+*************************************** + +Free software is going international! 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%. + + Ready PO files af am ar

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. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`translation@iro.umontreal.ca' to make the `.pot' files available to +the translation teams. + diff --git a/AUTHORS b/AUTHORS new file mode 100644 index 000000000..950320941 --- /dev/null +++ b/AUTHORS @@ -0,0 +1,85 @@ +Primary developers (0.9.x series): +Christian Grothoff +Heikki Lindholm +Nils Durner +Milan Bouchet-Valat + +Code contributions also came from: +Adam Warrington [ UPnP ] +Alex Harper [ OS X CPU load ] +Andrew McDonald [ SHA-512] +Antti Salonen +Blake Matheny +Clytie Siddall +David Kuehling +Enrico Scholz +Eric Haumant +Eric Noack +Felix von Leitner [ diet libc snprintf for win32 ] +Gerd Knorr +Glenn McGrath +Hendrik Pagenhardt +Heikki Lindholm +Igor Wronsky +Ioana Patrascu + +Jake Dust +James Blackwell +Jean-Luc Cooke [ SHA-512] +Jussi Eloranta +Jürgen Appel +Kevin Vandersloot [original code of gnome-system-monitor] +Krista Bennett Grothoff +Kyle McMartin [ SHA-512] +Larry Waldo +Ludovic Courtès +Marko Räihä +Michael John Wensley +Nathan Evans +Paul Ruth +Renaldo Ferreira +Risto Saarelma +Roman Zippel +Romain Lievin +sheda +Simo Viitanen +Tiberius Stef +Tomi Tukiainen +Tuomas Toivonen +Tzvetan Horozov +Uli Luckas +Vasil Dimov +Werner Koch [original code of libgcrypt] + +Translations (webpage, documentation, as far as known): +Chinese : Di Ma +Danish : Jens Palsberg +Deutsch : Christian Grothoff , + Nils Durner +French : Mathieu , + Eric Haumant + Milan +Japanese : Hiroshi Yamauchi +Polish : Adam Welc +Romaneste : Bogdan Carbunar +Kinyarwanda: Steven Michael Murphy +Vietnamese : Phan Vinh Thinh and Clytie Siddall +Swedish : Daniel Nylander +Spanish : Miguel Angel Arruga Vivas +Turkish : Nilgün Belma Bugüner + +Logos: +GNU in Net : Christian Muellner +GNU with Net : Christian Muellner +AFS Face : Alex Jones +new GNU in Net: Nicklas Larsson + +Maintainers: +FreeBSD : Kirill Ponomarew +Debian GNU/Linux: Daniel Baumann and + Arnaud Kyheng +OS X : Jussi Eloranta + + +If you have contributed and are not listed here, please +notify one of the maintainers in order to be added. diff --git a/COPYING b/COPYING new file mode 100644 index 000000000..94a9ed024 --- /dev/null +++ b/COPYING @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + 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.

Releasing GNUnet 0.6.2. + +Mon Apr 26 21:13:45 EST 2004 + Added support to gnunet-check to convert file index database + to new design.

