socket.error: [Errno 102] Operation not supported on socket

Question

I'm using Python on Mac.

But the below code

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(('127.0.0.1', 443))
s.listen(2048)

encounters the problem

Traceback (most recent call last):
  File "attacker.py", line 5, in <module>
    s.listen(2048)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 102] Operation not supported on socket

How to resolve this issue?

Solution

You are using a udp socket, SOCK_DGRAM, and udp does not listen for connections, it receives each message on its own Use recvfrom to receive udp messages
