I have a Linux machine on my network. I connect to it using SSH with PuTTY over the Internet, so I have forwarded port 22 to the machine.

Now I need to put another Linux machine on the network. I will want to connect to this new machine using PuTTY as well. I want to run telnet/SSH on it using a port other than 22 so that I can forward it.

How can I make this happen?

It's not completely clear what you are asking. Are you configuring your ssh server or your telnet server? – Olli Mar 21 '11 at 18:14

@DanielBeck: this was flagged as belonging on SF, and there is already a question like it (see peelman's comment above), so instead of migrating and having it closed there, I just closed it here... – studiohack♦ Mar 21 '11 at 21:00
@studiohack I was confused about going to SuperUser or ServerFault. – TheVillageIdiot Mar 22 '11 at 3:45

It depends on your ssh server (and Linux distro).

Check out /etc/ssh/sshd_config (or similar, this is at least in Debian based distributions).

There is line

Port 22

Change it and restart your sshd (usually /etc/init.d/ssh restart, it may be also /etc/init.d/sshd).

You are running from outside of the network? (internet connection?) If not you don't need to forward port and just connect with ssh ip or ssh hostname (or equivalent using putty configurations). If you are out of the network and need port forwarding, you only need to edit /etc/ssh/sshd_config server file and change the #Port 22 line to the port you want and remove comment. After you need to restart ssh on the server.
