twisted.internet.udp.Port.startListening
Create and bind my socket, and begin listening on it.
This is called on unserialization, and must be called after creating a server to begin listening on the specified port.
Called when a connection fails. Stop listening on the socket.
Parameters | reason | Why the connection failed. (type: Failure ) |
Get the remote address of this connection.
Treat this method with caution. It is the unfortunate result of the CGI and Jabber standards, but should not be considered reliable for the usual host of reasons; port forwarding, proxying, firewalls, IP masquerading, etc.
Returns | An IAddress provider. |
