'''Record steps, commands, and your observations in INVESTIGATION 1 in your OPS335 lab log-book'''

The default (and often the only way) to administer a Linux server is via SSH. Even if you work in a graphical Linux environment, it is very useful to open a terminal and use SSH to monitor and manage your VMs (you can resize the terminal window).

The SSH server should be installed and running in your VMs. If it's not installed - you can install '''openssh-server''' using yum.

After performing lab7 in OPS235, you should have a basic understanding of ssh and public/private key cryptography to create secure connections between servers.<br>

[[Image:ssh_connection_explained.png|thumb|center|600px|A diagram explaining how public / Private keys work. Another term to represent this process is called '''PKI''' (Public/Private Key Infrastructure) ]]

This needs to be generated on and used on your '''client''' machine (i.e. the user/machine you're connecting '''from''').

So far, this topic is generally a repeat of OPS235 lab7.
