Hi Christian! Thanks for the quick help and netcat tip. I was able to send from my script and receive with netcat (for example: *nc -u -6 -l 8000*) without any problems. (sending to port 8000 in my script)
I've tried doing the reverse situation, where I receive on the script side and send using netcat, but I haven't been able to get this to work. I don't have any errors, but I'm not receiving anything for some reason. I'll work on some chicken scripts that talk to each other and see if I can get this to work properly. Thanks again for your help!
