To change your password on the CUIP Unix (Linux) server, you'll need to
log in using your username and current password, and connecting
to the plain command-line interface. You don't need to
know a variety of Unix commands to do that, as the example below
will model the process for you. Added explanatory comments
will be in parentheses and italic font. Apart from such
comments, the transcript below is simply what was on my screen when I
connected to change my password, and is close to what you will
see when you do the same thing. (Of course, use your own
username, old password, and desired new password.)
Making the connection is done with a program called "telnet".
- From another Unix computer, issue the command "telnet cuip.uchicago.edu".
- On a Windows 9x or NT4 computer, from the Start button select Run,
and in the line in the window that gives you, type "telnet
cuip.uchicago.edu". (There is a built-in program called "telnet", that
these instructions assume. But there are other programs for
the same purpose, and if you know one has been added onto your
computer you should use whichever one you prefer.)
- On a Macintosh, telnet is not built-in with the OS. There are a
number of programs of this type available. Most keep "telnet"
somewhere in their names, so if you do a file search on your Mac's
hard drive or an Apple server you're connected to, using "telnet" as
your search term, you may find a suitable program available for
use. If not, and you want to download and install one, try
looking for "NCSA Telnet" and "Better Telnet". (Though I'm not sure
if the latter is free.) The details of using these programs
obviously will differ; but the main thing is that the host
or remote computer you'll be connecting to is
"cuip.uchicago.edu", and there's got to be someplace to enter that info.
Things that I typed are in blue. Things the computer printed to the
screen are in black. Added comments are in parentheses, an italic
font, and maroon color.

New user password:
Retype new user password:
passwd: all authentication tokens updated successfully
(Okay, it worked! It might instead tell you the two
times you entered the new password they did not match, so you would
start again; or it might reject your choice of new password and explain
how to make it more suitable -- again, not too hard to
recover from, just try again.)
mmarks@cuip:~> exit (I've got no other tasks to deal with right now, so I type the exit command to end the session.)
