By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 00000000..e6a85edb --- /dev/null +++ b/ChangeLog @@ -0,0 +1,623 @@ +2000-02-07 Guus Sliepen + + * Version 0.3.3 + + * src/net.c: fixed add_mac_addresses to work with the latest + kernels.

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, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + 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 at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' 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. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. 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. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +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 must use a version of `make' that +supports the `VPATH' variable, such as 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 `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have 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' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' 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' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +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 host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +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. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--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. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 00000000..0ea29c83 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,10 @@ +## Process this file with automake to get Makefile.in + +AUTOMAKE_OPTIONS = gnits + +SUBDIRS = m4 lib cipher src doc + +ACLOCAL_AMFLAGS = -I m4 + +EXTRA_DIST = TODO + diff --git a/NEWS b/NEWS new file mode 100644 index 00000000..290f59fd --- /dev/null +++ b/NEWS @@ -0,0 +1,115 @@ +version 0.3.4 Feb 19 2000 + * The fix that was in 0.3.3 appeared to be wrong.

This goal is achievable in +more than just one way. + +@cindex private +For instance, a VPN can consist of a single standalone ethernet LAN. Or +even two computers hooked up using a nullmodem cable@footnote{Though +discussable, I think it qualifies as a VPN.}. In these cases, it is +obvious that the network is @emph{private}. But there is another type +of VPN, the type tinc was made for. + +@cindex virtual +tinc uses normal IP datagrams to encapsulate data that goes over the VPN +network link. In this case it's also clear that the network is +@emph{virtual}, because no direct network link has to exist between to +participants. + +As is the case with either type of VPN, anybody could eavesdrop. Or +worse, alter data. Hence it's probably advisable to encrypt the data +that flows over the network. + +` +@c ================================================================== +@node tinc, , VPNs, Introduction +@section tinc + +I really don't quite remember what got us started, but it must have been +Guus' idea. He wrote a simple implementation (about 50 lines of C) that +used the @emph{ethertap} device that linux knows of since somewhere +about kernel 2.1.60. It didn't work immediately and he improved it a +bit. At this stage, the project was still simply called @samp{vpnd}. + +Since then, a lot has changed---to say the least. + +@cindex tincd +tinc now supports encryption, it consists of a single daemon (tincd) for +both the receiving and sending end, it hase becom largely +runtime-configurable---in short, it has become a full-fledged +professional package. + +A lot can---and will be---changed. I have a few things that I'd like to +see in the future releases of tinc. Not everything will be available in +the near future. Our first objective is to make tinc work perfectly as +it stands, and then add more advanced features. + +Meanwhile, we're always open-minded towards new ideas. And we're +available too. + + +@c ================================================================== +@node Configuring a Linux system, Installing tinc, Introduction, Top +@chapter Configuring a Linux system + +This chapter contains information on how a Linux system is configured +for the use of tinc. + +@menu +* Configuring the kernel:: +* Files Needed:: +* Setting up the devices:: +@end menu + + +@c ================================================================== +@node Configuring the kernel, Files Needed, Configuring a Linux system, Configuring a Linux system +@section Configuring the kernel + +Since this particular implementation only runs on 2.1 or higher Linux +kernels, you should grab one (2.2 is current at this time). A 2.0 port +is not really possible, unless someone tells me someone ported the +ethertap and netlink devices back to 2.0. + +If you are unfamiliar with the process of configuring and compiling a +new kernel, you should read the +@uref{http://howto.linuxberg.com/LDP/HOWTO/Kernel-HOWTO.html, Kernel +HOWTO} first. Do that now! + +Here are the options