Various memory leaks + from gnunetd to gnunet-download, problems + with bloomfilters and gnunet-check, enforcing + storage limitations set by the user, fixes + in the UDP, TCP and SMTP transports; + better thread termination (avoid asynchronous + cancellation). Not to mention the new + tools gnunet-transport-check and gnunet-tbench + for the evaulation of correctness and performance + of the transport services. + +Wed Nov 6 22:49:24 EST 2002 + Added load smoothing for network and CPU load + such that we quickly adapt to increasing load, + but slowly reduce the (effective) load value + used in the policy if the load drops. This should + help avoiding 0-1 policies where we always jump + up and down between 100% load and no load, letting + in one period all traffic through and in the next + none. + +Wed Nov 6 00:31:39 EST 2002 + Added port==0 for UDP and TCP transport as an + option to indicate that the transport is to be + used only to establish connections to other + peers but not as a server-socket (that is, + if the port is 0, other GNUnet peers can not + connect to the local node's UDP or TCP port, + but the local node can still use UDP + (unidirectional) or TCP (even bi-directional) + to talk to other peers. This is useful if a + node is behind a NAT box and can not receive + inbound traffic but is able to send messages to + other peers (and in the case of TCP even receive + messages if the local peer initiated the + bi-directional connection). Currently, a peer + must always provide at least one transport under + which the peer can be "actively" reached since + otherwise other peers will not keep the public + key of that peer and thus not be able to + complete the session key exchange. For NAT-box + peers, SMTP might be a viable choice for that + "active" protocol. + +Fri Oct 11 02:16:42 EST 2002 + Added bloomfilter interface and calls to the BF from + the AFS service implementation. Missing for working + bloomfilter are calls from gnunet-insert to update + the bloom-filter (top-CHK and super-queries) and the + actual bloom-filter implementation. + +Tue Oct 8 20:35:45 EST 2002 + TCP transport now works with only one thread (using + select) instead of one thread per peer-connection. + +Fri Sep 27 02:24:52 EST 2002 + New content encoding (still only 1k blocks, but with + CHK style IBocks and GBlocks for aggressive content + migration) now seems to work. + +Mon Sep 16 01:57:55 EST 2002 + Implemented gnunet-chat, a demo-application for + how to develop p2p applications on top of GNUnet. + +Sun Sep 15 22:48:28 EST 2002 + Fixing (long standing) problem with segfaults under BSD + due to stack overflow in threads. + +Sun Sep 15 02:04:52 EST 2002 + TCP transport layer implementation seems to work now. + gnunet.conf is now documented on the web. HELO exchange + is fixed, so is the CS-connection whitelisting. + +Fri Sep 13 00:51:01 EST 2002 + Update on the progress towards 0.4.9. What is missing? + * new content encoding to facilitate: + - content migration + - discriminated routing (downloads vs. searches) + - variable blocksize (?) + - self-synchronizing stream encoding (?) + * additional transport layers (SMTP, TCP, HTTP) + * demo application (chat) for how to use the API + * documentation on new gnunet.conf + * known bugs: + - Igor reports, HELO exchange is broken + - David reports, CS-connection whitelisting is broken + - rpm.spec is outdated (add GNUnet's dynamic libraries) + + What has been resolved so far: + Major: + * transport and application layer have been abstracted + * dynamic loading of transports and applications is + implemented + * routing much faster since slots are freed earlier + * querymanager is more intelligent in where to send + queries (presumably, not tested) + + Refactoring: + * configuration can store options from commandline + * statistics is totally dynamic and can be extended + * connection buffer does callbacks on applications to + fill buffers with queries instead of noise, and + the querymanager makes use of this + + Moving: + * common/ is gone + * gnettypes.h is gone + * AFS specific code is all in AFS + * renaming is also done + +Sun Aug 25 15:30:56 EST 2002 + Moving work towards 0.4.9 to CVS. The major goals are: + * independent transport layer (UDP, TCP, SMTP, HTTP, + any of these should be possible in the future); also, + the MTU may be defined differently by any one of them. + * independent application layer. Anonymous File Sharing + (AFS) should just be one application for the GNUnet + core. + + Other minor goals and refactorings include: + * configuration - we should be able to update dynamically + options from the gnunet.conf file. E.g. by adding options + from the command line + * statistics - we should not have a hardwired fixed set + of datapoints, the statistics module should be useful + for any kind of statistics + * noise reduction - the connection buffer should allow + the use of intelligent applications that get notified + if noise would be send and then can plug in useful data + + And then there is just moving stuff: + * move "common/" to where it belongs (either applications + or server) + * gnettypes is bad if we want to seperate app specifcs + and core. The typedefs should be placed where they are + used + * database does not belong in util, it's AFS specific + * AFS: cleaner separation between database, encoding, + protocol implementation, shell-tools and GUI code. + + And finally, renaming: + * if we have TCP for peer-to-peer communications, + we can't use "TCP" vs. "UDP" to distinguish p2p from + client-server, thus: "UDP" becomes "p2p" and "TCP" + becomes "CS". At least where they were used to distinguish + node-to-node and client-server (gnunetd). + +Sun Aug 25 15:02:31 EST 2002 + Releasing GNUnet 0.4.6. + +Thu Aug 22 01:31:21 EEST 2002 + gnunet-gtk should now be able to perform multiple + search and download operations simultaneously (atleast a couple). + +Tue Aug 20 23:11:10 EEST 2002 + Fixed segfault in gnunet-search and gnunet-gtk which appeared + when there was lots of results. + Modified gnunetd to return more results at once if there + is excess bandwidth. + +Sun Aug 18 23:57:10 EST 2002 + Reworked the lookup-database. The old database got + into trouble storing data when it was 6% full. Some + simulations show that the new approach should manage + 94% and should be about as fast (more CPU, presumably + slightly fewer random disc accesses). + This change is INCOMPATIBLE with 0.4.5. You *must* + run "gnunet-check -a" before starting this new version + of gnunetd in order to migrate to the new format. For + database simulation and statistical numbers, see + also src/historical/simula.c. + +Fri Aug 16 17:07:15 EST 2002 + Releasing GNUnet 0.4.5. + +Fri Aug 16 16:43:39 EST 2002 + Added feature that will allow the specification of + multiple URLs for downloading the initial hostlist. + +Mon Aug 12 02:28:14 EST 2002 + Fixed big problem in requestmanager that would + make downloads *very* slow for no good reason + at all (ttl increment in wrong place would make + us defer the next request for more than twice + as long as needed, plus some other minor bugs). + +Mon Aug 12 01:31:03 EST 2002 + Fixed bug #347 (option "-H" to gnunet-clients for + connecting to a remote gnunetd node). + +Mon Aug 12 01:10:17 EST 2002 + Fixed bug #348 (no more scan of the entire database + on startup, instead the databases (gdbm, tdb) contain + an entry that gives the nubmer of entries). Note that + this is not done for contentdatabase_directory. + +Sun Aug 11 17:00:03 EEST 2002 + Crude file insertion capabilities added to gnunet-gtk gui. + +Thu Aug 8 19:13:34 EST 2002 + Added progress bar / printing of insertion status to + gnunet-insert (option "-V"). + +Thu Aug 8 19:02:33 EST 2002 + Cleaning up code (establishing sessions, etc.) + +Thu Aug 8 18:03:05 EST 2002 + Fixed bug #343 (overflow in stats) by moving to + long long. Let's hope that __BYTE_ORDER is + actually defined outside of netinet/in.h. + +Thu Aug 8 17:47:17 EST 2002 + Fixed gnunetd segfaulting if gnunet.conf is not + available. Also, recvfrom returning -1 with + errno == EAGAIN was fixed earlier. + +Wed Jul 31 23:38:36 EST 2002 + Released 0.4.4. + +Wed Jul 31 21:35:53 EST 2002 + Fixed bug with TCP connection that would not + free thread resources and eventually lead to + gnunetd not being able to start new threads + anymore (mantis: #339). + +Tue Jul 30 23:38:51 EST 2002 + Fixed SIGHUP exiting. The main loop was exiting + because recvfrom returned -1 with errno EINTR, + which caused us to break out of the main loop. + Also added gnunetd.pid file to simplify killing + (or re-reading configuration of) the server. + You must specify the PIDFILE in gnunet.conf! + +Tue Jul 30 20:38:47 EST 2002 + Started writing code to enable re-reading of the + configuration file whenever we receive a SIGHUP. + Works, except that after we've read the new + config file, gnunetd exits (unknown why). + +Mon Jul 29 18:52:23 EST 2002 + Added shutdown code that terminates connection when + SIGTERM is received (to avoid keeping lots of UDP + traffic for the next couple of minutes from hosts + that still believe we're up). + +Sat Jul 27 12:39:47 EST 2002 + Added code to measure network load asymmetrically (useful + for DSL users). + +Fri Jul 26 22:46:54 EST 2002 + Released 0.4.3. + +Wed Jul 24 21:13:08 EST 2002 + Fixed bug in locking and segfault (Linux tolerated, + BSD crashed, both in connection.c), added logging service. + +Tue Jul 23 00:41:17 EST 2002 + Made gnunetd fork like a nice deamon should. Also + started to add a logging service. + +Sun Jul 21 20:39:20 EST 2002 + Fixed issue with check_database (index checking too + strict if content is available in database and + on-demand encoded; also a bounds check was missing). + +Sun Jul 21 16:05:20 EST 2002 + Fixed deadlock in heloexchange (knownhost requires + recursive lock). + +Sun Jul 21 02:02:32 EST 2002 + Improved routing table. Now does more dynamic memory + allocation, reducing the fixed-size per slot from 700 + to 56 bytes. Increased number of slots from 512 to + 8092 (which is the optimal number for a 56 kbps + modem connection). + +Sat Jul 20 23:57:06 EST 2002 + Fixed bug that caused problems for files + that were indexed and that had spaces in + the filename. + +Wed Jul 17 22:50:24 EST 2002 + Fixed bug that prohibited a transitive HELO exchange + in many cases. + +Wed Jul 17 01:48:44 EST 2002 + Fixed a couple of bugs in gnunet-check and the + insertion-tools. Now gnunet-check seems to run like + a charm. Running it to detect and fix problems in + the GNUnet databases seems now recommendable :-). + Note that you must stop gnunetd before running + gnunet-check. + +Mon Jul 15 22:27:45 EST 2002 + Added return values for insertion. If we run out of + space (in particular for the fixed-size index + database), we can now communicate the problem to the + user. + gnunet-check is now pretty much feature-complete, + but it takes of course very, very long to run. There + is now also a man-page for gnunet-check. + +Thu Jul 11 11:33:34 EST 2002 + Added randomized order of blocks for the download + (patch by I. Wronsky). + +Thu Jun 20 21:13:21 EST 2002 + Added HANGUP, a message send if one side terminates the connection. + Sending the message is optional, but it is nicer to have it. Also + started on gnunet-check, a tool to check database consistency. + +Thu Jun 20 03:11:01 EST 2002 + Improved handling of collisions in the hashes in the + lookup module (uses no longer a linear scan on the + collisions file but a hashtable for the collisions!). + +Tue Jun 18 20:29:38 EST 2002 + Released GNUnet 0.4.2. + +Tue Jun 18 20:20:55 EST 2002 + Fixed bugs in blacklisting IPs. Added feature to allow specification + which networks are trusted enough to connect to the trusted TCP + port (TCP/2086 no longer needs to be firewalled!). + +Tue Jun 18 02:35:53 EST 2002 + Fixed problems with ttl (negative TTL queries were forwarded), + also better flushing of buffers and fewer SKEY exchanges due to + a now working implementation of the blacklist. A DNS lookup for + the NAT-box-IP configuration was also added. + +Sun Jun 16 04:11:01 EST 2002 + Added code to provide statistics (gnunet-stats). + Incomplete. + +Sun Jun 9 22:56:02 EST 2002 + Released GNUnet 0.4.1. + +Sat Jun 8 05:00:36 EST 2002 + Several small bugfixes (list of shared files not updated on + insertion, highest-bit of trust not interpreted as dirty, + rpm dependency on libextractor added. + Also many improvments to the build process. + +Wed Jun 5 17:01:58 EST 2002 + Made sure that HELOs don't trigger Ping-Pong if we don't + really learn anything new. + +Tue Jun 4 17:17:45 EST 2002 + The port numbers were not in network-byte order. Fixing + this is trivial, but it breaks compatibility with 0.4.0. + Thanks to Rick Kennell for reporting the endianess issue. + +Mon Jun 3 20:35:47 EST 2002 + Fixed bug with CRC not endian-converted in gnunet-gtk. + Added mimetype and filename support to gnunet-gtk. + +Sun Jun 2 03:52:18 EST 2002 + Released 0.4.0. + +Sat Jun 1 22:13:12 EST 2002 + Added three-way handshake for SKEY exchange. Not tested. + +Sat Jun 1 16:55:18 EST 2002 + Fixed potential DDoS problem where malicious hosts could + trick GNUnet servers to repeatedly probe a non-partitipating host + trying to establish a connection. I wonder how many other + p2p systems are vulnerable. (Fix: after HELO, play PING-PONG). + The endianess issues should be fixed throughout the system, but + not tested on a real machine so far. + +Sat May 25 15:55:11 EST 2002 + Moved to new CVS server. First changes towards 0.4.0: + * mostly-big-endian + * insert/index via TCP + * bugfixes (mostly performance) + +Sat May 18 16:00:06 EST 2002 + Added mimetype, filename and version number to RootNodes + (mostly incompatible change!). Added automatic generic keyword + and mime-type extraction via libextractor to gnunet-insert. + +Tue May 14 23:59:40 EST 2002 + New storage database is starting to look good. We can now store + the data in a directory (one file per block), a gdbm database, + and presumably (not tested) in a tdb database. + +Sat May 11 22:10:56 EST 2002 + Completed, deployed and tested the new TCPIO code. This changes + the gnunetd-client protocol. Essentially, we convert the TCP stream + into records with a length and type header. This should allow us + to fix bug #212 and add other features in the future. The current + change is really only changing the core TCP code and not anything + around it. We should deploy some demultiplexing code later. + +Tue May 7 20:56:40 EST 2002 + Added IP blacklisting (for virtual private networks). + +Sat May 4 14:08:23 EST 2002 + Fixed bug with bad insertion of files smaller than 1k. + +Fri May 3 23:25:16 EST 2002 + Added IP change detection (useful for dialup) [bug #272]. + Added code to ensure that a HELO is life instantly + after receiving it, fixing the 'unknown host, + refusing SKEY problem' (bug #273). Other minor + bugfixes (#274, #283). + +Sun Apr 14 22:36:03 EST 2002 + Added option to allow NAT boxes not to exchange + foreign HELOs and thus expose the private + network. Fixed bug that all other hosts should + in fact do this exchange. + +Sat Apr 13 11:02:59 EST 2002 + Make sure that files are readable before returning TRUE + in assertIsFile() + +Fri Apr 12 03:01:06 EST 2002 + Added padding messages with random if maximum + packet size is not reached. All encrypted + packets now look absolutely uniform in size + for a non-participating adversary (before, + a host that had few queries may have sent packets + that were less than the maximum size). + +Thu Apr 11 01:43:28 EST 2002 + Added sequence numbers to protocol to defend + against replay attacks (bug #185). + +Wed Apr 10 02:07:25 EST 2002 + Bugfix gnunet-insert-mp3 (endless loop). + Updated documentation. + +Mon Apr 8 00:07:15 EST 2002 + Fixed endless-loop bug when activemigration is turned + on (during startup). + +Fri Apr 5 02:03:13 EST 2002 + Released 0.3.3. + +Fri Apr 5 00:33:42 EST 2002 + gnunet-gtk, the gtk+ based GUI is now functional and + has all the features of gnunet-search and gnunet-download, + including boolean queries. In fact, it is a bit better than + gnunet-download as it shows the progress of the download. + The manpage for gnunet-gtk was updated. Minor bugfixes. + +Mon Mar 25 02:59:13 EST 2002 + Changed writeFile to use a fourth parameter which is the + desired permissions for the file. Files in data/hosts + are now world-readable. Created man pages + +Mon Mar 18 17:56:52 EST 2002 + Released 0.3.2. + +Sun Mar 17 10:47:51 EST 2002 + Got rid of far too frequent key exchange attempts. + Added expiration for very-long-dead host keys. Stopped + forwarding of expired HELOs (receiver drops anyway). + +Wed Mar 14 05:46:20 EST 2002 + Fixed some file location inconsistencies. All files are + now in $HOME/GNUnet. RPM installation points to /var/GNUnet + and the config file is ~/GNUnet/gnunet.conf + Finished port to FreeBSD. This included mostly changes + to src/util/statuscalls.c, but also several changes to + the build system. Added a stat() call in the server code + to make sure the config file exists before sending it to + the OpenSSL conf code. Added getopt to source to fix + portability issues. Changed FREEBSD defs to SOMEBSD, also + changed in configure.in. Compiles and works on at least + FreeBSD 4.5 and OpenBSD 3.0 + +Wed Mar 6 23:15:36 EST 2002 + Added code for 'fast scan' of the database for + content to discard (should be called partial + scan). This improves the startup-time dramatically. + Every source file got the GNU header. + +Tue Mar 5 22:42:36 EST 2002 + Added option for *not* participating in content + migration. Added timeout option to gnunet-search. + gnunetd now periodically (1h) scans for new content, + no restarting required. + +Mon Mar 4 23:21:51 EST 2002 + Optimized routing and content migration. Distance + of the hash to the identity of the local host is + now taken into account for routing. Hosts give + higher priority to content that is close to their + identity (priority towards keeping it). If the + network grows, this should significantly improve + the performance. Also, the choice of the hosts + for routing is now based on proximity (to the + query), the activity level of the host and its + credit ranking. + +Sun Mar 3 00:14:58 EST 2002 + Implemented binary queries ("AND") for gnunet-search. + Made sure that content is not downloaded again if + already present (if there is other content, we + overwrite). Fixed bug in gnunet-download + (uninitialzied time-to-live). + +Sat Mar 2 01:57:37 EST 2002 + Finished porting the download-code to C. Now files can + be downloaded in using shell commands. No GUI though. + Released GNUnet v0.3.1. + +Wed Feb 20 23:47:19 EST 2002 + Big CVS moving operation. + +Sat Feb 16 23:17:27 EST 2002 + Started migration to GNUnet. + +Sun Feb 3 01:20:37 EST 2002 + Extracted crc32 method from zlib and put only that method into + primitives. Reduces our memory footprint (if nobody else uses + zlib) and we no longer depend no that library (always good). + +Sat Feb 2 22:56:32 EST 2002 + Building final tarball for v0.3.0. + +Wed Jan 30 23:41:04 EST 2002 + Created mp32gnet, a tool to automaticall index mp3 files + using information from the mp3 header as keywords (title, + artist, album, comments). The mp3 parsing code comes from + the GPL tool mp3info. + +Tue Jan 29 17:36:48 EST 2002 + Fixed bug with files that were not closed under certain + circumstances and lead to an exhaustion of the number of + concurrently open files. + +Mon Jan 21 23:34:44 EST 2002 + Bumping version numbers to v0.3.0 (not yet released, needs some + more testing to be on the safe side). + +Sun Jan 20 02:09:06 EST 2002 + Content gathering now discards the least important + content in favour of new, more important content (if + there is not space for all content). The cron + management is now used everywhere. The rpm, the init-script + and the gproxy shell script have been revised. + +Sun Jan 13 23:17:58 EST 2002 + Created cron management, replacing old control + thread (allows for better timing of events). + EvaluateContent now gets the priority of the + query that the content had. + +Sun Jan 13 00:54:56 EST 2002 + Improved choice in number of hosts to forward + queries to (now dynamic, depending on priority, etc.) + Removed many, many allocations in print statements + which also caused memory leaks if active (see + debugging.h). + Added CRC checking of the root node in GProxy. Fixed + problem with CRC in IBlocks for large files. + Added dialog to GProxy to choose where to save the file. + +Sat Jan 5 14:25:31 EST 2002 + Optimized routing table. Routing table is now a hashtable + (collisions are handled by droping either the former or the + new entry). Each bucket has it's own lock, the global + semaphore is gone. The table has many more entries (we can + afford that now that there is no longer a linear search). + +Wed Dec 26 19:30:41 CET 2001 + Created v0.2.0 + +Tue Dec 25 21:24:18 CET 2001 + Fixed TTL errors that made queries loop. Added host-evaluation + to policy (drop packets from untrusted hosts under load). Found that CRC-errors + are related to policy decisions ("drop"), cosmetic fix. + +Sun Nov 25 08:10:52 EST 2001 + Added triple-hash functionality and on-demand encoding (lookup.c). + +Sat Nov 24 07:46:10 EST 2001 + Added randomized choice of hosts for the hosttable. + +Thu Nov 22 04:57:57 EST 2001 + Fixed another bunch of big bugs, tested, seems to work smoothly. Creating V0.1.0. + +Mon Nov 19 01:22:42 EST 2001: + Fixed biggest (show-stopper) bugs. Creating V0.0.3 + +Fri Oct 26 02:20:00 EST 2001: + Created ChangeLog.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + 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. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. 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. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +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 `..'. + + 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. + +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'. + + 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. + + 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'. + +Optional Features +================= + +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. + +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 bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /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 the options to `configure', and exit. + +`--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. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 000000000..c736a533d --- /dev/null +++ b/Makefile.am @@ -0,0 +1,14 @@ +INCLUDES = -I$(top_srcdir)/src/include +SUBDIRS = contrib src po + +EXTRA_DIST = \ + ABOUT-NLS \ + config.rpath \ + install-sh \ + HACKING \ + UPDATING \ + PLATFORMS \ + acinclude.m4 + +ACLOCAL_AMFLAGS = -I m4 + diff --git a/NEWS b/NEWS new file mode 100644 index 000000000..898a3dab3 --- /dev/null +++ b/NEWS @@ -0,0 +1 @@ +See ChangeLog. diff --git a/RATIONALE b/RATIONALE new file mode 100644 index 000000000..e68dcb883 --- /dev/null +++ b/RATIONALE @@ -0,0 +1,246 @@ +This document is a summary of why we're moving to GNUnet NG and what +this major redesign tries to address. + +First of all, the redesign does not (intentionally) change anything +fundamental about the application-level protocols or how files are +encoded and shared. However, it is not protocol-compatible due to +other changes that do not relate to the essence of the application +protocols. + + +The redesign tries to address the following major problem groups +describing isssues that apply more or less to all GNUnet versions +prior to 0.9.x: + + +PROBLEM GROUP 1 (scalability): +* The code was modular, but bugs were not. Memory corruption + in one plugin could cause crashes in others and it was not + always easy to identify the culprit. This approach + fundamentally does not scale (in the sense of GNUnet being + a framework and a GNUnet server running hundreds of + different application protocols -- and the result still + being debuggable, secure and stable). +* The code was heavily multi-threaded resulting in complex + locking operations. GNUnet 0.8.x had over 70 different + mutexes and almost 1000 lines of lock/unlock operations. + It is challenging for even good programmers to program or + maintain good multi-threaded code with this complexity. + The excessive locking essentially prevents GNUnet from + actually doing much in parallel on multicores. +* Despite efforts like Freeway, it was virtually + impossible to contribute code to GNUnet that was not + writen in C/C++. +* Changes to the configuration almost always required restarts + of gnunetd; the existence of change-notifications does not + really change that (how many users are even aware of SIGHUP, + and how few options worked with that -- and at what expense + in code complexity!). +* Valgrinding could only be done for the entire gnunetd + process. Given that gnunetd does quite a bit of + CPU-intensive crypto, this could not be done for a system + under heavy (or even moderate) load. +* Stack overflows with threads, while rare under Linux these + days, result in really nasty and hard-to-find crashes. +* structs of function pointers in service APIs were + needlessly adding complexity, especially since in + most cases there was no polymorphism + +SOLUTION: +* Use multiple, lously-coupled processes and one big select + loop in each (supported by a powerful library to eliminate + code duplication for each process). +* Eliminate all threads, manage the processes with a + master-process (gnunet-arm, for automatic restart manager) + which also ensures that configuration changes trigger the + necessary restarts. +* Use continuations (with timeouts) as a way to unify + cron-jobs and other event-based code (such as waiting + on network IO). + => Using multiple processes ensures that memory corruption + stays localized. + => Using multiple processes will make it easy to contribute + services written in other language(s). + => Individual services can now be subjected to valgrind + => Process priorities can be used to schedule the CPU better + Note that we can not just use one process with a big + select loop because we have blocking operations (and the + blocking is outside of our control, thanks MySQL, + sqlite, gethostbyaddr, etc.). So in order to perform + reasonably well, we need some construct for parallel + execution. + + RULE: If your service contains blocking functions, it + MUST be a process by itself. +* Eliminate structs with function pointers for service APIs; + instead, provide a library (still ending in _service.h) API + that transmits the requests nicely to the respective + process (easier to use, no need to "request" service + in the first place; API can cause process to be started/stopped + via ARM if necessary). + + +PROBLEM GROUP 2 (UTIL-APIs causing bugs): +* The existing logging functions were awkward to use and + their expressive power was never really used for much. +* While we had some rules for naming functions, there + were still plenty of inconsistencies. +* Specification of default values in configuration could + result in inconsistencies between defaults in + config.scm and defaults used by the program; also, + different defaults might have been specified for the + same option in different parts of the program. +* The TIME API did not distinguish between absolute + and relative time, requiring users to know which + type of value some variable contained and to + manually convert properly. Combined with the + possibility of integer overflows this is a major + source of bugs. +* The TIME API for seconds has a theoretical problem + with a 32-bit overflow on some platforms which is + only partially fixed by the old code with some + hackery. + +SOLUTION: +* Logging was radically simplified. +* Functions are now more conistently named. +* Configuration has no more defaults; instead, + we load a global default configuration file + before the user-specific configuration (which + can be used to override defaults); the global + default configuration file will be generated + from config.scm. +* Time now distinguishes between + struct GNUNET_TIME_Absolute and + struct GNUNET_TIME_Relative. We use structs + so that the compiler won't coerce for us + (forcing the use of specific conversion + functions which have checks for overflows, etc.). + Naturally the need to use these functions makes + the code a bit more verbose, but that's a good + thing given the potential for bugs. +* There is no more TIME API function to do anything + with 32-bit seconds + + +PROBLEM GROUP 3 (statistics): +* Databases and others needed to store capacity values + similar to what stats was already doing, but + across process lifetimes ("state"-API was a partial + solution for that, but using it was clunky) +* Only gnunetd could use statistics, but other + processes in the GNUnet system might have had + good uses for it as well + +SOLUTION: +* New statistics library and service that offer + an API to inspect and modify statistics +* Statistics are distinguished by service name + in addition to the name of the value +* Statistics can be marked as persistent, in + which case they are written to disk when + the statistics service shuts down. + => One solution for existing stats uses, + application stats, database stats and + versioning information! + + +PROBLEM GROUP 4 (Testing): +* The existing structure of the code with modules + stored in places far away from the test code + resulted in tools like lcov not giving good results. +* The codebase had evolved into a complex, deeply + nested hierarchy often with directories that + then only contained a single file. Some of these + files had the same name making it hard to find + the source corresponding to a crash based on + the reported filename/line information. +* Non-trivial portions of the code lacked good testcases, + and it was not always obvious which parts of the code + were not well-tested. + +SOLUTION: +* Code that should be tested together is now + in the same directory. +* The hierarchy is now essentially flat, each + major service having on directory under src/; + naming conventions help to make sure that + files have globally-unique names +* All code added to the new repository must + come with testcases with reasonable coverage. + + +PROBLEM GROUP 5 (core/transports): +* The new DV service requires session key exchange + between DV-neighbours, but the existing + session key code can not be used to achieve this. +* The core requires certain services + (such as identity, pingpong, fragmentation, + transport, traffic, session) which makes it + meaningless to have these as modules + (especially since there is really only one + way to implement these) +* HELLO's are larger than necessary since we need + one for each transport (and hence often have + to pick a subset of our HELLOs to transmit) +* Fragmentation is done at the core level but only + required for a few transports; future versions of + these transports might want to be aware of fragments + and do things like retransmission +* Autoconfiguration is hard since we have no good + way to detect (and then use securely) our external IP address +* It is currently not possible for multiple transports + between the same pair of peers to be used concurrently + in the same direction(s) +* We're using lots of cron-based jobs to periodically + try (and fail) to build and transmit + +SOLUTION: +* Rewrite core to integrate most of these services + into one "core" service. +* Redesign HELLO to contain the addresses for + all enabled transports in one message (avoiding + having to transmit the public key and signature + many, many times) +* With discovery being part of the transport service, + it is now also possible to "learn" our external + IP address from other peers (we just add plausible + addresses to the list; other peers will discard + those addresses that don't work for them!) +* New DV will consist of a "transport" and a + high-level service (to handle encrypted DV + control- and data-messages). +* Move expiration from one field per HELLO to one + per address +* Require signature in PONG, not in HELLO (and confirm + on address at a time) +* Move fragmentation into helper library linked + against by UDP (and others that might need it) +* Link-to-link advertising of our HELLO is transport + responsibility; global advertising/bootstrap remains + responsibility of higher layers +* Change APIs to be event-based (transports pull for + transmission data instead of core pushing and failing) + + +PROBLEM GROUP 6 (FS-APIs): +* As with gnunetd, the FS-APIs are heavily threaded, + resulting in hard-to-understand code (slightly + better than gnunetd, but not much). +* GTK in particular does not like this, resulting + in complicated code to switch to the GTK event + thread when needed (which may still be causing + problems on Gnome, not sure). +* If GUIs die (or are not properly shutdown), state + of current transactions is lost (FSUI only + saves to disk on shutdown) + +SOLUTION (draft, not done yet, details missing...): +* Eliminate threads from FS-APIs + => Open question: how to best write the APIs to + allow integration with diverse event loops + of GUI libraries? +* Store FS-state always also on disk + => Open question: how to do this without + compromising state/scalability? + diff --git a/README b/README new file mode 100644 index 000000000..84330e2ab --- /dev/null +++ b/README @@ -0,0 +1,257 @@ + Welcome to GNUnet + + +What is GNUnet? +=============== + +GNUnet is peer-to-peer framework focusing on security. 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 part of the GNU project (http://www.gnu.org/). + +This is a BETA release. While there are no known significant bugs, we +are still changing significant aspects of the system in any other +version. While we believe that the system is usable, quite a few +important features -- which would improve performance make the life of +users easier -- are still missing. Also, the documentation may not be +adequate for inexperienced users. + +For a longer description of the GNUnet System see our webpages +http://www.gnu.org/software/gnunet/ and http://gnunet.org/. + + +Dependencies: +============= + +For the impatient, here is the list of immediate dependencies for +running GNUnet: + +- libextractor >= 0.5.20b +- libgcrypt >= 1.2 +- libgmp >= 4.0 +- libcurl >= 7.15.4 +- libltdl >= 2.2 (part of GNU libtool) +- libguile >= 1.8 (required for gnunet-setup) +- GNU adns >= 1.0 (strongly recommended) +- mysql >= 5.0 (strongly recommended) +- sqlite >= 3.0 (alternative to MySQL) + +Certain gnunet-setup plugins would also like to have: +- GTK >= 2.6.0 +- Qt >= 4.0 +- dialog >= 1.0-20051207 +- ncurses + +Certain transports would also like to have: +- libmicrohttpd >= 0.4.0b +- libcurl >= 7.15.4 +- libesmtp >= 1.0.4 + + +Recommended autotools for compiling the SVN version are: +- autoconf >= 2.59 +- automake >= 1.9.4 +- libtool >= 1.5 +- libltdl >= 2.2.0 (only in Debian experimental) + +See also README.debian for a list of Debian packages. + + +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 http://gnunet.org/documentation.php3. + + +If you install from source, you need to install libextractor +first (download from http://gnunet.org/libextractor/). Then +you can start the actual GNUnet compilation process with: + +$ ./configure --prefix=$HOME --with-extractor=$HOME +$ make +# make install +# gnunet-setup -d +# gnunetd + +This will compile and install GNUnet to ~/bin/, ~/lib/ and ~/man/. +gnunet-setup will create the daemon configuration (-d); this step is +interactive. You can run gnunet-setup as root for a system-wide +installation or as a particular user to create a personal +installation. If you do not want to run gnunetd as root, gnunet-setup +can be used to add a user "gnunet". Data will then be stored in +/var/lib/GNUnet and gnunetd will run as that user. Note that +additional, per-user configuration files (~/.gnunet/gnunet.conf) also +need to be created by each user by running gnunet-setup without the -d +option. Depending on your operating system the wizards of +gnunet-setup can also be used to create an init script that starts +gnunetd each time the system boots. For more general information +about the GNU build process read the INSTALL file. + +GNUnet requires the GNU MP library (http://www.gnu.org/software/gmp/) +and libgcrypt. You can specify the path to libgcrypt by passing +"--with-gcrypt=PATH" to configure. You will also need either sqlite +(version 3 or higher) or MySQL (version 5.0 or higher). + +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 +============= + +GNUnet uses two types of configuration files, one for the daemon +(called gnunetd.conf) and one for each user (gnunet.conf). You can +create and edit these configuration files with the gnunet-setup tool. +You need to add the option "-d" to gnunet-setup in order to edit +gnunetd.conf (by default, gnunet-setup will edit gnunet.conf). The +defaults that are created the first time you run gnunet-setup are +usually ok, you may want to adjust the limitations (space consumption, +bandwidth, etc.) though. The configuration files are human-readable; +gnunetd's configuration is typically located at "/etc/gnunetd.conf". +The per-user configuration file should be at "~/.gnunet/gnunet.conf". +A default version of the per-user configuration will automatically +be created whenever you run any tool that needs that particular +cofniguration file. + +You MUST create /etc/gnunetd.conf explicitly before starting gnunetd, +and the recommended way to do this is to run gnunet-setup -d (plus +possibly options to specify which user interface you would perfer). + +If you want to use a different configuration file, pass the name of +the configuration file as an argument with the option "-c" to any +GNUnet application. Sending a SIGHUP to the gnunetd process will +cause gnunetd to re-read the configuration file. Note that not all +options can be changed at runtime this way (e.g. to change any port +number, you must fully restart gnunetd). + +After changing certain options (or updating GNUnet) you must re-run +gnunet-update. + + +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 "gnunetd.conf" +contains URLs from where gnunetd 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 +gnunetd by periodically executing + +$ cat $GNUNETD_HOME/data/hosts/* > the_file + +If the solution with the URL is not feasible for your situation, you +can also add hosts manually. The GNUnet webpage has a public +directory of hostkeys under http://gnunet.org/hosts/. You +can of course use any other source for these files. Copy the hostkeys +to "$GNUNETD_HOME/data/hosts/" (where $GNUNETD_HOME is the +directory specified in the /etc/gnunetd.conf configuration file). + +Now start the local node using "gnunetd". gnunetd should run 24/7 if +you want to maximize your anonymity. You may start it as a service +with "/etc/init.d/gnunetd start". To insert files into GNUnet, use +the "gnunet-insert" command. + +The GTK user interface is shipped separately from GNUnet. After +downloading and installing gnunet-gtk, you can invoke the GUI with: + +$ gnunet-gtk + +For Qt/KDE users, there is also a QT user interface (also shipped +separately). If you install gnunet-qt, you can invoke the GUI with: + +$ gnunet-qt + +If you want to use the shell (part of this distribution), use + +$ gnunet-search KEYWORD + +This will display a list of results to the console. Then use + +$ gnunet-download -o FILENAME GNUNET_URI + +to retrieve a file. The GNUNET_URI is printed by gnunet-search +together with a description. + +In order to share files, the easiest way is to create a directory +with the files (and directories) that you want to share and run + +$ nohup gnunet-auto-share NAME-OF-THE-DIRECTORY & + +For further documentation, see our webpage. + + +Hacking GNUnet +============== + +Contributions are welcome, please submit bugs to +https://gnunet.org/mantis/. 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 + +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/mantis/. + + +Running http on port 80 +======================= + +In order to hide GNUnet's HTTP traffic perfectly, you might consider +running GNUnet's HTTP transport on port 80. However, you should not +run GNUnet as root. Instead, forward port 80 to say 8080 with this +command (as root, in your startup scripts): + +# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080 + +Then set in the HTTP section of gnunetd.conf the "ADVERTISED-PORT" +to "80" and "PORT" to 8080. 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). + + +Running the SMTP transport +========================== + +Running GNUnet over SMTP (e-mail) is a bit more involved.

