The server names are {carl,burns,smithers,lenny,snowball}.cs.indiana.edu. You
connect to them using the secure shell protocol, or SSH. On Mac OS X and
most Linux distributions, OpenSSH, the leading
open-source implementation of the SSH protocol, is installed by default. On
Windows this is not the case, and there are a bunch free implementations that you can download and
install.

Once you have ssh installed and working, you might want to:

1. Set up public key authentication for
   password-less login,
2. Learn how to use ssh-agent,
3. Manage host name aliases,
