I am trying to exclude specific operating systems from being displayed. I am trying to exclude printers and windows machines. The code I am using in my config.php does not seem to be working. Am I missing anything?
$config[‘os’][‘Microsoft Windows’] = 0;
$config[‘os’][‘Symbol AP’] = 0;
$config[‘os’][‘Xerox Printer’] = 0;
$config[‘os’][‘HP Print server’] = 0;
$config[‘os’][‘Lanier Printer’] = 0;
$config[‘os’][‘OKI Printer’] = 0;

./validate.php

Why not just delete the devices?

Because they keep coming back.

Because you’ve got auto discovery enabled, look at the eventlog for the device and it will tell you why it was added.

Most likely just need to blacklist the IPs from auto discovery - it’s in the docs.

Laf,

Thank you for your reply. Please excuse my ignorance where is the file located and how do I blacklist the IPs?
