Try The New Virtual Machines!

You should now be able to connect to Linux through the virtual machines - just type

ssh -XY netid@login-teer.oit.duke.edu

and that will take you to a Teer-like machine (for those who remember there being Linux machines in Teer) that should have no problems. This page will likely go away quite soon since the login-teer system is working.
