Enable SSH (Secure Shell) in Ubuntu 12.04 (Precise Pangolin)

This brief tutorial shows you how to enable SSH in Ubuntu 12.04 Precise Pangolin. This request came in from one of our readers who wanted to know how to enable SSH in Ubuntu 12.04. As you may already know, SSH is a secure communication protocol that lets you remotely access networked computers. It is known as a replacement for Telnet which is very unsecure. While Telnet sends traffic in plain text, SSH on the other hand uses a secure protocol to communicate.
