Added some quick code to turn on and off various "bot blocking code" based on the load average of the site.

Very simple example:

Code:

<?php
$quickload = getLoad();
if ($quickload > 6) {
    $checkbot = "SELECT bot_flag, country_iso2 FROM session WHERE country_iso2 IN ('RU','CN','KR','KP','UA','TW') AND userid = 0 AND host ='" . $ipFilter . "' LIMIT 1";

    $session_info = $vbulletin->db->query_first($checkbot);
    if ($session_info['bot_flag'] == '1' && $session_info && NEO_SEND_SOME_BOTS_TO_403) {
        $file = '/var/log/apache2/debug/neo_global_country_bot_block_403.log';
        if ($neo_global['debug_block_with_403']) {
            error_log(date(DATE_RFC822) . ' SEND 403 Page: ' . $_SERVER['REMOTE_ADDR'] . ' Country: ' . $session_info['country_iso2'] ." Load: ".$quickload. "\n", 3, $file);
        }
        header($_SERVER["SERVER_PROTOCOL"] . " 403 Forbidden", true, 403);
        include '/var/www/status/403.html';
        die;
    }
}

function getLoad()
{
  $string=file_get_contents('/proc/loadavg');
  $loadavg=explode(' ', $string);
  if($loadavg[0]){
        return $loadavg[0];
  }else{
        return 0;
  }       
}

botti

botti(1)						      General Commands Manual							  botti(1)

NAME

       botti -- Run an irssi module, such as a bot, without a UI

SYNOPSIS

       botti [OPTIONS]

DESCRIPTION

       This manual page documents briefly the botti command.

       Botti allows for you to run an irssi module without a UI.  This is most useful for bots, and by default botti will load the "bot" module.

       This manual page was written for the Debian distribution because the original program does not have a manual page.

OPTIONS

       --config
		 Specify the configuration file location. By default, it is ~/.irssi/config.

       --home
		 Specify the irssi home directory location. By default, it is ~/.irssi.

       -l     --load
		 Specify a module to load. By default, it is "bot".

       --session
		 Option used by the /UPGRADE command.

       -?     --help
		 Print instructions.

       --usage
		 Print simple usage instructions.
