Thanks
it is not definitely on that port
netstat -lu | grep 19523 doers nothing

@DOkuwa, did you want to test on a port that is listening on udp, or are we ready to close the thread?

netstat -lu | grep 19523 is producing nothing
I think it is a TCP port

Yes, but your thread is about checking UDP. Can you clarify what your ultimate goal is? You already have a check_tcp command earlier in the thread that works.
