That's not what he asked for.  He wants a listening client, like
vncclient in "-listen" mode, and wants the server to initiate the
connection, without any manual interaction on the client side.  The only
way to approximate that behavior is starting x2goclient over the
server-initiated ssh connection, and passing the required parameters for
an autostarted session - see my more detailed reply to him.
