[PLUG] What's the best utility to find source of outbound net traffic?

["Greg Helledy" <gregsonh@gra-inc.com>]

I re-installed Kubuntu on Friday evening, and on Saturday uncommented some
sources in the apt.sources file to install some software from the
"universe" and "multiverse" collections.

Now my dial-on-demand link stays up all the time.  My firewall machine
reports incoming traffic from the Kubuntu machine on port 31000, which
requires a DNS lookup:
May 21 05:59:49 firewall diald[1524]: Trigger: udp       192.168.1.5/33100
  207.69.188.185/53

I had this problem once before with some Windows software always "calling
home" and figured it out by installing an old copy of ZoneAlarm.  What
should I use on linux to figure out what app is going out to the net while
the machine's idle?
