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).
-If you are running a dhcpd server on Debian Woody, and you're running [LinuxKernel2.6], then you will need to edit /usr/sbin/dhcpd and add a "6" where it says [[12345]. When the script was written, it was unsure whether or not the 2.6 kernel would have compatible structures for the binary in the dhcp package, but it works fine in 2.2 - 2.6 kernels.

Note: it is very important that you copy the key verbatim!
For the zones you wish to enable DDNS updates on, add the following to the zone definition in named.conf
- allow-update { key DHCP_
UPDATER; };
+ allow-update { key DHCP-
UPDATER; };
e.g., I have:
zone "dyn.mydomain.something." {
type master;
file "/etc/bind/zone/db.dyn.mydomain.something";
- allow-update { key DHCP_
UPDATER; };
+ allow-update { key DHCP-
UPDATER; };
};
Remember to add it to the reverse zone as well:

This sets up the ddns keys, and which zones to use them for. ddns-domainname sets the forward domain name that ddns will update. You can leave this out,
