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
  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 ​libnfnetlink 0.0.39 and ​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
