process id

hi folks,
how do you find a process id if you are given a port number?

there are couple of ways:

1. if the process is a "well known" and/or sits on the stadard ports under just see the file /etc/services
2. if you have to find a port for an ongoing connection that may be using the "ephemeral" port see netstat -p

You can also try lsof:

Code:

lsof -i tcp:port

or udp if your app uses that. Note that you'll have to be the owner of that process in order to see it listed.

Salut
