IntroductionIntroductionWhat Is Covered in this Book

This book is divided into 13 chapters. Each chapter builds on the ones that have come before it.

Chapter 1 explores just what the Novell Linux Desktop is and why you should consider it.

Chapter 2 explains how to install Novell Linux Desktop. It also looks at ways to update it with service packs and keep it current.

Chapter 3 explains the graphical interfaces. Two graphical desktop environments, GNOME and KDE, are included with NLD, and you can choose either or both with which to interact.

Chapter 4 introduces the command line—a source of great power in Linux—and introduces you to the most popular utilities that can be run from it.

Chapter 5 introduces Yet Another Setup Tool (YaST). This interface simplifies configuration settings and provides a unified interface for many administrative tasks.

Chapter 6 looks at hardware devices, such as printers, and how NLD interacts with them.

Chapter 7 explains how NLD works with filesystems.

Chapter 8 explains the files that exist in NLD and how to create and work with them.

Chapter 9 discusses Boot, Initialization, Shutdown, and Runlevels.

Chapter 10 focuses on Linux administration and the tasks you will likely face on a regular basis.

Chapter 11 looks at networking and how NLD interacts with other operating systems.

Chapter 12 introduces security.

Chapter 13 discusses how NLD interacts with other environments and how to use it in the real world.What this Book Is Not

This book is not designed to be a programmer's guide or focus on such topics as kernel tweaking. Those are not part of the normal administrators role and thus notincluded in an Administrator's Handbook. This is not a reference work for network theory, protocols, or architectures.

This book focuses on the implementation of Novell Linux Desktop and the administration of it after that implementation.

    check out YaST

    Novell offers its own version of linux for the desktop, and Dulaney explains how to administer it. Perhaps the most distinctive aspect is its YaST [Yet another Setup Tool]. Readers experienced in unix will recognise parallels with AIX's SMIT. Here, YaST lets a sysadmin who might be inexperienced with the linux command line cope with the complexity. By hiding it behind a user interface, that can be either terminal based or X Windows based graphical mode. YaST has a simple and useful grouping of typical common sysadmin tasks. Notably installing and removing software and patches. But it's not just for software. YaST is shown to handle hardware configuration, of various types of devices like CD drives, graphics and monitor, printer, scanner and so on. Actually, even for an experienced Novell linux sysadmin, you might well be inclined to use YaST whenever possible. A great time saver. Understand though that it won't help you when there are very specific and specialised tasks, where these might involve custom writing of scripts, for example. But the point about YaST is that it frees up your time to concentrate on those harder problems.
