Bad UID for job execution MSG=ruserok failed validating user1 from ServerNode while configuring Submission Node in Torque

Supposed you have the error when you are testing your submission node for torque. Firstly do take a look at the blog on Configuring Torque Submission Node

I'm using Torque 2.5.3 and MAUI 3.3.1

$ echo "sleep 30" | qsub -I
qsub: Bad UID for job execution MSG=ruserok failed validating ..... from server server1

The Error could be coming from 2 possible misconfigurations

Step 1: Do check that your Torque Server Configuration has the followings. You can check by doing

# qmgr -c "p s".
.....
.....
set server submit_hosts = submission_node
set server allow_node_submit = True 
.....
.....

If not you can add it in very quickly

# qmgr -c 'set server submit_hosts = submission_node'

# qmgr -c 'set server allow_node_submit = True'

Step 2: Start the PBS services in sequence.
From my observation, we do not need to start the pbs_sched just the pbs_server only

# service pbs_server start

Step 3: Finally make sure in the Primary Submission host, you configure to allow traffic from /etc/hosts.equiv

# vim /etc/hosts.equiv

# dns_name_of_secondary_hosts
