Hi

I am looking for the code that generates the value of REMOTE_ADDR so that I want to make a code that gives the MAC address of the visitor and I am looking into http://lxr.php.net but I don´t found nothing, if some can help me ... :-)

Regards

Iván Rodriguez Espada

The MAC address is only available on the same network, but you could
always read the headers (php.net/getallheaders). This is the wrong list,
BTW.

Not in the PHP Source, you'll have to find the source of IE or Mozilla 
in order to do something. This is something totally related to the 
client side, and not to the serverside (apache, php, mysql).

Of course not, who is supposed to show PHP (on the server) the MAC 
address? right, the CLIENT, or also called the Browser. Now, as this is 
impossible UNLESS you hackup the browser... wrong list. (And killfile)
