echo -n “foo” | nc -4u -w1 <host> <udp port>
#Here’s quick breakdown of what’s happening:

#-n - Tells the echo command to not output the trailing newline.
#-4u Use IPV4 addresses only.  Use UDP instead of TCP.
#-w1 Silently close the session after 1 second of idle time.  That way, we’re not stuck waiting for more data.
