+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ 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.)
+\f
+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.
+\f
+ 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.
+\f
+ 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
+\f
+ 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.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ 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.
+
+ <signature of Ty Coon>, 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.

+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ 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, 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.

+Installation instructions may be found in the INSTALL file.
+
+tinc is Copyright (C) 1998,99 Ivo Timmermans <zarq@iname.com> and
+others. For a complete list of authors see the AUTHORS file.

+
+This version of tinc relies on the GNU Multi-Precision Library
+(gmp). This library is available from your nearest GNU mirror. Please
+install this first even before trying to run configure. If you don't
+do this, configure will (hopefully) mention it to you.
+
+This version of tinc supports multiple virtual networks at once. To
+use this feature, you may supply a netname via the -n or --net
+options. The standard locations for the config files will then be
+/etc/tinc/<net>/.
+
+In this version, MAC addresses are stripped off before encoding and
+sending a packet. When the packet reaches its destination, the MAC
+addresses are rebuilt again. They then have the form
+FE:FD:aa:bb:cc:dd. aa, bb, cc and dd are taken from the destination
+and source IP address.
+
+tincd regenerates its encryption key pairs. It does this on the first
+activity after the keys have expired. This period is adjustable in the
+configuration file, and the default time is 3600 seconds (one
+hour). If you send a USR2 signal to the daemon, it'll regenerate
+immediately.

+This Eric Young's blowfish implementation, taken from his SSLeay library
+and made available as a separate library.
+
+The version number (0.7.2m) is the SSLeay version that this library was
+taken from.
+
+To build, just unpack and type make.
+If you are not using gcc, edit the Makefile.
+If you are compiling for an x86 box, try the assembler (it needs improving).
+There are also some compile time options that can improve performance,
+these are documented in the Makefile.

+
+This is a quick packaging up of my blowfish code into a library.
+It has been lifted from SSLeay.
+The copyright notices seem a little harsh because I have not spent the

+
+Basically if you just want to play with the library, not a problem.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+%
+% For those who want to use more than one line's worth of words in
+% the preamble, break the line within one argument and it
+% will parse correctly, i.e.,
+%
+% @multitable {Column 1 template} {Column 2 template} {Column 3
+% template}
+% Not:
+% @multitable {Column 1 template} {Column 2 template}
+% {Column 3 template}
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab, @multitable or @end multitable do not need to be on their
+% own lines, but it will not hurt if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab

+
+tinc is a Virtual Private Network (VPN) daemon that uses tunneling and
+encryption to create a secure private network between hosts on the
+Internet.
+
+Because the tunnel appears to the IP level network code as a normal
+network device, there is no need to adapt any existing software.
+
+This tunneling allows VPN sites to share information with eachother
+over the Internet without exposing any information to others.
+
+This document is the manual for tinc. Included are chapters on how to
+configure your computer to use tinc, as well as the configuration
+process of tinc itself.

