tcpdump is a handy little library which provides a packet filtering mechanism based on the BSD packet filter (BPF).
Most notably, tcpdump needs this to work, and there is also a perl module (still in beta) which can use this as well. In plain english, if you want to write your own network traffic analyzer, this is the place to start.
