1) Login on another machine using the same login and password
2) At the Unix prompt, type in ssh <name_of_frozen_machine> The names are on the machines and also at the prompt. You will get the familiar login screen after which a Unix prompt will appear.
3) At the new Unix prompt, type in psg arc if you
were running an arc program at the time the machine froze (you can
also type psg imagine, psg netscape, etc.) You should get a list
of all arc,
imagine, netscape, or etc. processes that are currently running and
their PID #s.

4) Type zap and the correct PID number Note: don't
type PID, type the number shown under PID!
You will get a message that says `PID killed with SIGTERM'
after which the machine should free up!
5) If the machine is still frozen, try zapping another process.
If the machine is still frozen, try the psg command with another program.
If you tried psg arc, for example, try psg netscape. If you still
can't get it, tell Bonnie, or your instructor.

PLEASE
DON'T JUST WALK AWAY FROM A LOCKED MACHINE!!
6) After freeing your machine, make sure to type in exit in
order to break the rlogin connection, and then log out.
7) If your machine is not frozen, but the program you are
using is, just get another UNIX window and type psg imagine, psg
arc, etc. at the UNIX prompt. Then just type zap PID#
as stated in the steps
above.
