This isn't a problem. If you'd like some example code you can
look at my dhcp suite:

http://dhcp-agent.sf.net/

libdnet lets you MAC address spoof fine except for Mac OS X. Dug
mentioned that it doesn't seem to work on that particular UNIX
flavor.

libdnet will happily write to an interface with no IP address. In
fact a dhcp client implementation requires this.

I don't know what advantages you get from libnet. Constructing
your own packets is trivial. Building a stack to respond to
packets is a little more work.

[snip code]

I haven't looked at your code. Mention an actual problem or bug
and subscribers to this list would be happy to help.
