Python send UDP packet

Question

I am trying to write a program to send UDP packets, as in https://wiki.python.org/moin/UdpCommunication The code appears to be in Python 2:

import socket

UDP_I         


        

Answer 1

Your code works as is for me. I'm verifying this by using netcat on Linux.

Using netcat, I can do nc -ul 127.0.0.1 5005 which will listen for packets at:

• IP: 127.0.0.1
• Port: 5005
• Protocol: UDP

That being said, here's the output that I see when I run your script, while having netcat running.

[9:34am][wlynch@watermelon ~] nc -ul 127.0.0.1 5005
Hello, World!
