application and port

By phillip_pbn ·
is there a way to find out what application is listening for a certain port ?
For example, when you run netstat -an
it reports these:
TCP 0.0.0.0:171 0.0.0.0:0 LISTENING
UDP 0.0.0.0:1026 *.*
How can I find out what application is listening tothese port ?

According to RFC 1700
http://www.faqs.org/rfcs/rfc1700.html

These are the ports you specified:

multiplex 171/tcp Network Innovations Multiplex
multiplex 171/udp Network Innovations Multiplex

port 1026 is undefined and can be used by anything.

You can also run just the Netstat command by itself to view just the active connections.

Knowing what ports are being used by each app is sometimes by process of elimanation, if it is not a well known app. I would first take everything out of your startup menu, reboot then run the netstat command and see what is listening by default.

Then with the command still running bring up 1 app at a time and see what happens.
