    Try "ssh -X server_name -l login_name". Per the man page for ssh, the -X flag:

    Enables X11 forwarding. This can also be specified on a per-host
    basis in a configuration file.

                  X11 forwarding should be enabled with caution. Users with the
                  ability to bypass file permissions on the remote host (for the
                  user's X authorization database) can access the local X11 display
                  through the forwarded connection. An attacker may then be able
                  to perform activities such as keystroke monitoring.
