6.12.03 10:46 Application Layer Packet Classifier for Linux 0.4.0 ( , , , )

Linux:
many great improvements:

  • connection tracking of FTP, IRC, etc...
  • distinguish between child/parent connection (FTP, IRC-DCC..)
  • patch together data from multiple packets
  • 52 protocols (most file sharing tools, still missing, IMHO: VoIP), 8 file types (PDF, Ogg, rpm...) and 2 worms (Nimda, Code Red)

For those who don't now l7-filter: l7-filter is a packet classifier (and QoS) which can be used as rule in iptables (blocking, bandwidth restriction, . Rule sample: -m layer7 --l7proto [http|ftp|etc...]
Packets are recognized using regular expression patterns. Many protocols are supported, but the wanted list is still very long
Great, isn't it?
