[torqueusers] compute nodes appear down

[vitor at ceset.unicamp.br]

Hi,

I have a cluster with 5 machines (1 headnode and 4 compute nodes). I
installed torque-2.3.0 in the headnode. Using make packages I installed
pbs_mom in the compute nodes.
When I tried to look for the nodes I got (pbsnodes -a)

     state = free
     np = 4
     ntype = cluster
     status = opsys=linux,uname=Linux holmes 2.6.25.6-55.fc9.x86_64 #1 SMP

a2
     state = down
     np = 4
     ntype = cluster

a3
     state = down
     np = 4
     ntype = cluster

a4
     state = down
     np = 4
     ntype = cluster
-----------
Using /usr/local/sbin/pbs_mom -D on the headnode I got no problem but in
the compute nodes I got
MOM is up
do_rpp: cannot get protocol Premature end of message

Any suggestions of what is causing that?

Thanks,
Vitor
