Well, you might get answer(s) sooner and/or get better answer(s) on/with
some list(s)/forum(s), ...
I peeked a bit more at the ISC DHCP server (
). I don't quickly/easily find anything much beyond logging configurations
and debug option(s). Perhaps cranking up the logging level and/or directing
that to file (or pipe, etc.) may suffice. When all else fails, it does
come with source. :-)
