Chapter 2. Requirements
Hat strongly recommends this information be copied onto two separate floppy disks, printed
out on paper, and stored in a fireproof safe.
In addition to these requirements, it is recommended that the RHN Satellite Server be
configured in the following manner:
• The entire RHN Satellite Server solution should be protected by a firewall if the Satellite
accesses or is accessed via the Internet. An Internet connection is not required for RHN
Satellite Servers running in completely disconnected environments. This feature instead uses
Channel Content ISOs that can be downloaded to a separate system to synchronize the
Satellite with the central Red Hat Network Servers. All other RHN Satellite Servers should be
synchronized directly over the Internet.
• All unnecessary ports should be firewalled off. Client systems connect to RHN Satellite Server
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
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
•
The 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, "Sendmail
Finally, you should have the following technical documents in hand for use in roughly this order:
1. The RHN Satellite Server Installation Guide — This guide, which you are now reading,
provides the essential steps necessary to get an RHN Satellite Server 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 Server. (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.
