mpiexec and Fedora 6 problem

[Tony Schreiner]

Hi

Just joined this list.

I am having trouble with mpiexec v 0.82 on a Fedora 6 system, with  
torque 2.1.6-1 from the Fedora repository.

The same build is working fine for me with Fedora 4.

 From my master, I run

qsub -I -l nodes=node5:ppn=4

where node5 is my node recently clean installed with Fedora 6

ldd /path/to/mpiexec
         libtorque.so.0 => /usr/lib64/libtorque.so.0  
(0x00000039c8a00000)
         libc.so.6 => /lib64/libc.so.6 (0x00000039c9600000)
         /lib64/ld-linux-x86-64.so.2 (0x00000039c8600000)

when I try to run my application, which is a simple test of MPI

/path/to/mpiexec ./mp
mpiexec: Error: get_hosts: pbs_connect: Unauthorized Request .

can someone shed light on this error for me?

THe PBS_NODEFILE contains
node5
node5
node5
node5

and node5 is in /etc/hosts

Thanks in advance
