Introduction

This book is about SUSE Linux Enterprise Server 10. With SUSE Linux Enterprise Server 10, Novell launched the best professional Linux server operating system ever, based on work that started more than 10 years ago by the people from SUSE in Germany. With this software, Novell has managed to create an easy-to-manage yet very complete, robust, and versatile operating system that can perform a broad range of tasks everywhere within a company.

This book is meant as a complete work, helping people who have never worked with Linux before to set up a functional server while also helping advanced administrators of SUSE Linux by providing some details about new functionality and about some of the most complex parts of SUSE Linux.

Who This Book Is For

This book was written for new as well as experienced administrators of SUSE Linux Enterprise Server. The first part of the book contains some introduction-level material that new administrators will like, and the last part of the book contains some advanced information aimed at experienced Linux administrators. Everything in between was written to help the reader set up all the important services on SUSE Linux Enterprise Server. Because of its broad approach, this book is an indispensable reference guide for everyone administrating SUSE Linux Enterprise Server.

How This Book Is Structured

This book is divided into four parts, with a total of no less than 35 chapters.

Part 1: Getting Familiar with SUSE Linux Enterprise Server

As the name suggests, this part is for people who are new to SUSE Linux Enterprise Server and even for people who haven't worked with Linux before. In this part, you'll learn how to install SUSE Linux Enterprise Server and understand the way it is structured. This part includes information about working from the GNOME graphical user interface, working with the file system, and working with the management utility YaST.

Part 2: Administering SUSE Linux Enterprise Server

In this part, you'll get in-depth information about generic SUSE Linux administration tasks. This part starts with a discussion of Linux users and groups management. This is followed by a chapter about working with file and directory permissions. Next, two chapters cover all the important tasks related to managing the file system. Then you'll learn how to manage software. Next, I'll cover system initialization, process management, and system logging.

Part 3: Networking SUSE Linux Enterprise Server

In this part, you'll get detailed information about the most important network services and how to set them up in a SUSE Linux Enterprise Server environment. At the start of this part, you'll learn how to configure the network interface. This part covers popular services such as Apache, DNS, DHCP, Postfix, and Squid, as well as some essential network functionality such as remote access. In addition, this part covers setting up an LDAP server and managing cryptography. Finally, I'll discuss the topics of remote access, NTP time synchronization, and the CUPS print server.

Part 4: Advanced SUSE Linux Enterprise Server Configuration

In this part of this book, I'll discuss some of the more advanced tasks. The chapters in this part cover tasks that are not essential but that make your SUSE Linux Enterprise Server a lot more useful. You will find chapters about tasks that will make you a better system administrator, such as kernel and hardware management, shell scripting, optimization, troubleshooting, and firewall configuration. Also, I'll cover some new technologies such as Heartbeat clustering, AppArmor application security, and Xen virtualization.
