EITHER:
  For connection to Gamma Lab computer,
  open a command line window and enter:

  ssh -N -L 5800:192.168.163.111:5901  student@alab.physics.drexel.edu


OR:
  For connection to NMR Lab computer,
  open a command line window and enter:

  ssh -N -L 5800:192.168.163.112:5901  student@alab.physics.drexel.edu

IF the above complains about not finding your ssh private key,
add "-i <pkfile>"  to the command, where substitute <pkfile> for your
ssh private key file.  Normally, that would be located somewhere
like your_home_directory/.ssh/id_rsa, which should be found automatically,
but otherwise you'll need to use the "-i " option.

THEN:
if the ssh doesn't throw an error; looks like it's just sitting there.

***do not close the window with ssh***

open the vncviewer, type in address: localhost:5800

and you should be looking at a Windows desktop.
