Linux-powered networking, Part 1: Build a DNS server with ISC BIND

Keith Robertson (keithrob@us.ibm.com), Software Engineer, IBM
Keith Robertson is an Advisory Software Engineer at IBM in Research Triangle Park, NC. He is pursuing a master's degree in computer networking at North Carolina State University in Raleigh, NC. His background includes experience with networking technologies and software-development techniques. He has a working knowledge of low-level telecom networking protocols (such as SIP and MEGACO) and IP networking management protocols (such as SNMP and ICMP). He is also skilled at C/C++ and the Java programming language. You can contact Keith at keithrob@us.ibm.com.

Summary:  The first in a three-part series, this tutorial shows you how to leverage Linux to get the most from your network. Specifically, you will learn how to install and run your own name server, in this case, Internet Systems Consortium (ISC) BIND. Sample code and configuration files are provided throughout to aid understanding.

About this tutorial

Running your own name server such as ISC BIND has many advantages, including redundancy and speed. Your network will also become more resilient to upstream name server outages. You are also likely to see an improvement in response time to name server queries. In addition, you have the ability to name the devices attached to your network (such as printer1.somedomain.com).

This tutorial is the first in a three-part series that demonstrates how to leverage Linux to get the most from your network. This tutorial describes how to set up DNS with Internet Systems Consortium (ISC) BIND in order to name the devices on your network. This tutorial also shows how to run the name server securely.


Prerequisites

The network described in this tutorial is intentionally small so that you can easily duplicate the examples on a home or lab network. For this setup, I used a typical home broadband router with a built-in firewall. The Linux distribution is Fedora Core 1, but the setup described here works on other Linux distributions or UNIX® variants, such as AIX®, Solaris, and HP-UX.

The ISC software is free and you can get it in a number of ways. I recommend that you get a precompiled version (via RPM, for example) from your Linux vendor's FTP mirror. You can also download the source from the Internet Systems Consortium.

This tutorial is intended for readers with moderate UNIX or Linux familiarity and an understanding of basic IP networking concepts.