+@section Virtual Private Networks
+
+A Virtual Private Network or VPN is a network that can only be accessed
+by a few elected computers that participate. 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 <itimmermans@@bigfoot.com>
+@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 from the manpage
+
+It is perfectly ok for you to run more than one tinc daemon.
+However, in its default form, you will soon notice that you can't use
+two different configuration files without the -c option.
+
+We have thought of another way of dealing with this: network names. 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 it sees a `ConnectTo' value in the file, it will
+try to connect to it, on the given port. If this fails, tinc exits.
+
+
+@c ==================================================================
+@node Configuration file, Example, How connections work, Configuring tinc
+@section Configuration file
+
+The actual configuration of the daemon is done in the file
+@file{/etc/tinc/nn/tincd.conf}.
+
+This file consists of comments (lines started with a #) or assignments
+in the form of
+
+@example
+Variable = Value.
+@end example
+
+The variable names are case insensitive, and any spaces, tabs, newlines
+and carriage returns are ignored. Note: it is not required that you put
+in the `=' sign, but doing so improves readability. If you leave it
+out, remember to replace it with at least one space character.
+
+@menu
+* Variables::
+@end menu
+
+@c ==================================================================
+@node Variables, , Configuration file, Configuration file
+@subsection Variables
+
+Here are all valid variables, listed in alphabetical order:
+
+@c straight from the manpage
+@table @asis
+@item AllowConnect = (yes|no)
+If set to yes, anyone may try to connect to you. 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. Please see the manpage for genauth(8) for more information
+about passphrases as used by tinc.
+
+@item PingTimeout = number
+The number of seconds of inactivity that tinc will wait before sending a
+probe to the other end. If that other end doesn't answer within that
+same amount of seconds, the connection is terminated, and the others
+will be notified of this.
+
+@item TapDevice = device
+The ethertap device to use. Note that you can only use one device per
+daemon. The info pages of the tinc package contain more information
+about configuring an ethertap device for linux.
+
+@end table
+
+
+@c ==================================================================
+@node Example, , Configuration file, Configuring tinc
+@section Example
+
+Imagine the following situation. An A-based company wants to connect
+three branch offices in B, C and D using the internet. All four offices
+have a 24/7 connection to the internet.
+
+A is going to serve as the center of the network. B and C will connect
+to A, and D will connect to C. Each office will be assigned their own IP
+network, 10.x.0.0.
+
+@example
+A: net 10.1.0.0 mask 255.255.0.0 gateway 10.1.54.1 internet IP 1.2.3.4
+B: net 10.2.0.0 mask 255.255.0.0 gateway 10.2.1.12 internet IP 2.3.4.5
+C: net 10.3.0.0 mask 255.255.0.0 gateway 10.3.69.254 internet IP 3.4.5.6
+D: net 10.4.0.0 mask 255.255.0.0 gateway 10.4.3.32 internet IP 4.5.6.7
+@end example
+
+``gateway'' is the VPN IP address of the machine that is running the
+tincd. ``internet IP'' is the IP address of the firewall, which does not
+need to run tincd, but it must do a port forwarding of TCP&UDP on port
+655 (unless otherwise configured).e
+
+In this example, it is assumed that eth0 is the interface that points to
+the inner LAN of the office. This could be the same as the interface
+that leads to the internet.
+
+@subsubheading For A
+
+@emph{A} would be configured like this:
+
+@example
+ifconfig tap0 hw ether fe:fd:0a:01:36:01
+ifconfig tap0 10.1.54.1 netmask 255.0.0.0
+ifconfig eth0 10.1.54.1 netmask 255.255.0.0 broadcast 10.1.255.255
+@end example
+
+and in /etc/tinc/tincd.conf:
+
+@example
+TapDevice = /dev/tap0
+MyVirtualIP = 10.1.54.1/16
+@end example
+
+@subsubheading For B
+
+@example
+ifconfig tap0 hw ether fe:fd:0a:02:01:0c
+ifconfig tap0 10.2.1.12 netmask 255.0.0.0
+ifconfig eth0 10.2.43.8 netmask 255.255.0.0 broadcast 10.2.255.255
+@end example
+
+and in /etc/tinc/tincd.conf:
+
+@example
+TapDevice = /dev/tap0
+MyVirtualIP = 10.2.1.12/16
+ConnectTo = 1.2.3.4
+AllowConnect = no
+@end example
+
+Note here that the internal address (on eth0) doesn't have to be the
+same as on the tap0 device. Also, ConnectTo is given so that no-one can
+connect to this node.
+
+@subsubheading For C
+
+@example
+ifconfig tap0 hw ether fe:fd:0a:03:45:fe
+ifconfig tap0 10.3.69.254 netmask 255.0.0.0
+ifconfig eth0 10.3.69.254 netmask 255.255.0.0 broadcast 10.3.255.255
+@end example
+
+and in /etc/tinc/A/tincd.conf:
+
+@example
+MyVirtualIP = 10.3.69.254/16
+ConnectTo = 1.2.3.4
+ListenPort = 2000
+@end example
+
+C already has another daemon that runs on port 655, so they have to
+reserve another port for tinc. They also use the netname to distinguish
+between the two. tinc is started with `tincd -n A'.
+
+@subsubheading For D
+
+@example
+ifconfig tap0 hw ether fe:fd:0a:04:03:20
+ifconfig tap0 10.4.3.32 netmask 255.0.0.0
+ifconfig tap0 10.4.3.32 netmask 255.255.0.0 broadcast 10.4.255.255
+@end example
+
+and in /etc/tinc/tincd.conf:
+
+@example
+MyVirtualIP = 10.4.3.32/16
+ConnectTo = 3.4.5.6
+ConnectPort = 2000
+AllowConnect = no
+@end example
+
+D will be connecting to C, which has a tincd running for this network on
+port 2000. Hence they need to put in a ConnectPort.
+
+@subsubheading Authentication
+
+A, B, C and D all generate a passphrase with genauth 2048, the output is
+stored in /etc/tinc/passphrases/local, except for C, where it should be
+/etc/tinc/A/passphrases/local.
+
+A stores a copy of B's passphrase in /etc/tinc/passphrases/10.2.0.0
+
+A stores a copy of C's passphrase in /etc/tinc/passphrases/10.3.0.0
+
+B stores a copy of A's passphrase in /etc/tinc/passphrases/10.1.0.0
+
+C stores a copy of A's passphrase in /etc/tinc/A/passphrases/10.1.0.0
+
+C stores a copy of D's passphrase in /etc/tinc/A/passphrases/10.4.0.0
+
+D stores a copy of C's passphrase in /etc/tinc/passphrases/10.3.0.0
+
+@subsubheading Starting
+
+A has to start their tincd first. Then come B and C, where C has to
+provide the option `-n A', because they have more than one tinc
+network. Finally, D's tincd is started.
+

