How to send a single UDP packet with Netcat
At work today I needed this command to test UDP traffic to a particular endpoint, and thought I'd leave it written down here!
netcat command sends a single UDP packet with the string "foo" to a particular IPv4 address on a particular UDP port:
$ echo -n “foo” | netcat -u -w1 <host_ip> <port>
