I did not change the port, so it should be listening on the default port 22. The client setting for the local SSH-port for file sharing is 22.
Okay, can you please provide me with the output of
sudo lsof -n -i | grep -i ssh
and
ls -ldh /etc/ssh_host_rsa_key.pub
Looks like you don't have an RSA host key (which would be weird, if the system sshd is actually running.)
In that case, X2Go Client currently spawns a private sshd instance *with an DSA key*. Newer OpenSSH versions deprecated DSA keys, though, so that's probably the reason why starting it up fails.
