1. You don't need to attach to parents service, you can also call start/stopService directly. 2. You can still call "self.port = reactor.listenTCP(...)" directly in a custom startService, and self.port.stopListening() in a custom stopService. You don't have to use twisted.application.internet, it doesn't add much beyond a little convenience. The point of services is to encapsulate startup and shutdown logic, not to make your life harder :) _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
