Clear old DHCP devices

[cybercowboy]

Let me start by saying I have a very busy house, my wife has friends over, my kids have friends over, relatives come to town and stay with us,and everyone wants to connect to the wifi. No biggy, I've got a QR code printed that they scan and it inputs the password and everything. The problem is Amahi never seems to clear the devices that haven't connected in a while from it's list under networking. Now when I go through trying to troubleshoot a problem and am looking for the ACTIVE devices I have to wade through devices that haven't connected since December (last count I had over 185 devices listed as inactive) to find the 10 or so that are my actual families devices and presently connected.

Is there a way to clear out this list, or to at least filter out the inactive so that I can use the list for its (I assume) intended purpose of giving me information of who's presently connected to my network, or who's been connected within the last week or so?

This is done automatically by the OS. Unfortunately, Ubuntu takes quite a while to do it. Not sure, but you may be able to delete the leases file and restart the DHCP server as a way of purging the list.
