So, on my firewalled work-PC I have one port open that I connect through using cygwin and OpenSSH, anyway I use the SSH connection to tunnel communications between my computer and the remote controll software running on my workstation(Remote Administrator).

Problem is I reinstalled my OS and now I forgot which port I should redirect the tunelling to on the remote computer, is there any commands of methods I can use to find out which ports are being listened to?
I am able to log into the openssh server and I have console access, but thats all.

In windows XP, 2k start a DOS Session and "netstat -an"

Thanks, just what I was looking for, got it working now.
