“FTP is a very insecure protocol because all passwords
and all data are transferred in clear text. By using TLS, the whole
communication can be encrypted, thus making FTP much more secure.
This article explains how to configure PureFTPd to accept TLS
sessions on a CentOS 5.5 server.
“1 Preliminary Note: You should have a working PureFTPd setup on
your CentOS 5.5 server, e.g. as shown in this tutorial: Virtual
Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth
Management) On CentOS 5.3 (works on 5.5 as well).”
