about your identity. You can gain better privacy by specifying a higher level of anonymity, which increases the amount of cover traffic your own traffic will get, at the expense of performance. Note that your download performance is not only determined by your own anonymity level, but also by the anonymity level of the peers publishing the file. So even if you download with anonymity level 0, the peers publishing the data might be sharing with a higher anonymity level, which in this case will determine performance. Also, peers that cache content in the network always use anonymity level 1. This option can be used to limit requests further than that. In particular, you can require GNUnet to receive certain amounts of traffic from other peers before sending your queries. This way, you can gain very high levels of anonymity \- at the expense of much more traffic and much higher latency. So set it only if you really believe you need it. The definition of ANONYMITY\-RECEIVE is the following. 0 means no anonymity is required. Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the local user, leaving 'v-1' bytes of cover traffic per byte on the wire. Thus, if GNUnet routes n bytes of messages from foreign peers (using anonymous routing), it may originate n/(v-1) bytes of queries in the same time\-period. The time\-period is twice the average delay that GNUnet defers forwarded queries. The default is 1 and this should be fine for most users. Also notice that if you choose very large values, you may end up having no throughput at all, especially if many of your fellow GNUnet\-peers all do the same. .TP \fB\-c \fIFILENAME\fR, \fB\-\-config=\fIFILENAME\fR use config file (defaults: ~/.config/gnunet.conf) .TP \fB\-h\fR, \fB\-\-help\fR print help page .TP \fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=\fILOGLEVEL\fR Change the loglevel.

The value given must be a number followed by a space and a time unit, for example "500 ms". Note that the quotes are required on the shell.

The URI can have the format for a namespace search or for a keyword search. For a namespace search, the format is gnunet://fs/sks/NAMESPACE/IDENTIFIER. For a keyword search, use gnunet://fs/ksk/KEYWORD[+KEYWORD]*. If the format does not correspond to a GNUnet URI, GNUnet will automatically assume that keywords are supplied directly. If multiple keywords are passed, gnunet-search will look for content matching any of the keywords. The prefix "+" makes a keyword mandatory. # gnunet\-search "Das Kapital" searches for content matching the keyword "Das Kapital". Whereas # gnunet\-search +Das +Kapital Searches for content matching both mandatory keywords "Das" and "Kapital". Search results are printed by gnunet\-search like this: .P .ad l gnunet\-download \-o "COPYING" gnunet://fs/chk/HASH1.HASH2.SIZE Description: The GNU General Public License Mime-type: text/plain .ad b The first line contains the command to run to download the file.