If set to YES, you simply specify the maximum bandwidth (upstream and downstream) that GNUnet is allowed to use and GNUnet will stick to those limitations. This is useful if your overall bandwidth is so large that the limit is mostly used to ensure that enough capacity is left for other applications. Even if you want to dedicate your entire connection to GNUnet you should not set the limits to values higher than what you have since GNUnet uses those limits to determine for example the number of connections to establish (and it would be inefficient if that computation yields a number that is far too high). + +While basic bandwidth limitation is simple and always works, there are some situations where it is not perfect. Suppose you are running another application which performs a larger download. During that particular time, it would be nice if GNUnet would throttle its bandwidth consumption (automatically) and resume using more bandwidth after the download is complete. This is obviously advanced magic since GNUnet will have to monitor the behavior of other applications. Another scenario is a monthly cap on bandwidth imposed by your ISP, which you would want to ensure is obeyed. Here, you may want GNUnet to monitor the traffic from other applications to ensure that the combined long-term traffic is within the pre-set bounds. Note that you should probably not set the bounds tightly since GNUnet may observe that the bounds are about to be broken but would be unable to stop other applications from continuing to use bandwidth. + +If either of these two scenarios applies, set BASICLIMITING to NO. Then set the bandwidth limits to the COMBINED amount of traffic that is acceptable for both GNUnet and other applications. GNUnet will then immediately throttle bandwidth consumption if the short-term average is above the limit, and it will also try to ensure that the long-term average is below the limit. Note however that using NO can have the effect of GNUnet (almost) ceasing operations after other applications perform high-volume downloads that are beyond the defined limits. GNUnet would reduce consumption until the long-term limits are again within bounds. + +NO only works on platforms where GNUnet can monitor the amount of traffic that the local host puts out on the network. This is only implemented for Linux and Win32.

