#OpenServiceOnNonDialUpInterfaces(service, fallback_ports) ⇒ Object

Function opens up the service on all non-dial-up network interfaces. If there are no network interfaces known and the 'any' feature is supported, function opens the service for the zone supporting that feature. If there are only dial-up interfaces, function opens the service for them.

Parameters:

  • service (String) —

    such as "service:koo" or "serice:boo"

  • fallback_ports (Array<String>) —

    list of ports used as a fallback if the given service doesn't exist
