Red Hat Knowledgebase

Once your system is registered on Red Hat Network (RHN), a small icon will appear on your tool bar (Red Hat Linux 7.3 and higher). The icon will display either an exclamation point with red background (meaning that there is an update waiting to be downloaded) or a check mark with blue background (meaning that there are no updates waiting). If your icon portrays a question mark, it means that Red Hat Network is not able to see your system.

By double clicking on the icon, this will activate Red Hat Network update tool.