A GNUnet directory is a binary file that contains a list of GNUnet file\-sharing URIs and meta data. The names of the directory files must be passed as command\-line arguments to gnunet\-directory. .TP \fB\-c \fIFILENAME\fR, \fB\-\-config=FILENAME\fR configuration file to use (useless option since gnunet\-directory does not really depend on any configuration options) .TP \fB\-h\fR, \fB\-\-help\fR print help page .TP \fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=LOGLEVEL\fR Change the loglevel. Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG. .TP \fB\-v\fR, \fB\-\-version\fR print the version number .SH NOTES A GNUnet directory is a file containing a list of GNUnet URIs and meta data. The keys can point to files, other directories or files in namespaces. In other words, a GNUnet directory is similar to UNIX directories. The difference to tar and zip is that GNUnet directory does not contain the actual files (except if they are really small, in which case they may be inlined), just symbolic (links), similar to directories with symbolic links in UNIX filesystems. The benefit is that the individual files can be retrieved separately (if desired) and if some of the files are inserted to another node in GNUnet, this just increases their availability but does not produce useless duplicates (for example, it is a better idea to publish a collection of pictures or compressed sound files using a GNUnet directory instead of processing them with archivers such as tar or zip first). Directories can contain arbitrary meta data for each file. If a directory has missing blocks (for example, some blocks failed to download), GNUnet is typically able to retrieve information about other files in the directory. Files in a GNUnet directory have no particular order; the GNUnet code that generates a directory can reorder the entries in order to better fit the information about files into blocks of 32k. Respecting 32k boundaries where possible makes it easier for gnunet\-directory (and other tools) to recover information from partially downloaded directory files. At the moment, directories can be created by \fBgnunet\-fs\-gtk\fP and \fBgnunet\-publish\fP. Just like ordinary files, a directory can be published in a namespace. GNUnet directories use the (unregistered) mimetype \fBapplication/gnunet\-directory\fP. They can show up among normal search results. The directory file can be downloaded to disk by \fBgnunet\-download\fP(1) for later processing or be handled more directly by \fBgnunet\-fs\-gtk\fP(1). .SH "REPORTING BUGS" Report bugs by using mantis or by sending electronic mail to .SH "SEE ALSO" \fBgnunet\-fs\-gtk\fP(1), \fBgnunet\-publish\fP(1), \fBgnunet\-search\fP(1), \fBgnunet\-download\fP(1) gnunet-0.10.1/doc/man/gnunet-auto-share.10000644000175000017500000001145512225232702014765 00000000000000.TH GNUNET\-AUTO\-SHARE "1" "18 Jun 2012" "GNUnet" .SH NAME gnunet\-auto\-share \- a command line tool to automatically share an entire directory with other users .SH SYNOPSIS .B gnunet\-auto\-share [\fIOPTIONS\fR] DIRNAME .SH DESCRIPTION .PP In order to share files with other GNUnet users, the files must first be made available to GNUnet. This tool can be used to automatically share all files from a certain directory. The program will periodically scan the directory for changes and publish files that are new or that changed on GNUnet. Which files have already been shared is remembered in a ".auto-share" file in the shared directory. You can run the tool by hand or automatically by adding the respective options to your configuration. gnunet\-auto\-share has many options in common with gnunet\-publish, but can only be used to index files. .PP You can use automatic meta\-data extraction (based on libextractor). .PP \fB\-c \fIFILENAME\fR, \fB\-\-config=FILENAME\fR Use alternate config file (if this option is not specified, the default is ~/.config/gnunet.conf). .TP \fB\-D\fR, \fB\-\-disable\-extractor\fR Disable use of GNU libextractor for finding additional keywords and metadata. .TP \fB\-h\fR, \fB\-\-help\fR Print a brief help page with all the options. .TP \fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=\fILOGLEVEL\fR Change the loglevel. Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG. .TP \fB\-p \fIPRIORITY\fR, \fB\-\-prio=\fIPRIORITY\fR Executive summary: You probably don't need it. Set the priority of the published content (default: 365). If the local database is full, GNUnet will discard the content with the lowest ranking. Note that ranks change over time depending on popularity. The default should be high enough to preserve the locally published content in favor of content that migrates from other peers. .TP \fB\-r \fILEVEL\fR, \fB\-\-replication=\fILEVEL\fR Set the desired replication level. If CONTENT_PUSHING is set to YES, GNUnet will push each block (for the file) LEVEL times to other peers before doing normal "random" replication of all content. This option can be used to push some content out into the network harder. Note that pushing content LEVEL times into the network does not guarantee that there will actually be LEVEL replicas. .TP \fB\-v\fR, \fB\-\-version\fR Print the version number. .TP \fB\-V\fR, \fB\-\-verbose\fR Be verbose. Using this option causes gnunet\-publish to print progress information and at the end the file identification that can be used to download the file from GNUnet. .SH SETTING ANONYMITY LEVEL The \fB\-a\fR option can be used to specify additional anonymity constraints. If set to 0, GNUnet will publish the file non-anonymously and in fact sign the advertisement for the file using your peer's private key. This will allow other users to download the file as fast as possible, including using non-anonymous methods (DHT, direct transfer). If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity). However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time infer data about your identity. You can gain better privacy by specifying a higher level of anonymity, which increases the amount of cover traffic your own traffic will get, at the expense of performance. Note that regardless of the anonymity level you choose, peers that cache content in the network always use anonymity level 1. The definition of the ANONYMITY LEVEL is the following. 0 means no anonymity is required. Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the local user, leaving 'v-1' bytes of cover traffic per byte on the wire.

