Hi Tom,

> There is a valid hostname configured. This is what is puzzling me.

Check if "uname -a" in SSH reports the same hostname as the GUI has
configured in "System Settings" / "TCP/IP".

You could also change the hostname in "System Settings" / "TCP/IP" back
and forth once and that should solve it.
