I'm planning something related, using Perl, a few modules from CPAN. (Net::PcapUtils, NetPacket::Ethernet, NetPacket::IP, NetPacket::UDP, NetPacket::TCP and Time::HiRes). The Perl script grabs traffic directly from libpcap (what tcpdump uses) and then writes it into a plain text file for further processing by a second script. http://www.mellon-collie.net/mycrap/grab-libpcap.txt for a bit of code (although you should note I'm not bothered about good code in this - just the right answer at the end of it all). Hope this helps. -- NAME : Adam Allen.
