　　843端口的服务代码为： from twisted.internet import reactor from twisted.internet.protocol import Factory, Protocol class PolicySocketProtocol(Protocol): def dataReceived(self, data): self.transport.write("\0") class PolicyFactory(Factory): def __init__(self): self.protocol = PolicySocketProtocol; if __name__ == '__main__': reactor.listenTCP(843, PolicyFactory(), interface="127.0.0.1") reactor.run()
