There is a reason that O'Reilly pulled this book out of print after only six months, and has not even bothered to try to fix it and rerelease it. The book was basically a commercial for the company that the author ran. It read as if it hadn't been edited, with spelling and grammar mistakes, and even incorrect graphics (at one point, the text of the book and the caption of the graphic refer to the Linux install probing for a video card, while the picture is a screen shot of the "Configure networking" screen of the setup). The code included on the CD was so buggy that it would not even run without a lot of fixing on the user's part.

In short, don't get this book.
