ProFTPD is part of Extra Packages for Enterprise Linux (<a href="http://www.hackthesec.co.in/search/label/EPEL_Repo" style="color: #999999; text-decoration: none;">EPEL</a>), which is a community repository of non-standard packages for the <a href="http://www.hackthesec.co.in/search/label/EPEL" style="color: #999999; text-decoration: none;">RHEL</a> distribution. First, we’ll install the EPEL repository:</div>
