Php ban, alternate way?

[Marco]

Ok, since u all know people can change ip, use proxies etc, ip banning is less of effect.

Now what i am wondering, using php and/or javascript, is there a way you can get certain sensitive computer sided information.
Like a mac address. Processor information + system name.
combining such information, you should be able to generate a certain code, which could be banned.

The only bypass for such ban would be by reinstalling the computer.
or messing with the computer information, which most people do not dare or do not execute.

The idea for such ban makes me kinda happy.

is there any way to get this information WITHOUT secondairy service requesting the information?
So using only the webhost.

Any langauge possible on the webhost is allowed.

Sadly, the remote computer would have to respond to a request in order for you to obtain more information. But there is more information available to you. By contacting the webhost a computer will share certain information. You already know IP, but the browser type, and a timestamp are also shared. By using this additional information it might be possible for you to block certain users for a time.
Also, if you need to block the user in an active time frame just download a cookie to his computer that causes content to not appear.

Forget the MAC address. The MAC in all packets reaching your webhost will be the router connected to the host.

The remote computer is plain not going to send its system name without a very special request.
