see /etc/services
DEBIAN NEWBIE TIP #19 from Dave Sherohman <[EMAIL PROTECTED]>
:
How do you determine WHICH NETWORK SERVICES ARE OPEN (active)?
Try "netstat -a | grep LISTEN". To see numeric values (instead
of the common names for services using a particular port) then
try "netstat -na" instead. For more info, look at "man netstat".
Also try "lsof -i" as root. "man lsof" for details.

DEBIAN NEWBIE TIP #38 from Alvin Oga <[EMAIL PROTECTED]>
:
Curious about your NETWORK TRAFFIC? There's a whole bunch of
ways to monitor it: iptraf, showtraf, netwatch, tcpview, statnet,
or even
tcpdump | grep 'what you want to see'
lsof -i | grep 'LISTEN'
For network statistics try "mrtg". See the ethernet section
over at http://www.Linux-Sec.net/
