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):
File "C:\Python26\lib\SocketServer.py", line 281, in
_handle_request_noblock
self.process_request(request, client_address)
File "C:\Python26\lib\SocketServer.py", line 307, in process_request
self.finish_request(request, client_address)
File "C:\Python26\lib\SocketServer.py", line 320, in finish_request
self.RequestHandlerClass(request, client_address, self)
TypeError: 'NoneType' object is not callable
----------------------------------------
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
Sincerely,
Me
