I thought this would be easy enough but for some reason I am unable to do this.

my sonos ip is: for example

Is there a way I can monitor for any requests from computers on the LAN to the sonos controller? I have set a live capture running and used my mobile to browse sonos controller and search for music etc but there is no indication that my phone ip has talked to the sonos controller.

Anyone have any tips on how to achieve this, it seems to be a logical thing someone might want to do on a large network to check who's mucking around with the sonos controller.

You might want to read the Wireshark Wiki page on capturing packets. As it is not as straightforward as just starting Wireshark.

Switches for instance have tables that map mac-addresses to ports so it can send traffic to only those ports that need to receive the traffic. In your case, traffic from your mobile to the Sonos system will only be sent to the Sonos system, not your Wireshark laptop, unless you take special measures.

And Wireless has it's own difficulties in getting a proper capture file.

I realised that if I capture traffic from my LAN computer and attempt to connect to the sonos, wireshark does show packets between my computer and the sonos controller.

The mobile phone is on Wifi but connected to the same LAN (I can ping it from my pc) But I can't seem to capture any http traffic at all?

Sorry I am new to wireshark.

Seems that I would need a wireless card to do that

We all started new, no worries :-)

What would help in helping you is to know how your Sonos is connected. Do you have any switches or routers. Basically a network description (make sure you include if a connection is wired or wireless and what kind of devices are involved).

My guess is that your Phone and your Sonos are both on WiFi, which means they communicate over your WiFi accesspoint. However, traffic will not leave the AP on the wired network, so the only way to capture the traffic is to pull it from the air.

See the Wiki page on WLAN capture for more info on capturing WiFi traffic. Note that it isn't an easy task, particularly on Windows due to Wifi adaptor driver\firmware issues.

My Sonos is connected via an ethernet cable. I have realised that because everything goes back to an unmanaged switch then I can't do any port mirroring so I am unable to monitor all traffic on the network. I can only monitor traffic from the device I am physically running wireshark on. Wish that Sonos could simply add an admin page that shows connected devices, that would solve the problem.
