Query: Complete waste of time and money

Unlike Dennis Cartwright, I cannot recommend this book even after receiving the replacement CD. The replacement still will not boot, and using the floppy install I get the message, "No Red Hat CD-ROM found." Maybe if you already have Linux installed from some other better-written book you could use this book to learn about DNS, Sendmail, Apache, etc. but I sure wouldn't know. If you are a Linux newbie hoping to stumble your way through to some knowledge, this book will waste your time, money, hair, and fingernails. I would give it zero stars if I could.P.S. Check out the Coriolis web site time. They have links to errata for their books - this is a great idea! Unfortunately, the errata page for this book insists that there are no problems, no errata available, the book is perfect! HA! What a joke! O'Reilly books has nothing to fear from this competitor!
