GNU Carnivore With Perl Data Lookup
Kallahar writes: "Inspired by the FBI's DCS1000: Carnivore is a networked art project in two parts. The first part is Carnivore Server, an application which performs packet-sniffing on a specific local area network and serves the resulting data stream via the net. The second part consists of an unlimited number of client applications which tap into this data stream and interpret it in creative ways."
Carnivore Server is a set of Perl scripts running on top of tcpdump
You know, sadly, this is probably far more sophisticated than the actual Carnivore system.
Good grief.
