Create fake UDP traffic

Question

I have to write a UDP client. Unfortunately, the source system is not always available

Is there a simple tool out there that I can use to create a fake UDP server/traffic on my machine?

Answer 1

You could use netcat with the -u option to send data over UDP.

Answer 2

Why don't you create UDP socket and fill it with dummy data?

PS: What do you mean by source system? Do you mean sender? In that case, you can generate localhost UDP socket.
