Title: Save your money.
Review: David Kearns, the actual author of this hound, has produced another of his yawners. He's pointlessly snide and irritating - viz, his insistence on "octet" where anyone else would call eight bits a "byte"- but at least he's incomplete: he essentially ignores Linux, gives the cold-shoulder to Unix, and is flat wrong in his limited knowledge of MacOS. This falls somewhat short of most definitions of "Complete", especially with the rapid growth of Linux as a low-cost network server alternative. If you're new to networking, you may get the impression this book is over your head. It isn't. It is incomplete, irritating, and wrong. Keep looking.
