What is proFTPD

Share Button

ProFTPD is a free and open source FTP server. Its authors announce it as powerful and perfectly secure. ProFTPD is the most popular file transfer protocole in Unix-like environments today.

It is distributed under the terms of the GNU GPL license.

ProFTPD is also well documented, most configurations would be similar to the tutorials provided with the software. Its unique configuration file, proftpd.conf, uses Apache-like syntax to homogenize configuration files. However, the include directive allows you to split configuration directives into different files for more complex cases.

The software makes it possible to configure several virtual FTP servers and has the possibility of being used in a dedicated environment (chroot). It can be launched as a daemon or as an inetd service. Finally, ProFTPD is IPv6 compatible.

Its architecture is modular, which has made it possible to write extensions for the support of SSL / TLS cryptography (FTPS protocol) and the extension of authentication via RADIUS, LDAP or SQL databases.

The SQL module also allows database storage of the operations performed on the FTP server.

The version 1.3.2 also supports the SFTP and SCP protocols from SSH via the mod_sftp module.
