This book is targeted at the users who already know the basics of Linux, who want to learn how to manage Linux-based networks or take their skills to the next level. This can either be for the purpose of supporting an all-Linux network or even a mixed environment. This book takes the reader through easier topics such as installing Debian, to the more advanced concepts such as subnetting. By the end of this book, you should have enough knowledge to set up a completely networked environment, including all the components that such a network should feature. If this excites you, then this book is definitely for you!

However, in this book we focus on real-world examples pertaining only to Linux. If your goal is to become certified with Cisco or obtain some other high-level certification, this may not be the best place for you. Here, it's all about practical examples, without focusing too much on the theory. While certification cram books are neat, in this book we get things done – the real things that you will be required to do if asked by your boss or client to implement a Linux network. If that's your goal, you're definitely in the right place.
