What is Radius? Radius stands on Remote Authentication Dial in User Service, is an AAA protocol (Authentication, Authorization and Accounting), which control access to resources in the network data. Their use is widespread, especially among the ISP (Internet Service Provider). Usually used with Nas (Network Access Server) and the PPP protocol for Dial Up via modem. This is still used by many ISPs at this time.
Standard port is the radius of 1812 (for Authentication) and 1813 (for Accounting). It is used by Radius and FreeRadius Server Microsoft, Cisco and Juniper use port 1645 and 1646. Here's a list of servers that radius both open source and commercial. For the opensource: FreeRadius, OpenRadius, GNU Radius, CistronRadius. For the commercial: Microsoft Radius Server, Aradial Radius Server, Cisco Secure Access Control Server for Windows, etc..
What is FreeRadius? FreeRadius radius server that is quite popular in the open source world. Developed by Alan DeKok and Miquel van Smoorenburg in 1999. Previously, Miquel develop Cistron Radius, but then became inactive developed. FreeRadius be widely accepted and received support from the opensource community. Otherwise to supporting text file, supporting LDAP, SQL (MySQL, Oracle, PostgreSQL, MSQL, etc), and EAP. FreeRadius itself claimed quite fast, feature rich, reliable and scalable. Free Radius run on many platforms such as Windows OS family Linux / Unix, Mac OS, Sun Solaris.
Features of the Free Radius :

Features of the Free Radius :
- Having a high performance, support HA, Fail-Over.
- Feature rich, supporting many Operating System, EAP, Database, AAA functionality, Virtual Server, Proxy, etc..
- Modular, support addon / plugin addition, it can be implemented on the embedded system.
- Scalability, the high burden for supporting freeradius based on the maximum request and the maximum server (cpu).
