Ethereal has extensive decodes, and the GUI can be useful.

Thanks for the replies - the old gray cells ain't what they used to be.

man tcpdump

Ethereal if you want a GUI. Tethereal if you want more detail than
tcpdump gives.

Those are just front-ends to tcpdump, and require knowledge of the tcpdump
command structure to produce any particularly-desired output. "man tcpdump"
is what the OP asked for.

Ethereal et. al. can read/write tcpdump format data. However they're
not "just front ends". Last time I looked they didn't even use libpcap.

You apparently have never installed and run [t]ethereal then.

I just didn't look hard enough. I thought that libwiretap had replaced
pcap for everything, but it seems that it hasn't (yet). I stand corrected.
