delegating name servers in Bind9

> Hi
> I'm trying to play with DNS tunnelling and need to setup a name server
> for a subdomain on my network. I'm running Bind9 locally and from what
> I've read the setup should be simple but I can't get it to work.
>
> I've got these lines in my db.attack file:
>
> attack.int.  IN NS digininja.org.
> tunnel.attack.int.   IN  NS  desktop.attack.int.
> desktop  IN A 192.168.0.4
>
> which I think means that anything to attack.int is taken care of by
> the nameserver digininja.org but anything to the subdomain
> tunnel.attack.int should be passed to the nameserver running on
> desktop.attack.int.
>
> I can get an IP for desktop.attack.int but not for tunnel.attack.int
> or *.tunnel.attack.int . I've watched traffic and there are no
> requests coming into desktop so the delegation isn't working.
>
> Can anyone suggest what I'm doing wrong?

Give chapter 9 of O'Reilly's "DNS and Bind" book the once over. 
Specifically the section called "How to Become a Parent: Creating
Subdomains".  If you don't have a copy, you can find a free online version
