Dear John and others, first of all, I am reading the list now for some years and I gained quite a bit of knowledge here, so why shall I leave? Don't worry, I got no intention to do so.
I can see you point and I have already contacted the cluster support. However, I have mixed experiences with support in the past. The last cluster I was working with was basically the hardware and the guys from out IT installed the OS on it. They probably had a hell of a time to do so, but the consequent clusters are easier to install (for them). As they don't know computational chemistry and I want to use the programs, we made the inofficial deal that I am dealing with the programs and they with the OS. So we both learned something and the system was running. Things are different here and I slowly have to find my way around. To be honest, I stumbled over some severe missconfiguration, hence my trust in that company is not strong. Being upfront as I am, there is some substantial sloppy workmanship in the software installation and it already took me some days to iron out some of it. Even though the cluster grew over the last years, one certainly can do better. For that reason I was asking here for some new ideas how to tackle the problem and, to be honest, I am impressed by the feedback I got from here. I am on the GAMESS list as well and this error comes up there some times. Usually it is a misconfigured hosts file, sometimes firewalls as people are using machines connected to the WAN instead of a local, private LAN. I can rule that out. I thought I reply in more detail to John's post to show that I am not offended and what motivations I had to post here. All the best from Glasgow!
