hello @denischenu and thank you for your continued interest. I'm happy about that.

I don't know how to make a lite plugin out of:

'log' => array(
'routes' => array(
'fileError' => array(
'class' => 'CFileLogRoute',
'logFile' => 'tokenaccess.log',
'levels' => 'warning, error',
'categories' => 'plugin.logToken.Error',
),
),
),

No,

PLugin must be here only to add the
In onSurveyDenied event.

After you can update config.php to log in on a specific file and use fail2ban configuration to disable IP access to whole system.

Alternative : create a more complete plugin to disable access directly in onSurveyDenied event.

So appreciate your efforts to help me DenisChenu. Really, I do. You are great, but my coding skills are very primitive. I need to see a single file that contains all the necessary commands as a plugin - I cannot figure out how to glue the pieces together.

From what I see of existing plugins there is one file that is the plugin. You examples, are they just one file or multiple files?
