Can you show me the exact command you are using to open the port using the ssh command? First you need to open the port on your PC (not on the headnode) through Mobaxterm. For instance ssh -L 4002:s005-n006:22 colfax-intel

opens the port on node graphics port for s005-n006. Please show the exact command you are running on the PC from Mobxaterm. Also note you first need to be logged into the compute node before executing this command. Cheers Larry

Hi Larry,

Apologies for the delay in my response. I was able to open graphics port and launch quartus on n137.

What I missed earlier was logging in the the node before opening the port.

In short this is what I did:

ssh devcloud

devcloud_login (select 137)

ssh -L4002:s001-n137:22 devcloud

Only at this point launch the X2GO session

from the command prompt of GUI,

tools_setup (select appropriate version)

launch quartus using

quartus &

Thanks a lot for your help.

-Sincerely,

Atharva
