This book is about "the way things work." It's a quick, straight to the point reference for various networking concepts, targeted at the middle-level network engineer. Instead of memorizing tidbits of information to pass a test, gain a real understanding about the protocols and concepts you need to use. See Also: http://OmniTraining.net/networkninja
After reading Network Ninja, you will:
Understand the protocols you work with, in a manner that actually makes them useful for solving real-world problems.
Be able to configure a switch, router, or OS, from any vendor, with little effort -- because you will understand what you're doing, not just one vendor's way of doing it.
Use your knowledge to explain previously mysterious phenomena.
Explain these concepts to junior network engineers, and become their mentor.
