here's how to be snoopy:

tcpdump -i eth0
tcpdump -i eth0 udp
tcpdump -i eth0 tcp
tcpdump -i eth0 tcp port 119
tcpdump -i eth0 udp port 119

you can get port numbers from /etc/services or google.

i think i got all this right.  when you look at man tcpdump, you realize
that it's an incredibly complicated tool...
