Please review master-file syntax:
1) Any name which is not dot-terminated will have the $ORIGIN appended to=
it
(which is why, for instance,"localhost" is being interpreted as
"localhost.0.168.192.in-addr.arpa").
2) NS records take names, not IP addresses (which is why, in conjunction =
with
the above problem, the "slums" NS record "192.168.0.1" is being interpret=
ed as
"192.168.0.1.slums").
Also, you said you installed BIND 8.0, but actually the logs indicate tha=
t it
is BIND 8.2.2-p5. You should probably upgrade to BIND 8.2.2-p7 or later f=
or
security reasons.
Lastly, you can get rid of the "No default TTL" error messages by putting=
a
$TTL directive at the top of all your master files (see
http://www.nominum.com/resources/faqs/bind-faq.html#nottl for more detail=
s).
