Secondarying DLZ zones

[Robert Moskowitz]

It seems I have this working, but...

I have a regular Centos7 Bind 9.9 server that I want to secondary a 
Samba AD (Also Centos7) DLZ zone.

On the DNS server (192.168.192.5) I have:

         zone "home.htt" {
                 type slave;
                 file "slaves/bak.home.htt";
                 masters {192.168.192.2; };
         };

On the Samba AD I have:

dlz "AD DNS Zone" {
     # For BIND 9.9.x
      database "dlopen /usr/lib/samba/bind9/dlz_bind9_9.so";
};

And it seems works.

On 192.168.192.2 I saw:

Sep  7 14:00:05 homebase named[1133]: client 192.168.192.5#51888 
(home.htt): transfer of 'home.htt/IN': AXFR started
Sep  7 14:00:05 homebase named[1133]: client 192.168.192.5#51888 
(home.htt): transfer of 'home.htt/IN': AXFR ended


On the DNS server, 192.168.192.5, I can resolve hosts in the home.htt zone.

But there is no slaves/bak.home.htt file.  Perhaps my notes are old from 
when I did this some years back (and static master zone), but I would 
think that there should be the slaves/bak.home.htt file?

I also need to implement Notify for changes to the home.htt zone.

thanks
