At this page
--> http://twistedmatrix.com/documents/current/howto/udp
is an example that shows how connected UDP is done
with Twisted. I can't get it to work.
When I run it, it says:
....
self.startProtocol()
File "./client2.py", line 10, in startProtocol
d.addCallback(self._cbConnected)
AttributeError: 'NoneType' object has no attribute 'addCallback'
....
I.e it looks like the
"d = self.transport.connect("ip_to_listening_server", listen_port_nbr)"
doesn't return anything?
As server at "the other side" I've used the first example
and I have also tried using netcat as an listening UDP-server.
I'm sure that the IP-adress and port is correct in my code,
so it can't be that.
(Btw, the self.transport.write .. line is not correct indented
I suppose?)
Anyone that can help me with this?
