[torqueusers] Torque 2.5 error - key verification failed

[John Keller]

Hi all,
I have Torque 2.5.11 installed on a server and compute node, both
running SUSE 12.1. "qmgr -c 'p s'  " and "pbsnodes -a " give normal
output. pbs_sched is running. However when I do "qsub test.sh" where
the script file contains a simple command, the output ends up in the
/undelivered directory on the compute node, and "qstat -f" shows
"unable to copy file....key verification failed.."

Does torque require passwordless SSH or RSH to be working properly?
