Overview of this book

CentOS is derived from Red Hat Enterprise Linux (RHEL) sources and is widely used as a Linux server. This book will help you to better configure and manage Linux servers in varying scenarios and business requirements. Starting with installing CentOS, this book will walk you through the networking aspects of CentOS. You will then learn how to manage users and their permissions, software installs, disks, filesystems, and so on. You’ll then see how to secure connection to remotely access a desktop and work with databases. Toward the end, you will find out how to manage DNS, e-mails, web servers, and more. You will also learn to detect threats by monitoring network intrusion. Finally, the book will cover virtualization techniques that will help you make the most of CentOS.

Introduction

In this chapter, you'll find recipes that cover working with BIND in various capacities to manage your domain infrastructure better. You'll learn how to configure BIND as a resolving DNS server capable of caching lookup results which can help reduce latency, and also how to configure BIND as an authoritative DNS server to provide authoritative responses publicly for your domain or for resources on your private intranet. Also discussed are handling reverse lookup requests and ensuring your resources remain accessible by configuring redundant, secondary authoritative DNS servers that perform master/slave-style transfers of zone records. Finally, you'll learn how to set up and use rndc, a very useful administration client for BIND servers.
