I am doing a project in network mesh, wireless mesh. After making the implementation of my network, I want to do authentication and security of my network using Radius. But I have no information of this side and I found many documents that I do not understand. Please help me to find a clear document and without difficulty. I want to do the Radius on two machines: a server and a client. What are the commands to type to each machine.

Start with this page on the wiki: http://freeradius.org/doc/

Install FreeRADIUS on one system. Then use radtest as a client to test your server installation.
