Ok, a networking and a Linux question.<br>
<br>
First, does anyone have a reference (URL or source code) that shows how<br>
to receive UDP broadcast packets from multiple sending devices? In<br>
other words, if I have two net devices each broadcasting UDP packets, I<br>
want to build a listener that will capture the packets from both devices<br>
(or more as I add devices).<br>
<br>
The Linux half of the question: is there a quick CLI way of playing<br>
with UDP similar to utilities like tcpconnect? I want to be able to<br>
examine the payloads before I dive into writing a C program although<br>
maybe writing the C program that just echos the payload is the way to go<br>
to figure out the base network stack.<br>
