Please don't buy this. The information contained within can be found in about 30 minutes of Googling around.I've been working with WRT54s for a few weeks, browsed a copy of this (hint: Google pdf) and found it be of zero value to me.Unfortunately I don't have a better recommendation as an alternative.you're swimming in murky waters if you start hacking access points, but unless your needs are quite basic, this book isn't going to help. If your needs are pretty basic, the documentation on the OpenWrt and the dd-wrt sites will probably tell you all you need to know.One strong suggestion: the hardware in these boxes changes frequently.if you're buying a device to play with, be very careful about the specific hardware version of what you get. Example: Asus' WL-500gp is a great box to use, but hardware version 2 of that box uses a different wireless chip that is currently unsupported (as of 12/2008).
This book is a great guide hacking your WRT54G. It covers a wide variety of topics and gives some good detail into each one without focusing on one topic more than it should.
The book is good at showing you how to take what is out there and apply it to what you have. (Anyone want a fried WRTSL54GS for cheap).
I was happy to see clear examples and pictures on building JTAG cables, GPIO points, and other pieces of hardware. I enjoyed the book quite a bit and wish it had been released a few months earlier for a project I was working on.
The frustrating part is when you make a mistake and have to go buy more parts. These were some things that took me a bit longer to research on my own and what I found required me to make several leaps of faith.
The fun part of hacking hardware is that you have something to hold when you are done. I appreciated the work Larry and Paul put into making this less of an issue.I'd love to see information on writing software for these devices in the future.
However, I'm starting to dig into developing applications for this platform and piecing things together off of the web can be a bit tedious.
In the book we learn the parts of a Linksys router; to be truthful, I had never thought about that. There are even several methods for increasing the radio output and or antenna modifications. Heavens knows, I have three or four sitting in the equipment closet from before we upgraded my home office to professional equipment. I don't personally plan to try to hardware hack my Linksys router tonight after finishing reading the book, but it is on the list. I think the most important contribution this book will make is to help people understand it is possible to change those innocuous Linksys boxes. If you are going to be installing wireless it is a good idea to read this book, a lot of the information applies regardless of what brand of equipment you select. This book in extensively researched, we learn how to set up DHCP, SAMBA even X Windows. There is a discussion about the OpenWrt team, without them, this would never be possible.It was a real eyeopener to learn how much people have done with the WRT54G, there are a number of choices in firmware, even semi-commercial choices such as Talisman which allows you to establish VPNs, hotspots, mesh and even SIP VoIP.
readers are cautioned this can get you into trouble, I know I ended up sending my FM pirate radio system to a missionary group in Africa because it was just too tempting and in an urban area the FCC will eventually get you. Talk about a blast from the past, brings back the old 8086/8088 days. After all, they are everywhere. U.S. There is a discussion about overcloking the router to make the processor run faster. It was dangerous then and it still is today. The biggest surprise for me was the use of a WRT54G ( with an adapter ) as a bluetooth scanner.My understanding is that the authors are going to offer a class, that sounds like a lot of fun. And as for me, I don't think I will ever look at a Linksys router in the same way ever again, from now on I will be wondering just exactly what is going on beneath the hood.
I would have given this book a 5 star rating but it unfortunately covers too much info about using the OpenWRT "White Russian" firmware instead of the new NVRAM replacement firmware called OpenWRT "Kamikaze". This is a great book for anyone interested in knowing all about the WRT54G series routers and how to hack them. The authors Paul and Larry from the popular "PaulDotCom Security Weekly" podcast did a great job explaining the inner workings of the router and also have some great tips on how to hack the firmware and hardware. In their defense though I acknowledge that at the time of print the OpenWRT "Kamikaze" stable version was finally released. But anyone needing to know all about the previous OpenWRT "White Russian" or the other optional firmware upgrades will definitely not be disappointed.I highly recommend buying this book anyway and also recommend their related website "[.]." for more valuable info about these awesome little routers.
