Is it possible to identify the MAC address of visitor?

[Jade]

Is it possible to identify the Mac address of visitor through a php code? I couldn't find a solution for it.

I dont think it is possible to get the MAC address of a visitor, as the connections are passed through firewalls and also there is a use of ISP's Router in establishing an internet connection. However you can make use of ActiveX control or Java scripts to run on the visitors machine and get the MAC Address

Also can I know why do you need to know the MAC Address of your visitors? I am asking this as I'm just curious to know about that

Hey Jade.

I guess this is somewhat impossible as the communication over the Web is through the IP and that also the public IP, MAC Address is never exposed to the web.

I would suggest you to chill :dancing: , don't try to attempt this. One day you will find that you have lost all your visitors due to banned domain :eek: .

I don't think people visiting your site would be too pleased if you obtain their Media Access Control address.

It can also be spoofed as easily as an IP address.

At the end of the day. Why do you need it?

If you want to obtain the MAC from a device connected on your local network, then yes that is possible. Quite Easy.

Hi Thomas

Actually I heard that data link layer bind mac address with frame for recognize to which device that frame handed over, after this I was interested to know the process of Identifying MAC address, but its ok nothing serious if I couldn't do it.

Jade, I think that you have misunderstood the concept of getting the MAC address through a PHP script and the working of Data Link Layer

Actually the thing you are talking about in this post involves the functioning of the 2nd Layer - Data Link Layer. Data Link Layer is a part of the OSI Reference Model, which is a set of rules and regulations by the Open System Interconnections.

hi,
Use the following script to get the mac address using php
<?php
/*
* Getting MAC Address using PHP
* Md. Nazmul Basher
*/

ob_start(); // Turn on output buffering
system(‘ipconfig /all’); //Execute external program to display output
$mycom=ob_get_contents(); // Capture the output into a variable
ob_clean(); // Clean (erase) the output buffer

$findme = “Physical”;
$pmac = strpos($mycom, $findme); // Find the position of Physical text
$mac=substr($mycom,($pmac+36),17); // Get Physical Address

echo $mac;
?>

Hi,


I think you can find the mac address from the given below function.

function returnMacAddress() {
// This code is under the GNU Public Licence
// Written by michael_stankiewicz {don't spam} at yahoo {no spam} dot com
// Tested only on linux, please report bugs

// WARNING: the commands 'which' and 'arp' should be executable
// by the apache user; on most linux boxes the default configuration
// should work fine

// Get the arp executable path
$location = `which arp`;
// Execute the arp command and store the output in $arpTable
$arpTable = `$location`;
// Split the output so every line is an entry of the $arpSplitted array
$arpSplitted = split("\n",$arpTable);
// Get the remote ip address (the ip address of the client, the browser)
$remoteIp = $GLOBALS['REMOTE_ADDR'];
// Cicle the array to find the match with the remote ip address
foreach ($arpSplitted as $value) {
// Split every arp line, this is done in case the format of the arp
// command output is a bit different than expected
$valueSplitted = split(" ",$value);
foreach ($valueSplitted as $spLine) {
if (preg_match("/$remoteIp/",$spLine)) {
$ipFound = true;
}
// The ip address has been found, now rescan all the string
// to get the mac address
if ($ipFound) {
// Rescan all the string, in case the mac address, in the string
// returned by arp, comes before the ip address
// (you know, Murphy's laws)
reset($valueSplitted);
foreach ($valueSplitted as $spLine) {
if (preg_match("/[0-9a-f][0-9a-f][:-]".
"[0-9a-f][0-9a-f][:-]".
"[0-9a-f][0-9a-f][:-]".
"[0-9a-f][0-9a-f][:-]".
"[0-9a-f][0-9a-f][:-]".
"[0-9a-f][0-9a-f]/i",$spLine)) {
return $spLine;
}
}
}
$ipFound = false;
}
}
return false;
