PuTTy: Install and Configure Remote Access for Windows (SSH)

For security reasons Secure Shell (SSH) has replaced Telnetas the supported method of remote access. SSH provides a secure connection between the user’s computer and the remote computer or server.

Why would I access a remote machine with SSH?
SSH is used to connect your computer to another computer or server securely. It is most often used with Unix servers so that you can work from your own computer as if you were sitting right at the remote computer. The session runs on your computer, but the information is processed on the remote computer.

How do I access a remote machine with SSH?
On a Windows machine using PuTTY software, on a Macintosh computer using Terminal software.
