Hello,
I try to set up a ADDC with bind9 and dhcp-Server for dynamic
DNS-updates. I followd the wiki:
https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_wi
th_BIND9
My problem is, that the PTR Record will not be updated, because the
script is using the wrong reverse-zone:
- ---------------------
Dez 26 17:30:05 addc-01 named[512]: client 192.168.56.200#60564/key
dhcpduser\@EXAMPLE.NET: updating zone '168.192.IN-ADDR.ARPA/IN':
update failed: not authoritative for update zone (NOTAUTH)
Dez 26 17:30:05 addc-01 logger[989]: DHCP-DNS Update failed: 02
Dez 26 17:30:05 addc-01 dhcpd[803]: execute:
/etc/dhcp/bin/dhcp-dyndns.sh exit status 512
- ---------------------
The zonename should be "56.168.192.in-addr.arpa" so the "56" is missing.
The forward-zone works.
My reverse-zone is:
- --------------------
root at addc-01:~# samba-tool dns zonelist addc-01
3 zone(s) found
pszZoneName : 56.168.192.in-addr.arpa
Flags : DNS_RPC_ZONE_DSINTEGRATED
DNS_RPC_ZONE_UPDATE_SECURE
ZoneType : DNS_ZONE_TYPE_PRIMARY
Version : 50
dwDpFlags : DNS_DP_AUTOCREATED
DNS_DP_DOMAIN_DEFAULT DNS_DP_ENLISTED
pszDpFqdn : DomainDnsZones.example.net
- --------------------
My dhcpd.conf is a copy from the wiki with my values:
- -------------------
subnet 192.168.56.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.56.255;
option time-offset 0;
option routers 192.168.56.1;
option domain-name "example.net";
option domain-name-servers 192.168.56.200;
option netbios-name-servers 192.168.56.200;
option ntp-servers 192.168.0.200;
pool {
max-lease-time 1800; # 30 minutes
range 192.168.56.210 192.168.56.229;
}
- -------------------
So where do I have to set up the right reverse-zone?
