[Dnsmasq-discuss] Debugging

[Brian Rak]

Is there any way to get additonal debugging information out of dnsmasq?  
I'm running into an issue where I'm seeing 'DHCPDISCOVER(eth0) X Y no 
address available', but it's not particularly clear to me why this is 
happening.  Is there a way to log the contents of the DISCOVER packet?  
I know I can use tcpdump, but that doesn't show me what dnsmasq actually 
thinks is in the packet.

In my case, I should be seeing a subscriber-id in the packets.  I see it 
in tcpdump, but I'm not clear if dnsmasq is actually parsing it.
