ISC-DHCP and PowerDNS for DDNS "Unable to add forward map <FQDN> to <IP>:unexpected error


I have trouble implementing isc-dhcp with powerdns for ddns, no matter how many time i've change to configuration, it will always came back with this error "Unable to add forward map from to : operation canceled"

then this "Unable to add forward map from to : unexpected error"

this is my dhcpd.conf file

authoritative;
log-facility local7;

key dhcp-key {
        algorithm hmac-sha256;
        secret "some comfusing scramble alphabet and number and symbol ass well";
};

max-lease-time 2160000;

ddns-rev-domainname "in-addr.arpa.";

zone gwusers.lan. {
        primary 192.168.183.111;
        key dhcp-key;
}

shared-network user-ip {
        subnet 172.17.183.0 netmask 255.255.255.0 {
                option routers 172.17.183.254;
                option domain-name-servers 192.168.183.111, 192.168.183.222;
                option domain-search "mycomp.local";

                pool {
                        #one-lease-per-client true;
                        ping-check true;
                        range 172.17.183.1 172.17.183.229;
                }
                zone 183.17.172.in-addr.arpa. {
                        primary 192.168.183.111;
                        key dhcp-key;
                }
        }

        subnet 172.21.183.0 netmask 255.255.255.0 {

                option domain-search "mycomp.local";

                pool {
                        #one-lease-per-client true;
                        ping-check true;
                        range 172.21.183.1 172.21.183.229;
                }

                zone 183.21.172.in-addr.arpa. {
                       primary 192.168.183.111;
                       key dhcp-key;
               }
        }
}

on my pdns.conf

i have enable "dnsupdate=yes" and "allow-dnsupdate-from="

i have follow this guide but doesn't seem to work at all

NB : dhcp-server (Centos 8 with dhcpd version is 4.3.6) and dns server (centos 7 with pdns version is 4.3.0) is not under 1 machine, i have installed them separately.

does anybody know how to fix this?


Solution

  • Ok, i found solution myself, so i'm gonna answer this, turns out my powerdns authoritative server run under different port because i run powerdns-recursor under the same machine as powerdns authoritative. so the solution is add another NIC and assign another ip to that new NIC and problem solved.
