samba - Oct 2019 - Changing the A-Record of the domain.

Hi,

after installing a samba-4.8.9 AD-Server there is/are an A-Records
created for the domain delivering the ip-address(es) of the AD-server.
This ip can be changed vie "samba-tool dns update" but after
restarting
the AD-server the ip-address of the server will be added again.
Can this be prohibited or is this necessary to the functionality of the
 AD-server.

Thanks!

Why do you need to change the IP ?

If an IP is being added after Samba is restarted, this is obviously 
being done by samba_dnsupdate, which is adding the ipaddress of the DC 
and this is required.

This sounds all correct, but im betting your having multiple interfaces and the
default is off.

Can you shown. 

hostname -s
hostname -d
hostname -f
hostname -I
hostname -A

And 
dig -x wanted_ip
Dig -x current-Ip. 

cat /etc/resolv.conf
cat /etc/hosts

And you OS is?

That was my thought, which is why I asked why the IP needed changing, I 
think the OP also needs to post their smb.conf.

This system was migrated form samba-3 NT to samba-4 AD. The A-Record of
the DNS-Domain pointed to the web-server which is placed on an other
server.

Thanks that was what I wanted to know. There are some rules in life
that you have to accept. That's one of those :-)
