Control and track the usage of network resources by using the most popular RADIUS server today

Description

The Open Source pioneers have proved during the past few decades that their code and projects can indeed be more solid and popular than commercial alternatives. With data networks always expanding in size and complexity FreeRADIUS is at the forefront of controlling access to and tracking network usage. Although many vendors have tried to produce better products, FreeRADIUS has proved over time why it is the champion RADIUS server. This book will reveal everything you need to know to get started with using FreeRADIUS. FreeRADIUS has always been a back-room boy. It's not easy to measure the size or number of deployments world-wide but all indications show that it can outnumber any commercial alternatives available. This essential server is part of ISPs, universities, and many corporate networks, helping to control access and measure usage. It is a solid, flexible, and powerful piece of software, but can be a mystery to a newcomer. FreeRADIUS Beginner's Guide is a friend of newcomers to RADIUS and FreeRADIUS. It covers the most popular Linux distributions of today, CentOS, SUSE, and Ubuntu, and discusses all the important aspects of FreeRADIUS deployment: Installing, configuring and testing; security concerns and limitations; LDAP and Active Directory integration. It contains plenty of practical exercises that will help you with everything from installation to the more advanced configurations like LDAP and Active Directory integration. It will help you understand authentication, authorization and accounting in FreeRADIUS. It uses many practical step-by-step examples, which are discussed in detail to lead you to a thorough understanding of the FreeRADIUS server as well as the RADIUS protocol. A quiz at the end of each chapter validates your understanding.Not only can FreeRADIUS be used to monitor and limit the network usage of individual users; but large deployments are possible with realms and fail-over functionality. FreeRADIUS can work alone or be part of a chain where the server is a proxy for other institution's users forwarding requests to their servers. FreeRADIUS features one of the most versatile and comprehensive Extensible Authentication Protocol (EAP) implementations. EAP is an essential requirement to implement enterprise WiFi security. FreeRADIUS Beginner's Guide covers all of these aspects.

This book covers how to configure the freeradius server in a really easy way, in the ubuntu authentification there are some little changes that must be done for it to work but nothing a regular ubuntu user can't solve.

Great general overview of the Ins and Outs of FreeRADIUS - this book has been very helpful in my FreeRADIUS setup

ArtFan Mar 11, 2016

Although this book deals with Freeradius-2.x, the vast majority of it is also applicable to 3.0 and even for those pieces that have changed you will be able to figure it out with the knowledge you get from the book. Which means that if you need to learn how to administer recent versions, this book works. It explains how the radius protocol works, how freeradius implements it, and the various pieces and moving parts, what they do, how to make use of them. It explains this in a practical manner, as a tutorial with exercises, that starts from the ground and builds piece-by-piece so that you acquire a solid understanding. The author explains things in clear, effective language. You learn without being distracted by unnecessary jargon or irrelevant topics. The reason I got the book was because I needed such a tutorial and was unable to find something similar online. And I'm glad I did, it gave me what I needed.

The book "'FreeRADIUS Beginner's Guide -' Manage your network resources with FreeRADIUS"' by Dirk van der Walt has set itself a bold goal: to transform an ordinary Unix/Linux system administrator from a 'Zero' to a 'Hero' in the topic of Authentication, Authorisation and Accounting with FreeRADIUS. The book is in a very modest price range and available in traditional printed and also an eBook version.From my own experience, getting in first contact with the RADIUS protocol in general and FreeRADIUS in particular can be a dreadful exercise: there are many complex concepts to grasp and huge configuration files to master; and plenty of opportunity to break things if you touch the configuration without knowing the do's and don'ts. The FreeRADIUS software package has ample documentation in the form of man pages and comments in configuration files. What was sorely missing ' up until now ' was documentation that would take an innocent reader by the hand and show him the wonders of RADIUS without too much confusion.Dirk's book certainly achieves this goal, and more. It dives straight into the matter, touches the RADIUS specification only as much as is needed to understand the software that delivers it. The reader learns how easy it is to get to the 'Hello, world!' equivalent of RADIUS ' the first successful authentication, an Access-Accept packet. From then on, the book builds on the milestones achieved by the reader and adds more and more features and complexity. Near the end of the book, the reader has all the required knowledge to run his own little hotspot, a federated 'single-sign-on domain' based on RADIUS or even be part of a large roaming consortium.Being heavily involved in RADIUS myself, as the lead R&D engineer for the 'eduroam' roaming consortium in Europe, and as lecturer on the topic of Secure Network Admission at the University of Luxembourg, I was amazed how often I found myself thinking 'Right, couldn't have said it better' when the author explained some of the particularly hairy concepts ' EAP with outer identity just being one example.Of course, there are always those few little things everyone likes to do a bit differently; I'm very much a compile-from-source person and was slightly disappointed to read that the author rather encourages his readers to use distribution packages or build their own RPMs/DEBs. Then again, the target audience is starting from zero, and adding "'compile your own"' to the stack of things to learn is probably asked a bit much. Another question of taste is the client to use for testing the more complex authentication mechanisms ' the book uses a GUI client, JRadiusSimulator, while I very much prefer 'eapol_test' from the wpa_supplicant software suite. It can be so nicely scripted and is as flexible as a Swiss army knife ' perfect for Nagios monitoring. In my humble opinion, it would have deserved a significant mention. Lastly, there is a nagging little oversight when it comes to the description of proxying on page 250: Proxying, when done in combination with mutually authenticating EAP methods and with anonymous outer identities doesn't expose usernames nor credentials to the roaming partner. The book doesn't make that aspect overly clear. Then again, peeking at the title, this topic is way advanced and few people will get to a point in their RADIUS life where they would need it.Summarising, I can highly recommend this book as a starter to get into FreeRADIUS. I'm sure the FreeRADIUS users' mailing list would see much less traffic on basic operational and conceptual questions if everyone were to read this book. If you need to get acquainted with FreeRADIUS, do yourself a favour and grab a copy.

This is a great book for starting off with Free Radius with very little understanding of how it functions to begin with.
