If the machine is frozen ...
  1. Log in to another machine.
  2. Connect to the frozen machine using 'telnet ' (e.g. % telnet 2260u12). The machine name is indicated on the monitor.
  3. List the processes running on the frozen machine using 'ps' (e.g. % ps -x). The first column should list the PID's or process id's.
  4. Stop the processes using 'kill -9 <PID>' (e.g. % kill -9 345). You can kill the processes one at a time until you regain control of the frozen machine, or you can kill all the processes. You want to kill the application that caused the machine to freeze before any other process (e.g. Netscape)..