Hint: when recursively downloading a directory, append a '/' to the end of the FILENAME to create a directory of that name. If no FILENAME is specified, gnunet\-download constructs a temporary ID from the URI of the file. The final filename is constructed based on meta\-data extracted using libextractor (if available). .TP \fB\-p \fIDOWNLOADS\fR, \fB\-\-parallelism=DOWNLOADS\fR set the maximum number of parallel downloads that is allowed. More parallel downloads can, to some extent, improve the overall time to download content. However, parallel downloads also take more memory (see also option \-r which can be used to limit memory utilization) and more sockets. This option is used to limit the number of files that are downloaded in parallel (\-r can be used to limit the number of blocks that are concurrently requested). As a result, the value only matters for recursive downloads. The default value is 32. .TP \fB\-r \fIREQUESTS\fR, \fB\-\-request-parallelism=REQUESTS\fR set the maximum number of parallel requests that is allowed. If multiple files are downloaded, gnunet\-download will not run them in parallel if this would cause the number of pending requests to possibly exceed the given value. This is useful since, for example, downloading dozens of multi\-gigabyte files in parallel could exhaust memory resources and would hardly improve performance. Note that the limit only applies to this specific process and that other download activities by other processes are not included in this limit. Consider raising this limit for large recursive downloads with many large files if memory and network bandwidth are not fully utilized and if the parallelism limit (\-p option) is not reached. This option also only matters for recursive downloads. The default value is 4092. .TP \fB\-R\fR, \fB\-\-recursive\fR download directories recursively (and in parallel); note that the URI must belong to a GNUnet directory and that the filename given must end with a '/' \-\- otherwise, only the file corresponding to the URI will be downloaded. Note that in addition to using '\-R', you must also specify a filename ending in '.gnd' so that the code realizes that the top-level file is a directory (since we have no meta data). .TP \fB\-v\fR, \fB\-\-version\fR print the version number .TP \fB\-V\fR, \fB\-\-verbose\fR print progress information .SH NOTES The GNUNET_URI is typically obtained from gnunet\-search. gnunet\-fs\-gtk can also be used instead of gnunet\-download. If you ever have to abort a download, you can at any time continue it by re\-issuing gnunet\-download with the same filename. In that case GNUnet will not download blocks again that are already present. GNUnet's file\-encoding will ensure file integrity, even if the existing file was not downloaded from GNUnet in the first place. Temporary information will be appended to the target file until the download is completed. .SH SETTING ANONYMITY LEVEL The \fB\-a\fR option can be used to specify additional anonymity constraints. If set to 0, GNUnet will try to download the file as fast as possible, including using non-anonymous methods. If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity). However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time infer data about your identity. You can gain better privacy by specifying a higher level of anonymity, which increases the amount of cover traffic your own traffic will get, at the expense of performance. Note that your download performance is not only determined by your own anonymity level, but also by the anonymity level of the peers publishing the file. So even if you download with anonymity level 0, the peers publishing the data might be sharing with a higher anonymity level, which in this case will determine performance. Also, peers that cache content in the network always use anonymity level 1. This option can be used to limit requests further than that. In particular, you can require GNUnet to receive certain amounts of traffic from other peers before sending your queries. This way, you can gain very high levels of anonymity \- at the expense of much more traffic and much higher latency. So set it only if you really believe you need it. The definition of ANONYMITY\-RECEIVE is the following. 0 means no anonymity is required. Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the local user, leaving 'v-1' bytes of cover traffic per byte on the wire. Thus, if GNUnet routes n bytes of messages from foreign peers (using anonymous routing), it may originate n/(v-1) bytes of queries in the same time\-period. The time\-period is twice the average delay that GNUnet defers forwarded queries. The default is 1 and this should be fine for most users. Also notice that if you choose very large values, you may end up having no throughput at all, especially if many of your fellow GNUnet\-peers all do the same. .SH FILES .TP ~/.config/gnunet.conf GNUnet configuration file .SH "REPORTING BUGS" Report bugs to or by sending electronic mail to .SH "SEE ALSO" \fBgnunet\-fs\-gtk\fP(1), \fBgnunet\-publish\fP(1), \fBgnunet\-search\fP(1), \fBgnunet.conf\fP(5), \fBgnunet\-service\-fs\fP(1) gnunet-0.10.1/doc/man/gnunet-conversation.10000644000175000017500000000270212225232703015423 00000000000000.TH GNUNET\-CONVERSATION 1 "Oct 5, 2013" "GNUnet" .SH NAME gnunet\-conversation \- have a conversation with your peers .SH SYNOPSIS .B gnunet\-conversation \-e NAME [OPTIONS] .RI URI .br .SH DESCRIPTION \fBgnunet\-conversation\fP can be used to have a conversation with other GNUnet users.

A client can issue one of two messages to its service: .TS tab (@); l lx. 1@T{ A request to compute a vectorproduct with another peer (\fBAlice\fP) T} 2@T{ Elements to support a peer in computing a vectorproduct (\fBBob\fP) T} .TE Both requests must share the same SID, which can be an arbitrary string identifying the session. SIDs should be unique, however it is sufficient to guarantee the uniqueness of the tupel element count and session ID. \fBAlice\fP\'s client must supply the ASCII encoded peer ID of bob\'s service, it will internally be checked by the client for validity. Invalid values here result in the client or the service failing the session. Elements are handed over as signed decimal integers, the element count supplied by \fBAlice\fP and \fBBob\fP must match. \fBAlice\fP can also supply a mask for these values to her service, which allows partial vector products to be computed across the vector. Elements can be masked by setting their the corresponding mask element to zero, any other value means the element will not be masked. \fBAlice\fP\'s client will also mask all 0-values to avoid information leakage to \fBBob\fP. The protocol by definition relies on \fBAlice\fP and \fBBob\fP being benign, thus \fBBob\fP can arbitrarily falsify his information. Both peers collaborate to achieve a correct result. .SH OPTIONS .B .IP "\-e ELEMENTS, \-\-elements=ELEMENTS" The element-vector the vectorproduct should be computed over in signed decimal form, eg: \"42,1,-3,3,7\". Zero value elements will be automatically masked. .B .IP "\-m MASK, \-\-mask=MASK" Elements in the vector can be masked. There must be at least two elements left in the vector to compute a vectorproduct. Non-Zero values indicate an element is not maskes. .B .IP "\-k KEY, \-\-key=KEY" The session key, a shared string of arbitrary length from which the SID will be generated .B .IP "\-c FILENAME, \-\-config=FILENAME" Use the configuration file FILENAME. .B .IP "\-p PEERID, \-\-peer=PEERID" The remote peer\'s ASCII-armored gnunet-peer ID as output by gnunet-peerinfo. If this option is not given, the peer will take the \fBBob\fP\'s role. .B .IP "\-h, \-\-help" Print short help on options. .B .IP "\-L LOGLEVEL, \-\-loglevel=LOGLEVEL" Use LOGLEVEL for logging. Valid values are DEBUG, INFO, WARNING and ERROR. .B .IP "\-v, \-\-version" Print GNUnet version number. .SH BUGS Report bugs by using Mantis or by sending electronic mail to .SH SEE ALSO

