Need help with LEASEQUERY..

Greetings,
I am trying to construct a LEASEQUERY packet in PHP that
I can use to query our ISC DHCP daemon with.

I have gotten as far as seeing the packet show up in a
WireShark packet trace and it looks correct there (I think?).
I never see anything show up in our syslog or on stderr if
ran in debug however.

If I attach to the running daemon with strace (Linux/Fedora),
I can see about four lines come up when the packet arrives,
acknowledging that it received a packet, but it doesn't do
anything with it, just throws it out or so I'm assuming.
I am using packet type 10, not 13 as stated in RFC 4338 and
RFC 2131.

I can try sending a lease query using a Perl script which is
said to work w/ ISC's DHCPd but even with that I see the same
things take place in my packet trace/syslog/strace/etc.

No matter how I go about it, it's still no joy.

I have tried version 3.x and am now on a freshly compiled
version 4.1.1 with pretty much everything enabled.

I do have allow leasequery in my dhcpd.conf.

What else might I be missing or doing wrong?
I know I am close.

Also, is there anything like this already written that I'm not
finding that might save me from re-inventing the wheel??

Thanks in advance for any help offered!
