Iwant to sniff traffic going through my wireless router. The router is provided by my cable company, so I don't want to flash the firmware or anything, so my questions is: Is there any software or such that I can install on one of the computers on my network, and have it log the HTTP request/response?
Note: I've already tried setting up a proxy and logging that way. The game seems to be bypassing my Proxy settings. Other web traffic will go through my proxy, but not the game's traffic. I know it's using HTTP, because the game DOES obey the proxy on my friend's iphone (same game). So setting up a proxy isn't a solution that will work.
Another approach is to try using ettercap to sniff your LAN. It has various man-in-the-middle techniques - the most useful on a LAN is the poison ARP Man-In-The-Middle (MITM) approach (assuming your default gateway is 192.168.0.1 - check in your network settings):
Otherwise you'll need to investigate your router and check if it can support port mirroring or link layer bridge modes. The Thomson/Technicolor/Speedtouch routers do support PPP over Ethernet (PPPoE) bridging and some can also do port mirroring.
cheapest fix - use your cable router as a modem, then buy a router that supports mirroring to broadcast your wifi. (*shut off wifi on the cable modem and hard wire the new router to it for internet - that way all wireless traffic gets captured.) You can then pick any connected device as the target of your mirror - pick one with decent storage and remember it can only capture when connected to your new router.
