Introduction; Document Conventions - Red Hat NETWORK ENTERPRISE - USER REFERENCE GUIDE 2.0 User Reference Manual

Welcome to the Red Hat Network Enterprise User Reference Guide 2.0.
The Red Hat Network Enterprise User Reference Guide will guide you through registering your sys-
tem for Red Hat Network and using its many features. Depending on which version of Red Hat Linux
you have installed, the Red Hat Network Registration Client and the Red Hat Update Agent might
be different than the ones described in this manual as new features are added. Once you use Red Hat
Network to update these applications, you can use the latest version of this manual.
All versions of
http://www.redhat.com/docs/manuals/RHNetwork/.
This version of the manual covers version 3.0.7 of the Red Hat Update Agent and version 2.7.21-
7.x.3 of the Red Hat Network Registration Client.
Warning
Systems running Red Hat Linux 6.2 through 7.3 and Red Hat Linux Advanced Server will need to
use the separate Red Hat Network Registration Client before starting the Red Hat Update Agent.
Refer to Chapter 7 for instructions. Systems running Red Hat Linux 8.0 can go directly to the Red
Hat Update Agent, which has registration functionality built in for the latest release. Refer to Chapter
2 for instructions.
For a technical overview of Red Hat Network, please refer to the whitepapers available at
http://www.redhat.com/docs/wp/.

1. Document Conventions

When you read this manual, you will see that certain words are represented in different fonts, type-
faces, sizes, and weights. This highlighting is systematic; different words are represented in the same
style to indicate their inclusion in a specific category. The types of words that are represented this way
include the following:
command
Linux commands (and other operating system commands, when used) are represented this way.
This style should indicate to you that you can type the word or phrase on the command line
and press [Enter] to invoke a command. Sometimes a command contains words that would be
displayed in a different style on their own (such as filenames). In these cases, they are considered
to be part of the command, so the entire phrase will be displayed as a command. For example:
Use the
cat testfile
working directory.
filename
Filenames, directory names, paths, and RPM package names are represented this way. This style
should indicate that a particular file or directory exists by that name on your Red Hat Linux
system. Examples:
The file in your home directory contains bash shell definitions and aliases for your own
.bashrc
use.
The
/etc/fstab
this manual are
command to view the contents of a file, named
