Figure 2.2. Package Updater Applet
The Package Updater Applet stays in the notification tray of the desktop panel and checks for new
updates periodically. The applet also allows you to perform a few package maintenance tasks from the
applet by clicking the notification icon and choosing from the following actions:
• Refresh — Check RHN or the Satellite for new updates
• View Updates — launches the Package Updater application so that you can see any available
updates in more detail and configure the updates to your specifications
• Apply Updates — Download and Install all updated packages.
• Quit — close the applet
2.4. Configuring the Red Hat Network Alert Notification Tool
with Satellite
The Red Hat Network Alert Notification Tool, the round icon in the panel of your Red Hat Enterprise
Linux 3 or 4 desktop, can be configured on systems running Red Hat Enterprise Linux 3 or later to
recognize updates available from custom channels on your RHN Satellite Server. You must ensure
the RHN Satellite Server is configured to support this feature. (RHN Proxy Server supports the
applet without modification of client or server.) The steps to configure the Red Hat Network Alert
Notification Tool are as follows:
1. Ensure that your RHN Satellite Server is version 3.4 or later and that you have the rhns-applet
package installed on the Satellite. The package can be found in the RHN Satellite software
channel for versions 3.4 and newer.
2. Retrieve the rhn-applet-actions package with up2date or through the Red Hat Network
Tools software channel. Install the package on all Red Hat Enterprise Linux 3 and newer client
systems to be notified of custom updates with the Red Hat Network Alert Notification Tool. The
client systems must be entitled to the Management or Provisioning service levels.
3. Within the Satellite's version of the RHN website, go to the System Details page for each system
and click the link within the RHN Applet area to redirect the Red Hat Network Alert Notification
Tool to the Satellite.
The next time the applet is started, it will apply its new configuration and connect to the RHN Satellite
Server for updates.
