Passwordless Connections to Unix

The Secure Shell (SSH) protocol uses encryption to provide authentication and privacy when logging in to other computers over a network, such as Romulus, Remus, or the Computing Cluster. It can also be used to securely execute remote commands. By default logins use a password, but it's also possible to set up passwordless connections. The latter are very convenient, and are also required to initiate remote commands. However, for security reasons they should not be used from computers that are accessible to others.

Windows SSH: PuTTY

PuTTY is an open-source SSH client for Windows that lets you initiate interactive command-line sessions with Romulus and Remus, the twin Amherst Unix servers. How to Get PuTTYPuTTY is free software. If you are on the Amherst network you can copy it from Winsoft to your Windows computer. Note that PuTTY doesn't "install" as do most Windows applications. Rather, it is a self-contained executable named putty.exe. All you need to is copy it to your Windows desktop and double-click to run it.