The default location for the configuration file for the services is "~gnunet/.config/gnunet.conf"; however, as normal users also may need read-access to this configuration, you might want to instead put the service process configuration in "/etc/gnunet.conf". gnunet\-setup (part of the GTK package) can be used to edit this configuration. The parts of GNUnet that is ran as a normal user may have config options too and they read from "$HOME/.config/gnunet.conf". The latter config file can skip any options for the services. .TP The basic structure of the configuration file is the following. The file is split into sections. Every section begins with "[SECTIONNAME]" and contains a number of options of the form "OPTION=VALUE". Empty lines and lines beginning with a "#" are treated as comments. Almost all options are optional and the tools resort to reasonable defaults if they are not present. .PP Default values for all of the options can be found in the files in the "$GNUNET_PREFIX/share/gnunet/config.d/" directory. A typical setup will work out of the box with those. See the examples section below for some common setups on top of that. .SH General OPTIONS .PP Many options will be common between sections. They can be repeated under each section with different values. The "[PATHS]" section is special. Here, it is possible to specify values for variables like "GNUNET_HOME". Then, in all filenames that begin with "$GNUNET_HOME" the "$GNUNET_HOME" will be replaced with the respective value at runtime. The main use of this is to redefine "$GNUNET_HOME", which by default points to "$HOME/.config/". By setting this variable, you can change the location where GNUnet stores its internal data. .PP The following options are generic and shared by all services: .IP HOSTNAME The hostname specifies the machine on which the service is running. This is usually "localhost". .IP BINARY The filename that implements the service. For example "gnunet-service-ats". .IP AUTOSTART This defines the section it is defined in, which should be a service, will be started by the ARM service if the value is set to YES. .IP ACCEPT_FROM A semi-column separated list of IPv4 addresses that are allowed to use the service; usually 127.0.0.1. .IP ACCEPT_FROM6 A semi-column separated list of IPv6 addresses that are allowed to use the service; usually ::1. .IP UNIXPATH Path to use for the UNIX domain socket for inter process communication with the service on POSIX systems. .IP UNIX_MATCH_UID If UNIX domain sockets are used, set this to YES if only users with the same UID are allowed to access the service. .IP UNIX_MATCH_GID If UNIX domain sockets are used, set this to YES if only users with the same GID are allowed to access the service. .IP USER_SERVICE Set to YES if this service should be run per-user, NO if this is a system service. End-users should never have to change the defaults GNUnet provides for this option. .SH ARM Options This section is configuration for the automatic restart manager which is responsible for launching services. .IP DEFAULTSERVICES list of services that ARM should always start by default. AUTOSTART services are only started when the service is needed by some other service. The services listed here will always be started, not just on-demand. "topology" and "hostlist" should virtually always be listed here, and most users will want to specify high-level applications like "fs", "gns" or "pt" here as well. .B .SH ATS Options .IP UNSPECIFIED_QUOTA_IN quotes in KiB or MiB per seconds.

Upon successful revocation, all peers will be informed about the invalidity of the key. As this is an expensive operation, GNUnet requires the issuer of the revocation to perform an expensive proof-of-work computation before he will be allowed to perform the revocation. gnunet\-revocation will perform this computation. The computation can be performed ahead of time, with the resulting revocation certificate being stored in a file for later "instant" use. gnunet\-revocation also makes is possible to resume the pre-calculation of a revocation --- simply abort a running proof-of-work calculation with CTRL-C, and the existing revocation certificate file will contain the status of the computation. Note that performing a revocation proof-of-work is deliberately VERY expensive. Depending on your CPU, the calculation can take days or weeks. .SH OPTIONS .B .IP "\-t KEY, \-\-test=KEY" Check if the given KEY (ASCII\-encoded public key required) has been revoked. .B .IP "\-R NAME, \-\-revoke=NAME" Calculate or perform revocation for the ego with the given NAME. .B .IP "\-p, \-\-perform" Actually perform the revocation as soon as possible (do not just generate a revocation certificate, use it).

Names are made available on a First Come First Served basis (hence fcfs). Registered names do not expire. The HTTP server is run on the port that is specified in the configuration file in section "[fcfsd]" under the name "HTTPPORT". The key of the zone in which the names are registered must be specified under the name "ZONEKEY" in the same section. It is possible to manage gnunet\-gns\-fcfsd using gnunet\-(service\-arm) by starting the daemon using "gnunet\-arm \-i fcfsd" or by adding "fcfds" to the "DEFAULTSERVICES" option. An FCFS\-zone is run at http://gnunet.org/fcfs/. The respective zone key can be imported into an individual user's zone using "gnunet-gns-import.sh". GNS users are encouraged to register their zone with the gnunet.org FCFS authority. If you want to run your own FCFS registrar, you need to first create a pseudonym (using "gnunet\-identity \-C NAME"), and then assign it to be used for the "fcfsd" service using "gnunet\-identity \-e NAME \-s fcfsd".

A DNS\-to\-GNS proxy using gnunet\-dns2gns is available at ".zkey.eu" If you do not want to specify a public key and are the owner of the zone that gnunet\-dns2gns will use for GNS lookups, you need to first create a pseudonym (using "gnunet\-identity \-C NAME"), and then assign it to be used for the "dns2gns" service using "gnunet\-identity \-e NAME \-s dns2gns".

