vps被cc攻击如何解决

vps被cc攻击的解决方法

1.首先,在vps网站根目录中新建一个ip.php文件;

2.ip.php文件创建好后,打开,并文件中添加以下内容,用于查找出cc攻击的源IP;

<?php

$real_ip = getenv(‘HTTP_X_FORWARDED_FOR’);

if(isset($real_ip)){

shell_exec(\"echo $real_ip > real_ip.txt\");

shell_exec(\"echo $_SERVER[\'REMOTE_ADDR\']> proxy.txt”);

}else{

shell_exec(\"echo $_SERVER[\'REMOTE_ADDR\'] > ips.txt”)\"

}

echo

?>

3.cc攻击的源IP查找到后,重新在vps网站根目录中新建一个ban.php文件;

4.最后,ban.php文件创建好后,在文件中添加以下内容,对IP进行封禁便可;

<?

$threshold = 10;

$ips = array_count_values(file(\'ips.txt’));

$ban_num = 0;

foreach($ips as $ip=>$num){

if($num > $threshold){

$ip = trim($ip);

$cmd = “iptables -I INPUT -p tcp --dport 80 -s $ip -j DROP”;

shell_exec($cmd);

echo “$ip baned! ”;

$ban_num ++;

}

}

$proxy_arr = array_unique(file(\'ips.txt’))\'

foreach($proxy_arr as $proxy){

$proxy = trim($proxy);

$cmd = “iptables -I INPUT -p tcp --dport 80 -s $ip -j DROP”;

shell_exec($cmd);

echo “$ip baned! ”;

$ban_num ++;

}

echo “total: $ban_num ips ”;

?>
