To be used when you send data to another host. On the other host, to avoid ICMP traffic about the port not being open, do: ./nc -l -u -p 9999 > /dev/null You need to restart this command each time you run macpdu2wireshark. You can use any other program that will accept UDP packets on the port 9999 (default port of macpdu2wireshark, change if you use another port of course).
