pcap is a pretty standard library. Check out http://search.cpan.org/dist/Net-Pcap/Pcap.pm(view the samples!), http://perlmonks.org/?node_id=170648, and www.tcpdump.org. If you are just beginning, use tcpdump to capture "everything" to a file, and start playing. Later, when you know what you're doing, move to processing live captures. JJ	[reply]

Get wireshark (former ethereal), a Network Protocol Analyzer. On that website, there's a FAQ and plenty of Documentation. For in depth knowledge read TCP/IP Illustrated. --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.
