Red Hat Network saves you time because you receive email when updated packages are released. You do not have to search the Web for updated packages or security alerts. By default, Red Hat Network installs the packages as well. You do not have to learn how to use RPM or worry about resolving software package dependencies; RHN does it all.

Red Hat Network features include:


You must activate your Red Hat Enterprise Linux product before registering your system with Red Hat Network to make sure your system is entitled to the correct services. To activate your product, go to:

After activating your product, register it with Red Hat Network to receive Errata Updates. The registration process gathers information about the system that is required to notify you of updates. For example, a list of packages installed on the system is compiled so you are only notified about updates that are relevant to your system.

The first time the system is booted, the Software Update Setup Assistant prompts you to register. If you did not register then, select Applications (the main menu on the panel) => System Tools => Package Updater on your desktop to start the registration process. Alternately, execute the command yum update from a shell prompt.
