Hi,<br><br>it seems that the problem arises either from the firewall configuration or the hostname resolution of your server.<br>Make sure that you have the following ports open in your firewall because from my experience oscar does not
<br>does not change them:<br><br>pbs 15001/tcp<br>pbs_server 15001/udp<br>pbs_mom 15002/tcp<br>pbs_resmom 15003/tcp<br>pbs_resmom 15003/udp<br>pbs_sched 15004/tcp # not used by oscar
<br><br>if that does not fix your problem make sure that you can access all the nodes and the oscar nodes with their<br>hostnames and without ssh asking for password. The easiest way is to run the TEST CLUSTER (step 8) from
<br>the installation suite and make sure that SSH ping test, SSH server -> node , SSH node -> server are passed.<br><br>If not, you probably have to change the /etc/hosts on the server and/or on the nodes.<br><br>Finally maui does not use port 15004, it is used from the pbs scheduler which is inactive in oscar
5.0<br><br>I hope this helps.<br><br>Regards,<br>George<br><br>
