Chapter 8. Maintenance 69
Please note that changing the password on the RHN website changes only the local pass-
word on the RHN Satellite Server, which may not be used at all if PAM is enabled for that
user. In the above example, for instance, the Kerberos password will not be changed.
8.10. Enabling Push to Clients
In addition to allowing client systems to regularly poll the Satellite for scheduled actions,
you may enable the Satellite to immediately initiate those tasks on Provisioning-entitled
systems. This bypasses the typical delay between scheduling an action and the client sys-
tem checking in with RHN to retrieve it.
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 Server 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 pack-
age can be found within the RHN Tools child channel for the systems on the RHN Satellite
Server. 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.
