[Mun] With 'qrsh -w p' and 'qrsh -w v' I got the following output:
verification: found suitable queue(s)
I then replaced the -w option with -verbose which produced the following output:
waiting for interactive job to be scheduled ...timeout (54 s) expired while waiting on socket fd 4
Your "qrsh" request could not be scheduled, try again later.
I have no idea what is meant by "socket fd 4"; but that leads me to believe we have some sort of blocked port or something.
Are there any additional ports that need to be opened up in order to use 'qrsh & ssh -X' ?
One last noteworthy item that recently occurred to me is that when SGE was initially installed on our servers, we had a different domain name. Late last year we were acquired and our domain changed. However, our /etc/hosts still has the old domain simply because SGE couldn't deal with the change in the domain--or rather, it was the easiest course of action for me to take and keep SGE working. I wonder if that is in some way interfering with 'qrsh & ssh -X'?
I am going to try and do some additional debug today and will report any progress.
Thank you and regards,
