Not to mention wireshark (formerly ethereal)! When I've got a tricky networking problem, I usually use tcpdump to do captures (on both sides of the connection when possible) then analyze them on my laptop using wireshark.

Use tcpdump to store full packets to file instead of displaying just the headers:

tcpdump -s0 -w <file> -i [ethN | any] [optional filter expression]
