Enabling Push to ClientsIn addition to allowing client systems to regularly poll the Satellite for scheduled actions, you mayenable the Satellite to immediately initiate those tasks on Provisioning-entitled systems. This bypassesthe typical delay between scheduling an action and the client system checking in with RHN to retrieveit.ImportantSSL must be employed between the Satellite and its clients systems for this feature to work. If theSSL certificates are not available, the daemon on the client system fails to connect.To take advantage of this feature, you must first configure your firewall rules to allow connections onthe required port(s), as described in Section 2.4 Additional Requirements.Then you must install the osa-dispatcher package, which can be found in the RHN Satellite Serversoftware channel for the Satellite within the central RHN website. Once installed, start the service onthe Satellite as root using the command:service osa-dispatcher startFinally, install the osad package on all client systems to receive pushed actions. The package canbe found within the RHN Tools child channel for the systems on the RHN Satellite Server.

This name and not the IP address of the server must be used when configuringthe Red Hat Update Agent.
