Red Hat Network Overview
Have you ever read about a new version of a software package and wanted to install it but
could not find it?
Have you ever tried to find an RPM through an Internet search engine or an RPM repository
and been linked to an unknown site?
Have you ever tried to find an RPM but instead found only source files that you had to compile
yourself?
Have you ever spent hours or even days visiting different websites to see if you have the latest
packages installed on your system, only to have to do it again in a few months?
Those days are over with Red Hat Network (RHN). RHN provides the solution to all your system
software management needs.
Red Hat Network is an Internet solution for managing a single Red Hat Enterprise Linux system
or a network of Red Hat Enterprise Linux systems. All Security Alerts, Bug Fix Alerts, and
Enhancement Alerts (collectively known as Errata Alerts) can be downloaded directly from Red
Hat or your own custom collection. You can even schedule updates for delivery to your system
immediately after release.
The main components of Red Hat Network are as follows:
• the Red Hat Update Agent
• the Red Hat Network website, whether this is hosted by the central RHN Servers, an RHN
Satellite Server, or fed through an RHN Proxy Server
• Red Hat Network Daemon
• the Red Hat Network Registration Client - for systems running Red Hat Enterprise Linux
2.1 only.
The Red Hat Update Agent (
up2date
) provides your initial connection to Red Hat Network.
Red Hat Enterprise Linux 3 and newer systems use the Red Hat Update Agent to register with
RHN. Registration involves creating a unique RHN username and password, probing the
hardware on your system to create a Hardware Profile, and probing the software packages
installed on your system to create a Package Profile. This information is sent to RHN and RHN
returns a unique System ID to your system. Once registered, the Red Hat Update Agent
enables channel subscription, package installs, and management of System Profiles. See
Chapter 2, Red Hat Update Agent for further information.
The Red Hat Update Agent, as the base component of RHN, is designed to manage a single
system. It allows the system's superuser to view and apply Errata to the system. The RHN web
interface facilitates the management, monitoring, and provisioning of a large deployment of
systems, including the configuration of the Red Hat Update Agent for each system.