you have to turn on/off when configuring a new +kernel. + +@example +Code maturity level options +[*] Prompt for development and/or incomplete code/drivers +Networking options +[*] Kernel/User netlink socket +<*> Netlink device emulation +Network device support +<*> Ethertap network tap +@end example + +Any other options not mentioned here are not relevant to tinc. If you +decide to build any of these as dynamic kernel modules, it's a good idea +to add these lines to @file{/etc/modules.conf}. + +@example +alias tap0 ethertap +alias char-major-36 netlink_dev +@end example + +Finally, after having set up other options, build the kernel and boot +it. Unfortunately it's not possible to insert these modules in a running +kernel. + + +@c ================================================================== +@node Files Needed, Setting up the devices, Configuring the kernel, Configuring a Linux system +@section Files Needed + +@subsubheading Device files + +First, you'll need the special device file(s) that form the interface +between the kernel and the daemon. + +@example +mknod -m 600 /dev/tap0 c 36 16 +chown 0.0 /dev/tap0 +@end example + +The permissions now will be such that only the super user may read/write +to this file. You'd want this, because otherwise eavesdropping would +become a tad too easy. This does, however, imply that you'd have to run +tincd as root. + +If you want to, you may also create more device files, which would be +numbered 0...15, with minor device numbers 16...31. They all should be +owned by root and have permission 600. + + +@subsubheading @file{/etc/networks} + +You may add a line to @file{/etc/networks} so that your vpn will get a +symoblic name. For example: + +@example +myvpn 10.0.0.0 +@end example + + +@subsubheading @file{/etc/services} + +You may add this line to @file{/etc/services}. The effect is that you +may supply a @samp{vpn} as a valid port number to some programs. The +number 655 is registered with the IANA. + +@example +tinc 655/tcp TINC +tinc 655/udp TINC +# Ivo Timmermans +@end example + + +@c ================================================================== +@node Setting up the devices, , Files Needed, Configuring a Linux system +@section Setting up the devices + +Before you can start transmitting data over the tinc tunnel, you must +set up the ethertap network devices. + +First, decide which IP addresses you want to have associated with these +devices, and what network mask they must have. You also need these +numbers when you are going to configure tinc itself. @xref{Configuring +tinc}. + +It doesn't matter much which part you do first, setting up the network +devices or configure tinc. But they both have to be done before you try +to start a tincd. + +The actual setup of the ethertap device is quite simple, just repeat +after me: + +@example +ifconfig tap@emph{n} hw ether fe:fd:@emph{xx}:@emph{xx}:@emph{xx}:@emph{xx} +@end example + +The @emph{n} here is the number of the ethertap device you want to +use. It should be the same @emph{n} as the one you use for +@file{/dev/tap@emph{n}}. The @emph{xx}s are four hexadecimal numbers +(0--ff). With previous versions of tincd, it didn't matter what they +were. But newer kernels require properly set up ehternet addresses. +In fact, the old behaviour was wrong. It is required that the @emph{xx}s +match MyOwnVPNIP. + +@example +ifconfig tap@emph{n} @emph{IP} netmask @emph{mask} +@end example + +This will activate the device with an IP address @emph{IP} with network +mask @emph{mask}. + + + +@c ================================================================== +@node Installing tinc, Configuring tinc, Configuring a Linux system, Top +@chapter Installing tinc + +First download it.

This +means that you call tincd with the -n argument, which will assign a name +to this daemon. + +The effect of this is that the daemon will set its configuration +``root'' to /etc/tinc/nn/, where nn is your argument to the -n +option. You'll notice that it appears in syslog as ``tincd.nn''. + +However, it is not strictly necessary that you call tinc with the -n +option. In this case, the network name would just be empty, and it will +be used as such. tinc now looks for files in /etc/tinc/, instead of +/etc/tinc/nn/; the configuration file should be /etc/tinc/tincd.conf, +and the passphrases are now expected to be in /etc/tinc/passphrases/. + +But it is highly recommended that you use this feature of tinc, because +it will be so much clearer whom your daemon talks to. Hence, we will +assume that you use it. + + +@c ================================================================== +@node How connections work, Configuration file, Multiple networks, Configuring tinc +@section How connections work + +Before going on, first a bit on how tinc sees connections. + +When tinc starts up, it reads in the configuration file and parses the +commandline options.

