OMG - Spam on my new site

[Danny]

My is not even index by google and I got so much spam already. I check my comment table and I saw that their ip_numbers (not ip_address) are 0s (zero).

I used ip2long to convert the ip_address to ip_number {ip2long($_SERVER['REMOTE_ADDR'])}.

How come their IPs are 0s?

Hi everyone. Great site. Hold on.

I am not sure why you would want to convert the IP address to a long data type? Wouldn't you want to see it as xxx.xxx.xxx.xxx?

Regardless, the following should work

PHP Code:

$referrer_ip = getenv(REMOTE_ADDR); 
$ip_address =ip2long($ip); 


Or, if you are on versions of php earlier than 5.0:

PHP Code:

$remote_ip = getenv(REMOTE_ADDR); 
$ip_extract = explode (".",$remote_ip);
$code=($ip_extract[0] * 16777216) + ($ip_extract[1] * 65536) + ($ip_extract[2] * 256) + ($ip_extract[3]); 


If you want to see it as xxx.xxx.xxx.xxx, then:

PHP Code:

$referrer_ip = getenv(REMOTE_ADDR); 


If you want to grab each octet of the IP address:

PHP Code:

 $remote_ip = getenv(REMOTE_ADDR); 
$ip_extract = explode (".",$remote_ip);


$octet1 = $ip_extract[0];
$octet2 = $ip_extract[2];
$octet3 = $ip_extract[3];
$octet4 = $ip_extract[4]; 


I hope that helps

The reason I am using ip2long is because I implemented maxmind ip-country database on my system.

maxmind using ip number instead of ip address. So I like to use ip number as well for the ease and robustness of comparison.

There shouldn't be any problem as my server uses the latest version of PHP. But, I'll try your method.

I also need to implement captcha to minimize the spamming.

I don't know why it wouldn't work, then... I would do an echo of the 'REMOTE_ADDR', then, to see if the problem starts there. There is a breakdown somewhere and it is either in the function or in the IP address itself.

Look, my ip address/number is shown correctly. I even try different IPs. I don't know why their ips doesn't shown!

Here's a little function I found that might help you out:

PHP Code:

function GetIP()
{
   if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
           $ip = getenv("HTTP_CLIENT_IP");
       else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
           $ip = getenv("HTTP_X_FORWARDED_FOR");
       else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
           $ip = getenv("REMOTE_ADDR");
else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
           $ip = $_SERVER['REMOTE_ADDR'];
       else
           $ip = "unknown";
   return($ip);
} 


Now use the GetIP() function to return the IP and then convert it to a long data type.
