The Red Hat Network Daemon must be enabled onthe systems for this feature to work.4.4.5. System EntitlementsTo use all of the features of RHN, your systems must be entitled — subscribed to an RHN servicelevel. Use the System Entitlements page to configure which systems are entitled to which serviceofferings. There are three primary types of entitlements:• Update — should be used to manage a single Red Hat Linux system. It includes Errata Alerts,Scheduled Errata Updates, Package Installation, and the Red Hat Update Agent.• Management — should be used to manage multiple systems with multiple system administrators.In addition to the features of the Update offering, it includes system group management, user man-agement, and the System Set Manager interface to quickly perform actions on multiple systems.• Provisioning — offers the highest level of functionality. It should be used to provision multiple sys-tems that will need to be re-installed and reconfigured regularly. The Provisioning offering providestools for kickstarting machines, managing their configuration files, conducting snapshot rollbacks,and inputting searchable custom system information, as well as all of the functionality included inthe Management service level.The System Entitlements page allows you to view and promote the entitlements for your registeredsystems. Only increases in entitlement levels are allowed. Systems cannot be re-entitled to a lowerentitlement level. For instance, a system entitled to the Update service level can be promoted to theManagement level, but this action cannot be reversed.To change an individual entitlement, select the entitlement from the system’s pulldown menu andclick the Update Entitlements button on the bottom right-hand corner of the page. Click the name ofa system to see details about it. If no drop-down menu exists for your Update-level system, you mayneed to purchase a Management entitlement. Do this through the Buy Now page under Your RHN.
