Frustrating... I've got all of my zones working with the exception of the 168.192.in-addr.arpa. I've cross referenced the two 0.0.127 and 168.192 files, and can find no differences between them as to why one should work, and not the other. What I'm getting when starting named is this: Mar 1 20:08:33 wormy /usr/sbin/named[30907]: dns_zone_load: zone 168.192.in-addr.arpa/IN: could not find NS and/or SOA records Mar 1 20:08:33 wormy /usr/sbin/named[30907]: dns_zone_load: zone 168.192.in-addr.arpa/IN: has 0 SOA records Mar 1 20:18:35 wormy inetd[82}: netbios-ns/udp server failing (looping), service terminated Section from named.conf file referencing the 168.192 zone: zone "168.192.in-addr.arpa" in { type master; file "db.192.168"; }; Top part of db.192.68 $TTL 3h @ IN SOA wormy.mn-ttkd.org. sfertch.real-time.com.
