Hy all.

i have a little problem, i have here a wifi hotspot, this hotspot need an account to surf with it. If i try to connect to the hotspot with my iphone, i god an IP and then opens up a window / webpage, its says, please enter your account data.... if i disaccept this by clicking on cancle, my wifi connection to the hotspot is killed.

now what i want to try:

I will connect to the hotspot, cancel the auth event and then open the shell (on iphone) and make a arp attack. But i cant hold open the connection to the hotspot ;(

Any Ideas ?

A window appears... where? In safari when you try to connect to some site? Does it open up as soon as you connect to the hotspot?
However, if you can stop that login page, and stay connected.. you just have to search on google for "http tunneling". I've compiled an app for my iphone for this purpouse, but I still have to test it. However, if you choose the "tunneling" way, you're likely to have just to install a toolchain on the iphone, download the source of a program you like that does this kind of things, and compile it.
Good luck!
