[plug] Dynamic DNS configuration

[Steve Boak]

Hi All

I'm trying to configure dynamic DNS on a (Debian Woody) server with several 
windoze boxes attached on a private lan. I already use dhcp to give out IP 
addresses, and that works well, but I would like to get the hostnames into 
DNS for ease of talking to the windows machines from the Linux end. The IP 
addresses do change occasionally as machines are changed around on the 
network.

I would like to get this working as a learning exercise anyway, but is there 
an easier way that I haven't thought of?

I have added the following to dhcpd.conf:

ddns-update-style interim;
ddns-domainname "nannuptc.org.au";
ddns-updates on;
deny client-updates;
allow unknown-clients;

and added the 'allow-update { localhost; };' line to named.conf:

zone "localhost" {
        type master;
        file "/etc/bind/db.local";
        allow-update { localhost; };
};

My question is, have I done the right thing in adding the 'allow-updates' line 
in the localhost zone, or is this a recursive no-no? Do I need to define a 
new zone for my domain to put this in?

I don't have any test results as I won't be able test this until I am on site 
tomorrow.

Thanks

Steve
