ProFTPD is part of Extra Packages for Enterprise Linux (<a href="http://www.hackthesec.co.in/search/label/EPEL">EPEL</a>), which is a community repository of non-standard packages for the <a href="http://www.hackthesec.co.in/search/label/EPEL">RHEL</a> distribution. First, we’ll install the EPEL repository:</div>
