Hi Dears, I've successfully developed X2Go Client and Plugin for Open Thin Client BUT receiving and error when connecting saying "access denied. authentication that can continue publickey password". I think that the client can NOT verify the public SSH key of X2Go Server but i tried to SSH to the server and get connected without any issues,then i verified that there is NO public key mismatch using the "ssh -v root@192.168.1.6" command.
