Chapter 8. Maintenance

Important

SSL must be employed between the Satellite and its clients systems for this feature to work. If the

SSL 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 on

the 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

software channel for the Satellite within the central RHN website. Once installed, start the service on

the Satellite as root using the command:

service osa-dispatcher start

Finally, install the osad package on all client systems to receive pushed actions. The package can be

found within the RHN Tools child channel for the systems on the RHN Satellite.

Warning

Do not install the osad package on the Satellite server, as it will conflict with the osa-

dispatcher package installed on the Satellite.

Once installed, start the service on the client systems as root using the command:

service osad start

Like other services, osa-dispatcher and osad accept stop, restart, and status commands,

as well.

Keep in mind, this feature depends on the client system recognizing the fully qualified domain

name (FQDN) of the Satellite. This name and not the IP address of the server must be used when

configuring the Red Hat Update Agent. Refer to the RHN Client Configuration Guide for details.

Now when you schedule actions from the Satellite on any of the push-enabled systems, the task will

begin immediately rather than wait for the system to check in.
