Dear Tutors,
I have attached my 2 programs for networking. It uses socket and
SocketServer, but it just simplifies it even more. The problem is it won't
work. The Client raises the error, (with trace back)
Traceback (most recent call last):
File "G:\My Dropbox\My Dropbox\Chris\Not done\client.py", line 34, in<module>
print client.recv()
File "G:\My Dropbox\My Dropbox\Chris\Not done\client.py", line 16, in recv
return self.__sock.recv(1024)
error: [Errno 10053] An established connection was aborted by the software in
your host machine
The server seems to get an error of some sort, but also seems to catch and
print it. It prints
----------------------------------------
Exception happened during processing of request from ('127.0.0.1', 1424)
Traceback (most recent call last):

I look at both of the documentations of socket and SocketServer, but I couldn't
firgue it out. I don't know much about networking. Please Help
I don't know much about networking, less so about it on Windows; also, I've
only scanned quickly through the server script, but I notice your
create_handler() function doesn't return anything. I guess it needs to return
the Handler class.
The example in the Python docs doesn't use a factory function, but instead
directly puts the class as the second argument to TCPServer.
So the second argument needs to be a class, but since your create_handler()
function returns nothing, you presumably get this NoneType exception.

Yeah, that could be a problem. It should return the class.