+@c ==================================================================
+@node Managing keys, Runtime options, Running tinc, Running tinc
+@section Managing keys
+
+Before attempting to start tinc, you have to create passphrases. 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.

+

+computer over the existing Internet infrastructure.

+@subsection A preview of the way the tinc works
+
+@cindex ethertap
+@cindex frame type
+The data itself is read from a character device file, the so-called
+@emph{ethertap} device. 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.

+@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.

+.TH TINC 5 "March 1999" "tinc version 0.2.16" "FSF"
+.SH NAME
+tincd.conf \- tinc daemon configuration
+.SH "DESCRIPTION"
+The files in the \fI/etc/tinc\fR directory contain runtime and
+security information for the \fBtinc\fR(8) daemon.
+.PP
+.SH "NETWORKS"
+It is perfectly ok for you to run more than one tinc daemon. However,
+in its default form, you will soon notice that you can't use two
+different configuration files without the \fI-c\fR option.
+
+We have thought of another way of dealing with this: network
+names. This means that you call \fBtincd\fR with the \fI-n\fR argument,
+which will assign a name to this daemon.
+
+The effect of this is that the daemon will set its configuration
+``root'' to \fI/etc/tinc/\fBnn\fI/\fR, where \fBnn\fR is your argument
+to the \fI-n\fR option. You'll notice that it appears in syslog as
+``tincd.\fBnn\fR''.
+
+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 \fI/etc/tinc/\fR,
+instead of \fI/etc/tinc/\fBnn\fI/\fR; the configuration file should be
+\fI/etc/tinc/tincd.conf\fR, and the passphrases are now expected to be
+in \fI/etc/tinc/passphrases/\fR.
+
+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.
+.PP
+.SH "PASSPHRASES"
+You should use the \fBgenauth\fR(8) program to generate passphrases.
+with, it accepts a single parameter, which is the number of bits the
+passphrase should be. Its output should be stored in
+\fI/etc/tinc/\fBnn\fI/passphrases/local\fR \-\- where \fBnn\fR stands
+for the network (See under \fBNETWORKS\fR) above.
+
+Please see the manpage for \fBgenauth\fR to learn more about setting
+up an authentication scheme.
+.PP
+.SH "CONFIGURATION"
+The actual configuration of the daemon is done in the file
+\fI/etc/tinc/\fBnn\fI/tincd.conf\fR.
+
+This file consists of comments (lines started with a \fB#\fR) or
+assignments in the form of
+.PP
+.Vb 1
+\& \fIVariable \fB= \fIValue\fR.
+.Ve
+.PP
+The variable names are case insensitive, and any spaces, tabs,
+newlines and carriage returns are ignored. \fINote\fR: it is not
+required that you put in the \fB=\fR sign, but doing so improves
+readability. If you leave it out, remember to replace it with at least
+one space character.
+.PP
+.SH "VARIABLES"
+.PP
+Here are all valid variables, listed in alphabetical order:
+.TP
+\fBAllowConnect = \fB(\fIyes\fB|\fIno\fB)\fR
+If set to \fIyes\fR, anyone may try to connect to you. If you set this
+to no, no incoming connections will be accepted. This does not affect
+the outgoing connections.
+.TP
+\fBConnectPort = \fIport\fR
+Connect to the upstream host (given with the \fBConnectTo\fR
+directive) on port \fIport\fR. \fIport\fR may be given in decimal
+(default), octal (when preceded by a single zero) or hexadecimal
+(prefixed with \fB0x\fR). \fIport\fR is the port number for both the
+UDP and the TCP (meta) connections.
+.TP
