[Samba] DNS IPv6 Question

[Ulrich Schinz]

Hi there,

Domaincontroller name: risky.home.schinz.de


dig dig @risky -tANY risky.home.schinz.de.

returns:

;; ANSWER SECTION:
risky.home.schinz.de.    900    IN    A    10.0.180.254
risky.home.schinz.de.    900    IN    AAAA    ::1

I have a strange behavior in my network. It's only concerning DNS, but 
maybe someone can help me.

If a do a ssh on risky from another machine (exact command: ssh 
root at risky, having domain/search set in resolv.conf) results in a 
loginattempt on localhost. But "host risky" returns 10.0.180.254.

First workaround was to update my /etc/hosts... But it's not a valid 
solution in my opinion. So I researched a little and used dig for that. 
There I found the above entry in DNS.

I'm not familiar with ipv6, but I think that ::1 is a shorthand for ipv6 
version of 127.0.0.1, i.e. localhost. So I concluded, that my ssh 
connect attempt returns a ipv6 entry, which points to localhost....

So now i tried to update/remove that ipv6 entry, but I always get the 
error: ERROR: Record does not exist

I tried these:

samba-tool dns delete risky.home.schinz.de home.schinz.de risky AAAA 
0:0:0:0:0:0:0:1 -UAdministrator
samba-tool dns delete risky.home.schinz.de home.schinz.de 
risky.home.schinz.de. AAAA 0:0:0:0:0:0:0:1 -UAdministrator
samba-tool dns delete risky.home.schinz.de home.schinz.de risky AAAA ::1 
-UAdministrator
....

same procedure with samba-tool dns update ....

How must be the syntax to get rid of this ipv6-dnsrecord or to get it 
updated to the right adress of eth0?

Another question is: Is this a good idea? I hope AD does not need this 
dnsrecord....

Kind regards
Uli
