Hi everybody,

Hallo zusammen,

ich möchte die MAC Adresse der Netzwerkkarte des Benutzers auslesen.
Ist das mit PHP möglich und wenn ja, wie?

Danke..

I want to read the MAC address of users' network cards. Is that
possible in PHP, and if so, how?

No, it's not possible - HTTP doesn't work like that (why not have a
read of the protocol specs at www.ietf.org/www.w3c.org)

I can't see a reason why you'd need this kind of information, unless
you're up to something strange! Why do you need the MAC address
in a PHP script?

You might need the MAC address in some cases. Where I live, students may
register their nic to gain internet access. This is done by linking the MAC
address to a student usercode. Only registered nic's get a working IP
address, others stay on a private LAN.

It makes sense to get the MAC address automatically, since most people don't
know where to look for a MAC address.

But, to come to the point, it is NOT possible. MAC addresses are only send
over local networks. The moment a packet is routed, the MAC address
changes. So there is no way you can retrieve the a users MAC address.

Proxy ARP...

More to the point, though, is that if you *need* the MAC address, you
should be able to use a native binary to pass it out over the network
by some other mechanism. HTTP is not the means to find a MAC address!

OK Thank you everybody.. I want to use MAC adress for fail safe user
(re)detection for a payment system
Is there another way to do that?

SSL and login?

If it's an app running on their system, you could have something native
that runs there and keys to their MAC address - Zend use something like
that for their trial license files
