UGCS provides shell access several different classes of machines. To log into the machine with the lowest current load, use to.ugcs.caltech.edu.

If you want to use the mortals, log in to mortals.ugcs.caltech.edu

UGCS does not support SSH keys. Instead, use Kerberos with SSH

If you need an SSH client, we recommend OpenSSH for Linux, Unix, and Macs, and Putty for Windows.

Linux
Open a terminal (on Gnome, it is in Accessories), and run the following command: ssh @to.ugcs.caltech.edu

Mac
Open a terminal (you should have one in your Applications folder), and run the following command: ssh @to.ugcs.caltech.edu

Windows
Download putty from http://www.chiark.greenend.org.uk/~sgtatham/putty/ and run it. You should use  as the Server Name.
