[Dnsmasq-discuss] Pulling DHCP leases from an external script?

[richardvoigt at gmail.com]

Non-authoritative summary:

Data goes from the dnsmasq server, to an dnsmasq helper process with
limited privileges, to the script.

No data comes back from the script, except during the startup phase.  This
is a security feature.
