Generate Your Keys

Now that you have chosen your instance, but before starting you actually start your instance, you need to generate your key pairs. The keypairs are SSH keypairs. A later post will explain SSH in greater detail but the keys come in a pair because there is both public and private components.

SSH is a Secure SHell. This is a command prompt like a DOS box or a telnet connection. However, unlike DOS and Telnet, it is very secure. The private key is the local machine’s secret password. The public key is shared to any host that the local machine will connect to.

Linux Access with SSH & PuTTY

This post will (attempt) to explain what SSH and PuTTY are so that as a user you understand the terminology of AWS and so that you can be productive in the environment. This post will not attempt to make you an expert in SSH. For best practices in implementing SSH, I strongly recommend a book dedicated to hardening *nix (Linux, Unix, Solaris, etc).

SSH

In the early days, not that long ago really, of networking, very simple tools were used to work with remote computers: telnet as a console, ftp for file copying, rsh for remote command execution and others.