In fact, distributions are encouraged to consider not shipping it at all. Running gnunet\-nat\-server's is similar to running hostlist servers: it is a special service to the community with special requirements and no benefit to those running the service. This program will listen on the specified PORT for incoming requests to test a peer's network connectivity. Incoming requests can ask it to connect to a given IPv4 address (and port) using TCP or UDP and to send a 2-byte test message using the specified address. The program can also be asked to send a "fake" ICMP response message to a given IPv4 address (for autonomous NAT traversal \-\-\- see the description in the respective research paper). The idea is that gnunet\-nat\-server will be run on some trusted hosts with unrestricted connectivity to allow GNUnet users to test their network configuration. As written, the code allows any user on the Internet to cause the gnunet\-nat\-server to send 2-bytes of arbitrary data to any TCP or UDP port at any address. We believe that this is generally harmless. When running gnunet\-nat\-server, make sure to use a configuration that disables most NAT options but enables 'enable_nat_client' and sets 'internal_address' to the global IP address of your local host. Also, the gnunet\-helper\-nat\-client should be installed locally and run with root privileges (SUID), otherwise the gnunet\-nat\-server will not work properly. Note that gnunet\-nat\-server could be run via gnunet\-arm but typically is not. Also, the name of the host and port that gnunet\-nat\-server is run on should be specified in the NATSERVER option in the [setup] section of the configuration file of hosts that are supposed to autoconfigure with this server. .SH OPTIONS .B .IP "\-c FILENAME, \-\-config=FILENAME" Use the configuration file FILENAME. .SH BUGS Report bugs by using Mantis or by sending electronic mail to .SH SEE ALSO gnunet\-transport(1) gnunet-0.10.1/doc/man/gnunet-arm.10000644000175000017500000000411012225232702013462 00000000000000.TH GNUNET\-ARM 1 "Jan 4, 2012" "GNUnet" .SH NAME gnunet\-arm \- control GNUnet services .SH SYNOPSIS .B gnunet\-arm .RI [ options ] .br .SH DESCRIPTION \fBgnunet\-arm\fP can be used to start or stop GNUnet services, including the ARM service itself.

