Using cron to disconnect all users at midnight

jeebsion 0

Hi all,

Is there a way to issue a command (perhaps wrapped via php) to disconnect all captive portal connected users at midnight via cron. Has anyone done this before?

I came through this, found it via google dated back in 2015:

require("captiveportal.inc");

if (!is_array($config['captiveportal'])) {
	$config['captiveportal'] = array();
}

$a_cp =& $config['captiveportal'];
foreach ($a_cp as $captiveportalzone) {
	// set $cp_zone so the correct database will use used
	$cpzone = $captiveportalzone['zone'];
	// also surface the global $cpzoneid
	$cpzoneid = $captiveportalzone['zoneid'];
	// Read the corresponding database
	$cpdb = captiveportal_read_db();
	foreach ($cpdb as $cpent) {
		captiveportal_disconnect_client($cpent[5]);
	}
	unset($cpdb);
}
unset($a_cp);

cat it to /root/test.php and run it like so:

/usr/local/bin/php -q /root/test.php

However to no avail. Would appreciate any pointers at all!

Dono who wrote that code snippet, but it's incomplete ;)

Here you have the entire file :

#!/usr/local/bin/php -q
<?php
	/* Disconnect all clients on all captive portal instances */

	require_once("/etc/inc/util.inc");
	require_once("/etc/inc/functions.inc");
	require_once("/etc/inc/captiveportal.inc");

	global $g, $config, $cpzone, $cpzoneid;

	/* Are there any portals  ? */
	if (is_array($config['captiveportal'])) {
		/* For every portal (cpzone), do */
		foreach ($config['captiveportal'] as $cpkey => $cp)
			/* Sanity check */
			if (is_array($config['captiveportal'][$cpkey])) 
				/* Is zone enabled ? */
				if (array_key_exists('enable', $config['captiveportal'][$cpkey])) {
					$cpzone = $cpkey;
					$cpzoneid = $cp['zoneid'];
					captiveportal_disconnect_all();
				}
	}
?>

The file is updated, as portal 'code' evolved somewhat over the last 7 years.
Global variables have to be setup correctly.
The starting <?php is important.
And instead of the function captiveportal_disconnect_client() we have now captiveportal_disconnect_all() that removes all users from a portal instance.

I tested it.
Thanks ;)
All my connected users (a hotel) were thrown of the portal.

@gertjan Oh my .. sorry I haven't been able to get to this channel for quite some time .. I'll try this out and report back .. thank you, sir!

PS: I don't quite understand the global part .. should be descended from captiveportal.inc yes?