The tool can be used to test +both the correctness of the software as well as the correctness +of the configuration. gnunet\-transport features two modes, +called loopback mode and ping mode. In loopback mode the test is limited to testing if the +transport can be used to communicate with itself (loopback). +This mode does not include communication with other peers which +may be blocked by firewalls and other general Internet connectivity +problems. The loopback mode is particularly useful to test +the SMTP transport service since this service is fairly hard to +configure correctly and most problems can be reveiled by just +testing the loopback. In ping mode the tool will attempt to download +peer advertisements from the URL specified in the configuration file +and then try to contact each of the peers. Note that it is perfectly +normal that some peers do not respond, but if no peer responds something +is likely to be wrong. The configuration is always taken +from the configuration file. Do not run gnunetd while running +gnunet\-transport since the transport services cannot +be used by two processes at the same time. +.PP +gnunet\-transport will always produce an error\-message for +the NAT transport in loopback mode. If NAT is configured in accept\-mode (as in, +accept connections from peers using network address translation), +the check will fail with the message "could not create HELO", +which is correct since the peer itself is clearly not going to +advertise itself as a NAT. If the peer is configured in NAT\-mode, +that is, the peer is behind a NAT box, the message will be +'could not connect'. For NAT, both messages are NOT errors +but exactly what is supposed to happen. +.PP +Similarly, a NAT\-ed peer should typically configure the TCP transport +to use port 0 (not listen on any port). In this case, +gnunet\-transport will print 'could not create HELO' for the +TCP transport. This is also ok. In fact, a correctly configured +peer using NAT should give just two errors (could not connect for +tcp and could not create HELO for NAT) when tested using +gnunet\-transport\. The reason is, that gnunet\-transport\ +only tests loopback connectivity, and for a NAT\-ed peer, that just +does not apply. +.PP +Note that in ping mode the HTTP download times out after 5 minutes, +so if the list of peers is very large and not all peers can be +queried within the 5 minutes the tool may abort before trying all +peers. +.TP +\fB\-c \fIFILENAME\fR, \fB\-\-config=\fIFILENAME\fR +use config file (default: /etc/gnunetd.conf) +.TP +\fB\-h\fR, \fB\-\-help\fR +print help page +.TP +\fB\-L \fILOGLEVEL\fR, \fB\-\-loglevel=\fILOGLEVEL\fR +change the loglevel.

