I suspect the 10/100 wired network is based around an ethernet switch which means you will only see traffic directed to your address (on the unit running ethereal) or broadcast traffic and therefore may not see routed traffic between the plays.  To watch all the traffic going to the cable modem, plug a 10 mbps HUB between the cable modem and the 10/100 wired network and then plug the ethereal unit into the HUB.  This will let you see every packet that goes to or from the cable modem,

Subject: [Ethereal-users] XBOX live packet analyzer?

 we installed xbox live and I'm trying to use ethereal capture and analyze the network traffic.

 

so far what I'm seeing doesn't seem to account for the amount of activity on the xbox.  for those of you not familiar with xbox live, the player is on-line with one or more other players, interacting in the common virtual space of the game.   the players continuously talk with the voice headset.    the voice quality is very decent, and low latency.

what I see on ethereal is intermittent traffic typical of home network, but I expect to see more traffic related to xbox live voice.  It might be a simple matter of reconfiguring the network - see comments below.

 

I'm curious if anyone out there has attempted this, or can shed some light on how the xbox live network operates.

 

 

 

My home network looks like this:

 

 

 

                                                                                                                    cable

                                                                                                                    modem

                                                                                                                       ^

                                                                                                                       |

and                                                                                                            windows

the "tap point" for ethereal is my laptop on the wired 10/100 network.  Since every packet must pass through the cable modem, I believe this configuration should let me capture packets for xbox.  but perhaps the cable modem should be hooked up through a separate 10/100 switch.
