Below I wrote down a simple PHP script that saves client IP address to a file. If the IP address of your home machine periodically changes, you can store it on a web server once a minute by scheduling a task like this:
sudo crontab -u <user> -e
* * * * * wget -q -O /dev/null -o /dev/null "https://yourwebsite.com/ip.php?rig=rig1&password=XXXXX"
where ip.php is the following PHP script:
<?php
//print_r($_GET);
function getRealIpAddr()
{
if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share internet
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy
{
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
$clients = array("rig0", "rig1", "rig2", "rig3", "rig4");
$client_password = "XXXXX";
if ($_GET["password"] == $client_password && in_array($_GET["rig"], $clients))
{
$ip = getRealIpAddr();
echo $ip;
$file = "./rigs/" . $_GET["rig"] . ".txt";
file_put_contents($file, $ip);
}
else
{
echo "Access denied.";
}
?>
