Ssh (Secure Shell) is a program used for logging onto a remote machine or for executing commands on a remote machine. It provides secure encrypted communications between two hosts over an unsecured network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel.
New for Spring 2021
Keypairs are back! As of June 2021 we no longer use password authentication, except for first-time users and users who have recently changed their passwords. You will need to upload public keys for each device you wish to use to connect to the CS department. You can upload keys from your CS website profile page.
