Is it possible to set ssh listen on two ports? I want to have the standard port listening as usual as this is used by rsync etc, but also to have a secondary port listening for other connections. This is because I have two servers sitting behind a portforwarding router and I want to set a second port to forward to the backup server so I can ssh both remotely. At the moment I ssh the main one... and then ssh the internal ip from that shell!!...which is a bit cumbersome.
