Chapter 9 Push Notification Server 189
Starting and Stopping Push Notification
When you start push notification on a server, the service broadcasts its availability on
the local network to other services that support it. This means that when a different
server turns on a service that supports push notification, the push notification server
address populates the settings of the pushing service.
You must still enable Push Notification support for the pushing service before it works.
Additionally, you can choose to encrypt the data passed between the client and the
push server by choosing an SSL certificate. This does not encrypt the data between the
client and the pushing service. To encrypt transport between the pushing service and
the client, enable SSL with the pushing service.
To enable Push Notification:
1 Use Server Admin to connect to the server.
2 Enable administration of Push Notification.
This only needs to be done the first time you use Server Admin to administer the
server.
For more information about adding a service to the administered services list, see
“Adding and Removing Services in Server Admin” on page 146.
3 From the list of administered services for the desired server, select Push Notification.
4 Click the “Start Push Notification” or “Stop Push Notification” as needed.
From the command line:
# setting Server Admin administration of push notification
sudo serveradmin settings info:serviceConfig:services:com.apple.
ServerAdmin.Notification:configured = yes
# on the notification server
sudo serveradmin start notification
