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