GNUnet does not automatically share all files from a certain directory (however, you can do this with the gnunet\-auto\-share tool). In fact, even files that are downloaded are not automatically shared. .PP In order to start sharing files, the files must be added either using gnunet\-publish or a graphical interface such as gnunet\-fs\-gtk. The command line tool gnunet\-publish is more useful if many files are supposed to be added. gnunet\-publish can automatically publish batches of files, recursively publish directories, create directories that can be browsed within GNUnet and publish file lists in a namespace. When run on a directory, gnunet\-publish will always recursively publish all of the files in the directory. .PP gnunet\-publish can automatically extract keywords from the files that are shared. Users that want to download files from GNUnet use keywords to search for the appropriate content. You can disable keyword extraction with the \-D option. You can manually add keywords using the \-k option. The keywords are case\-sensitive. .PP In addition to searching for files by keyword, GNUnet allows organizing files into directories. With directories, the user only needs to find the directory in order to be able to download any of the files listed in the directory. Directories can contain pointers to other directories. .PP With gnunet\-publish, it is easy to create new directories simultaneously when adding the files. Simply pass the name of a directory instead of a file. .PP Since keywords can be spammed (any user can add any content under any keyword), GNUnet supports namespaces. A namespace is a subset of the searchspace into which only the holder of a certain pseudonym can add content. Any GNUnet user can create any number of pseudonyms using \fBgnunet\-pseudonym\fR. Pseudonyms are stored in the user's GNUnet directory. While pseudonyms are locally identified with an arbitrary string that the user selects when the pseudonym is created, the namespace is globally known only under the hash of the public key of the pseudonym. Since only the owner of the pseudonym can add content to the namespace, it is impossible for other users to pollute the namespace. gnunet\-publish automatically publishes the top\-directory (or the only file if only one file is specified) into the namespace if a pseudonym is specified. .PP It is possible to update content in GNUnet if that content was placed and obtained from a particular namespace. Updates are only possible for content in namespaces since this is the only way to assure that a malicious party can not supply counterfeited updates. Note that an update with GNUnet does not make the old content unavailable, GNUnet merely allows the publisher to point users to more recent versions. You can use the \-N option to specify the future identifier of an update. When using this option, a GNUnet client that finds the current (\-t) identifier will automatically begin a search for the update (\-N) identifier. If you later publish an update under the (\-N) identifier, both results will be given to the user. .PP You can use automatic meta\-data extraction (based on libextractor) or the command\-line option \-m to specify meta-data. For the \-m option you need to use the form keyword\-type:value. For example, use "\-m os:Linux" to specify that the operating system is Linux. Common meta\-data types are "author", "title" , "mimetype", "filename", "language", "subject" and "keywords". A full list can be obtained from the extract tool using the option \-\-list. The meta\-data is used to help users in searching for files on the network. The keywords are case\-sensitive. .PP GNUnet supports two styles of publishing files on the network. Publishing a file means that a copy of the file is made in the local (!) database of the node. Indexing a file means that an index is added to the local (!) database with symbolic links to the file itself. The links will use the SHA-512 hash of the entire file as the filename. Indexing is generally significantly more efficient and the default choice. However, indexing only works if the indexed file can be read (using the same absolute path) by gnunet-service-fs. If this is not the case, indexing will fail (and gnunet\-publish will automatically revert to publishing instead). Regardless of which method is used to publish the file, the file will be slowly (depending on how often it is requested and on how much bandwidth is available) dispersed into the network. If you publish or index a file and then leave the network, it will almost always NOT be available anymore. \fB\-c \fIFILENAME\fR, \fB\-\-config=FILENAME\fR Use alternate config file (if this option is not specified, the default is ~/.config/gnunet.conf). .TP \fB\-D\fR, \fB\-\-disable\-extractor\fR Disable use of GNU libextractor for finding additional keywords and metadata. .TP \fB\-e\fR, \fB\-\-extract\fR Print the list of keywords that will be used for each file given the current options. Do not perform any indexing or publishing. .TP \fB\-h\fR, \fB\-\-help\fR Print a brief help page with all the options. .TP \fB\-k \fIKEYWORD\fR, \fB\-\-key=KEYWORD\fR additional key to index the content with (to add multiple keys, specify multiple times). Each additional key is case\-sensitive. Can be specified multiple times. The keyword is only applied to the top\-level file or directory. .TP \fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=\fILOGLEVEL\fR Change the loglevel. Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG. .TP \fB\-m \fITYPE:VALUE\fR, \fB\-\-meta=\fITYPE:VALUE\fR For the main file (or directory), set the metadata of the given TYPE to the given VALUE. Note that this will not add the respective VALUE to the set of keywords under which the file can be found. .TP \fB\-n\fR, \fB\-\-noindex\fR Executive summary: You probably don't need it. Do not index, full publishing. Note that directories, RBlocks, SBlocks and IBlocks are always published (even without this option). With this option, every block of the actual files is stored in encrypted form in the block database of the local peer. While this adds security if the local node is compromised (the adversary snags your machine), it is significantly less efficient compared to on\-demand encryption and is definitely not recommended for large files. .TP \fB\-N \fIID\fR, \fB\-\-next=\fIID\fR Specifies the next ID of a future version of the SBlock. This option is only valid together with the \-P option. This option can be used to specify what the identifier of an updated version will look like. Note that specifying \-i and \-N without \-t is not allowed. .TP \fB\-p \fIPRIORITY\fR, \fB\-\-prio=\fIPRIORITY\fR Executive summary: You probably don't need it. Set the priority of the published content (default: 365). If the local database is full, GNUnet will discard the content with the lowest ranking. Note that ranks change over time depending on popularity. The default should be high enough to preserve the locally published content in favor of content that migrates from other peers. .TP \fB\-P \fINAME\fR, \fB\-\-pseudonym=\fINAME\fR For the top\-level directory or file, create an SBlock that places the file into the namespace specified by the pseudonym NAME. .TP \fB\-r \fILEVEL\fR, \fB\-\-replication=\fILEVEL\fR Set the desired replication level. If CONTENT_PUSHING is set to YES, GNUnet will push each block (for the file) LEVEL times to other peers before doing normal "random" replication of all content. This option can be used to push some content out into the network harder. Note that pushing content LEVEL times into the network does not guarantee that there will actually be LEVEL replicas. .TP \fB\-s\fR, \fB\-\-simulate-only\fR When this option is used, gnunet\-publish will not actually publish the file but just simulate what would be done. This can be used to compute the GNUnet URI for a file without actually sharing it. .TP \fB\-t \fIID\fR, \fB\-\-this=\fIID\fR Specifies the ID of the SBlock. This option is only valid together with the\ \-s option. .TP \fB\-u \fIURI\fR, \fB\-\-uri=\fIURI\fR This option can be used to specify the URI of a file instead of a filename (this is the only case where the otherwise mandatory filename argument must be omitted). Instead of publishing a file or directory and using the corresponding URI, gnunet\-publish will use this URI and perform the selected namespace or keyword operations. This can be used to add additional keywords to a file that has already been shared or to add files to a namespace for which the URI is known but the content is not locally available. .TP \fB\-v\fR, \fB\-\-version\fR Print the version number. .TP \fB\-V\fR, \fB\-\-verbose\fR Be verbose. Using this option causes gnunet\-publish to print progress information and at the end the file identification that can be used to download the file from GNUnet. .SH SETTING ANONYMITY LEVEL The \fB\-a\fR option can be used to specify additional anonymity constraints. If set to 0, GNUnet will publish the file non-anonymously and in fact sign the advertisement for the file using your peer's private key. This will allow other users to download the file as fast as possible, including using non-anonymous methods (DHT, direct transfer). If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity). However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time infer data about your identity. You can gain better privacy by specifying a higher level of anonymity, which increases the amount of cover traffic your own traffic will get, at the expense of performance. Note that regardless of the anonymity level you choose, peers that cache content in the network always use anonymity level 1. The definition of the ANONYMITY LEVEL is the following. 0 means no anonymity is required. Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the local user, leaving 'v-1' bytes of cover traffic per byte on the wire. Thus, if GNUnet routes n bytes of messages from foreign peers (using anonymous routing), it may originate n/(v-1) bytes of data in the same time\-period. The time\-period is twice the average delay that GNUnet defers forwarded queries. The default is 1 and this should be fine for most users. Also notice that if you choose very large values, you may end up having no throughput at all, especially if many of your fellow GNUnet\-peers all do the same. .SH EXAMPLES .PP \fBBasic examples\fR Index a file COPYING: # gnunet\-publish COPYING Publish a file COPYING: # gnunet\-publish \-n COPYING Index a file COPYING with the keywords \fBgpl\fR and \fBtest\fR: # gnunet\-publish \-k gpl \-k test COPYING Index a file COPYING with description "GNU License", mime-type "text/plain" and keywords \fBgpl\fR and \fBtest\fR: # gnunet\-publish \-m "description:GNU License" \-k gpl \-k test \-m "mimetype:text/plain" COPYING \fBUsing directories\fR Index the files COPYING and AUTHORS with keyword \fBtest\fR and build a directory containing the two files. Make the directory itself available under keyword \fBgnu\fR and disable keyword extraction using libextractor: # mkdir gnu # mv COPYING AUTHORS gnu/ # gnunet\-publish \-K test \-k gnu \-D gnu/ Neatly publish an image gallery in \fBkittendir/\fR and its subdirs with keyword \fBkittens\fR for the directory but no keywords for the individual files or subdirs (\-n).