If you set this to no, +no incoming connections will be accepted. This does not affect the +outgoing connections. + +@item ConnectPort = port +Connect to the upstream host (given with the ConnectTo directive) on +port port. port may be given in decimal (default), octal (when preceded +by a single zero) or hexadecimal (prefixed with 0x). port is the port +number for both the UDP and the TCP (meta) connections. + +@item ConnectTo = (IP address|hostname) +Specifies which host to connect to on startup. If the ConnectPort +variable is omitted, then tinc will try to connect to port 655. + +If you don't specify a host with ConnectTo, regardless of whether a +value for ConnectPort is given, tinc won't connect at all, and will +instead just listen for incoming connections. Only the initiator of a +tinc VPN should need this. + +@item ListenPort = port +Listen on local port port. The computer connecting to this daemon should +use this number as the argument for his ConnectPort. Again, the +default is 655. + +@item MyOwnVPNIP = local address[/maskbits] +The local address is the number that the daemon will propagate to +other daemons on the network when it is identifying itself. Hence this +will be the file name of the passphrase file that the other end expects +to find the passphrase in. + +The local address is the IP address of the tap device, not the real IP +address of the host running tincd. Due to changes in recent kernels, it +is also necessary that you make the ethernet (also known as MAC) address +equal to the IP address (see the example). + +maskbits is the number of bits set to 1 in the netmask part. + +@item MyVirtualIP = local address[/maskbits] +This is an alias for MyOwnVPNIP. + +@item Passphrases = directory +The directory where tinc will look for passphrases when someone tries to +cennect.

When +tinc tries to make a connection, it exchanges some sensitive +data. Before doing so, it likes to know if the other end is +trustworthy. + +To do this, both ends must have some knowledge about the other. In the +case of tinc this is the authentication passphrase. + +This passphrase is a number, which is chosen at random. This number is +then sent to the other computers which want to talk to us directly. To +avoid breaking security, this should be done over a known secure channel +(such as ssh or similar). + +All passphrases are stored in the passphrases directory, which is +normally /etc/tinc/nn/passphrases/, but it may be changed using the +`Passphrases' option in the config file. + +To generate a passphrase, run `genauth'. genauth takes one argument, +which is the length of the passphrase in bits. The length of the +passphrase should be in the range 1024--2048 for a key length of 128 +bits. genauth creates a random number of the specified length, and puts +it to stdout. + +Every computer that wants to participate in the VPN should do this, and +store the output in the passphrases directory, in the file @file{local}. + +When every computer has his own local key, it should copy it to the +computer that it wants to talk to directly. (i.e. the one it connects to +during startup.) This should be done via a secure channel, because it is +sensitive information. If this is not done securely, someone might break +in on you later on. + +Those non-local passphrase files must have the name of the VPN IP +address that they will advertise to you. For instance, if a computer +tells us it likes to be 10.1.1.3 with netmask 255.255.0.0, the file +should still be called 10.1.1.3, and not 10.1.0.0. + + +@c ================================================================== +@node Runtime options, , Managing keys, Running tinc +@section Runtime options + +Besides the settings in the configuration file, tinc also accepts some +command line options. + +This list is a longer version of that in the manpage.

This device is associated with a network +interface. Any data sent to this interface can be read from the device, +and any data written to the device gets sent from the interface. Data to +and from the device is formatted as if it were a normal ethernet card, +so a frame is preceded by two MAC addresses and a @emph{frame type} +field. + +So when tinc reads an ethernet frame from the device, it determines its +type. Right now, tinc can only handle Internet Protocol version 4 (IPv4) +frames. Plans to support other protocols are being made. When tinc knows +which type of frame it has read, it can also read the source and +destination address from it. + +Now it is time that the frame gets encrypted. Currently the only +encryption algorithm available is blowfish. + +@cindex encapsulating +When the encryption is ready, time has come to actually transport the +packet to the destination computer. We do this by sending the packet +over an UDP connection to the destination host. This is called +@emph{encapsulating}, the VPN packet (though now encrypted) is +encapsulated in another IP datagram. + +When the destination receives this packet, the same thing happens, only +in reverse. So it does a decrypt on the contents of the UDP datagram, +and it writes the decrypted information to its own ethertap device. + + +@c ================================================================== +@node The Meta-connection, , Protocol Preview, The Connection +@subsection The meta-connection + +Having only a UDP connection available is not enough. Though suitable +for transmitting data, we want to be able to reliably send other +information, such as routing and encryption information to somebody. + +TCP is a better alternative, because