What is X11 forwarding?
ssh provides a protocol for sending X11 graphics between computers. This option needs to be turned on within your ssh program, such as SecureCRT or ssh, etc. If you use SecureCRT you need to enable X11 forwarding. Look for this option in your SecureCRT preference or global settings.
How do I connect to the cluster from the Blake Computational Studio in Anderson Hall?
Blake Lab is currently configured to use WinScp for transferring files between your Windows account and the cluster.
For ssh and X11 there is a linux virtual(program) running on lab PCs. Just login to one of the Blake systems and click on the linux icon on the desktop. It automatically boots into guest mode so you won't have to login to linux or anything. Once established a terminal window should start up automatically. From there you can login to the cluster with ssh:
ssh -Y -C UTLN@cluster.uit.tufts.edu
Make sure x11 over ssh works by typing xlogo at the cluster shell prompt.
This should bring up a small window with an X inside of it.
From this point you can start any of the cluster applications as one would normally do.
If you have any questions on getting to the cluster from Blake Lab, desktops @ Tufts or your own laptop, contact Shawn Doughty via email at: staff@asunix.tufts.edu
