System Administration Guide: Advanced Administration

About This Book

System Administration Guide: Advanced Administration is part of a set that covers a significant part of the Solaris^TM system administration information. This guide includes information for both SPARC® and x86 based systems.

This book assumes that you have installed the SunOS^TM Solaris Operating System. It also assumes that you have set up any networking software that you plan to use. The SunOS Solaris Operating System is part of the Solaris product family, which also includes many features, including the GNOME Desktop Environment. The SunOS Solaris Operating System is compliant with AT&T's System V, Release 4 operating system.

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

Note –

This Solaris release supports systems that use the SPARC and x86 families of processor architectures: UltraSPARC®, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems appear in the Solaris 10 Hardware Compatibility List at http://www.sun.com/bigadmin/hcl. This document cites any implementation differences between the platform types.

In this document these x86 related terms mean the following:

“x86” refers to the larger family of 64-bit and 32-bit x86 compatible products.
“x64” points out specific 64-bit information about AMD64 or EM64T systems.
“32-bit x86” points out specific 32-bit information about x86 based systems.

For supported systems, see the Solaris 10 Hardware Compatibility List.

Who Should Use This Book

This book is intended for anyone responsible for administering one or more systems that are running the Solaris 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.

Typographic Conventions

The following table describes the typographic conventions that are used in this book.

Table P–1 Typographic Conventions


Typeface	Meaning	Example
`AaBbCc123`	The names of commands, files, and directories, and onscreen computer output	Edit your `.login` file. Use `ls -a` to list all files. `machine_name% you have mail.`
`AaBbCc123`	What you type, contrasted with onscreen computer output	`machine_name%` `su` `Password:`
`aabbcc123`	Placeholder: replace with a real name or value	The command to remove a file is `rm` `filename`.
AaBbCc123	Book titles, new terms, and terms to be emphasized	Read Chapter 6 in the User's Guide. A cache is a copy that is stored locally. Do not save the file. Note: Some emphasized items appear bold online.

Shell Prompts in Command Examples

The following table shows the default UNIX system prompt and superuser prompt for the C shell, Bourne shell, and Korn shell.

Table P–2 Shell Prompts


Shell	Prompt
C shell	`machine_name%`
C shell for superuser	`machine_name#`
Bourne shell and Korn shell	`$`
Bourne shell and Korn shell for superuser	`#`

General Conventions

Be aware of the following conventions that are 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.
It is assumed that the root path 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 path in the example.
The examples in this book are for a basic SunOS Solaris 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 different options from the SunOS Solaris commands.
