Introduction

The Red Hat Enterprise Linux Introduction to System Administration contains introductory information for new Red Hat Enterprise Linux system administrators. It does not teach you how to perform a particular task under Red Hat Enterprise Linux; rather, it provides you with the background knowledge that more experienced system administrators have learned over time.

This guide assumes you have a limited amount of experience as a Linux user, but no Linux system administration experience. If you are completely new to Linux in general (and Red Hat Enterprise Linux in particular), you should start by purchasing an introductory book on Linux.

Each chapter in the Red Hat Enterprise Linux Introduction to System Administration has the following structure:

- Generic overview material - This section discusses the topic of the chapter without going into details about a specific operating system, technology, or methodology.

- Red Hat Enterprise Linux-specific material - This section addresses aspects of the topic related to Linux in general and Red Hat Enterprise Linux in particular.

- Additional resources for further study - This section includes pointers to other Red Hat Enterprise Linux manuals, helpful websites, and books containing information applicable to the topic.

By adopting a consistent structure, readers can more easily read the Red Hat Enterprise Linux Introduction to System Administration in whatever way they choose. For example, an experienced system administrator with little Red Hat Enterprise Linux experience could skim only the sections that specifically focus on Red Hat Enterprise Linux, while a new system adminstrator could start by reading only the generic overview sections, and using the Red Hat Enterprise Linux-specic sections as an introduction to more in-depth resources.

While on the subject of more in-depth resources, the Red Hat Enterprise Linux System Administration Guide is an excellent resource for performing specic tasks in a Red Hat Enterprise Linux environment. Administrators requiring more in-depth, factual information should refer to the Red Hat Enterprise Linux Reference Guide.

The Red Hat Enterprise Linux System Administration Guide contains information on how to customize your Red Hat Enterprise Linux system to fit your needs. If you are looking for a step-by-step, taskoriented guide for conguring and customizing your system, this is the manual for you. This manual discusses many intermediate topics such as the following:

-  Setting up a network interface card (NIC)

- Performing a Kickstart installation

- Configuring Samba shares

- Managing your software with RPM

- Determining information about your system

- Upgrading your kernel

This manual is divided into the following main categories:

- Installation-Related Reference

- File Systems Reference

- Package Management

- Network Cofinguration

- System Configuration

- System Monitoring

This guide assumes you have a basic understanding of your Red Hat Enterprise Linux system.
