Hi all,

I ambuilduing up a new cluster running debian lenny, and i decided to
switch to torque.
Until now I just manged to do a first install of torque (version 2.4.8
from lenny-backports repo) and Maui (3.3.1 from source) on the server
(called hulk), and torque-mom on one execution node (called nodo-32).
I followed the guide on debianclusters.org to do so.
Everything seemed to be working, services are running, etc., but when
i try to submit a test job (echo "sleep 30") with a user, the job is
queued and deferred by maui. Here are what i consider relevant


tfischer at hulk:~$ echo "sleep 30" | qsub


tfischer at hulk:~$ qstat
Job id                    Name             User            Time Use S Queue

pbs_mom;Req;req_reject;Reject reply code=15008(Access from host not
allowed, or unknown host MSG=request not authorized), aux=0,
type=QueueJob, from PBS_Server at hulk


seems like the node is rejecting jobs from the server. The server name
is defined at the host like

nodo-32:~# cat /var/spool/torque/server_name

Is there something i am forgetting about or missconfiguring?

Thanks in advance,

Thomas Fischer