Publish the top\-level directory into the namespace under the pseudonym RIAA-2 (\-P) under identifier 'MUSIC' (\-t) and promise to provide an update with identifier 'VIDEOS' (\-N): # gnunet\-publish \-P RIAA-2 \-t MUSIC \-N VIDEOS /home/ogg Recursively publish (\-n) /var/lib/mysql and build a matching directory structure, but disable the use of libextractor to extract keywords (\-n). Print the file identifiers (\-V) that can be used to retrieve the files. This will store a copy of the MySQL database in GNUnet but without adding any keywords to search for it. Thus only people that have been told the secret file identifiers printed with the \-V option can retrieve the (secret?) files: # gnunet\-publish \-nV /var/lib/mysql Create a namespace entry 'root' in namespace MPAA-1 and announce that the next update will be called 'next': # gnunet\-publish \-P MPAA-1 \-t root \-N next noise.mp3 Update the previous entry, do not allow any future updates: # gnunet\-publish \-P MPAA-1 \-t next noise_updated.mp3 .SH FILES .TP ~/.config/gnunet.conf GNUnet configuration file .SH "REPORTING BUGS" Report bugs to or by sending electronic mail to .SH "SEE ALSO" \fBgnunet\-auto\-share\fP(1), \fBgnunet\-fs\-gtk\fP(1), \fBgnunet\-search\fP(1), \fBgnunet\-download\fP(1), \fBgnunet.conf\fP(5), \fBextract\fP(1) gnunet-0.10.1/doc/man/gnunet-transport.10000644000175000017500000000500412225232703014743 00000000000000.TH gnunet\-transport "1" "26 Oct 2011" "GNUnet" .SH NAME gnunet\-transport \- measure and control the transport subsystem .SH SYNOPSIS .B gnunet\-transport [\fIOPTIONS\fR] .SH DESCRIPTION .PP gnunet\-transport is a tool to access various functions of GNUnet's transport subsystem from the command\-line. Most of these are not expected to be useful for end-users. gnunet\-transport can be used to evaluate the performance of the transports, force a peer to connect to another peer (if possible). Other functions should be added in the near future. .TP \fB\-b\fR, \fB\-\-benchmark\fR measure how fast we are receiving data (from all connections). On exit, the data rate will be reported. Runs until aborted with CTRL-C. .TP \fB\-C \fIPEER\fR, \fB\-\-connect=PEER\fR peer to connect to (used in conjunction with \-p) .TP \fB\-c \fIFILENAME\fR, \fB\-\-config=FILENAME\fR configuration file to use .TP \fB\-e \fB\-\-events\fR provide information about all connect and disconnect events (continuously) .TP \fB\-h\fR, \fB\-\-help\fR print help page .TP \fB\-i\fR, \fB\-\-information\fR print information about our current connections (once) .TP \fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=LOGLEVEL\fR Change the loglevel. Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG. .TP \fB\-l \fILOGFILE\fR, \fB\-\-logfile=LOGFILE\fR configure logging to write logs to LOGFILE .TP \fB\-m\fR, \fB\-\-monitor\fR print information about our current connections (continuously) .TP \fB\-p \fIPEER\fR, \fB\-\-peer=PEER\fR the peer identity .TP \fB\-s\fR, \fB\-\-send\fR transmit (dummy) traffic as quickly as possible to the peer specified with the \-p option. The rate will still be limited by the quota(s) determined by the peers (ATS subsystem). Will run until CTRL\-C is pressed or until the connection to the other peer is disrupted. .TP \fB\-t\fR, \fB\-\-test\fR test transport configuration. With this flag, the tool will check if each of the configured transport plugins has a working address. Plugins that do not have a listen port configured will be ignored. The test is performed with the help of an external server (by default running on gnunet.org) which tries to contact the local machine. The test can only work if the local GNUnet peer is not yet running. .TP \fB\-v\fR, \fB\-\-version\fR print the version number .TP \fB\-V\fR, \fB\-\-verbose\fR be verbose .SH NOTES .SH "REPORTING BUGS" Report bugs by using mantis or by sending electronic mail to .SH "SEE ALSO" \fBgnunet\-arm\fP(1) gnunet-0.10.1/doc/man/gnunet-vpn.10000644000175000017500000000526212225232703013520 00000000000000.TH GNUNET\-VPN 1 "25 Feb 2012" "GNUnet" .SH NAME gnunet\-vpn \- manually setup a GNUnet VPN tunnel .SH SYNOPSIS .B gnunet\-vpn .RI [ options ] .br .SH DESCRIPTION \fBgnunet\-vpn\fP can be used to manually setup a VPN tunnel via the GNUnet network. There are two main types of tunnels. Tunnels to an exit node which routes the traffic to the global Internet, and tunnels to a node that runs a service only within GNUnet. Depending on the type of tunnel, gnunet\-vpn takes different options. The "\-i" option is required for tunnels to an exit node, whereas the "\-p" and "\-s" options in conjunction with either "\-u" or "\-t" are required for tunnels to services. For exit tunnels, both UDP and TCP traffic will be redirected. For service tunnels, either UDP ("\-u") or TCP ("\-t") traffic will be redirected. The tool will display the IP address for this end of the tunnel. The address can be displayed as soon as it has been allocated, or only after ("\-a") the tunnel has been created. .SH OPTIONS .B .IP "\-4, \-\-ipv4" Desired IP address on this end of the tunnel should be an IPv4 address. .B .IP "\-6, \-\-ipv6" Desired IP address on this end of the tunnel should be an IPv6 address. .B .IP "\-c FILENAME, \-\-config=FILENAME" Use the configuration file FILENAME. .B .IP "\-d TIME, \-\-duration TIME" The mapping should be established for TIME. The value given must be a number followed by a space and a time unit, for example "500 ms". Note that the quotes are required on the shell. Default is 5 minutes. .B .IP "\-h, \-\-help" Print short help on options. .B .IP "\-i IP, \-\-ip IP" Tunnel should be to an exit node and connect to the given IPv4 or IPv6 IP address. Note that you can specify an IPv6 address as the target here, even in combination with "\-4" (4to6) and similarly you can specify an IPv4 address in combination with "\-6" (6to4). .B .IP "\-L LOGLEVEL, \-\-loglevel=LOGLEVEL" Use LOGLEVEL for logging. Valid values are DEBUG, INFO, WARNING and ERROR. .B .IP "\-p PEERID, \-\-peer=PEERID" Name of the peer offering the service to connect to. Cannot be used in conjunction with "\-i", requires "\-s". .B .IP "\-s NAME, \-\-service=NAME" Name of the service running on the target peer. Cannot be used in conjunction with "\-i", requires "\-p". .B .IP "\-t, \-\-tcp" Service runs TCP. Either "\-t" or "\-u" must be specified when using "\-s". .B .IP "\-u, \-\-udp" Service runs UDP. Either "\-t" or "\-u" must be specified when using "\-s". .B .IP "\-V, \-\-verbose" Be verbose. .B .IP "\-v, \-\-version" Print GNUnet version number. .SH BUGS Report bugs by using Mantis or by

