+Under [Debian] [Woody], you install "dhcp-client" for clients, and "dhcp" for the server. If you have interfaces other than eth0 and lo0 (such as wan0 for MetaNet), then by default dhcp will refuse to start. You need to edit /etc/default/dhcp and put __INTERFACES="eth0"__. Unfortunately this isn't documented anywhere sensible like the dhcpd man page or the README.Debian file.

+In /etc/dhcpd.conf, the options that take time values are in seconds, although the example file doesn't mention this. It's in the man page though, dhcpd.conf(5)

!! Dynamic DNS

-First of all, you *need* dhcp 3 and above. This is the default dhcp package in recent RedHats
, in Debian Woody you want the dhcp3-server package.
