That was exactly it.... Thanks a lot. It was weird, since I would say that I had it working before, and I don't remember any change going on the infrastructure.
But thanks a lot. On 13/11/18 16:14, Stefan Baur wrote:

Is there any restriction for it? I am connecting to the x2go server using password or ssh key, and trying to ssh to the node using ssh key or password, it doesn't matter. Thanks.Using a key file isn't trivial in this situation. I would suggest making your first attempts using a regular username/password combinations. First, try pinging the destination server from within the X2Go session. If you can't ping it, the problem might not be with SSH but with an underlying network (mis)configuration). Running traceroute and looking at/posting the output can't hurt, either. Also, crank up the verbosity level of the ssh client inside the X2Go session like so: ssh -vvv user@host You might also want to try to ping with larger packet sizes, like so: ping -s 1500 host if a regular ping works, but it fails when specifying "-s 1500", it might be an MTU issue. Start decreasing the number until you can get a successful ping through, then set the MTU on the interface to that value. -Stefan
