Hi,
I'm trying to implement an IWriteDescriptor using raw sockets. So far this is what I wrote... but it doesn't work: https://github.com/david415/hushTCP/blob/master/hush_writer.py
Am I doing something obviously wrong here?
I certainly am able to use raw socket + scapy correctly without Twisted.
Please describe the problem in more detail than "it doesn't work". >:) Your hush_writer.py is a good <http://sscce.org/> but it's still important to know how its behavior differs from your expectations. As far as I can tell it does work - although there's one mistake that makes it a bit more inefficient than strictly necessary: def doWrite(self): if len(self.packets) > 0: self.socket.sendto(self.packets.pop(0), self.address) else: return When you're out of packets you should remove the writer from the reactor. This version of the code will perpetually dispatch writeable notification (in the form of a doWrite call) to your object as fast as possible. Once you fix this, don't forget to re-add the writer as soon as len(self.packets) rises above 0 again. Jean-Paul
