So far, you have learned to use the ssh utility to establish a secure connection to a remote server to perform tasks, administer the server, etc. For these common operations, you have issued the ssh command, which is the client application for ssh. In order to connect to a remote server (like your VMs, Matrix, etc) they need to be running the SSH service. In this lab, you will learn how to run an SSH server in a VM, then confirm that you can connect into the server by using the ssh client application.
We can use the netstat utility as a trouble-shooting / confirmation tool to view the SSH service and determine which STATE the SSH service is performing:
*'''LISTENING''' (waiting for a ssh connection attempt)
*'''ESTABLISHED''' (connection established)
*'''CLOSED''' (connection is closed)
*'''WAITING''' (time between connection closed, and changing to LISTENING mode)
== Part 1: Enabling the sshd service. ==
