I've installed x2go on both my client pc (Kanotix/Debian Stable) and my server (salineOS / Debian stable) I configured my router with a dyn-dns adress and a port forwarding to my server but cannot login with remote from my client PC. When I try x2go freezes or I get this message:
*Host key for server changed.*
*It is now: 4c:53:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx*
*For security reasons, connection will be stopped* It has worked before but now it doesn't anymore. I reinstalled the Linux on my server maybe this is the reason? Could anybody here help me with that problem?
Re-installing your server is the same as redoing the servers ssh-key. And as a changing ssh-key of the server could mean that your connection is intercepted by a man-in-the-middle, ssh stops working at that step and shows you some hints what you might do to correct it. Please use ssh from a terminal (konsole, xterm, whatever) and watch the output when connecting to your server. Then follow whats written there.
What does ssh have to do with your x2go-problem? ssh is what is happening on the transport-layer below the nx/x2go-protocols to create a secure and trusted connection.
Have fun,
