Which services are listening on my open

By pete_may ·
I work on a small (50ish users) NT4 network and I am trying to gain some understanding of security issues. I recently got hold of a copy of SuperScan to help moniter the network. It can tell me which ports are open on which machine but how do I findout which service or program is listening on this port. And how do I close the port if it is unneccessary.
I use netstat but only to see if a machine such as the mail server has an excessive number open connections.

Which services are listening on my open

I would look over RFC 1060.
http://www.cis.ohio-state.edu/rfc/rfc1060.txt
Its got all the port and what they do.
exa: 137=NS NETBIOS Name Service.
To close off ports, try the firewall
programs out there. Nortons internet security
and the like.

Thanks for the rfc refernce but SuperScanner already tells me the program officially accotiated with a port but some programs assign dynamically and our web server is listening on 1027 officially ICQ but no ICQ. I want to find offending program and shut port there
Thanks anyway
Peter :-)