it already contains protection +against information being lost, unlike UDP. + +So we establish two connections. One for the encrypted VPN data, and one +for other information, the meta-data. Hence, we call the second +connection the meta-connection. We can now be sure that the +meta-information doesn't get lost on the way to another computer. + +@cindex data-protocol +@cindex meta-protocol +Like with any communication, we must have a protocol, so that everybody +knows what everything stands for, an how he should react. Because we +have two connections, we also have two protocols. The protocol used for +the UDP data is the ``data-protocol,'' the other one is the +``meta-protocol.'' + + +@c ================================================================== +@node Security, The Protocol, The Connection, Technical information +@section About tinc's encryption and other security-related issues. + +@cindex tinc +@cindex Cabal +tinc got its name from ``TINC,'' short for @emph{There Is No Cabal}; the +alleged Cabal was/is an organization that was said to keep an eye on the +entire Internet. As this is exactly what you @emph{don't} want, we named +the tinc project after TINC. + +@cindex SVPN +But in order to be ``immune'' to eavesdropping, you'll have to encrypt +your data. Because tinc is a @emph{Secure} VPN (SVPN) daemon, it does +exactly that: encrypt. + +This chapter is a mixture of ideas, reasoning and explanation, please +don't take it too serious. + +@menu +* Encryption:: +* Key Management:: +* Authentification:: How to be sure we're talking to the right person +* Protection:: +@end menu + + +@c ================================================================== +@node Encryption, Key Management, Security, Security +@subsection Encryption + +Encryption algorithms come in lots of flavors, most of which are not +safe enough to use on the Internet, if at all. Algorithms that we've +considered using are: RSA, blowfish, twofish and IDEA. + +@itemize @bullet +@item +@cindex RSA +@emph{RSA} is patented. A fee must be paid if you use it, so it can't +be used in an Open Source program. + +@item +@cindex blowfish +@emph{blowfish} was the standard encryption method at least up to version +0.2.23, but as Dekan pointed out, it may not be all that secure. It is +also patented, but it may be used freely. + +@item +@cindex twofish +@emph{twofish} should be better, but i've not seen a useable +ready-to-use implementation somewhere out of the US. I'll remember this +as a future encryption method. + +@item +@cindex IDEA +@emph{IDEA} is patented, and free for non-commercial use. It is going to +be the standard encryption method. + +@end itemize + +You may choose any of the last three encryption methods in tinc. Please +note, however, that ALL computers on your VPN must currenttly use the +same. This should (among other things) be more flexible, tinc could for +instance load a new encryption library the minute it is needed. + + +@c ================================================================== +@node Key Management, Authentification, Encryption, Security +@subsection Key Management +@c FIXME: recheck + +@cindex Diffie-Hellman +You can't just send a private encryption key to your peer, because +somebody else might already be listening to you. So you'll have to +negotiate over a shared but secret key. One way to do this is by using +the ``Diffie-Hellman key exchange'' protocol +(@uref{http://www.rsa.com/rsalabs/faq/html/3-6-1.html}). The idea is as +follows. + +You have two participants A and B that want to agree over a shared +secret encryption key. Both parties have some large prime number p and a +generator g. These numbers may be known to the outside world, and hence +may be included in the source distribution. + +@cindex secret key +Both parties then generate a secret key. A generates a, and computes g^a +mod p. This is then sent to B; while B computes g^b mod p, and transmits +this to A, b being generated by B. Both a and b must be smaller than +p-1. + +These private keys are generated upon startup, and they are not changed +while the connection exists. A possible feature in the future is to +dynamically change the keys, every hour for example. + +Both parties then calculate g^ab mod p = k. k is the new, shared, but +still secret key. + +To obtain a key k of a sufficient length (128 bits in our vpnd), p +should be 2^129-1 or more. + + +@c ================================================================== +@node Authentification, Protection, Key Management, Security +@subsection Authentification +@c FIXME: recheck + +@cindex man-in-the-middle attack +Because the Diffie-Hellman protocol is in itself vulnerable to the +``man-in-the-middle attack,'' we should introduce an authentification +system. + +We will let A transmit a passphrase that is also known to B encrypted +with g^a, before A sends this to B. This way, B can check whether A is +really A or just someone else. + +@cindex passphrase +This passphrase should be 2304 bits for a symmetric encryption +system. But since an asymmetric system is more secure, we could do with +2048 bits. This only holds if the passphrase is very random. + +These passphrases could be stored in a file that is non-readable by +anyone else but root; e.g. @file{/etc/vpn/passphrases}. + +The only thing that needs to be taken care of is how A announces its +passphrase to B. + + +@c ================================================================== +@node Protection, , Authentification, Security +@subsection Protecting your data + +Now we have securely hidden our data.
