Additional Requirements

Note

If you are running a disconnected Satellite that is not registered to RHN Hosted the installation

program will note and return a list of any missing additional packages needed beyond @base

to be installed, then the installation program will exit. This allows you to install those packages.

You may want to use the installation ISO image or DVD media to create a repository for those

additional packages, and then rerun the Satellite installer.

• All unnecessary ports should be firewalled off. Client systems connect to RHN Satellite over ports

80, 443, and 4545 (if Monitoring is enabled). In addition, if you plan to enable the pushing of actions

from the Satellite to client systems, as described in Section 8.11, “Enabling Push to Clients”, you

must allow inbound connections on port 5222. Finally, if the Satellite will also push to an RHN Proxy

Server, you must also allow inbound connections on port 5269.

• No system components should be directly, publicly available. No user other than the system

administrators should have shell access to these machines.

•

All unnecessary services should be disabled using ntsysv or chkconfig.

•

The httpd service should be enabled.

•

If the Satellite serves Monitoring-entitled systems and you wish to acknowledge via email the

alert notifications you receive, you must configure sendmail to properly handle incoming mail as

described in Section 4.5, “Sendmail Configuration”.

Finally, you should have the following technical documents in hand for use in roughly this order:

1. The RHN Satellite Installation Guide — This guide, which you are now reading, provides the

essential steps necessary to get an RHN Satellite up and running.

2. The RHN Client Configuration Guide — This guide explains how to configure the systems to be

served by an RHN Proxy Server or RHN Satellite. (This will also likely require referencing The

RHN Reference Guide, which contains steps for registering and updating systems.)

3. The RHN Channel Management Guide — This guide identifies in great detail the recommended

methods for building custom packages, creating custom channels, and managing private Errata.

4. The RHN Reference Guide — This guide describes how to create RHN accounts, register and

update systems, and use the RHN website to its utmost potential. This guide will probably come in

handy throughout the installation and configuration process.
