Lesson 1

NIS Client Networking

Organizations want their networks to be powerful communication systems that are easy to use. A large network is not just a simple collection of computers that communicate with each other, it is a complex system that requires a well-thought out plan in order for it to function smoothly.
You can facilitate the use of a network by presenting users with consistent configuration and interfaces on all computers. For example, you could use the same username and password on all computers on your network. But, keeping consistent information on all hosts can be a daunting task if you edit each and every computer's configuration files. It is more efficient to have a central location for the information on a network.
The Network Information Service (NIS) allows you to do just this. You can provide authentication (usernames and passwords), hostnames, protocols, and many other types of information to computers from one or more servers. In this module, you will learn about the tools and files involved in configuring the client's use of NIS.

Learning objectives:
  1. Describe the Network Information System
  2. Obtain information about the network
  3. Describe the function and purpose of nsswitch.conf
  4. Use authconfig to configure an NIS client machine
  5. Edit configuration files for the NIS client manually
  6. Test the NIS client machine
The next lesson describes the Network Information System.
