I was just looking for the same thing
A user has an app that works from the internet but not from my companies wireless network. Our wireless has a firewall and a proxy. I dont care if the interface is promiscouious or not as I only want to capture my own traffic so I can compare working and not working traffic patters. I dont care if I can analyse it on the iPad as long as the output is wireshark compatiable I'm happy. I've checked the app store and found nothing, how about in the Jail broken world? My iPad3 is not currently broken, I do have one that is, just to see whats out there but it's an iPad1, as it mostly does everything I want/need as it is.
Thanks in advance
Tom
