[Twisted-Python] How to create a new service and listen on a new port?

[Eric Hsu]

Now I've figured out the solution!
Just remove the "reactor.run()" as Jp suggestion!

Here is the sample code which fulfills my requirements:

class AClass(DatagramProtocol):
    def datagramReceived(self, data, addr):
        # do something...
        anotherService1 = reactor.listenUDP(port1, AnotherService())
        anotherService2 = reactor.listenUDP(port2, AnotherService())
        # ...
        anotherServiceN = reactor.listenUDP(portN, AnotherService())

        # if we want to stop one of the AnotherServiceS, just
        anotherServiceX.stopListening()
        
class AnotherService(DatagramProtocol):
     def datagramReceived(self, data, addr):
        # blah blah blah...

Thank you all guys!
