RHN Management and Provisioning customers with the Activation Key Administrator role (including Organization Administrators) can generate activation keys through the RHN website. These keys can then be used to register a Red Hat Enterprise Linux system, entitle the system to an RHN service level and subscribe the system to specific channels and system groups through the command line utility rhnreg_ks. Refer to Section 2.5, “Registering with Activation Keys” for instructions on use.
