Introduction

This document discusses issues surrounding the deployment and maintenance of customized

software channels for RHN Proxy Server and RHN Satellite Server. It is used after the RHN

Satellite Server or RHN Proxy Server is installed and configured.

In some instances, this document refers to actions that are performed on the Red Hat Network

Web servers. For RHN Proxy Server customers, this refers to the central Red Hat Network

Servers at https://rhn.redhat.com. For Satellite customers, this refers to the RHN Satellite

Server at your site.

Chapter 1.

Introduction to RHN Channels

A Red Hat Network channel is a collection of software packages. Channels help you segregate

packages by sensible rules: a channel may contain packages from a specific Red Hat

distribution, for instance. A channel may contain packages for an application or family of

applications. Users may also define channels for their own particular needs; a company may

create a channel that contains packages for all of the organization's laptops, for example.

1. Base Channels and Child Channels

There are two types of channels: base channels and child channels. A base channel consists of

packages based on a specific architecture and Red Hat Enterprise Linux release. A child

channel is a channel associated with a base channel that contains extra packages.

A system must be subscribed to only one base channel. A system can be subscribed to multiple

child channels of its base channel. A subscribed system can only install or update packages

available through its Red Hat Network channels.

When a system is registered with Red Hat Network, it is assigned to the base channel that

corresponds to the system's version of Red Hat Enterprise Linux. Once a system is registered,

its default base channel may be changed to a private base channel on a per-system basis via

the RHN website. Alternately, you can have activation keys associated with a custom channel

so that systems registering with those keys are automatically associated with the custom

channel.

On the Red Hat Network website, the Channels page (located under the Channels tab on the

top navigation bar) provides a list of all base channels and their child channels. Clicking on the

name of a channel displays the Channel Details page, which provides a list of all of the

packages in that channel, its errata, and any associated systems.

2. Subscribing to Channels

Subscribe systems to channels in the following ways:

• Registration through activation keys — Because of the simplicity and speed of activation

keys, this is the preferred method for registering systems as clients of either RHN Proxy

Server or RHN Satellite Server. Systems registered using an activation key are subscribed to

all channels associated with that activation key. For more information on activation keys,

consult the Red Hat Network Client Configuration Guide and the Red Hat Network Reference

Guide.

• Install registration — When a system is initially registered through either the Red Hat Update

Agent or the Red Hat Network Registration Client, it is automatically assigned to the base

channel that corresponds to the version of Red Hat Enterprise Linux on the system. Once a

system is registered, its default base channel may be changed to a private base channel on a

per-system basis via the RHN website. Alternately, you can have activation keys associated

Chapter 2.

with a custom channel so that systems registering with those keys are automatically

associated with the custom channel. For more information on using these applications, refer

to the respective chapter of the RHN Reference Guide for your entitlement level

(Management or Provisioning).

• Website subscription — Various specific child channels are available for subscription,

depending on the system's base channel. The system may be subscribed to the child channel

through the RHN website. If you have created your own base channels, you may also

reassign systems to these custom channels through the website. For more information on

subscribing to channels online, refer to the Red Hat Network Website chapter of the RHN

Reference Guide.

3. Channel Availability

There are many channels in Red Hat Network. Some are available to all users, some are

available to users in a particular organization, and some are available only if you have

purchased access to them. Channels fall into these main categories:

• Paid Service Channels — These channels are available if you who have purchased access to

them either directly or in conjunction with a particular Red Hat solution. Red Hat Enterprise

Linux is an example of a paid service channel.

• Custom Channels — You create these channels to manage custom packages. These

channels, also known as private channels, appear only to the organization who creates them;

they can never be accessed by anyone else.

This document focuses on the process of creating and maintaining custom channels with an

RHN Proxy Server or on an RHN Satellite Server.

4. Tools, Repositories, and Practices

Before creating and managing channels, note the differences between the various tools and

repositories at your disposal. This is especially important if you are deploying both an RHN

Satellite Server and RHN Proxy Server, as this increases the utilities and storage locations

available. Further, a Proxy-Satellite combination offers certain best practices for optimal

performance.

First, become familiar with these package management tools:

•RHN Package Manager - Use this to push custom packages into custom channels on your

RHN Proxy Server.

•RHN Push - Use this to push custom packages into custom channels on your RHN Satellite

Server.
