    Dear All,

    I am trying to setup batch scheduling software (openPBS) on my new linux
    cluster and am encountering a few problems with communication
    I can get everyting running on the server and compute nodes. I try and
    submit a job to the server
    qsub testfile

    where testfile contains:
    #!/bin/sh
    #PBS -o jobname.out -j oe -N jobname
    #PBS -l cput=500:00:00,ncpus=2
    #PBS -l mem=128mw,nodes=1
    echo Working directory is $PBS_O_WORKDIR
    echo tmp directory is $TMPDIR
    echo env is $ENVIRONMENT
    echo Running on host `hostname`
    echo Time is `date`
    echo Directory is `pwd`
    echo This job runs on the following processors:
    echo `cat $PBS_NODEFILE`
    echo pbs job id is $PBS_JOBID

    test.sh > output

    and the file test.sh conatins the line
    echo hello world

    the job submits but the copying back of the script output gives the me
    errors

    I think it is to do with the way that my network is setup and I need to
    setup some hosts files but I am not sure which

    On my server the computenodes are in the hosts.equiv file and on the
    computenodes the server is in the hosts.equiv file

    Does anyone have any ideas as to what might cause these problems
    i can provide more details if necessary
    Cheers for now Martyn