[Page 1] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + +1. Introduction + + Network Address Translation (NAT) is a method of sharing one public + internet address with a number of devices. This document is focused + on what "IP Network Address Translator (NAT) Terminology and + Considerations" [RFC 2663] calls "NAPTs" (Network Address/Port + Translators). A full description of NAT is beyond the scope of this + document. The following brief overview will cover the aspects + relevant to this port mapping protocol. For more information on + NAT, see "Traditional IP Network Address Translator" [RFC 3022]. + + NATs have one or more public IP addresses. A private network is set + up behind the NAT. Devices behind the NAT are assigned private + addresses and the private address of the NAT device is used as the + gateway. + + When a packet from any device behind the NAT is sent to an address on + the public internet, the packet first passes through the NAT box. The + NAT box looks at the source port and address. In some cases, a NAT + will also keep track of the destination port and address. The NAT + then creates a mapping from the private address and private port to a + public address and public port if a mapping does not already exist. + The NAT box replaces the private address and port number in the + packet with the public entries from the mapping and sends the packet + on to the next gateway. + + When a packet from any address on the internet is received on the + NAT's public side, the NAT will look up the destination port (public + port) in the list of mappings. If an entry is found, it will contain + the private address and port that the packet should be sent to. The + NAT gateway will then rewrite the destination address and port with + those from the mapping. The packet will then be forwarded to the new + destination addresses. If the packet did not match any mapping, the + packet will most likely be dropped. Various NATs implement different + strategies to handle this. The important thing to note is that if + there is no mapping, the NAT does not know which private address the + packet should be sent to. + + Mappings are usually created automatically as a result of observing + outbound traffic. There are a few exceptions. Some NATs may allow + manually-created permanent mappings that map a public port to a + specific private IP address and port. Such a mapping allows incoming + connections to the device with that private address. Some NATs also + implement a default mapping where any inbound traffic that does not + match a mapping will always be forwarded to a specific private + address. Both types of mappings are usually set up manually through + some configuration tool. + + Without these manually-created inbound port mappings, clients behind + the NAT would be unable to receive inbound connections, which + represents a loss of connectivity when compared to the original + + +Expires 14th March 2007 Cheshire, et al. [Page 2] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + + Internet architecture [ETEAISD]. For those who view this loss of + connectivity as a bad thing, NAT-PMP allows clients to operate much + more like a host directly connected to the unrestricted public + Internet, with an unrestricted public IP address. NAT-PMP allows + client hosts to communicate with the NAT gateway to request the + creation of inbound mappings on demand. Having created a NAT mapping + to allow inbound connections, the client can then record its public + IP address and public port number in a public registry (e.g. the + world-wide Domain Name System) or otherwise make it accessible to + peers that wish to communicate with it. + + +2. Conventions and Terminology Used in this Document + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in "Key words for use in + RFCs to Indicate Requirement Levels" [RFC 2119]. + + +3. Protocol and Packet Format + + NAT Port Mapping Protocol runs over UDP. Every packet starts with an + 8 bit version followed by an 8 bit operation code. + + This document specifies version 0 of the protocol. Any NAT-PMP + gateway implementing this version of the protocol, receiving a + packet with a version number other than 0, MUST return result code 1 + (Unsupported Version). + + Opcodes between 0 and 127 are client requests. Opcodes from 128 to + 255 are server responses. Responses always contain a 16 bit result + code in network byte order. A result code of zero indicates success. + Responses also contain a 32 bit unsigned integer corresponding to the + number of seconds since the NAT gateway was rebooted or since its + port mapping state was reset. + + This protocol SHOULD only be used when the client determines that + its primary IPv4 address is in one of the private IP address ranges + defined in "Address Allocation for Private Internets" [RFC 1918]. + This includes the address ranges 10/8, 172.16/12, and 192.168/16. + + Clients always send their Port Mapping Protocol requests to their + default gateway, as learned via DHCP [RFC 2131], or similar means. + This protocol is designed for small home networks, with a single + logical link (subnet) where the client's default gateway is also the + NAT translator for that network. For more complicated networks where + the NAT translator is some device other than the client's default + gateway, this protocol is not appropriate. + + + + +Expires 14th March 2007 Cheshire, et al. [Page 3] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + +3.1 Requests and Responses + + NAT gateways are often low-cost devices, with limited memory and + CPU speed. For this reason, to avoid making excessive demands on + the NAT gateway, clients machines SHOULD NOT issue multiple requests + simultaneously in parallel. If a client needs to perform multiple + requests (e.g. on boot, wake from sleep, network connection, etc.) + it SHOULD queue them and issue them serially one at a time. Once the + NAT gateway responds to one request the client machine may issue the + next. In the case of a fast NAT gateway, the client may be able to + complete requests at a rate of hundreds per second. In the case of + a slow NAT gateway that takes perhaps half a second to respond to + a NAT-PMP request, the client SHOULD respect this and allow the + NAT gateway to operate at the pace it can manage, and not overload + it by issuing requests faster than the rate it's answering them. + + To determine the puclic IP address or request a port mapping, + a NAT-PMP client sends its request packet to port 5351 of its + configured gateway address, and waits 250ms for a response. If no + NAT-PMP response is received from the gateway after 250ms, the client + retransmits its request and waits 500ms. The client SHOULD repeat + this process with the interval between attempts doubling each time. + If, after sending its 9th attempt (and then waiting for 64 seconds), + the client has still received no response, then it SHOULD conclude + that this gateway does not support NAT Port Mapping Protocol and + MAY log an error message indicating this fact. In addition, if the + NAT-PMP client receives an "ICMP Port Unreachable" message from the + gateway for port 5351 then it can skip any remaining retransmissions + and conclude immediately that the gateway does not support NAT-PMP. + + As a performance optimization the client MAY record this information + and use it to suppress further attempts to use NAT-PMP, but the + client should not retain this information for too long. In + particular, any event that may indicate a potential change of gateway + or a change in gateway configuration (hardware link change + indication, change of gateway MAC address, acquisition of new DHCP + lease, receipt of NAT-PMP announcement packet from gateway, etc.) + should cause the client to discard its previous information regarding + the gateway's lack of NAT-PMP support, and send its next NAT-PMP + request packet normally. + + +3.2 Determining the Public Address + + To determine the public address, the client behind the NAT sends the + following UDP payload to port 5351 of the configured gateway address: + + 0 1 + 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Vers = 0 | OP = 0 | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + +Expires 14th March 2007 Cheshire, et al.

