Blocked IP: unknown?

Open includes/sentinel.php in a text editor and find the function get_ip(), it is as follows:

Code:

function get_ip() {


  $client_ip = get_client_ip(); // HTTP_CLIENT_IP


  $x_forwarded = get_x_forwarded(); // HTTP_X_FORWARDED_FOR


  $remote_addr = get_remote_addr(); // REMOTE_ADDR


  if (isset($client_ip) && $client_ip != "none") {


    return $client_ip;


  } elseif (isset($x_forwarded) && $x_forwarded != "none") {


    return $x_forwarded;


  } elseif (isset($remote_addr) && $remote_addr != "none") {


    return $remote_addr;


  } else {


    return "none";


  }


}

This needs to be updated to

Code:

function get_ip() {


  $client_ip = get_client_ip(); // HTTP_CLIENT_IP


  $x_forwarded = get_x_forwarded(); // HTTP_X_FORWARDED_FOR


  $remote_addr = get_remote_addr(); // REMOTE_ADDR


  if (isset($client_ip) && !eregi("none", $client_ip) && !eregi("unknown", $client_ip)) {


    return $client_ip;


  } elseif (isset($x_forwarded) && !eregi("none", $x_forwarded) && !eregi("unknown", $x_forwarded)) {


    return $x_forwarded;


  } elseif (isset($remote_addr) && !eregi("none", $remote_addr) && !eregi("unknown", $remote_addr)) {


    return $remote_addr;


  } else {


    return "none";


  }


}

This is an IMPORTANT patch as it is not correctly reading the x_forwarded_for ip in some cases!
