Logging in to Linux

Local Login
Users with a physics department account can recognize Linux computers that are part of the department's single sign-on system by the spartan-yet-friendly login widget they display:

Just type your username and password in the obvious fields and you should get an X Windows session.

Remote login
Remote login via ssh is supported from anywhere in the world. The remote login server name is (unsurprisingly) login.physics.harvard.edu, so to reach it from a remote location use

ssh username@login.physics.harvard.edu

where, of course, you should substitute your real username for username in the above command.
