Clearly not. Removing the unwanted 'A 192.168.216.162' resource record worked
the first time. It probably was a mistake on my part to do so but, it worked.
What is left is the NS artifact of the first join of smb4-2.
Name=, Records=4, Children=0
SOA: serial=19, refresh=900, retry=600, expire=86400, minttl=3600,
(flags=600000f0, serial=19, ttl=3600)
NS: SMB4-1.brockley.harte-lyne.ca. (flags=600000f0, serial=110, ttl=900)
A: 192.168.18.161 (flags=600000f0, serial=110, ttl=900)
A: 192.168.216.162 (flags=600000f0, serial=110, ttl=900)
An A record entry would look like this:
Name=smb4-2, Records=1, Children=0
A: 192.168.216.162 (flags=f0, serial=110, ttl=900)
But there is none.
In a BIND hosts file the name service header given above would look like this:
;IN SOA hostname email serial refresh retry expire TTL
SMB4-1.brockley.harte-lyne.ca. IN SOA brockley.harte-lyne.ca.
;# Registered Name Servers
IN NS 192.168.18.161
IN NS 192.168.216.162
In this set up all I need do is delete the line 'IN NS 192.168.216.162',
change the serial number (19=>20), and rndc reload.
I am finding it difficult to understand why making this trivial change is so
convoluted in Samba. I thought that my use of the syntax for samba-tool dns
delete was correct but it could not find an NS record with the argument
192.168.216.162. And yet one clearly exists.
Of course, now I have other problems stemming from my awkward attempts to solve
