LINUX, CPANEL & WHM

Hi Guys,
I'm a systems admin for a small company and we are a Windows shop.
A software developer requested a Linux VM, with CPANEL & WHM.

I have never used CPANEL before.

The request came from high up and I just finish the installation.
I have the root admin access using WHM, and I have created a CPANEL Admin access for the Software Developer.

When I log in to the CPANEL with the Software Developer user I found quite the arrange of options to make changes. I don't really care about the Linux VM itself and it is only running that for him, but ...

I did setup the Linux VM to use my Windows Domain DNS Servers.
And when the CPANEL installation process asked about the domain name I used the same Windows Domain.

My questions:

Can the Software Developer damage, or change my Windows DNS Servers or my Windows Domain using CPANEL????

Should I change the DNS Servers and Domain in the WHM & CPANEL?


Thanking you in advance,
Cargex

No, they can not change anything on your windows domains. That is just for pointing DNS to the appropriate server.  You have two options (with variation). CPanel can point to itself and run DNS for said domain, or you can specify non-local DNS servers to query.
Other than possibly setting a rDNS when handed a DHCP address, the *nix box can't change your Win DNS.

Hi Mugojava,
I like the option of making it point to itself.
Can you please give me some pointers as to how to do that?

Classically, if you point to yourself, CPanel expects you are running an authoritative name server.  If your cpanel install runs your DNS for said domains it's hosting, this also requires that:

1. You register the new DNS servers with the registrar so that the public can find them.
2. Your bind (DNS server)  install Cpanel is using is available to the public
3. You change the authoritative name servers at the registrar to point to your new cpanel server's DNS server.


Something tells me that's not what you are looking for. True?

You are correct.
This is a server for development purposes only, so I don't need DNS Servers hosting domains that can be access by the public.

So let's see if I understand.
The CPANEL installation process should have installed DNS Service on the Linux VM, and now I could use it in the CPANEL / WHM Configuration?

For development, where all DNS is already establishes on servers, basically, you won't be using the Cpanel DNS server (called "Bind"), but you will be using the DNS Client, should the machine need to look up some domain. The DNS servers you want to use on your local nework would be under the network settings in cPanel...I don't have in install here handy, so not sure where to point you to, but on the machine, the name servers it should use are in /etc/resolv.conf

For Cpanel to serve a domain, all you have to do is set that web site up, naming the domain, then from wherever you are hosing your DNS for said domain, change or add the appropriate A records to point to that box.

Basically, you can disregard the DNS server, set up the site (ignore any DNS settings) on Cpanel, then point your DNS A records, if needed, to it. I'm not sure of the naming convention you are using, if you are using a full domain, or just like "production5", etc. So, a little foggy on what to tell you there.
