    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.

    SSH can listen on multiple ports. Just add additional ports in sshd_config like this:

    Port 22
    Port 8888

    restart sshd daemon and you are good to go.

    hi, this is great, but what then shall be my command in terminal?
    is enough?
    I need to access the server listening to 2 ports.
    I use
    ssh -L 80:localhost:80 [email protected]
    ssh -L 13013:localhost:13013 [email protected]
    on a separate terminal

    To access a server on a different ssl-port, use ssl -p PORT ....

    will sshd: in /etc/hosts.allow work for both ports or can I setup different rules for the second port?
