Documentation:SSH Howto
From UGCS
SSH
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 <username>@to.ugcs.caltech.edu
Mac
Open a terminal (you should have one in your Applications folder), and run the following command:
ssh <username>@to.ugcs.caltech.edu
Windows
Download putty from http://www.chiark.greenend.org.uk/~sgtatham/putty/ and run it. You should use to.ugcs.caltech.edu as the Server Name.
