OK DNS - my Best Thing

in db.dm0nkz.net:

home-woody	A	192.168.0.1

hanz-woody	A	x.y.z.a (You didn't say what hanz-woody's
											IP address is)

vhostb				CNAME	hanz-woody

(this works, since hanz-woody, without the trailing ., will have the default
domain for this zone file appended automagically, and becomes hanz-woody.dm0nkz.net)

alternatively,

vhostb			CNAME	hanz-woody.dm0nk.net. (is how most bind purists would do it.
 															Note the trailing . to prevent appending the default
															domain for the zone file.)

in db. testing.org

vhosta		CNAME	hanz-woody.dm0nk.net. (the FQDN with the trailing . is required
																					here)

Also, you have to be the primary nameserver for testing.org for this to work.

Finally, in named.conf:

 zone "dm0nkz.net" { 
         type master;
 	file "/etc/bind/db.dm0nkz.net";
 };

zone "testing.org" { 
         type master;
 	file "/etc/bind/db.testing.org";
 };

Once again, assuming you are primary for testing.org . . .
