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.

updates and cause data to be lost.
Unfortunately, 'nsupdate' is about as much fun to use as 'nslookup'. More on 'nsupdate' once I've figured out how to use it, and what to do with those pesky .jnl (journal) files getting out of synch with the zone.

+You can actually edit the zones, but 'named' must first sync the .jnl journal files with the database, and stop any further changes from taking place during the edit - this is only possible after a full, graceful shutdown of the 'named' daemon. This can be forced by using
+# rndc stop
+
+After editing your zones, restart 'named' as usual. Often, this is done by:
+# named -u (user named runs as)
