An update to this site is really needed but in the mean time I proudly present my stab at linux kernel hacking. I ported the rtsp conntrack module to the new 2.6.20 netfilter API. I mostly did it because I need it to watch the Apple screencasts that appear every now and then.
So without much further ado I present the patch for the latest kernel releases.
NB: This code works for me, it might open a huge security hole on your firewall or kill your cat.
