This GoLang mini-project creates a binary file that sends packets with a counter on an UDP port and prints the output to the stdout.
I use this udp-client project to verify the correct working of my infrastructure.

If you use this project together with my udp-server project, you can check if your firewalls are functioning properly
The output from the udp-server is:
