Show who's using each IP port? 2

[cpjust]

Is there a command to show what programs are listening on which ports?
'netstat -a' shows me all the ports, but I have no idea what programs they're connected to.

Also, [tt]netstat[/tt] has a [tt]-p[/tt] option:

   -p, --program
       Show the PID and name of the program to which each socket belongs.

This probably won't help in a Linux environment, but in Windows I use netstat -aon, open task manager, use view > select columns to add process ID (PID), and then match the PID for the port I'm interested in to the PID in task manager.

Thanks, netstat -p works great for Linux, but unfortunately it doesn't work on Solaris. :-(

Is there a corresponding command on Solaris?

You'll have to use lsof in Solaris:

lsof -i tcp:22

as an example...

The [tt]fuser[/tt] command can be used for the same thing with slightly different syntax:

fuser 22/tcp

Try the [tt]-v[/tt] option, too.

This is a nice resource for when you know how to do something on one Unix variant and want to find an equivalent for another:
