Remove Redundant DCs internal DNS
Hello List,
I have successfully migrated my DCs to 4.7.6-Ubuntu
However, I still have some traces of the old DCs in the DNS...
$ samba-tool dns query dc3 mydomain.com @ ALL
Name=, Records=8, Children=0
SOA: serial=570, refresh=900, retry=600, expire=86400, minttl=0, ns=dc3.mydomain.com.
NS: samba.mydomain.com. (flags=600000f0, serial=110, ttl=900)
NS: dc3.mydomain.com.

Sorry Paully,
I thought i already replied it. The configs look good.
Did a look back in time.. And Ahh.. Now this i missed.
* yesterday, we changed the IP addresses of our DCs and the Wiki page did not mention (IMHO) 2 critical things...
...
So you even missed more.
Review all DNS entries for the problem DC and review your AD again.
rgrep /etc and /var for all the old ip numbers and/or

Hello Samba List,
I have 2 problems with dns - seeing the child entries and a zone with an extra octet.

AD DCs Upgrade
I am planning to upgrade the DCs using the join and promote method.
List of DCs

Currently SAMBA1 is the PDC and SAMBA2 is the "SDC" and are in sync with replication and rsync sysvol. DCs SAMBA1 and SAMBA2 are 4.1 git releases with AD Schema version 47.
My plan to get to AD Schema version 69 was...

Guys, what i noticed.
Look at this.
Refused- 1/3/0 (Class 254) ( /24 )
Paully used /16
update 1/3/1 (Class 254) CNAME V-RDS02.mydomain.com
CNAME ?
And, if he uses in his example
samba-tool dns add dc3 mydomain.com V-RDS02 A 130.130.0.252
A record was used.
Is resolv.conf checked and it is sure in pointing to the correct DNS of the AD first?

Failover DC did not work when Main DC failed
My reverse zones have PTR records. Though I don't have NS records for all
of my DC's. I guess that needs to be manually created.
Also, you don't have any CNAMES or domain overrides pointing to a single
DC? Perhaps Bind is pointing to another internal DNS server, and then to a
public DNS?

Here's a way to test failover from a Windows client:
You can switch logon servers

Connected, but what now?
Hi
Gavin and I appear to have successfully connected our Linux and Windows machines via Tinc, but cannot seem to do anything else.
We cannot ping each other's vpn network.
Gavin would like to be able to:
* browse my local SMB (Windows and Samba) network
* collect his email via my local mail server
Are asking too much of a VPN here? Have we missed something?
All details, Linux output and
