"Linksys WRT54G Ultimate Hacking" book

Do you like Linux-based embeded devices? Do you love security? Do you enjoy wireless technologies? Are you ready for new challenging software and hardware hacking projects? Then, the "Linksys WRT54G Ultimate Hacking" book from Syngress should be the next book on your bookcase. After several months of work and research, it is going to be published this month.

As the Technical Editor for this book, I'm sure you will enjoy playing with all the information and projects the authors, Paul Asadoorian and Larry Pesce, put into this book. The WRT54G (and related family of devices) is a highly functional and cheap device that can run the Linux OS and perform lots of different security functions: from being your wardriving box, main Internet gateway or VoIP PBX, to become your preferred pentesting device. Learn all about the WRT54G, and follow up future projects and updates on the accompanying Web site!

The Table of Contents can give you a good idea of what you can find inside this book. Start enjoying it right now through the sample chapter! (Chapter 3, "Using Third-Party Firmware")

Good posts,

i want to know your opinion about the wrt routers. I am thinking about to buy one, but i can't decide wich.

Which model do you recommend me to investigate with it?.

Is better to be only router or is there any possibility to have ADSL integrated.

Thanks! The best option based on its functionality and price is the WRT54GLv5 (Linux-based). The most advanced option is the WRTSL54GS, that includes a USB port. It seems this model is going to be replaced by the WRT350N: USB port, Giga-Ethernet and MIMO (N-draft).

Obviously, your decision must be based in what you want to get from it, such as if you need an ADSL port. Linksys has models that provide ADSL connectivity.

For fun, hacking and learning, the WRT54GL is more than enough. Enjoy it!

This is a very brief summary. I suggest you to read chapter 1, "WRT54G Fundamentals", that covers all the WRT54 models, all hardware differences, and even includes a buyer's guide for seven different user profiles ;)

Yo talk abot WRT54GLv5.
Where i can find v5. Is there any special reason for this version?. It is capable to run openwrt?

Sorry, it was a typo. You need a WRT54GL (most probably you will find the latest version, v1.1). It is based on Linux and runs OpenWrt.

The typo came because I do not recommend you to get a WRT54G v5, because it is not based on Linux, but on VX Works. Although nowadays you can run OpenWrt on it, it is much more limited from a HW perspective.

I am looking for a device that is able to run audit tools for wireless like aircrack, nmap, etc.

Like de fairuza firmware do

Do you think that with the WRT54GL i will be able to do this.

I want to have an audit device, instead having a laptop with this tools.

As you can see in the book ToC, chapter 2 covers multiple third-party firmwares, including the FairuzaWRT.

This version and OpenWRT work great in a WRT54GL, although if you want to put lot of SW inside (kismet, aircrack-ng, nmap,...) you will need more disk space. The SD card hack on chapter 7 is great if you don't want to buy one of the expensive WRT54G versions that include a USB port.

Chapter 6 is focused on using the WRT54G from a PenTest perspective, so it is for you :) Get the book, get a WRT54GL (or a few)... and enjoy during weeks!! ;)

Hi there is it possible to use any firmware to convert the wrt54gl into an adsl-2 router

Unfortunately the WRT54GL does not have a RJ-11 connector, therefore it doesn't have the hardware required to act as a direct ADSL router.

No matter what firmware you use, it cannot provide ADSL/ADSL-2 capabilities. You need a pure xDSL router together with the WRT54GL.
