Running a FTP server is quite popular for sharing files over the Internet. But, the FTP protocol is not as secure as some may think. By default, each FTP user has a system shell account and when connecting to the FTP server, all usernames and passwords are transmitted in plaintext. That means anybody sniffing your packets can gain access to your FTP accounts. This guide is intended to provide a solution to both problems. Pure-ftpd with puredb allows you to have throttled FTP-only accounts and the ability to use SSL.
