The Red Hat Network Alert Notification Tool, the round icon in the panel of your Red Hat 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:
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.
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.
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.
