[X2Go-User] ssh connection through bastion host

[Ulrich Sibiller]

Hi,

the x2go is using libssh, which _partly_ reads your openssh config
files. It understands _some_ of the options, but not all.

You can use your ProxyJump setup in conjunction with -L to establish a
port forwarding outside x2go and then use
localhost:<your_forwarded_port> in the x2go connection dialog.

Also, x2goclient knows some debug switches to produce log files. You
might see what's going on.

Third, if your bastion host is running some kind of restricted shell
you can try to use !<hostname> instead of <hostname> (preceding the
hostname with an exclamation mark) in the connection dialog (for
destination or proxy or both) to disable some checks that might
trigger your restricted shell to fail.

HTH,
Uli
