[torqueusers] No contact with server at hostaddr problem

I have managed to mis-configure pbs to give me these symptoms in two ways:
1) pbs_server isn't running on the port that the mom thinks it is. Make
sure that the pbs_server is running on 15001 (looks like you're already
looking at this). As mentioned not long ago, you can start the mom with
pbs_mom -S 15000 to force mom to look for the server at port 15000.
(though I suppose a wise thing to do may be to see what port pbs_server is
running on first).
2) Fudged up ethernet names for the server on the mom (personally, I've
done this with multi-homed servers). Does the mom-node (cree?) know who
huron(server) is (and vice versa)? Is that an entry in /etc/hosts on the
mom-node? Being a wimp, I almost always use the ip of the server in the
config file for the pbsserver entry to avoid making this mistake.
I suppose the third option is that pbs_server is actually running at all
Hope that helps,

RE: [torqueusers] No contact with server at hostaddr problem (followup)
Sorry I wasn't clear
My set up is
Node1 (cree): running pbs_server, pbs_mom and maui
Node2 (huron): running pbs_mom only
When I submit the following on cree
echo "sleep 30" | qsub
the job appears to be scheduled on huron and runs OK but then I start
seeing the "No contact with server at hostaddr port 15001" error
messages repeated in the mom_logs file on huron and it appears that the
pbs_server never is notified that the job ran to completion.
Hope this clears things up a little.

It is a little hard to figure out your setup here with "client",
"server", and "remote" nodes.
If both hosts are to handle compute jobs, then you want pbs_mom running
on both hosts and both hostnames in server_priv/nodes.
