There are two methods for changing your password. The easiest is probably on the web:
https://www.cs.rutgers.edu/common/admin/password/
There you can change your password if you know any of your CS, RCI or
Eden passwords.
You can also change your password from the shell using the passwd command. For historical reasons, you have to do this on the YP master of the cluster you are on. The command "ypwhich -m passwd" will tell you which machine that is.
aramis% passwd

In the above example, the cryptic error message means you typed your
old password incorrectly.
