How to find which service is using which port?

[Guest]

Hi

Is there a way to find out which service is using which UDP port?

I am trying to install an application but the installation process keeps indicating the
UDP port is used by some other service and needs to disable it

I know the UDP port but cannot identify which service

Thanks
Sophia

Would have helped if you had mentioned the application / service...

Whats wrong with netstat?

netstat -a for all connections
netstat -e for ethernet stats
netstat -r for routing table + connections

netstat -a > makeafileondisk.txt

Try tcpview from www.sysinternals.com

theres a tool from foundstone called fport.
you run it from CMD, and it gives u the netstat output and
the services that are mapped to it. with this ushould get
all you should need. alos ther are a number of freeware
gui apps that do the same thing.

How about the obvious? netstat doesn't tell you which application is
using which port!

It does, with the -p option, eg:

server:~# netstat -ulnp | grep 111
udp 0 0 0.0.0.0:111 0.0.0.0:* 643/portmap

-u: udp
-l: listening
-n: numeric
-p: process

see netstat -h
