samba - Feb 2019 - Samba + BIND9 DLZ. DNS dosen't resolve FQDN, only short hostname

Rowland, thank You, but this removes only the NS record, but the faulty
domain A records remain. How to deal with them, I don't know. They
behave unlike the ordinary A records.

Name=, Records=8, Children=0
    SOA: serial=27, refresh=900, retry=600, expire=86400, minttl=3600,
ns=blacktux.interbronz.local., email=hostmaster.interbronz.local.
(flags=600000f0, serial=27, ttl=3600)
    NS: blacktux.interbronz.local. (flags=600000f0, serial=1, ttl=900)
    A: 10.10.10.101 (flags=600000f0, serial=1, ttl=900)
    A: 10.20.1.1 (flags=600000f0, serial=3, ttl=900)
    A: 10.20.2.1 (flags=600000f0, serial=9, ttl=900)
    A: 10.20.3.1 (flags=600000f0, serial=10, ttl=900)
    A: 10.20.4.1 (flags=600000f0, serial=11, ttl=900)
    A: 10.30.1.1 (flags=600000f0, serial=23, ttl=900)

You posted:

I can manage standard A records, but not sure, what to do with the NS. I 
can't figure out, how to delete invalid A subrecord of NS record.

So I took it you wanted to know how to remove an NS record.

You remove an 'A' record in a similar way, try reading:

'samba-tool dns samba-tool dns delete --help'

Which will produce this:

Usage: samba-tool dns delete <server> <zone> <name>
<A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>

Delete a DNS record

For each type data contents are as follows:
  A      ipv4_address_string
  AAAA   ipv6_address_string
  PTR    fqdn_string
  CNAME  fqdn_string
  NS     fqdn_string
  MX     "fqdn_string preference"
  SRV    "fqdn_string port priority weight"
  TXT    "'string1' 'string2' ..."

See if you can work out how to delete the unwanted 'A' records ?

Rowland

Well, I gone so far even before :-) I even deleted them with "Records 
deleted successfully", but listing the domain records, they were still 
there. That's why I thought I must have wrong syntax or so.

But looking at the record again now, they are gone. That's good.

However, that dosen't help resolve the FQDN issue.


So, next thing I will probably do, according to Your advice, is to try 
installing newer version of Samba.

I doubt it will help though, cause I doubt the 4.5 version was such 
flawed that the basic DNS function didn't work because of that.

Well, I have finally installed Samba 4.9 from Van Belle's repo, but 
still I cannot resolve FQDN's.
