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.
