<li>Make <u>certain</u> that you are in your centos you are NOT logged in as root!''' (you have been warned!)</li>
<li>To generate a keypair (public/private keys), issue the following command: <b><code><span style="color:#3366CC;font-size:1.2em;">ssh-keygen</span></code></b></li>
<li>Press ENTER to accept the default, then enter a pass-phrase used to establish your identity, and re-enter the pass-phrase to verify.<br><br>The output should appear similar as what is shown below:</li>
<li>You will then be prompted for a pass-phrase. The pass-phrase must be entered in order to use your private key. Pass-phrases are more secure than passwords and should be lengthy, hard to guess and easy to remember. For example one pass-phrase that meets this criteria might be "seneca students like fish at 4:00am". Avoid famous phrases such as "to be or not to be" as they are easy to guess. It is possible to leave the pass-phrase blank but this is dangerous. It means that if a hacker were able to get into your account they could then use your private key to access other systems you use.<br><br></li>
<li>Now issue the command <b><code><span style="color:#3366CC;font-size:1.2em;">ssh-copy-id -i ~/.ssh/ ops235@centos3</span></code></b></li>
<li>When prompted for password, enter OPS235's root password></li>
<li>Try using ssh to now log into your '''centos3''' VM <u>from</u> your '''centos2''' VM. What happens? Were you required to use your pass-phrase?</li>
<li> Issue the '''hostname''' command to verify that you are successfully logged into your '''centos3''' VM.</li>
