We are running a SGE / OGS compute cluster on EL6 and are trying to launch an interactive Ansys Workbench. This works using SSH with X Forwarding, but using qrsh fails to run the Mechanical component - Workbench itself does launch OK.

It looks like it cannot launch / connect to a high port it is trying to access on localhost. We think this may be an issue with the grid software? How can I allow high ports on loopback to be used? We're authenticating using kerberos across the entire computing infrastructure so it's using tickets to log in to interactive jobs.

I follow below steps to configure workbench and other interactive jobs using qrsh.

  1. create file qlogin.sh

    #!/bin/sh
HOST=$1
PORT=$2

if [ "x$DISPLAY" = "x" ]; then
exec /usr/bin/ssh -p $PORT $HOST
else
exec /usr/bin/ssh -X -Y -p $PORT $HOST 
fi

  2. Now modify the configuration using qconf -mconf

    qlogin_command               /opt/gridengine/bin/qlogin.sh
qlogin_daemon                /usr/sbin/sshd -i -o Protocol=2
rlogin_command               /usr/bin/ssh
rlogin_daemon                /usr/sbin/sshd -i -o Protocol=2
rsh_command                  /usr/bin/ssh
rsh_daemon                   /usr/sbin/sshd -i -o Protocol=2
