If you're using Mac OS 7.x/8.x/9.x, you can log into your IT Linux
account by using a program called MacSSH. This program can also be
used on Mac OS X, however you will be required to have Classic
installed on it.

Note: You may find that SSH2 is not working with a "no supported
authentication methods" error when trying to connect to OpenSSH
servers. A work-around was added to the user comments below:
> MacSSH generates PUTTY-style keys with linebreaks, and you need to
> edit those breaks out in a text editor for OpenSSH to accept the
> key.
With thanks to jons_old_g3 for the heads-up.
