Hope this is a reasonable place to ask this question. Please point in right direction if not.
Scenario: Assume a regular-Joe wireless laptop user enters some establishment or other which offers freebie wireless Internet connectivity, which he then uses.
What I'd like to know is:
a) Is there any way that whomever is providing the connectivity can - at any point - somehow log any of the software or hardware details of the connecting laptop, in such a way as to be able to uniquely identify the laptop (eg. Windows username, network card info, hard drive serial number, etc, etc) at some future point?
b) I'm guessing this next question would depend on the individual setup of the network, but, assuming the same scenario, would each user on the network generally get the same external IP, or would they likely be different?
Many thanks, Sam
