[X2Go-User] Successfully developed X2Go Client and Plugin for Open Thin Client BUT receiving and error when connecting.

[Mahmoud Ramadan Ali]

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 at 192.168.1.6" command.

root at dhcppc3:/home/tcos/.ssh# ssh -v root at 192.168.1.6
