Cronjob problem

Sorry for yet another post, but I've got yet another problem! I'm trying to setup a cronjob that runs via CI. I checked out the associated wiki entry (http://codeigniter.com/wiki/Category:Adv...ronScript/) and found the information there very helpful.

I setup a folder called cron in my root directory, and copied index.php into it (renaming it cron.php), and made the following changes:

Code:

set_time_limit(0);
    $_SERVER['PATH_INFO'] = '/cron/update_jobs';
$system_folder = "../system";

Where cron and update_jobs are the controller and function being called. However, using the following cronjob command:

php -q /home/part/public_html/wb/cron/cron.php

I receive the following error:

Warning: require_once(../system/codeigniter/CodeIgniter.php): failed to open stream: No such file or directory in ]

.

Now, cron is a folder in the root directory. So ../system _should_ be pointing it in the right direction, but I'm not having any luck! Suggestions?

As for a second question, I found the following suggestion for securing the cron controller on the forum, and wanted input on it:

Code:

function Cron() {
    
        parent::Controller();
        if($_SERVER['SCRIPT_FILENAME'] != '/home/part/public_html/wb/cron/cron.php') exit;
        
        $this->load->model('Job_handler');
        
    }
    
    function _remap($method)
    {
        
        $this->load->library('user_agent');
    
        if( !$this->agent->is_browser() && !$this->agent->is_robot() && !$this->agent->is_mobile()):
            $this->$method();
        else:
            exit('You may not access this file.');
        endif;
        
    }