However, the gateway is not obliged to assign + the port requested, and may choose not to, either for policy reasons + (e.g. port 80 is reserved and clients may not request it) or because + that port has already been assigned to some other client. Because + of this, some product developers have questioned the value of having + the Requested Public Port field at all. The reason is for failure + recovery. Most low-cost home NAT gateways do not record temporary + port mappings in persistent storage, so if the gateway crashes or is + rebooted, all the mappings are lost.

For example, if a client requests to map TCP port 80, + as long as the client maintains the lease for that TCP port mapping, + another client with a different IP address MUST NOT be able to + successfully acquire the mapping for UDP port 80. + + The client normally requests the public port matching the private + port. If that public port is not available, the NAT gateway MUST + return a public port that is available or return an error code if + no ports are available. + + The source address of the packet MUST be used for the private address + in the mapping.

This is necessary to handle the case where + a client requests a mapping with requested public port X, and is + granted a mapping with actual public port Y, but the acknowledgement + packet gets lost. When the client retransmits its mapping request, + it should get back the same positive acknowledgement as was sent (and + lost) the first time. + + The NAT gateway SHOULD NOT accept mapping requests destined to the + NAT gateway's public IP address or received on its public network + interface. Only packets received on the private interface(s) with + a destination address matching the private address(es) of the NAT + gateway should be allowed. + + The NAT gateway MUST fill in the "Seconds Since Start of Epoch" field + with the time elapsed since its port mapping table was initialized on + startup or reset for any other reason (see Section 3.6 "Seconds Since + Start of Epoch"). + + The Port Mapping Lifetime is an unsigned integer in seconds.

The response MUST contain a result code of 0, + the private port as indicated in the deletion request, a public port + of 0, and a lifetime of 0. The NAT gateway MUST respond to a request + to destroy a mapping that does not exist as if the request were + successful. This is because of the case where the acknowledgement is + lost, and the client retransmits its request to delete the mapping. + In this case the second request to delete the mapping MUST return the + same response packet as the first request. + + If the deletion request was unsuccessful, the response MUST contain a + non-zero result code and the requested mapping; the lifetime is + undefined (MUST be set to zero on transmission, and MUST be ignored + on reception).

