Red Hat Network Alert Notification Tool
The Red Hat Network Alert Notification Tool is a notifier that appears on the panel
and alerts users when software package updates are available for their systems. The list
of updates is retrieved from the RHN Servers. The system does not have to be registered
with Red Hat Network to display a list of updates; however, retrieving the updates with the
Red Hat Update Agent requires registration with Red Hat Network and a subscription to
an RHN service offering. The notifier does not send any identifiable information about the
user or the system to the RHN Servers.
To use the
Red Hat Network Alert Notification Tool , you must install the
rhn-applet
RPM package and use the X Window System.
Starting with Red Hat Enterprise Linux 3, the
Red Hat Network Alert Notification Tool
appears on the panel by default as shown in Figure 4-1.

If it does not appear on the panel, you can add it:
•
In Red Hat Enterprise Linux 3 and later, select Applications (the main menu on the
panel) => System Tools => Red Hat Network Alert Icon . To ensure the icon appears
on subsequent sessions, select the Save current setup checkbox when logging out.
•
In Red Hat Enterprise Linux 2.1, select the Main Menu Button => Panel => Add to
Panel => Applet => Red Hat Network Monitor . To move it around the panel, right-
click on the applet, select Move , move the mouse left and right until it is in the desired
location, and click the mouse to place the applet.
4.1. Configuring the Applet
The first time the Red Hat Network Alert Notification Tool is run, a configuration wizard
starts. It displays the terms of service and allows the user to configure an HTTP proxy as
shown in Figure 4-2.
