= Work In Progress about ULOG support in Vuurmuur =

There is a branch for ulog support in subversion. To get these sources use the following command:
 svn co https://vuurmuur.svn.sourceforge.net/svnroot/vuurmuur/branches/nflog vuurmuur_nflog

Just some thoughts about how to implement ulog support in Vuurmuur.

 * Create a config item in /etc/vuurmuur/config.conf[[BR]]
 This will be LOGMETHOD, which can have the following values:
  * log - for syslog logging
  * ulog - for ulog logging, which has to be enabled during compilation
 * Let ./configure check if libnetfilter_log is available, only then it should be used

== Installing dependancies for ulog support ==
You have to install [http://www.netfilter.org/projects/libnfnetlink/index.html libnfnetlink 0.0.39] and [http://www.netfilter.org/projects/libnetfilter_log/index.html libnetfilter_log 0.0.14] to be able to use ulog with vuurmuur.
When configuring libnfnetlink and libnetfilter you might want to supply extra options to the configure command.
{{{
./configure --prefix=/usr
}}}
When you don't do this, you have to add the default install path of the library to the {{{PKG_CONFIG_PATH}}} and {{{LD_LIBRARY_PATH}}}
{{{
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
}}}
