System Administration Guide: Basic Administration

About This Book

System Administration Guide: Basic Administration is part of a set that includes a significant part of the Solaris^TM system administration information. This guide contains information for both SPARC^TM based and IA based systems.

This book assumes you have

Installed the SunOS^TM 5.9 operating system
Set up all the networking software that you plan to use

The SunOS 5.9 operating system is part of the Solaris product family, which also includes many features, including the Solaris Common Desktop Environment (CDE). The SunOS 5.9 operating system is compliant with AT&T's System V, Release 4 operating system.

For the Solaris 9 release, new features interesting to system administrators are covered in sections called What's New in ... ? in the appropriate chapters.

Note –

The Solaris operating environment runs on two types of hardware, or platforms, SPARC and IA. The Solaris operating environment runs on both 64–bit and 32–bit address spaces. The information in this document pertains to both platforms and address spaces unless called out in a special chapter, section, note, bullet, figure, table, example, or code example.

Who Should Use This Book

This book is intended for anyone responsible for administering one or more systems running the Solaris 9 release. To use this book, you should have 1-2 years of UNIX® system administration experience. Attending UNIX system administration training courses might be helpful.

General Conventions

Be aware of the following conventions used in this book.

When following steps or using examples, be sure to type double-quotes ("), left single-quotes (`), and right single-quotes (') exactly as shown.
The key referred to as Return is labeled Enter on some keyboards.
The root path usually includes the /sbin, /usr/sbin, /usr/bin, and /etc directories, so the steps in this book show the commands in these directories without absolute path names. Steps that use commands in other, less common, directories show the absolute paths in the examples.
The examples in this book are for a basic SunOS software installation without the Binary Compatibility Package installed and without /usr/ucb in the path.

Caution –
If /usr/ucb is included in a search path, it should always be at the end of the search path. Commands like ps or df are duplicated in /usr/ucb with different formats and options from the SunOS commands.
