DDNS updates with primary and secondary server

[Andre Schubert]

Hi all,

iam playing a little bit with ISC dhcp-3.0.1 and dhcp-3.0.5 and DDNS updates.
These are the snippets from my config:

    key DHCP_UPDATER {
         algorithm hmac-md5;
         secret "<SECRET>";
    };

    zone cpes.local. {
         primary 127.0.0.1;
         secondary 10.0.0.2;
         key DHCP_UPDATER;
    }

DDNS updates to the primary works perfectly.
But when the primary goes down, then the secondary isnt used anymore and
dhcpd logs a time out.
I also see no packets with a packet sniffer going to 10.0.0.2:53.

>From the docs in dns.c i read, that the DDNS updates should be performed on
the secondaries if the primary timed out.
Iam doing something wrong?
Or does this not really work with these versions?

Best regards,
Andre Schubert
