PuTTY is a freely available SSH client for Windows. SSH (Secure SHell) is a secure replacement for Telnet. Where Telnet transmits everything in plaintext, SSH encrypts all transmissions.

1. Install PuTTY using the PuTTY Installer
2. To use the CASLab's pre-configured settings for PuTTY, download putty_caslab.zip and extract the Windows Registry file putty_caslab.reg from it and then double-click on that file to install the settings.
3. You can now log in to CASLab Unix/Linux as you do from the CASLab Windows machines.
