Hum... if there are no stale X sockets, why is x2gostartagent counting up?

What do ps axu | grep -iE '(nx|x2go)agent' and x2golistsessions_root say?

Okay, that's interesting and maybe explains why authentication is not working
properly. You seem to be affected by the same issue that the tcsh user saw
earlier - HOSTNAME is set to a FQDN name, while the authentication requires a
short name only. Something seems to be setting and exporting HOSTNAME to a value
other than the autogenerated value that bash employs.

Can you please upgrade your system? You're already using nightly x2goserver
builds, so just updating should pull in a fix for this issue. Your version is
just one day shy of the date I published a fix for it...
