FreeRADIUS is the premiere open source RADIUS server. While detailed statistics are not available, we believe that FreeRADIUS is well within the top 5 RADIUS servers world-wide, in terms of the number of people who use it daily for authentication. It scales from embedded systems with small amounts of memory, to systems with millions of users. It is fast, flexible, configurable, and supports more authentication protocols than many commercial servers.

The server is released under the GNU General Public License (GPL), which means that it is free to download and install.

The FreeRADIUS Server Project

The FreeRADIUS Server Project encompasses more than just a RADIUS server. The related software includes a PAM authentication module, and an Apache 1.3 and 2.0 authentication module. The server comes with a PHP-based web user administration tool, called dialupadmin.

The RADIUS server has more features and is more flexible than any other free software RADIUS server, and many commercial servers. Most commercial servers are distributed as a "base" system ($), and an "enhanced" version ($$) with more features. FreeRADIUS has all the features of a commercial "enhanced" server, without the associated cost.

In it simplest form, the server is similar to Livingston's 2.0 server. Many configuration files are similar, and the general operation of the server should be familiar to anyone who has used a variant of the Livingston server. FreeRADIUS can be extended significantly from this simple form, however. There are many modules and configuration files which have no equivalent in older RADIUS servers. These new features permit FreeRADIUS to work within complex systems, and environments which require high performance.

To support the demanding requirements of a modern RADIUS server, FreeRADIUS features more than 50 vendor-specific dictionary files. It ships with support for LDAP, MySQL, PostgreSQL, Oracle databases. It supports EAP, with EAP-MD5, EAP-SIM, EAP-TLS, EAP-TTLS, EAP-PEAP, and Cisco LEAP sub-types. It supports proxying, with fail-over and load balancing. It has reached a stable 1.0 release, with incremental improvements being added and tested daily. In short, it is a powerful, fast, and complex RADIUS server which is compatible with the latest network protocols and practices, and is well suited for deployment in any size network.

About FreeRADIUS

FreeRADIUS is one of the most modular and feature-rich RADIUS servers available today. It has been written by a team of developers who have decades of collective experience in implementing and deploying RADIUS software, in software engineering, and in Unix package management. The product is the result of synergy between many of the best-known names in free software-based RADIUS implementations, including several developers of the Debian GNU/Linux operating system, and is distributed under the GNU GPL (version 2).

The FreeRADIUS server is being used all over the world in large scale installations comprising multiple radius servers with thouands of users and millions of sessions.
