Hello Samba List,
I have 2 problems with dns - seeing the child entries and a zone with an extra octet.
First...
I have created a /16 reverse zone as per the wiki page (https://wiki.samba.org/index.php/DNS_Administration#To_create_a_.2F24_reverse_zone)...
$ samba-tool dns zonecreate dc3 130.130.in-addr.arpa
$ samba-tool dns zonelist --reverse dc3
pszZoneName : 130.130.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.mydomain.com
$ samba-tool dns add dc3 130.130.in-addr.arpa 218.0 PTR dc3.mydomain.com
$ samba-tool dns add dc3 130.130.in-addr.arpa 219.0 PTR dc4.mydomain.com
$ samba-tool dns add dc3 130.130.in-addr.arpa 201.0 PTR server2.mydomain.com
etc
$ samba-tool dns query dc3 130.130.in-addr.arpa @ ALL
Name=, Records=3, Children=0
SOA: serial=32, refresh=900, retry=600, expire=86400, minttl=3600, ns=dc3.mydomain.com., email=hostmaster.mydomain.com. (flags=600000f0, serial=32, ttl=3600)
NS: dc3.mydomain.com. (flags=600000f0, serial=1, ttl=3600)
NS: dc4.mydomain.com. (flags=600000f0, serial=2, ttl=900)
Name=0, Records=0, Children=15
How do I see the 'Children=15' entries using the samba-tool on the command line?
Next...
When this /16 reverse zone is viewed in the Windows DNS Manager GUI an extra octet appears in the IP address range and 3 question marks appear in a dialog box.
Name Type Data
130.130.0.0.218 Pointer (PTR) dc3.mydomain.com
Fully qualified domain name (FQDN):
???.in-addr.arpa
Host name:
dc3.mydomain.com
