Installation Of Free. RADIUS On Cent. OS And Ubuntu.

Free. RADIUS is a modular, high performance free RADIUS suite developed and distributed under the GNU General Public License on its second version. It is a free and open source tool. The Free. RADIUS Suite includes a RADIUS server, a BSD- licensed RADIUS client library, a PAM library, an Apache module, and numerous additional RADIUS related utilities and development libraries. In this article we will show you how you can install and setup the Free. Readius tool in a cent. OS and Ubuntu systems.

Features of Free. Radius. Free. RADIUS is the most popular open source RADIUS server and the most widely deployed RADIUS server in the world.

It supports all common authentication protocols, and the server comes with a PHP- based web user administration tool called dialupadmin. Modules included with the server core support LDAP, My. SQL, Postgre. SQL, Oracle, and many other databases. It supports all popular EAP authentication types, including PEAP and EAP- TTLS. Free. RADIUS is also the only open source RADIUS server to support virtual servers. The use of virtual servers means that complex implementations are simplified and ongoing support and maintenance costs for network administrators are greatly reduced. Installation of Free.

Radius. For the installation we will not use the same command with cent. OS and Ubuntu. So with Cent.

OS 5 we use the following command: yum install freeradius. OS 6 we use the following command: yum install freeradius freeradius- mysql freeradius- utils mysql- server - y. While with Ubuntu we use the following command: apt- get install freeradius freeradius- mysql freeradius- utils mysql- serverthen we will setup the My. SQL by using the following commands: For Cent. OS: service mysqld start. For Ubuntu: service mysql start.

And to set a new password and the security settings we will use the following commands: /usr/bin/mysql. And to create the Radius database we will use the following command: mysql.

You will be convinced that you installation is working well if you see something like: “rad. This tool is widely used for Enterprise Wi- Fi and IEEE 8. X network security, particularly in the academic community, including eduroam.
