Hello,

I have some digital signage software that can send out a network message (0x02PON0x03) to switch on a TV. I want to be able to control the display without the signage software.

I have tried using netcat to no avail. Is there a method I can use wireshark to monitor and analyze the message sent form the signage software so I can duplicate it?

Any help will be gratefully received.

Cheers dan

Sure, you need to find a way to capture the packet containing the message when it is sent from the original software. This can be done by using a switch with a SPAN port feature or with a hub if you have one. Connect TV and the system with the original software to it, and (if you're not using a hub) configure the switch to copy the data of the software to another port where you connect a PC running Wireshark. Capture wile the software sends the code.
