#2618 Stub Zones & Clusters
Using the "clustered name server" feature & a stub
zone is created for reverse lookups. the reverse
lookups work correctly on the primary server. the
records are not created correctly on the other
servers in the named.conf and also in the supporting
files .rev and such.
Just stumbled across this so i have not done a
complete test yet. We were planning on using webmin
to manage the 3 internal dns servers. For us, these 3
will replace direct internic lookup for the 50 odd
internal zones so its important that they work right.
basically replacing the root hints on all internal
dns servers across the wan to point to these 3
internal lookup servers.
let me know if i can do anything to aid in this
problem getting fixed.

When you setup a slave DNS server like that, Webmin
configures it to be DNS slave of the master. This means that
the transfer of records is done by BIND rather than by
Webmin, usually on a regular schedule set according to the
SOA record (called Zone Parameters in Webmin).
To force a transfer, login to Webmin on the slave, go to the
BIND module and click on the restart button. If this doesn't
work, check the log file /var/log/messages on the slave to
see if anything is logged saying why the transfer failed.

i was creating stub zones... it should create a stub zone
on all slaves just like was created on the master server.
I thougth the point of a cluster was to have all servers
with exactly the same data?
I found a way around the problem... i am using the cluster
file copy function in webmin as a work around.
stop named
copy /var/named/chroot/etc; /var/named/chroot/var
start named
with a repeat every 15 mins (for now it will be every 1 hr
in a week or so)
i do the same thing for all dns servers so they all end up
exactly the same... it seems to work...
perhaps i am mis-using each function. our goal is to have
a sort of private internic until we can consolidate all
active directorys down... so we will have local site dns
with root hints that point to our private internic. the
private internic servers will/should resolve anything for
any address is already knows locally and search the real
internic when they do not contain data for local zones.
our global wan will at its start contain very few sites
40+ with in a few short months we will have over 300+ so i
was looking for a way to "glue" all the local DNS servers
together internally.

The aim of the cluster feature is to create master zones on
a master server, and corresponding slave zones on other
servers that replicate from the master.
However, it is possible to do what you want too. When adding
a slave on the 'Cluster Slave Servers' page, you need to set
the 'Create secondary on slave when creating locally?' to
'Yes'.

Now I understand this feature... I think we will just
continue to use the file copy function. I get 3 masters
exactly the same. Not how its done normally, but it seems
to be working. I have about 20 forward & reverse zones
created so far and they all seem solid. I really should be
doing this with some database, closer to how internic
really does it, but who has time for all that!
Thanks for your help!
Medeco & Assa Abloy love webmin as a whole and will
continue to use its many features to make administration a
breeze!

Just copying the files would work fine too..
I'll consider this bug closed then.
