The purpose of this lab is to change the server name and setup your server to use a static ip address.
<br>
<span class="note">In the ip addresses below:<br>
Replace <?=$octet1?> with the 1st octet in your network.<br>
Replace <?=$octet2?> with the 2nd octet in your network.<br>
Replace <?=$octet3?> with the 3rd octet in your network.<br>
Replace <?=$octet4?> with the 4th octet of your server's IP address.<br>
<b>This will happen automatically if your enter your server's ip address and gateway below.</b>

<li>Ensure your server has three network adapters:
<ol>
<li>Open a terminal window.</li>
<li>Enter the command <kbd class="copyText">ip -4 a</kbd>.
You should see three network adapters.
<br><b>If you do, then you can skip the rest of step 2.</b>
<br>If you do not, you need to add a host-only adapter to your server:
<ol>
<li>Shutdown your server.</li>
<li>Open the VM settings.</li>
<li>Select Network from the left pane.</li>
<li>Select the <b>Adapter <span style="text-decoration: underline">2</span></b> tab.</li>
<li>Check <b><span style="text-decoration: underline">E</span>nable Network Adapter</b>.</li>
<li>Select <b>Host-only Adapter</b> in the <b><span style="text-decoration: underline">A</span>ttached to</b> dropdown.</li>
<li>Click <b>OK</b>.</li>
<li>Configure your Host-only Adapter:
<ol>
<li>Restart your server.</li>
<li>Open a terminal window.</li>
<li>Enter the command <kbd class="copyText">ip -4 a</kbd>.
You should see three network adapters. If you do not then you need to contact me for help.
</li>
<li>Note the name of adapter 3 and enter it here (if different): <input type="text" name="adapter2" id="inp_adapter2" onInput="CheckAddresses(this);" maxlength="8" style="width:4em;" value="enp0s8"> <span class="note">Mine was <b>enp0s8</b>.</span></li>
