CentOS-7 - Red Hat - Linux

Set-up the following.

1. A SSH server is running by default on each of your VMs.

2. Setup a firewall rule to allow access if one is not already there by default.

3. Secure both systems by applying the techniques illustrated in the Securing SSH document.

4. Implement public/private keys to be able to authenticate into the systems without a password.
