I;m trying to impleting hostname resolution in a program that aimed to exchange UDP packets with his peers.

What I do is add the two lines: dd = reactor.resolve(IP) dd.addCallback(self.call, distPort, password, destroy)

To my program, but when I do that, I don't reach the call function. Seems like something would be missing. Does anyone have a clue?

Yes, we do.

What is missing is the rest of your program; that is, the parts that contain the bug.

You owe the Oracle a bottle of crystal ball polish[1].

[2] Yes, the grovel _was_ insufficient.

Hi Jp, thanks for your answer but what do you mean byt the "wrong" thread? this one is the one where all my reactor things are.

Sorry, here is a more complete listing of the part that could help:

The program calls functions from the wrong thread. Almost every single Twisted API may only be invoked from the reactor thread.

Why are you using threads at all? Most programs don't need them.
