Dependencies
============

Anytun can be built by using either libgcrypt, libnettle or the openssl-crypto
library. The latter is more performant in most cases but there are some license
issues when using this library.

Linux
-----
(this includes Debian with FreeBSD Kernel)

using libgcrypt:
  libgcrypt11-dev

using ssl crypto library:
  libssl-dev

using nettle crypto library:
  nettle-dev

common:
  build-essential
  libboost-serialization-dev
  libboost-thread-dev
  libboost-system-dev
  libboost-regex-dev

if you want to rebuild the manpage:
  asciidoc


Freebsd
-------

using libgcrypt:
   security/libgcrypt

using ssl crypto lib:
   <nothing here>

common:
   devel/boost (boost-libs on newer versions of the ports tree)
   devel/gmake

if you want to rebuild the manpage:
 textproc/asciidoc
 textproc/libxslt
 textproc/docbook-xsl
 sysutils/readlink
 misc/getopt



Windows
-------
OpenSSL
 Developer:
  http://www.slproweb.com/download/Win32OpenSSL-0_9_8j.exe

 Runtime Only:
  http://www.slproweb.com/download/Win32OpenSSL_Light-0_9_8j.exe

Boost 1.35:
  http://www.boostpro.com/download/boost_1_35_0_setup.exe

  As it can take some time to install everything from boost here is a
  complete list of libraries which have to be installed in order to build anytun:

   * Serialization
   * Thread
   * date_time
   * System
   * regex

Microsoft Visual C++ 2008 Redistributable Package (x86):
  http://www.microsoft.com/downloads/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF



Installation
============

Getting the source via subversion:
----------------------------------
svn co http://svn.anytun.org/anytun/trunk anytun
cd anytun

Building from source
--------------------

using libgcrypt:

 # cd src
 # ./configure
 # make

using ssl crypto library:

 # cd src
 # ./configure --use-ssl-crypto
 # make


Notes:
  - try './configure --help' for further information
  - if using openssl pre 0.9.8 you have to disable passphrase
    because openssl had no SHA256 implementation prior to this
    version
  - on FreeBSD you have to use gmake instead of make
  - the FreeBSD port has some issues concering daemonizing and signal handling

Installing
----------

# sudo make install

This will install anytun under the --prefix defined with configure.

Uninstalling
------------

# sudo make remove

This removes everything except for the config files

# sudo make purge

This also removes the config files



Usage:
======

init.d script
-------------

The init.d script can be used to start anytun at boot time. It searches for
configuration files which reside at $CONFIG_DIR. For each instance of anytun
which should be started there must be a directory containing at least a file
named config. This file must contain all command line parameter which should
be used when starting the daemon. One line for each parameter. Empty lines and
lines starting with # are ignored. Besides the config file there may be a script
named post-up.sh which will be called when the tun/tap device comes up.
Furthermore there may be a directory called conf.d containing config files for
anytun-config. The syntax of this files is quite the same as those for anytun.
These files are used to configure a multi connection setup using anytun-config
and anytun-controld
This is an example of how the script can be used to start anytun:

# /etc/init.d/anytun start client1 p2p-a

In this case the script will start 2 instances of anytun using the config files
$CONFIG_DIR/client1/config and $CONFIG_DIR/p2p-a/config.
If no instance name is specified the script will use the file $CONFIG_DIR/autostart
to determine which instances to start or stop. This file must contain a list
of instance names which should be used when no names are specified at the command
line. One line for each name. Empty lines and lines starting with # are ignored.



Errors:
=======

Note: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)
Cannot open TUN/TAP dev /dev/anytun0: No such file or directory (errno=2)

Solution: Enabling tun/tap device
------------------------------------

modprobe tun
cd /dev
./MAKEDEV tun

edit /etc/modules and add the line
tun
to load the module automatically
