Pure FTP Server is a fast, production quality, standards-conformant FTP server based on Troll-FTPd. Pure FTP Server has no known vulnerability, it is trivial to set up, and it is especially designed for modern kernels.

Features include PAM support, IPv6, chroot()ed home directories, virtual domains, built-in 'ls', FXP protocol, anti-warez system, bandwidth throttling, restricted ports for passive downloads, an LDAP backend, XML output, and more.

Beginners can install a Pure-FTPd server in 5 minutes. It can be as simple as installing the package, typing "pure-ftpd &" and... that's all. You already have a running server, and clients can start to connect.

There's no need to review any long and complex configuration file, where possible mistakes could have security and reliability implications. Pure-FTPd uses simple command-line switches to enable the features you need.

You can limit the number of simultaneous users, limit their bandwidth to avoid starving your ADSL or cable-modem link, hide system files (chroot), have upload/download ratios, and moderate new uploads.

Custom messages can be displayed at login-time (even changing fortune files) and when an user enters a new directory. Also, to avoid your disks being filled up, you can defined a maximal percentage, and new uploads will be disallowed once this percentage is reached.

The FXP (server-to-server) protocol is implemented. It can be available for everyone, or only for authenticated users.

Kiddies are using common brute-forcing tools that are trying to discover hidden directories. Pure-FTPd provides a protection against this. Anonymous access is secure by default. For instance, users can't access dot-files (.bash_history, .rhosts, ...) unless you explicitely enable this.

And to watch who's doing what, the pure-ftpwho command shows a table with currently active sessions, how much bandwidth is taken by every user, what files they are uploading or downloading, where they are coming from, etc.
