Hi,
When I get the CF API working reliably I will, I don’t want to share shoddy code. Haha.
The main bit that’s working well is an action that logs IPS to a file, then a WP filter that prevents PHP execution:
actionban = echo <ip> | awk -F\. '{print ($4)+($3*256)+($2*256*256)+($1*256*256*256) d}' "d=,$(date)" >> /etc/agilis-banned-ips
(storing in int format for speed)
function agilis_login_filter_ips() {
$handle = fopen("/etc/agilis-banned-ips", "r");
if($handle) {
while(($line = fgets($handle)) !== false) {
$linearray = explode(',', $line);
if(count($linearray) > 0 && ip2long(agilis_get_ip()) == $linearray[0]) {
echo '<h2>Banned</h2>';
echo '<p><strong>IP:</strong> ' . long2ip($linearray[0]) . '</p>';
if(count($linearray) > 1) { echo '<p><strong>Since:</strong> ' . $linearray[1] . '</p>'; }
echo '<br/><em>Agilis Login Filter</em>';
if(function_exists('http_response_code')) {
http_response_code(503);
} else {
header((isset($_SERVER['SERVER_PROTOCOL']) ? $_SERVER['SERVER_PROTOCOL'] : 'HTTP/1.0') . ' 503 Service Unavailable');
$GLOBALS['http_response_code'] = 503;
}
exit;
}
}
} else {
echo 'Error reading file';
}
fclose($handle);
}
add_action('login_form_login', 'agilis_login_filter_ips');
