To All Just letting know that I have solved this problem. After being given some hints I dumped the network traffic between the two servers and found the requests were coming from the incorrect server name. The submission/login node has two interfaces with two different names, public & private, with the private one being used for all HPC/torque traffic. This private interface is the one that is advertised in /etc/hosts however I had run oscar_wizard to check on some configuration and this had modified /etc/hosts and removed the private address name and added the public address name, therefore torque was seeing the wrong name/ipaddress combination and rejecting requests.
I have manually corrected /etc/hosts on all servers and everything now works correctly. Thanks again --------------------------------------------------------------------- Richard A.

I have recently come across a problem with one of my submission nodes on our HPC and was wondering if somebody could help. Our HPC has two submission/login nodes and one head node, both submission/login nodes were setup the same and working until recently. One of the submission nodes now gets the following error whenever a torque commands is run: qstat: Invalid credential MSG=Hosts do not match qmgr obj= svr=default: Invalid credential MSG=Hosts do not match torque was install via rpm is version of 4.2.9. Both submission/login nodes are setup in the queue configuration correctly, as below, they were taken out and put back with the torque server and client restarted. The file /var/lib/torque/serv_priv/nodes has both servers in it, and this hasn't changed. set server submit_hosts += server1 set server submit_hosts += server2 The problems exist for all users and the admin account. Has somebody seen this problem before and can provide some help in fixing it. Thanks --------------------------------------------------------------------- Richard A.
