The FreeRADIUS Project

FreeRADIUS includes a RADIUS server, a BSD licensed client library, a PAM library, and an Apache module. In most cases, the word FreeRADIUS refers to the RADIUS server.

FreeRADIUS is the most widely deployed RADIUS server in the world. It is the basis for multiple commercial offerings. It supplies the AAA needs of many Fortune-500 companies and Tier 1 ISPs. It is also widely used in the academic community, including eduroam. The server is fast, feature-rich, modular, and scalable.

The server has reached a stable Version 2.1.12 (sig) , with incremental improvements added in every release.

Recent News

2011.09.30 Version 2.1.12 (sig) has been released. The focus of this release is stability.

Feature improvements

Updates to dictionary.erx, dictionary.siemens, dictionary.starent, dictionary.starent.vsa1, dictionary.zyxel, added dictionary.symbol
Added support for PCRE from Phil Mayers
Configurable file permission in rlm_linelog
Added "relaxed" option to rlm_attr_filter. This copies attributes if at least one match occurred.
Added documentation on dynamic clients. See raddb/modules/dynamic_clients.
Added support for elliptical curve cryptography. See ecdh_curve in raddb/eap.conf.
Added support for 802.1X MIBs in checkrad
Added support for %{rand:...}, which generates a uniformly distributed number between 0 and the number you specify.
Created "man" pages for all installed commands, and documented options for all commands. Patch from John Dennis.
Allow radsniff to decode encrypted VSAs and CoA packets. Patch from Bjorn Mork.
Always send Message-Authenticator in radtest. Patch from John Dennis. radclient continues to be more flexible.
Updated Oracle schema and queries
Added SecurID module. See src/modules/rlm_securid/README

Bug fixes

Fix memory leak in rlm_detail
Fix "failed to insert event"
Allow virtual servers to be reloaded on HUP. It no longer complains about duplicate virtual servers.
Fix %{string:...} expansion
Fix "server closed socket" loop in radmin
Set ownership of control socket when starting up
Always allow root to connect to control socket, even if "uid" is set. They're root. They can already do anything.
Save all attributes in Access-Accept when proxying inner-tunnel EAP-MSCHAPv2
Fixes for DHCP relaying.
Check certificate validity when using OCSP.
Updated Oracle "configure" script
Fixed typos in dictionary.alvarion
WARNING on potential proxy loop.
Be more aggressive about clearing old requests from the internal queue
Don't open network sockets when using -C

2010.05.21 - A Development Roadmap is announced

As part of the continued growth of the server, we are actively looking for sponsors for new features. New projects include support for 3GPP2, Windows ports, etc.

2009.09.09 Version 1.1.8 (sig) has been released. The focus of this release is security.

Feature Improvements

None

Bug Fixes

Fix crash (memcpy with length -1) when invalid Tunnel-Password attributes are received.

2009.07.20 We have worked with MySQL to create two white papers on MySQL scalability and MySQL cluster. They are now available:

Delivering Scalable & Highly Available AAA Services

This white paper discusses the concepts of current data storage solutions for Authentication, Authorization and Accounting (AAA) environments and their potential limitations as network use grows and services become more dynamic.

The paper then presents an alternative deployment scenario based on the FreeRADIUS Server and MySQL Cluster serving as the back-end AAA database, providing an infrastructure for high growth and availability, with low complexity. A sizing study and user case study are presented to demonstrate how the solution performs in real-world FreeRADIUS environments

Deployment Guide: FreeRADIUS with the MySQL Cluster Database

This Guide documents a best-practice approach to configuring and testing a FreeRADIUS server deployed with the MySQL Cluster database storage engine serving as the back-end data store for user and accounting data. Deployment topologies and configurations are presented, enabling users to quickly and simply replicate the solution in their own environment.
