12 Chapter 1:What is Red Hat Network?
The
Red Hat Network Daemon
(
rhnsd
) runs in the background as a service and probes the Red Hat
Network for notifications and updates at set time intervals (see Chapter 6, Red Hat Network Daemon
for further information).
1.1 Software Manager
Red Hat Network is the core infrastructure — the environment around which all the services are cen-
tered. The first subscription service offered through Red Hat Network is Software Manager. Addi-
tional service offerings will be available in the near future. Registering a system with Red Hat Network
is free as well as one subscription to Software Manager. With each Software Manager subscription,
you receive
• Errata Alerts — learn when Security Alerts, Bug Fix Alerts, and Enhancement Alerts are issued
for all the systems in your network
• Automatic email notifications — receive an email notification when an Errata Alert is issued for
your system
• RPM Updates — automatic delivery of packages with optional automatic installation
•
Red Hat Update Agent
— use the
Red Hat Update Agent
to download the lastest software
packages for your system with optional installation of packages
• Download List — use the Software Manager Web interface to create a download list of packages
from all the systems in your network and download all the packages at one time
For information on purchasing Software Manager subscription, refer to http://www.redhat.com/net-
work/purchase/.
1.2 Automatic Notifications
During registration, you can configure Red Hat Network to send you email notifications of new and
updated software packages. Automated notifications of the latest updates
• Reduce the time and effort required by system administrators to stay on top of the Red Hat errata
list
• Minimize security vulnerabilities in your network by providing the patches as soon as Red Hat
releases them
• Filter out package updates not relevant to your network
• Provide a reliable method of managing multiple systems with similar configurations
