 ====== Block devices via script/Scheduler ======
-The easiest way to filter WiFi devices is to use the [[basic-wfilter|Wireless Filter]] menu. However, there are times when you want to block specific devices via a script. This is particularly true when you need to manage device blocking for a lot of devices. Scripting also allows you to schedule blocking/filtering on or off, as needed.

 ===== Notes =====
-Still, the kernel resolves the hostname to an IP address. A device with randomized MAC address will obtain a new IP address when reconnecting. This might function well, but only until the user restarts the device or just manually disconnects WiFi.

-If you're very security conscious, you could trigger a "service wireless restart" for each new client connecting, but that would be disruptive to the general network.

 For WiFi devices, perhaps the best way to limit access is to make them connect to a dedicated SSID, and enable/disable that SSID as needed. For details about this approach, see the HOWTO: [[toggle_radio|Turning on/off radio elements from script]].
