A stiffer Proxy Blocker

Posted: Thu Jul 29, 2004 8:39 am

When coding the Proxy Blocker I made it mild since I didn't have that list of proxies to test it with. Anyway follow the instructions below to increase it's effectiveness.

Open includes/sentinel.php and find:

Code:

// Proxy Blocker


$proxy1 = get_client_ip();


$proxy2 = get_x_forwarded();


if($ab_config['allow_proxy'] == 1 AND ($proxy1 != "none" OR $proxy2 != "none")) {


  $proxy_reason = stripslashes($ab_config['proxy_reason']);


  die($proxy_reason);


}

Now replace that with:

Code:

// Proxy Blocker


$proxy0 = get_ip();


$proxy1 = get_client_ip();


$proxy2 = get_x_forwarded();


$proxy_host = @getHostByAddr($proxy0);


if($ab_config['allow_proxy'] == 1 AND ($proxy1 != "none" OR $proxy2 != "none" OR stristr($proxy_host,"proxy") OR $proxy0 == $proxy_host)) {


  $proxy_reason = stripslashes($ab_config['proxy_reason']);


  die($proxy_reason);


}

This is a much stiffer proxy check and should catch most but not everyone since it's hard to catch everything.

I've had to turn this option off on my site, it wouldnt let any of my regulars on. I guess we must all use proxies.

Is there any way we can allow some and not others?
