Connect from Behind a Strict Firewall

When attempting to connect to a remote visualization session from a location that is behind a strict firewall, you may encounter issues. In such cases, creating an ssh tunnel through a machine on the UIUC network has been found to provide a suitable workaround.

For example, to create an ssh tunnel to the remote visualization server vegas.ks.uiuc.edu through TCBG's external gateway login.ks.uiuc.edu, enter the following command on your local machine as a single, continuous line, substituting your TCBG username:

$ ssh `seq 7300 7399 | awk '{print " -L " $1":vegas.ks.uiuc.edu:"$1}'` -L 5901:vegas.ks.uiuc.edu:5901 cartman@login.ks.uiuc.edu

Instead of connecting directly to the server hosting your remote visualization session, connect to localhost:1 to access the server through the ssh tunnel.
