When the file /etc/default/dhcp3-server does not exist, then you are not 
using the variant of dhcp3, that is part of Ubuntu. Forget about that 
file, unless you install it from Ubuntu with this command:
	sudo apt-get install dhcp3-server
Please note that you will only get version 3.0.6, I don't know if that's 
enough for your setup.

Going back to the error message you got, the problem is that you should 
also tell dhcpd which interface to listen to. You are probably using a 
command like this to start the dhcpd daemon:
	sudo /usr/sbin/dhcpd -cf /etc/dhcp3/dhcpd.conf

With or without the initial sudo, that's just to ensure that you have 
the correct permissions. Try to add the name of the interface that DHCPd 
should listen to, like this:
	sudo /usr/sbin/dhcpd -cf /etc/dhcp3/dhcpd.conf eth0

That will proably do the trick.
