About This Guide
This guide is intended for use by professional network and system administrators during
the actual planning, deployment, conguration, and operation of SUSE Linux Enter-
prise®. As such, it is solely concerned with ensuring that SUSE Linux Enterprise is
properly congured and that the required services on the network are available to allow
it to function properly as initially installed. This guide does not cover the process of
ensuring that SUSE Linux Enterprise offers proper compatibility with your enterprise's
application software or that its core functionality meets those requirements. It assumes
that a full requirements audit has been done and the installation has been requested or
that a test installation, for the purpose of such an audit, has been requested.
This guide contains the following:
Deployment
Before you install SUSE Linux Enterprise, choose the deployment strategy and
disk setup that is best suited for your scenario. Learn how to install your system
manually, how to use network installation setups, and how to perform an autoinstal-
lation. Congure the installed system with YaST to adapt it to your requirements.
Administration
SUSE Linux Enterprise offers a wide range of tools to customize various aspects
of the system. This part introduces a few of them.
System
Learn more about the underlying operating system by studying this part. SUSE
Linux Enterprise supports a number of hardware architectures and you can use this
to adapt your own applications to run on SUSE Linux Enterprise. The boot loader
and boot procedure information assists you in understanding how your Linux system
works and how your own custom scripts and applications may blend in with it.
Services
SUSE Linux Enterprise is designed to be a network operating system. It offers a
wide range of network services, such as DNS, DHCP, Web, proxy, and authentica-
tion services, and integrates well into heterogeneous environments including MS
Windows clients and servers.

Security
This edition of SUSE Linux Enterprise includes several security-related features.
It ships with Novell® AppArmor, which enables you to protect your applications
by restricting privileges. Secure login, rewalling, and le system encryption are
covered as well.
Troubleshooting
SUSE Linux Enterprise includes a wealth of applications, tools, and documentation
should you need them in case of trouble. Some of the most common problems that
can occur with SUSE Linux Enterprise and their solutions are discussed in detail.
