[Dnsmasq-discuss] trouble setting up dnsmasq as local dns + dhcp server on ubuntu

[Steve Romanow]

Hi guys,

I have an install of dnsmasq 2.33-1 on ubuntu edgy.  I have had this partially 
working for a couple of months, but it appears the wheels have come off.

The server was multihomed for a short time as I was setting up a webserver 
bound to eth0 for external use and eth1 for internal use.  Apache is no 
longer running, but what started out as one or two devices not playing well 
with dhcp has now moved into local dns caching not working at all.

I really do not want to use static ip's.  Right now what I have is a mix of 
static and dynamic ip's.  the machines that _have_ to be resolved are static, 
and less important devices are still dynamic, with ip reservations based on 
MAC address.

local dns is completely borked right now.  Thank you for any advice you guys 
can give.  I have made sure that I do not have bind running, competing with 
dnsmasq.

Here are the pertinent files, with MAC addresses changed.
