Help me stop DDoS

1. QuyCuong (07.05.2013 / 07:43)
Can you help me write a script that hits the limit
time for 3.x rotorcms. I want some smaller hits
500. If you exceed the 500 will notice the entrance: the site is overloaded, please visit a few minutes

    function server_busy($numer){
    if (PHP_OS == ‘Linux’ AND @file_exists(‘/proc/loadavg’) AND $filestuff =@file_get_contents(‘/proc/loadavg’)){
    $loadavg = explode(‘ ’, $filestuff);
    if (trim($loadavg[0]) > $numer) {
    print ‘the site is overloaded, please visit a few minutes….’;
    exit(0);
    }
    }
    } 

    $srv = server_busy(500);
?>

I'm using 3.3.2 Rotorcms
code above does not work, please help me edit it,

500 - is a very very lot.
$srv = server_busy('5.00');
if load average > 5 (5.00) or 10, it is time to take action...
when load average is 500 server will not work ;-)

4. shilo,
I do not understand what you say

6. shilo (07.05.2013 / 10:54)
$srv = server_busy('5.00');

^ That's done, 500 is a lot.
Кто на инглише свободно говорит, объясните ему что 500 это очень очень много, сервер с такой нагрузкой со свистом вылетает из стойки

7. Вячеслав (07.05.2013 / 11:17)
asked to explain...
$srv = server_busy(500); // is a server with 500 processor cores, you really have such a server?

otherwise do not run on a server with four cores, because max "loadavg" for him <= 8

Please write to function fully, I will correct it

12. QuyCuong (08.05.2013 / 09:16)
includes/function.php

    function server_busy($numer){
    if (PHP_OS == 'Linux' AND @file_exists('/proc/loadavg') AND $filestuff =@file_get_contents('/proc/loadavg')){
    $loadavg = explode(' ', $filestuff);
    if (trim($loadavg[0]) > $numer) {
    print 'server busy, Please wait….';
    exit(0);
    }
    }
    } 

    $srv = server_busy('5.00');
?>

Thanks

12. QuyCuong, Checked out your function, it works.
Maybe file /proc/loadavg is not readable?

14. shilo (08.05.2013 / 10:00)

<?php
function server_busy($numer){
    if (PHP_OS == 'Linux' AND @file_exists('/proc/loadavg') AND $filestuff =@file_get_contents('/proc/loadavg')){
        $loadavg = explode(' ', $filestuff);
        if (trim($loadavg[0]) > $numer) {
                echo 'server busy, Please wait.';
                exit(0);
        }
        # :D EBUG
        # else {
        #       echo "OK";
        #}
        return trim($loadavg[0];
    }
}

$srv = server_busy('1.00');
?>

<?php
function server_busy($numer){
    if (PHP_OS == 'Linux' AND @file_exists('/proc/loadavg') AND $filestuff =@file_get_contents('/proc/loadavg')){
        $loadavg = explode(' ', $filestuff);
        if (trim($loadavg[0]) > $numer) {
                echo 'server busy, Please wait.';
                exit(0);
        }
        # :D EBUG
        # else {
        #       echo "OK";
        #}
        return trim($loadavg[0];
    }
}

$srv = server_busy('1.00');
?>

It does not work, 501 hits without notice : Server busy , Please wait...

You probably do not quite understand what the script does ...
His script displays an error if the server is overloaded. it does not function as antiddos.

17. QuyCuong (08.05.2013 / 17:39)
for example, I rather $ s r v = s e r v e r _ b u s y ( ' 1 . 0 0 ' ) ; In order to check, why? I
want test some hits in 10 people

To eliminate such problems should the administration of your server.
P.S. I do not speak English. But I think what you understand me.
