Testing the Worker Node

You can test if the required services are running on the worker node by using the netstat command.

#netstat -tnlp
       tcp    0    0    0.0.0.0:15002    0.0.0.0:*    LISTEN    /pbs_mom 
       tcp    0    0    0.0.0.0:15003    0.0.0.0:*    LISTEN    /pbs_mom 
       tcp    0    0    :::22            :::*         LISTEN    /sshd

Testing the batch system software on the worker node can be done via the momctl command. -d speficies the debug level of the output
