Exercise 1 - Secure Communication Using SSH

In the old days, telnet was used to establish remote connectivity with another server. The key problem was that telnet did not secure the communication over an unsecured channel, such as the Internet. SSH secures the communication even if it is taking place over the Internet.

In this exercise, you will learn to secure communication using SSH.