A client MAY + choose to do this when it first acquires a new IP address in order to + protect itself from port mappings that were performed by a previous + owner of the IP address. After receiving such a deletion request, + the gateway MUST delete all its UDP or TCP port mappings (depending + on the opcode). The gateway responds to such a deletion request with + a response as described above, with the private port set to zero. If + the gateway is unable to delete a port mapping, for example, because + the mapping was manually configured by the administrator, the gateway + MUST still delete as many port mappings as possible, but respond with + a non-zero result code.

Since the server does not understand the format of + opcode 17, it may not know what to place after the result code. In + some cases, relevant data may follow the opcode to identify the + operation that failed. For example, a client may request a mapping + but that mapping may fail due to resource exhaustion.

Whenever a client receives any packet from the NAT + gateway, either gratuitously or in response to a client request, the + client computes its own conservative estimate of the expected SSSOE + value by taking the SSSOE value in the last packet it received from + the gateway and adding 7/8 (87.5%) of the time elapsed since that + packet was received. If the SSSOE in the newly received packet is + less than the client's conservative estimate by more than one second, + then the client concludes that the NAT gateway has undergone a reboot + or other loss of port mapping state, and the client MUST immediately + renew all its active port mapping leases as described in Section 3.7 + "Recreating Mappings On NAT Gateway Reboot". + + + + +Expires 14th March 2007 Cheshire, et al.

When the NAT gateway powers on or clears its port mapping + state as the result of a configuration change, it MUST reset the + epoch time and re-announce its IP address as described in Section + 3.2.1 "Announcing Address Changes". Reception of this packet where + time has apparently gone backwards serves as a hint to clients + on the network that they SHOULD immediately send renewal packets + (to immediately recreate their mappings) instead of waiting until + the originally scheduled time for those renewals. Clients who miss + receiving those gateway announcement packets for any reason will + still renew their mappings at the originally scheduled time and cause + their mappings to be recreated; it will just take a little longer for + these clients. + + A mapping renewal packet is formatted identically to an original + mapping request; from the point of view of the client it is a + renewal of an existing mapping, but from the point of view of the + freshly-rebooted NAT gateway it appears as a new mapping request. + + This self-healing property of the protocol is very important. + + The remarkable reliability of the Internet as a whole derives + in large part from the fact that important state is held in the + endpoints, not in the network itself [ETEAISD]. Power-cycling an + Ethernet switch results only in a brief interruption in the flow + of packets; established TCP connections through that switch are not + broken, merely delayed for a few seconds. Indeed, an old Ethernet + switch can even be replaced with a new one, and as long as the cables + are transferred over reasonably quickly, after the upgrade all the + TCP connections that were previously going though the old switch will + be unbroken and now going through the new one. The same is true of + IP routers, wireless base stations, etc. The one exception is NAT + gateways. Because the port mapping state is required for the NAT + gateway to know where to forward inbound packets, loss of that state + breaks connectivity through the NAT gateway. By allowing clients to + detect when this loss of NAT gateway state has occurred, and recreate + it on demand, we turn hard state in the network into soft state, and + allow it to be recovered automatically when needed. + + Without this automatic recreation of soft state in the NAT gateway, + reliable long-term networking would not be achieved.

