The qstat command should either work or let you know the node isn't an admin/submit node. A simpler test might be to try the qping command to check basic connectivity to the qmaster. It might be a routing issue. Around here our login nodes are dual homed. Possibly the login nodes are trying to access the qmaster via the external interface for some reason. > > - Sangmin > -- William Hay <[email protected]>
