Solve : Sniffing Set top boxes?

1.	Solve : Sniffing Set top boxes?
Answer» Hi all, I'am trying to SNIFF the traffic of set top box which is connected to local 5 port netgear switch, all i can see is udp streams and ssdp requests and that too from different ip address which is not reachable if i try to ping / nmap also Set top box ip address is like 192.168.x.x and from that i can only see ssdp requests and none other evident traffic like authentication/any other port -ip connection /protocols etc so the question arises here is , am i doing it right ? or i need to do something like port forwarding or port mirroring ? i won't be able to do such thing i think because the switch DOESNT have any such interface of changing configurations i guess. any suggestions or advice will be very helpful.

Therefore you would need something like port mirroring however this of course requires a switch that supports it. A couple of cheaper options would be to connect the STB directly into your PC and use it to provide an internet connection to the box such as through Windows's internet connection sharing. You could also pick up a cheap, used hub as this will blindly forward packets to all ports allowing you to sniff them (much like you get with a switch with port mirroring).thanks cameron, that was quite informative from you, so now another question is .. can i setup a server which STB communicates directly to on my MACHINE? if yes does anyone has such information on kind of server that has to be setup?

Hi all,

I'am trying to SNIFF the traffic of set top box which is connected to local 5 port netgear switch,
all i can see is udp streams and ssdp requests and that too from different ip address which is not reachable if i try to ping / nmap
also Set top box ip address is like 192.168.x.x and from that i can only see ssdp requests and none other evident traffic like
authentication/any other port -ip connection /protocols etc
so the question arises here is , am i doing it right ? or i need to do something like port forwarding or port mirroring ?
i won't be able to do such thing i think because the switch DOESNT have any such interface of changing configurations i guess.
any suggestions or advice will be very helpful.

THANKS !Why do you want to do that?
