          <h2>What is Cockpit?</h2>

<blockquote><em>Cockpit is an interactive server admin interface. It is easy to use and very lightweight. Cockpit interacts directly with the operating system from a real Linux session in a browser. -<a href="https://github.com/cockpit-project/cockpit" target="_blank">https://github.com/cockpit-project/cockpit</a></em></blockquote>

</ol>

<h2>Applying the Certificates to Cockpit</h2>

<p>Per the Cockpit documentation, Cockpit will &quot;<em>use the last file with a .cert or .crt extension in alphabetical order</em>&quot; and the private key &quot;<em>must be contained in a separate file with the same name as the certificate, but with a .key suffix</em>&quot;</p>

<ol>
	<li>Download WinSCP <a href="https://winscp.net/eng/downloads.php" target="_blank">Download</a></li>
	<li>Extract WinSCP and run the executable</li>
	<li>Connect to the Cockpit host IP address via WinSCP</li>
	<li>Copy the exported .crt and .key files to the target host home/$USER/Documents directory</li>
	<li>Connect to the target host via SSH or console and run the following commands
	<div class="codeBlock"># copy the .crt file<br />
	sudo cp ~/Documents/*.crt /etc/cockpit/ws-certs.d/<br />
	# copy the .key file<br />
	sudo cp ~/Documents/*.key /etc/cockpit/ws-certs.d/<br />
	# restart cockpit service<br />
	sudo systemctl restart cockpit</div>
	</li>
