test.
To log in to the Linux Machine , use telnet with your  Algo­
nquin  userid  (abcd0000) and the Web password you used when
you registered with the instructor this term.  (You can  not
do this test if you are not registered with the instructor.)
Do not put any valuable files on the Linux Machine   -  they
will be erased before and after every test.
The IP address of the Linux Machine  is 205.211.47.76
