He didn't originally leave his wireless open to "bait" people. Some one started stealing it. From what it sounds like the op didn't leave the wireless unsecured for malicious reasons.
If that is your premise then how are honeypots not illegal?
I could tell you about the anarchist cook book, and you could go out on your own and use it for bad things, does that make me legally responsible? No, it does not.
You aren't grasping what I am saying here, and perhaps I am not writing it out clear enough.
Are free wifi spots illegal in anyway? NO, definitely not.
When people use free wifi for malicious and illegal activities, does that make the free wifi illegal? No
If you purposely bait people, or hell don't even look at it that way, if you are allowing people on your free wifi and then spying on them, is it illegal? Yes, and it leaves you wide open for civil suit, even if is not illegal for some reason or another (like a loop hole).
Your right, however they are not on an open free wifi spot. The neighbor is breaking the law and stealing his wifi, which has court cases backing up that it is illegal.
I still disagree with:
It brings me right back to the honeypot.
try wireshark
takes a while to get used to. we used it in school, just to monitor our own traffic, packages and all that fun stuff. but ive been told it can monitor the network too, but i never tried.
its kind of a bitch to setup though
finally a real answer, thanks i'll check it out, it'll just let me see how many packets are being sent? or what?
Your router will show you who is connected but not what they are doing. To figure that out you would have to change the color of your hat.
Hmmm this discussion almost seems pointless. OK, so you know that it's your neighbors that are leaping onto your unsecured network...hey just walk over and look over their shoulders when they're online using YOUR network. What's the real reason that you want to track what they are doing on your NETWORK? I lock my car because I don't want to have to "track" where the person that decides to use it because I left it unlocked, decided to drive it to. I bet I know who could probably answer your question..try asking the FBI or CIA.
