PHP - Granting Admins Access To Proxy Normal Users

Hi All,

When I put

echo memory_get_usage();

at the very beginning of a php file I get 51207808. Is this normal while there is not much processing to do ? This happens even for very small php files that only display html syntax.

Thanks!

$server = "whois.nic.cz";
$domain = "klikzone.cz";

function QueryWhoisServer($server, $domain){
    $proxy = "85.111.25.189:8080";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $server);
    curl_setopt($ch, CURLOPT_PORT, 43);
    curl_setopt($ch, CURLOPT_PROXY, $proxy);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $domain . "\r\n");
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;  
}

Hi,

I'm trying to understand any how I can block all users trying to view my website through proxies. With the following code, what I have done is a quick version through php (with headers and ports) and not the firewall which isn't exactly the best way but still stops a lot of them.

<?php
$user_ip = $_SERVER['REMOTE_ADDR'];
$headers = array('CLIENT_IP','FORWARDED','FORWARDED_FOR','FORWARDED_FOR_IP','VIA','X_FORWARDED','X_FORWARDED_FOR','HTTP_CLIENT_IP','HTTP_FORWARDED','HTTP_FORWARDED_FOR','HTTP_FORWARDED_FOR_IP','HTTP_PROXY_CONNECTION','HTTP_VIA','HTTP_X_FORWARDED','HTTP_X_FORWARDED_FOR');
foreach ($headers as $header) {
	if (isset($_SERVER[$header])) {
		header("Location: /proxy-not-allowed/");
		die;
	}
}
$queryIP = "SELECT `user_ip_address` FROM `my_table` WHERE `user_ip_address` = :user_ip_address AND `user_blocked` = :user_blocked LIMIT 1";
$queryIP1 = $pdo->prepare($queryIP);
$queryIP1->execute(array(':user_ip_address' => $user_ip, ':user_blocked' => 'No'));
$queryIP2 = $queryIP1->rowCount();
if ($queryIP2 === 0) {
	$ports = array(80, 81, 553, 554, 1080, 3128, 4480, 6588, 8000, 8080);
	foreach ($ports as $port) {
		$connection = @fsockopen($user_ip, $port, $errno, $errstr, 0.1);
		if (is_resource($connection)) {
			header("Location: /proxy-not-allowed/");
			die;
		}
	}
}
?>

The headers script blocks any proxy sending those headers while the ports script blocks those using any assigned ports I add. I have tested this which seems to be good, though it won't block all proxies due to the assigned one I have. Is this the best way to go about blocking scripts if I don't have access to the firewall?

What I am trying to do is allow users to view my HTTPS website normally and block all proxies. Even if I have some users blocked, I do not want them to be cheeky and use a proxy or even register on my website through a proxy. I was thinking of just using the 443 port as my website is https (is that wise?). Any advice would be great.

Hi I need a script to hide  IP address with proxy and read a web page

$username="myuser";
$password="mypass";


$url = "http://www.mysite.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, '173.234.11.134');
curl_setopt($ch, CURLOPT_PROXYPORT,'80');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);




echo $output;
curl_close($ch);
 

The script doesn't work, it doesn't show me the page output. Any solution?