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. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command `./configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. gnunet-0.10.1/config.rpath0000755000175000017500000003744411374167231012343 00000000000000#! /bin/sh # Output a system dependent set of variables, describing how to set the # run time search path of shared libraries in an executable. # # Copyright 1996-2006 Free Software Foundation, Inc. # Taken from GNU libtool, 2001 # Originally by Gordon Matzigkeit , 1996 # # This file is free software; the Free Software Foundation gives # unlimited permission to copy and/or distribute it, with or without # modifications, as long as this notice is preserved. # # The first argument passed to this file is the canonical host specification, # CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM # or # CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM # The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld # should be set by the caller. # # The set of defined variables is at the end of this script. # Known limitations: # - On IRIX 6.5 with CC="cc", the run time search patch must not be longer # than 256 bytes, otherwise the compiler driver will dump core.

Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. 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. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS 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 state 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) 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 3 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, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program 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, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU 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 Lesser General Public License instead of this License.

See if it doesn't break anything for you. Arm service is started with -c only when the process that runs arm service has "[arm]/CONFIG" defined in the configuration used to run arm service (usually - process' own configuration). Since default [arm] config has no CONFIG defined anymore (thanks to your r25908), we need to add this code to put the config file that was passed to gnunet-arm tool via -c as "[arm]/CONFIG" for arm service to receive it. Otherwise arm service is run without config and reads default config (~/.gnunet/gnunet.conf) instead, which is clearly not what we need. 2013-01-25 22:27 harsha * [r25918] po/POTFILES.in: fix 2746
