Hii,
I need to know is there any way to get the mac id's of the machines accessing ma site! I want to make a access lock using the mac id's -
<?php
-
function returnmacaddress() {

// 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';
-
$location = rtrim($location);
-
// Execute the arp command and store the output in $arpTable
-
$arpTable = '$location -n';
-
// 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 = $_SERVER['REMOTE_ADDR'];
-
$remoteIp = str_replace(".", "\\.", $remoteIp);
-
// Cicle the array to find the match with the remote ip address
-
foreach ($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;
-
}
-
echo returnmacaddress();
-
?>

then it’s probably returning false, which does not have a print representation (check with var_dump()).

hasn’t there been a description?
besides the code usage looks odd.
this is what I found somewhere else and looks way more sensible. - $mac = `ping $ip && arp -a | grep $ip`;

to know what arp does go to a posix machine (linux, unix, bsd, mac), open a terminal (on linux you can also use ALT+F2), type
hit enter and read the description.

so we cannot generally find the MAC id's of a machine connected to net as one of the problems will be permission!

do you get the same result if you try - $mac = `arp -a | grep $ip`;
?
