I have set up Samba 4.12.14-Deb on Jessie as a member server for my AD and (so far) everything works fine. This machine does have a few Tun* Interfaces for openVPN tunnels (which are also working fine). Samba has to listen on those and it does perfectly (thanks to the interfaces setting in smb.conf).
Now, after every reboot, samba (I assume) registers alle the IP adresses listed in smb.conf as dynmic A records in my AD DNS. As good as this concept is, this causes a lot of trouble here, obviously. In Windows I can just uncheck the 'register this connection in DNS' option.
How do I prevent Samba (or whoever does this) from registering "all the adresses"?
Or, if that's not possible, how do I prevent it from registering itself in my DNS at all? In my case, a static (non-changing) entry would be more helpful than all the tunadresses.
I actually wanted to get the answer from here, but couldn't ask if you have solved it, so here is the solution which works with at least samba 4.11
The interfaces parameter actually also understands IPs and Subnets, so you can put there all the ips that are necessary to be registered. You can then also use
to limit samba to listen to those IPs or to listen on 0.0.0.0
In your case, where there are tunnels on the devices, due to the weak network model of linux any traffic destined for 10.1.1.1 on any interface would be forwarded correctly.
