BSDRadius

BSDRadius is a RADIUS server written in Python, targeted for use in Voice over IP (VoIP) applications. The main sponsor of the project is Data Tech Labs. Their first public release was in 2006 and the latest in 2007. It's freely available via the BSD license for BSD systems, Linux, and other platforms. For support, you'll find online documentation and mailing list.

The BSDRadius server is streamlined for use with the common VoIP protocols (SIP and H.323) and authentication methods (CHAP and Digest), rather than supporting the whole range of networking protocols and authentication methods. This optimization reduces the processing overhead and code size of server. It can handle the high amount of AAA requests, large databases, and timely responses required by VoIP.

IBS

IBS is an accounting and billing solution for ISPs with an integrated RADIUS server that supports prepaid VoIP, dial-up, and LAN services. It's freely available with the GNU General Public License (GPL) and can run on Unix-like systems. The first public release was in 2003, and the latest in 2008. The server is written in Python and the web interface in PHP4. For support, there's an online manual and discussion forum.

The IBS server supports LAN accounting using the PPTP protocol, prepaid VoIP with interactive voice response (IVR) on the Cisco and Quintum platforms, and traffic shaping for LAN clients. It also features an integrated mail system and an Apache authentication module. For optimum performance, IBS implements a thread pool, event scheduler, and a database connection pool. IBS works with products from Cisco, Portmasters, Multiport, and Quintum Tenor.

Radiance

Radiance is a small project headed by Iagu Networks. Since the RADIUS server is written in Perl, its highly portable. It can run on most POSIX systems, such as Unix, Linux, Mac OS X, and BeOS. For support there's a small online document.

Eric Geier is the founder of NoWiresSecurity, which helps businesses easily protect their Wi-Fi networks with the Enterprise mode of WPA/WPA2 encryption by offering an outsourced RADIUS service. He is also a freelance tech writer, and has authored many networking and computing books for brands like For Dummies and Cisco Press.
