Setting up Dynamic DNS for a LAN

B

bit

Hi,
I'm attempting to set up a dhcp server able to update dns to server IP addresses on my home network but I'm having some issues get the DNS entries updated when a DHCP lease is handed out. I have verified that the DHCP server is working (it's correctly handing out leases) and that the DNS server is likewise (at least, I know its able to retrieve records via my router and hand them out to clients on the network).

I've been using this guide to help me, http://www.semicomplete.com/articles/dynamic-dns-with-dhcp/

At boot I'm getting the following error which I'm guessing has something to do with the issue but as far as I can tell managed-keys.bind is where it's supposed to be.
managed-keys-zone ./IN: loading from master file managed-keys.bind failed: file not found

The name of the machine I'm setting up as dhcp/dns server is "nroute" with an IP address 192.168.1.5 while my routers local port is 192.168.1.1

named.conf is at /etc/namedb and has the following directory structure:

Code: 
drwxr-xr-x  2 bind  wheel   512 Jan  3  2012 dynamic
-rwxrwxrwx  1 root  wheel     0 Dec  5 23:44 managed-keys.bind

Would someone mind having a look at my configuration and seeing if there's anything obviously bad? I know the secret but as it may be part of the problem and I can regenerate it, I don't see much point obfuscating it.
