[Dnsmasq-discuss] Detecting when a DHCP client disconnects

[James Harvey]

I'm trying to detect when a DHCP client state changes, and invoke a script.
The dchp-script option works great for new/old leases, but I need to know
when client is not longer connected/reachable. Lease duration is 12h
currently.

I'm keen to avoid having a heartbeat ping out to the client list, but can't
think of an alternative.

Any suggestions of how to do this would be appreciated.

Thanks
