Hello, I need an advice about DNS implementation. I wonder can I plan the situation like this: I have 10 Virtualmin GPL servers (with dns service) and 2 DNS servers (Name servers) with webmin installed. Can I make these 2 Name servers act as primary Name servers and let them synchronize with virtualmin servers. For example my client connects to Virtualmin server, then create DNS entry, after some time this entry synchronizes with 2 Name servers?
The second question is about possible DNS conflict. I allow my customers to edit their DNS entries. Then I create an entry 92.61.41.69 www.aaa.com for my customer "A". Then, after some time another client "B" just playing with a system and edit its zone to 92.61.45.59 www.aaa.com (domain aaa.com does not belong to him it is property of customer "A"). Will a system does have conflict?
you can have only one nameserver to be authorative.
the master dns should be on the virtualmin system though, one of the slave servers can be authorative, whereas the other is just a slave.
Ronald, thanks for the reply. Actually my skills in DNS area are not very strong, I need more clearness. So I can have 10 master dns servers with virtualmin, wich can replicate to a single authorative server. And this authorative server also can have one or more slave servers (with webmin installed) and send them replicas? Is this method actually good in various aspects? I won't have the problems later?
Maybe someone could answer my initial post a second part question about a worry of system confilct?
Could someone answer this question, please?

In the case that you're describing, customer B should not be able to make DNS edits to aaa.com since they don't own the domain.
Using Virtualmin, when you give a user the ability to edit DNS, a given user can only make changes to domains they own.

Thank you.
What do you think about first part of my initial post? I just need to know a way how can I synchronize all virtualmin servers DNS service with 2 my nameservers with webmin. I just don't want separate hosting and domain management.
One method that I was thinking about is to provide DNS service in every virtualmin server and then implement DNS backup through backup scheduler (Records in DNS domain, except SOA ) to the remote computer (Name server) and restore them regulary several times per day?
Is it possible? Any alternatives.
