Yes, lsof seems nice.  It lists the process, the user, and other useful
information.  Open UDP sockets don't have "LISTEN" btw ('cause they're
not listening), but I could put up some shell scripts / aliases that do
the right grep'ing.  

Anyway, I find it a pity that this functionality (listing open sockets
with process+user) is not included in the base system.  I think it
should be.  It's the first thing I (want to) do on a fresh install (on
FreeBSD: sockstat -4l).
