Re-Captcha implementation in php script help needed!

Hi,

I have a site running with a php script for file downloads. But someone is abusing my script and bandwidth of my site Please help me out.

I am ready to pay for this help.

Please pm me for offers if you can do this in shortest possible time.

Waiting for offers,

 

Are u giving direct links ?? or through through php ??

 

I have a script which fetches files from file hosting sites and then my site provides link to download using some random generated link.

But the abuser is sending so many file download requests through different proxies that he wasted abt 100 gb bandwidth in just 1 hour or so..

Please help me. Can u pm ur id?

 

You could use recaptcha.net its really easy to use, here I modified the default script a lil bit. It should work like that!

<form action="" method="post">
<?php

require_once('recaptchalib.php');
$publickey = "...";    //here you need to enter the publickey  
$privatekey = "...";  //and the privatekey that you get from recaptcha.net


$resp = null;
$error = null;

if ($_POST["submit"]) {
  $resp = recaptcha_check_answer ($privatekey,
                                  $_SERVER["REMOTE_ADDR"],
                                  $_POST["recaptcha_challenge_field"],
                                  $_POST["recaptcha_response_field"]);

  if ($resp->is_valid) {
//Here you print the download link

      echo "<a href=\"http://www.linktodownloadfile.exe\">Download</a>";
     
    

  } else {
    
    $error = $resp->error;
  }
}
echo recaptcha_get_html($publickey, $error);
?>
    <br/>
    <input type="submit" name="submit" value="Download" />
    </form>

PHP:

org

 

There's always a psuedorandom string generation. It's a pretty good option. You could also put in a download timeout check on the IP address. Say they dled a file 2 seconds ago then they can't download for xx more seconds. Let me know if you need help.

 

You posted this already in a different forum. I suggested a honeypot technique. Read my original response at: Digital Point Forums > Design & Development > Site & Server Administration > Re-Captcha implementation in php script help needed!

I can't post the regular link yet since my post count/member length is too low.
