Hi,

If you capture the network traffic you can click on a packet from the multimedia device and look at the protocol details dissected by Wireshark.

Thanks,
Jaap

Hi,

I think Wireshark can help you here. Start a capture on the network
interface the multimedia device is connected to, and trigger it into
communicating with the server. You can apply a display filter to focus on
their communication, by means of ip address of the multimedia device
(ip.addr == <IP address multimedia device>), or on TCP port number
(tcp.port == <port number>) or UDP port number (udp.port == <port number>),
whatever protocol is applicable, of the server process.


Thank you Jaap. I don't know the protocol or port numbers that are
actually being used. If I filter on IP address (which I do know) how
do I see the port number?
