Radius: Securing Public Access to Private Resources
I read a lot of books, some of them are inspiring, entertaining and relevant. Some are dull, overly terse and yet still useful; The O’Reilly Radius book is more akin to bad dental surgery.
What really annoys me is that I can’t think of a better way of presenting such as dry topic, the book provides detailed coverage that is just as easy to read and understand (and as fascinating) as the original RFC version. It then introduces the basic uses of FreeRadius.
If you need to learn about RADIUS I’d suggest the RFCs and the man pages that come with your server instead of this title; and spend the saved money on caffeine, you may well need it!