Imagine this network security + camera uses NAT-PMP or a similar protocol to set up an inbound + port mapping in the NAT gateway so that it can receive incoming + connections from clients the other side of the NAT gateway. + Now, this camera may well operate for weeks, months, or even years. + During that time it's possible that the NAT gateway could experience + a power failure or be rebooted. The user could upgrade the NAT + gateway's firmware, or even replace the entire NAT gateway device + with a newer model. The general point is that if the camera operates + for a long enough period of time, some kind of disruption to the NAT + gateway becomes inevitable. The question is not whether the NAT + gateway will lose its port mappings, but when, and how often. + If the network camera and devices like it on the network can detect + when the NAT gateway has lost its port mappings, and recreate them + automatically, then these disruptions are self-correcting and + invisible to the end user. If, on the other hand, the disruptions are + not self-correcting, and after a NAT gateway reboot the user has to + manually reset or reboot all the other devices on the network too, + then these disruptions are *very* visible to the end user. This + aspect of the design is what makes the difference between a protocol + that keeps on working indefinitely over a time scale of months or + years, and a protocol that works in brief testing, but in the real + world is continually failing and requiring manual intervention to get + it going again. + + When a client renews its port mappings as the result of receiving + a packet where the "Seconds since start of epoch" field (SSSOE) + indicates that a reboot or similar loss of state has occurred, + the client MUST first delay by a random amount of time selected + with uniform random distribution in the range 0 to 5 seconds, and + then send its first port mapping request. After that request is + acknowledged by the gateway, the client may then send its second + request, and so on, as rapidly as the gateway allows. The requests + SHOULD be issued serially, one at a time; the client SHOULD NOT issue + multiple requests simultaneously in parallel. + + The discussion in this section focusses on recreating inbound port + mappings after loss of NAT gateway state, because that is the more + serious problem. Losing port mappings for outgoing connections + destroys those currently active connections, but does not prevent + clients from establishing new outgoing connections. In contrast, + losing inbound port mappings not only destroys all existing inbound + connections, but also prevents the reception of any new inbound + connections until the port mapping is recreated. Accordingly, + we consider recovery of inbound port mappings the more important + priority. However, clients that want outgoing connections to survive + a NAT gateway reboot can also achieve that using NAT-PMP. After + initiating an outbound TCP connection (which will cause the NAT + + +Expires 14th March 2007 Cheshire, et al. [Page 12] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + + gateway to establish an implicit port mapping) the client should send + the NAT gateway a port mapping request for the source port of its TCP + connection, which will cause the NAT gateway to send a response + giving the public port it allocated for that mapping. The client can + then store this information, and use later to recreate the mapping + if it determines that the NAT gateway has lost its mapping state. + + +3.8 NAT Gateways with NAT Function Disabled + + Note that *only* devices currently acting in the role of NAT gateway + should participate in NAT-PMP protocol exchanges with clients. + A network device that is capable of NAT (and NAT-PMP), but is + currently configured not to perform that function, (e.g. it is + acting as a traditional IP router, forwarding packets without + modifying them), MUST NOT respond to NAT-PMP requests from clients, + or send spontaneous NAT-PMP address-change announcements. + + In particular, a network device not currently acting in the role of + NAT gateway should not even respond to NAT-PMP requests by returning + an error code such as "2 - Not Authorized/Refused", since to do so + is misleading to clients -- it suggests that NAT port mapping is + necessary on this network for the client to successfully receive + inbound connections, but is not available because the administrator + has chosen to disable that functionality. + + Clients should also be careful to avoid making unfounded assumptions, + such as the assumption that if the client has an IPv4 address in + one of the RFC 1918 private IP address ranges then that means + NAT necessarily must be in use. Net 10/8 has enough addresses + to build a private network with millions of hosts and thousands + of interconnected subnets, all without any use of NAT. Many + organizations have built such private networks that benefit from + using standard TCP/IP technology, but by choice do not connect + to the public Internet. The purpose of NAT-PMP is to mitigate some + of the damage caused by NAT. It would be an ironic and unwanted + side-effect of this protocol if it were to lead well-meaning but + misguided developers to create products that refuse to work on a + private network *unless* they can find a NAT gateway to talk to. + Consequently, a client finding that NAT-PMP is not available on its + network should not give up, but should proceed on the assumption + that the network may be a traditional routed IP network, with no + address translation being used. This assumption may not always be + true, but it is better than the alternative of falsely assuming + the worst and not even trying to use normal (non-NAT) IP networking. + + If a network device not currently acting in the role of NAT gateway + receives UDP packets addressed to port 5351, it SHOULD respond + immediately with an "ICMP Port Unreachable" message to tell the + client that it needn't continue with timeouts and retransmissions, + and it should assume that NAT-PMP is not available and not needed + on this network. + +Expires 14th March 2007 Cheshire, et al. [Page 13] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + +4. UNSAF Considerations + + The document "IAB Considerations for UNSAF Across NAT" [RFC 3424] + covers a number of issues when working with NATs. RFC 3424 outlines + some requirements for any document that attempts to work around + problems associated with NATs. This section addresses those + requirements. + + +4.1 Scope + + This protocol addresses the needs of TCP and UDP transport peers that + are separated from the public internet by exactly one NAT. Such + peers must have access to some form of directory server for + registering the public IP address and port at which they can be + reached. + + +4.2 Transition Plan + + Any client making use of this protocol SHOULD implement IPv6 support. + If a client supports IPv6 and is running on a device with a global + IPv6 address, that IPv6 address SHOULD be preferred to the IPv4 + public address using this NAT mapping protocol. In case other + clients do not have IPv6 connectivity, both the IPv4 and IPv6 + addresses SHOULD be registered with whatever form of directory server + is used. Preference SHOULD be given to IPv6 addresses when + available. By implementing support for IPv6 and using this protocol + for IPv4, vendors can ship products today that will work under both + scenarios. As IPv6 is more widely deployed, clients of this protocol + following these recommendations will transparently make use of IPv6. + + +4.3 Failure Cases + + Aside from NATs that do not implement this protocol, there are a + number of situations where this protocol may not work. + + +4.3.1 NAT Behind NAT + + Some people's primary IP address, assigned by their ISP, may itself + be a NAT address. In addition, some people may have a public IP + address, but may then double NAT themselves, perhaps by choice or + perhaps by accident. Although it might be possible in principle for + one NAT gateway to recursively request a mapping from the next one, + this document does not advocate that and does not try to prescribe + how it would be done. + + It would be a lot of work to implement nested NAT port mapping + correctly, and there are a number of reasons why the end result might + + +Expires 14th March 2007 Cheshire, et al. [Page 14] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + + not be as useful as we might hope. Consider the case of an ISP that + offers each of its customers only a single NAT address. This ISP + could instead have chosen to provide each customer with a single + public IP address, or, if the ISP insists on running NAT, it could + have chosen to allow each customer a reasonable number of addresses, + enough for each customer device to have its own NAT address directly + from the ISP. If instead this ISP chooses to allow each customer + just one and only one NAT address, forcing said customer to run + nested NAT in order to use more than one device, it seems unlikely + that such an ISP would be so obliging as to provide a NAT service + that supports NAT Port Mapping Protocol. Supposing that such an ISP + did wish to offer its customers NAT service with NAT-PMP so as to + give them the ability to receive inbound connections, this ISP could + easily choose to allow each client to request a reasonable number of + DHCP addresses from that gateway. Remember that Net 10/8 [RFC 1918] + allows for over 16 million addresses, so NAT addresses are not in any + way in short supply. A single NAT gateway with 16 million available + addresses is likely to run out of packet forwarding capacity before + it runs out of private addresses to hand out. In this way the ISP + could offer single-level NAT with NAT-PMP, obviating the need to + support nested NAT-PMP. In addition, an ISP that is motivated to + provide their customers with unhindered access to the Internet by + allowing incoming as well as outgoing connections has better ways + to offer this service. Such an ISP could offer its customers real + public IP addresses instead of NAT addresses, or could even choose + to offer its customers full IPv6 connectivity, where no mapping or + translation is required at all. + + +4.3.2 NATs with Multiple Public IP Addresses + + If a NAT maps private addresses to multiple public addresses, + then it SHOULD pick one of those addresses as the one it will + support for inbound connections, and for the purposes of this + protocol it SHOULD act as if that address were its only address. + + +4.3.3 NATs and Routed Private Networks + + In some cases, a large network may be subnetted. Some sites + may install a NAT gateway and subnet the private network. + Such subnetting breaks this protocol because the router address + is not necessarily the address of the device performing NAT. + + Addressing this problem is not a high priority. Any site with the + resources to set up such a configuration should have the resources to + add manual mappings or attain a range of globally unique addresses. + + Not all NATs will support this protocol. In the case where a client + is run behind a NAT that does not support this protocol, the software + relying on the functionality of this protocol may be unusable. + + +Expires 14th March 2007 Cheshire, et al. [Page 15] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + +4.3.4 Communication Between Hosts Behind the Same NAT + + NAT gateways supporting NAT-PMP should also implement "hairpin + translation". Hairpin translation means supporting communication + between two local clients being served by the same NAT gateway. + + Suppose device A is listening on private address and port 10.0.0.2:80 + for incoming connections. Using NAT-PMP, device A has obtained a + mapping to public address and port x.x.x.x:80, and has recorded this + public address and port in a public directory of some kind. For + example, it could have created a DNS SRV record containing this + information, and recorded it, using DNS Dynamic Update [RFC 3007], in + a publicly accessible DNS server. Suppose then that device B, behind + the same NAT gateway as device A, but unknowing or uncaring of this + fact, retrieves device A's DNS SRV record and attempts to open a TCP + connection to x.x.x.x:80. The outgoing packets addressed to this + public Internet address will be sent to the NAT gateway for + translation and forwarding. Having translated the source address and + port number on the outgoing packet, the NAT gateway needs to be smart + enough to recognize that the destination address is in fact itself, + and then feed this packet back into its packet reception engine, to + perform the destination port mapping lookup to translate and forward + this packet to device A at address and port 10.0.0.2:80. + +4.3.5 Non UDP/TCP Transport Traffic + + Any communication over transport protocols other than TCP and UDP + will not be served by this protocol. Examples are Generic Routing + Encapsulation (GRE), Authentication Header (AH) and Encapsulating + Security Payload (ESP). + +4.4 Long Term Solution + + As IPv6 is deployed, clients of this protocol supporting IPv6 will be + able to bypass this protocol and the NAT when communicating with + other IPv6 devices. In order to ensure this transition, any client + implementing this protocol SHOULD also implement IPv6 and use this + solution only when IPv6 is not available to both peers. + +4.5 Existing Deployed NATs + + Existing deployed NATs will not support this protocol. This protocol + will only work with NATs that are upgraded to support it. + + + + + + + + + + +Expires 14th March 2007 Cheshire, et al. [Page 16] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + +5. Security Considerations + + As discussed in section 3.2 "Determining the Public Address", only + clients on the private side of the NAT may create port mappings, and + only on behalf of themselves. By using IP address spoofing, it's + possible for one client to delete the port mappings of another + client. It's also possible for one client to create port mappings on + behalf of another client. The best way to deal with this + vulnerability is to use IPSec [RFC 2401]. + + Since allowing incoming connections is often a policy decision, any + NAT gateway implementing this protocol SHOULD have an administrative + mechanism to disable it. + + Some people view the property that NATs block inbound connections as + a security benefit which is undermined by this protocol. The authors + of this document have a different point of view. In the days before + NAT, all hosts had unique public IP addresses, and had unhindered + ability to communicate with any other host on the Internet. When NAT + came along it broke this unhindered connectivity, relegating many + hosts to second-class status, unable to receive inbound connections. + This protocol goes some way to undo some of that damage. The purpose + of a NAT gateway should be to allow several hosts to share a single + address, not to simultaneously impede those host's ability to + communicate freely. Security is most properly provided by end-to-end + cryptographic security, and/or by explicit firewall functionality, as + appropriate. Blocking of certain connections should occur only as a + result of explicit and intentional firewall policy, not as an + accidental side-effect of some other technology. + + +6.

Deployment History + + NAT-PMP client software first became available to the public + through Apple's Darwin Open Source code in August 2004. + NAT-PMP implementations began shipping to end users in large + volumes (i.e. millions) with the launch of Mac OS X 10.4 Tiger + and Bonjour for Windows 1.0 in April 2005. + + + +Expires 14th March 2007 Cheshire, et al. [Page 17] + +Internet Draft NAT Port Mapping Protocol 14th September 2006 + + + The NAT-PMP client in Mac OS X 10.4 Tiger and Bonjour for Windows + exists as part of the mDNSResponder system service. When a client + advertises a service using Wide Area Bonjour [DNS-SD], and the + machine is behind a NAT-PMP-capable NAT gateway, then if the machine + is so configured, the mDNSResponder system service automatically uses + NAT-PMP to set up an inbound port mapping, and then records the + public IP address and port in the global DNS. Existing client + software using the existing Bonjour programming APIs [Bonjour] + gets this functionality automatically. The logic is that if client + software publishes its information into the global DNS via Wide Area + Bonjour service advertising, then it's reasonable to infer an + expectation that this information should be usable by the peers + retrieving it. Generally speaking, recording a private IP address + like 10.0.0.2 in the public DNS is completely pointless because that + address is not reachable from clients on the other side of the NAT + gateway. In the case of a home user with a single computer directly + connected to their Cable or DSL modem, with a single global IPv4 + address and no NAT gateway (a surprisingly common configuration), + publishing that IP address into the global DNS is useful because that + IP address is reachable. In contrast, a home user using a NAT gateway + to share a single global IPv4 address between several computers loses + this ability to receive inbound connections easily. This breaks many + peer-to-peer collaborative applications, like the multi-user text + editor SubEthaEdit [SEE]. Automatically creating the necessary + inbound port mappings helps remedy this unintended side-effect of + NAT. + + The server side of the NAT-PMP protocol is implemented in Apple's + "AirPort Extreme" and "AirPort Express" wireless base stations. + + +9.
