Hello,
I've used x2go on a very similar setup in the past but I'm running into a problem on a new installation. I've installed x2goserver on a CentOS 7.5 machine - simply a yum install via EPEL. I'm trying to connect from a Mac running 10.13. I can ssh password free between the machines with no issues. When I try to connect with x2go, I get this in my client window:
Error: Failed to resolve address of 'localhost'. Loop: PANIC! Unknown remote host 'localhost'. Error: Unknown remote host 'localhost'. Session: Session terminated at 'Tue Nov 27 08:06:01 2018'.
On the server side, I see this in /var/og/messages:
Nov 27 08:06:01 valkyrie /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID dvicker-51-1543331158_stDMATE_dp32
The server machine is in our local DNS and I've made sure the IP address is in /etc/hosts and matches the hostname. Any idea what is going on here? Is there a way to disable the host lookup?
