Overview

Introduction

The Name Resolution module provides you with the instructions and devices to develop your hands on skills in the following topics.

  • Work with Host Names
  • Work with the HOSTS File
  • Test Name Resolution
  • Examine DNS Configuration
  • Configure a DNS Server
  • Test DNS
  • Install and configure WINS

Exercise 1 - Work with Host Names

In this exercise, you will explore different ways of addressing machines by a friendly name rather than an IP address. You will discover what your host name is and attempt to ping yourself and a remote device by host name.

Exercise 2 - Work with the HOSTS File

The HOSTS file is static text file used by a computer to resolve host names to its numeric Internet Protocol (IP) address. This text file found on the hard drive of the local computer predates Domain Name System (DNS) now widely used for resolving names in the local network and the global Internet.

In this exercise you will edit a HOSTS file to place a host record into it, and test that it works.

Exercise 3 - Testing Name Resolution

In this exercise, we will disable DNS and then NetBIOS to observe the effects on name resolution.

Exercise 4 - Examining Client DNS Configuration

In this exercise, you will look at the client and server settings that enable DNS.

Exercise 5 - Configure a DNS Server

In this exercise, you will configure a DNS Server to resolve name queries for your Linux device. The BIND DNS Server is already installed but you need to configure it with zone records.

Exercise 6 - Testing DNS

In this exercise, you will test the DNS configuration using ping and nslookup.

Exercise 7 - Installing and Configuring WINS

In this exercise, you will learn how to use Windows Internet Name Service (WINS).
