What rights do I have on the VCL machine?

On custom Windows and Linux environments you have adminstrative and root level rights. Since the VCL system reloads each expired reservations with a clean environment, there is no threat of any residual data being left on a machine for the next user.

On Linux and Solaris Lab machine environments, you only have user level rights. The same premissions as you would experience at the console of a walk-in lab.
