Hi,

I’m the maintainer for Kea and ISC-DHCP on OpenWRT.  The scripting to take the 
UCI configuration files for DHCP and mangle them into Bind zone transfers is 
here:

https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L136-L186
https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L274
https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L276

https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L569
https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L575

https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L581-L606
https://github.com/openwrt/packages/blob/master/net/isc-dhcp/files/dhcpd.init#L694

and the glue in Bind is here:

https://github.com/openwrt/packages/blob/master/net/bind/files/bind/named.conf#L8-L9

An example is running locally here, where I have “redfish-solutions.com 
<http://redfish-solutions.com/>” and “168.192.in-addr.arpa” as the domains I 
serve.

And both zones were primed via these commands:

rndc addzone redfish-solutions.com. '{
 type primary;
 file "/var/run/dhcp/db.redfish-solutions.com";
 update-policy {
   grant local-ddns zonesub any;
 };
};'

rndc addzone 168.192.in-addr.arpa. '{
 type primary;
 file "/var/run/dhcp/db.168.192.in-addr.arpa";
 update-policy {
   grant local-ddns zonesub any;
 };
};’


and then I do “nsupdate -l -v -4 my-update-file-here”

But I see 125 instances of “update failed: REFUSED” which incidentally is the 
number of PTR records.

Lastly, if I query a local host A record that works.  But when I query that 
address for a PTR record it fails.

So… why am I authoritative for “redfish-solutions.com 
<http://redfish-solutions.com/>” but not for “168.192.in-addr.arpa”?

The top of my dhcpd.conf file looks like:

authoritative;
ddns-domainname "redfish-solutions.com.";
ddns-update-style standard;
ddns-updates on;
ignore client-updates;

update-static-leases on;
use-host-decl-names on;
update-conflict-detection off;
update-optimization off;

include "/var/run/named/session.key";

zone redfish-solutions.com. {
 primary 127.0.0.1;
 key local-ddns;
}

zone 168.192.in-addr.arpa. {
 primary 127.0.0.1;
 key local-ddns;
}


My named.conf file contains:

options {
   …
   // This is used e.g. by isc-dhcp
   allow-new-zones yes;
   …
};



It’s probably something simple but at this point I can’t see the forest for the 
trees…. Please help me get a patch out the door quickly.

Thanks
