ServiceControlClients 
IP addresses or names of clients that can send service control actions to the service. To type multiple addresses, separate the individual addresses with commas (there must be no space before or after the comma).
Alternatively, you can use wildcards in the IP address. Type for example 187.*.*.* to permit any machine whose IP address begins with 187 to control the connector.
