It is fine to run a sniffer on your own lan, but larger systems, like
university lans, usually consider a promiscuous ethernet port, which
is key to sniffing, as network abuse. You are likely to get kicked
off, or worse.

For diagnostic sniffing, using Linux, I am partial to Ethereal, which
is mostly a graphic front end to tcpdump. It can be set to trace
specific protocols, which gives it very similar capabilities, although
not as user friendly.
