[Pdns-users] Explicit Notification (from the users pov)

[Markus Lauer]

Hi List!

I'm experimenting with a chain of hidden masters.


PDNS (hidden master)   --NOTIFY-->   OPENDNSSEC (hidden master)   --NOTIFY--> 
PUBLIC PRIMARY

(AXFRs the other way round)


Problem is: PDNS notifies only hosts it finds in the NS records of the changed 
zone. I don't know how to loop-in a second hidden master. In BIND there's a 
configuration option for this:

options {
    also-notify { [opendnssecip]; }; // all zones
    notify explicit;
};

(See http://www.zytrax.com/books/dns/ch7/xfer.html#notify)

You can achieve a similar behaviour with PDNS by calling "pdns_control notify-
host" (http://doc.powerdns.com/master.html). This ignores the NS records from 
zone and only notifies the explicit IP.

Is there a way to get automatic explicit notifies?
I send the same mail to pdns-dev with an rough idea on how to change pdns to 
allow explicit notifies. But maybe someone here in pdns-users has an idea for 
an alternative setup.

Please see also the blog entry from Jan-Piet Mens:

for-signing-zones/