+\fBConnectTo = \fB(\fIIP address\fB|\fIhostname\fB)\fR
+Specifies which host to connect to on startup. If the
+\fBConnectPort\fR variable is omitted, then tinc will try to connect
+to port 655.
+
+If you don't specify a host with \fBConnectTo\fR, tinc won't connect
+at all, and will instead just listen for incoming connections. Only
+the initiator of a tinc VPN should need this.
+.TP
+\fBKeyExpire = \fIs\fR
+The secret (and public) key expires after \fIs\fR seconds. The default
+is 3600 seconds, or one hour.
+
+If you make it shorter, a lot of time and bandwidth is spent
+negotiating over the new keys. If you make it longer, you make
+yourself more vulnerable to crackers, because they have more data to
+work with. The best value depends on the speed of the link, and the
+amount of data that goes over it.
+.TP
+\fBListenPort = \fIport\fR
+Listen on local port \fIport\fR. The computer connecting to this
+daemon should use this number as the argument for his
+\fBConnectPort\fR. Again, the default is 655.
+.TP
+\fBMyOwnVPNIP = \fInetwork address\fR[\fB/\fImaskbits\fR]
+The \fInetwork address\fR 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.
+
+\fImaskbits\fR is the number of bits set to 1 in the netmask part.
+.TP
+\fBMyVirtualIP = \fInetwork address\fR[\fB/\fImaskbits\fR]
+This is an alias for \fBMyOwnVPNIP\fR.
+.TP
+\fBPassphrases = \fIdirectory\fR
+The directory where tinc will look for passphrases when someone tries
+to cennect. Please see the manpage for \fBgenauth\fR(8) for more
+information about passphrases as used by tinc.
+.TP
+\fBPingTimeout = \fInumber\fR
+The number of seconds of inactivity that tinc will wait before sending
+a probe to the other end. If that other end doesn't answer within that
+same amount of seconds, the connection is terminated, and the others
+will be notified of this.
+.TP
+\fBTapDevice = \fIdevice\fR
+The ethertap device to use. Note that you can only use one device per
+daemon. The info pages of the tinc package contain more information
+about configuring an ethertap device for linux.
+.PP
+.SH "FILES"
+.TP
+\fI/etc/tinc/\fR
+The top directory for configuration files.
+.TP
+\fI/etc/tinc/\fBnn\fI/tincd.conf\fR
+The default name of the configuration file for net
+\fBnn\fR.
+.TP
+\fI/etc/tinc/\fBnn\fI/passphrases/\fR
+Passphrases are kept in this directory. (See the section
+\fBPASSPHRASES\fR above).
+.PP
+.SH "SEE ALSO"
+\fBtincd\fR(8), \fBgenauth\fR(8)

+/* alloca.c -- allocate automatically reclaimed memory
+ (Mostly) portable public-domain implementation -- D A Gwyn
+
+ This implementation of the PWB library alloca function,
+ which is used to allocate space off the run-time stack so
+ that it is automatically reclaimed upon procedure exit,
+ was inspired by discussions with J. Q. Johnson of Cornell.
+ J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+ There are some preprocessor constants that can
+ be defined when compiling for your specific system, for
+ improved efficiency; however, the defaults should be okay.
+
+ The general concept of this implementation is to keep
+ track of all alloca-allocated blocks, and reclaim any
+ that are found to be deeper in the stack than the current
+ invocation. This heuristic does not reclaim storage as
+ soon as it becomes invalid, but it will do so eventually.
+
+ As a special case, alloca(0) reclaims storage without
+ allocating any. It is a good idea to use alloca(0) in
+ your main control loop, etc. to force garbage collection. */
