Has anyone found how to make kea-ddns work with PowerDNS? pdns logs
suggest:
pdns[20989]: UPDATE (50855) from 10.10.1.254 for lan.: Failed
PreRequisites check, returning 6
The query log shows only some normal SELECT statements. If it's not a
known problem can anyone show how to find what the DNS UPDATE command
is
being sent to the DNS server to diagnose?
Someone else had problem but couldn't get resolution:
https://github.com/PowerDNS/pdns/issues/5830
Problem seems to be using TSIG signed DNSUPDATE requests. There used to
be a Kea bug
http://kea.isc.org/ticket/5071#ticket
But the link is dead. Is that bug fixed? Is the problem with Kea or
maybe the older version of powerDNS?
Question - after I removed TSIG the initial forward and reverse
DNSUPDATE commands succeed:
DHCP_DDNS_ADD_SUCCEEDED DHCP_DDNS Request ID xxx: successfully added the
DNS mapping addition for this request: Type: 0 (CHG_ADD)
But Kea does another CHG_ADD only a minute later and it fails:
DHCP_DDNS_FORWARD_REPLACE_REJECTED DNS Request ID yyy: Server,
10.10.1.254 port:5353, rejected a DNS update request to replace the
address mapping for FQDN, wkst4.lan., with an RCODE: 8
DHCP_DDNS_ADD_FAILED DHCP_DDNS Request ID yyy: Transaction outcome
Status: Failed, Event: UPDATE_FAILED_EVT, Forward change: failed,
Reverse change: failed, request: Type: 0 (CHG_ADD)
Is this a problem or can it be ignored? Is it due to setting
"override-no-update": true and "override-client-update": true?
