How to send a UDP packet with UDP length as 0 and no data












0















I am trying to reproduce a problem which is happening in live network.
I network whenever a packet with UDP length 0 is coming my network equipment is crashing.
So to reproduce the same scenario in my LAB i need to send a UDP packet with UDP length 0 and no data block.



How can i go about it?

    Use a raw ip socket.

You didn't say which language you want to use but your profile shows some Python activity, so here's how to do it in Python:



import socket
import time

dest_addr = '10.9.87.64' # the destination address or hostname
dest_port = 1234 # the destination port

usock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, 0)

while True:
usock.sendto('', (dest_addr, dest_port))
time.sleep(10)


That creates a UDP endpoint named usock and then loops forever, sending an empty string (which produces a datagram with a zero-length payload) through that endpoint to the specified destination and then waiting for ten seconds before repeating.
