DNS in a 2nd non cpanel server

cPanel has the option just to install DNS only, you can see for yourself here: http://layer1.cpanel.net/

Here are some installation commands that should work. I simply adapted the main installation to the one needed to just install DNS Only:

Code:

mkdir /home/cpdnsonlyins
cd /home/cpdnsonlyins
wget http://layer1.cpanel.net/cpanel-universal-dnsonly-install.sea
sh cpanel-universal-dnsonly-install.sea

 

Your going to have to install BIND on its own then, i think this is the website: http://www.isc.org/index.pl?/sw/bind/

 

As far as I can tell, the "nameserver only" version of cPanel does not require licencing. However, it will only act as a "slave" nameserver - it does not have account creation, dns zone creation/modification etc etc.

 

Indeed, it is free and as richy says, it is quite limited, but it does provide you with a slave DNS which automatically updates. Otherwise, you'll just have to go the traditional route with a DNS master/slave setup where you have to manually create the zone entries in named.conf on the slave, unless you do some scripting to copy over the master and reconfigure it as a slave.

 

There's no need to rsync the zone files as DNS will do that as part of a normal master/slave relationship (you should read up on how to set that up if you don't know - google is your friend there). The manual part, as I mentioned would be to add the actual zone entries to /etc/named.conf. You cannot simply just copy over a named.conf from the master to the slave, as you'll see when you check how to setup a master/slave nameserver relationship.

 

A lot depends on who controls the DNS entries. Since handling DNS in cPanel is so simple, if you have two DNS servers in separate NOCs, I'd be tempted to just cluster those two to handle all the DNS zones for all the domains on all servers.

 

ns1 points to one server, ns2 points to a different server, then cluster them and select the options to sync all zones between both servers.

 

Hi,

1. I think that you may have to do that from the normal cPanel server, but I don't recall

2. You have a WHM login on the DNS ONLY version with much reduced functionality

3. Yes, you would need to change the IP addresses at your registrar for your nameservers pointing on to one servers IP and the other to the others servers IP. You would also need to update the zone file for the domain that the ns1/ns2 A records are on to point to the correct IP addresses

4. Yes, if either nameserver becomes unavailable the other will be available to server DNS requests for your domains

 

I do not know where the script is to generate the hash from DNS Only, none of my servers have that installed... but i have a suggestion.

The access hash is stored here:

Code:

 /root/.accesshash 

See if a code has already been generated

 

On the server run:

netstat -lpn

Ports 2086 and 2087 should be bound. If only 2086 is, then try connecting to the non-SSL port http://ip:2086

If neither are bound, there's a problem

If either are bound but you cannot connect, you probably have a firewall running:

/etc/init.d/iptables stop

then try accessing again/

 

My company is small ISP that has one DNS server, and I am trying to place our DNS as the master nameserver, ns2.domain.com as primary nameserver, and ns1.domain.name as secondary (or something else, I don't know what to put there). When I do this, Assign IP for primary or secondary ns gives me internal IP or one of added IPs. Now, how do I configure this?

 

Currently I have a typical master/slave zone transfer configuration which works fine.

There are 2 DNS servers running on 2 separate systems

Server 1: Cpanel master DNS
Server 2: Windows Bind slave DNS

Server 2 (Windows) automatically updates its zones that are located in d:\dns\etc\named.conf with any changes that were made on server 2 (Cpanel).

However, the zones must exist in d:\dns\etc\named.conf on server 2 (Windows) for it to be updated by the data on server 1 (Cpanel).

For Example:
When I create a new cpanel account on server 1, a new zone is created automatically in /etc/named.conf on the Cpanel server.

If I want this zone to be added to server 2 (Windows) and I must first manually add the slave zone in d:\dns\etc\named.conf on server 2 (Windows).

Then server 1 will keep the zones on server 2 up to date with any changes I make in Cpanel.

This works great but I first need to manually modify named.conf on the Windows server every time I create a new Cpanel Account.

I have read many posts both here and elsewhere pertaining to bind and I cannot seem to find a solid solution.

I noticed that Cpanel has a DNS only release that allows you to do this automatically; however, I need server 2 to stay as a Windows system.

Is there a way to configure Bind to make automatically changes in named.conf
on the slave system?

Others have suggested using scripts to perform these tasks but I could not locate any for my particula situation.

There are a lot of posts pertaining to this issue of configuring a secondary redundant DNS server. I was hoping someone here has ran into the same problem and could offer their wisdom on how they overcame it?

Thanks
