Re: [webmin-l] Cluster DNS

Jamie,
I am stuck in a not too bad-a-place right now. Here is what I am seeing:
When I add a forward zone, and click "Apply Changes" from within the =
"Edit Master Zone" beleive it or not, the zone becomes active on both =
servers.
No reverse is added automaticaly.
I add the reverse to the arpa zone and click the "Apply Changes" and the =
new reverse becomes active on both.
When I delete the forward, I am presented with a screen that asks me if =
I want to Delete the Reverse (I say yes) and Delete from Slave (I say =
yes), and hit Delete, it takes out the zone, arpa antry, and config from =
master and slave. Then when I go back to the mainpage and hit apply, =
both master and slave are HUPed.
So again, the only real 'problem' I see is that the arpa entry is not =
being added when a forward zone is added. <--- any ideas?
As for the Forward and Reverse needing to be applied, I havent got far =
enough to see that problem. But would'nt a HUP solve that?

One 'bug' in Webmin at the moment is that when you add a record to a =
forward zone which triggers the addition of a corresponding record to =
reverse zone, both zones need to be applied for the change to fully take =
effect. If you only click Apply in the forward zone, BIND will not =
reload the reverse zone.
I am still working out a way to properly fix this ..

Yes, when I update a Zone, I use the update button. When I add a =
zone I use the apply changes button.

So the zone transfer is not bringing in new records?! That is odd =
..
Are you always using the Apply Changes button on the module's main =
page after making any record changes?

Jamie,
After many millions more milliseconds of testing, here is the =
sum of what I see happening:
When a new (forward) zone is added, a reverse record is not =
being added, either on the master or slave.
If I add the reverse, let both nameservers update, then delete =
the forward, it WILL remove the reverse record.
So, any ideas why it will automaticly remove a reverse record, =
but not add one?

Webmin can do automatic reverse DNS entries in non-class-C =
zones now .. it has been improved a lot since the book was written :-)
If your ISP delegates blocks smaller than a class C and you =
have to use that PTR record trick for your reverse records, Webmin will =
not automatically update them..

Thanks for the reply Jamie.
I was reading in your book about reverse DNS updating not =
being available to non class C blocks. Is this still true?
My ISP does delegate me blocks, usually 126 at a time. when =
I add a forward zone, should my arpa zones be able to be updated?

Hi Grant,
You need to click the Apply Changes button at the bottom =
of the main page in the BIND module after adding zone. In a cluster =
setup, this will restart both the master and slave servers, and so =
should trigger the transfer of both forward and reverse zones..

Hi (again) all,
I *think* I have a grip on what is, and is not happening =
here. ANyt helpo would be aprreciated.
When adding a new zone on the master server, through =
webmin,
Q: The (FORWARD) zone is added and configured, and =
the named.conf change IS sent to the slave, but, the zone is not being =
made active on the slave. Is this normal?
If not any ideas how to fix?
The reverse zone is not being updated at all on the =
master or slave. (yes, the update reverse is ON by default).
Q: Any ideas how to fix?
When deleting a zone:
The (forward) zone does get deleted from the master =
and the slave.
The reverse does get removed from the master, and =
the serial number is inc'd. The reverse is not done right away on the =
slave, but I suspect the refresh will update it in an hour.
If I add or delete a reverse record and click the apply =
button, it DOES apply to both the Master and Slave.

Hi all,
I have spent a lot of time getting the Bind8 DNS =
modules to work (cluster) on my master and slave server.
THe only question (I think!) that I have now is:
When I add/update/delete a zone on the master =
server, how to configure the master to tell the slave to reconfig or =
reload the zone?
(The slave named.conf is being updated, but the =
changes are not being made active automaticaly).
