HOW:~ Own Name Servers (DNS)

[ServerIntelligence]

Hi All.
Just had Cpanel installed on one of my servers and not knowing a lot about it. I need to find out how to setup my own nameservers.

I have on setup added the nameservers details to primary & secondary parts in WHM as ns1 & ns2 etc. But how do I attach the IP's to them?

Can someone explain how to do it from start to finish or post a how to please.

Kind regards,

Brian

Go to &Manage Nameservers& in WHM and you'll see the IP associated with each NS..

Ok.

I see the following:~


Updating records for ip 64.XX.XXX.X52..... Done
IP Nameserver
64.XX.XX.X50 ns1.XXXXXX.com Red X
64.XX.XX.X51 ns2.XXXXXX.com Red X
64.XX.XX.X53 64.XX.XX.X53 Red X
64.XX.XX.X54 64.XX.XX.X54 Red X

The main server IP is 64.XX.XX.X50 and its being used for NS1. IP 64.XX.XX.X51 is using the NS2 NS.

I did not want the main server IP being used and need the 2 spare IP's of 64.XX.XX.X53 & X54 to be used for NS1 & NS2.

How can I change it over or is it ok to use the main IP issued for one of the NS1 and another spare IP for NS2.

Thanks,

Brian

PS.

Hope this makes any sence.

Always best to think of your two lowest IP's as the two to be used for Nameservers -- for that Server. Entries shown for .53 & .54 are incorrect and should be removed. You can do this be manually editting [b:1feccc7354]# /etc/nameserverips[/b:1feccc7354] and removing them -- should say: =0 not the IP address. This will put those two IP's back into availability status. File is [readonly] BTW so you need to change it then change it back when finished.

I have deleted the 2 IP's from the # /etc/nameserverips file and made them =0

When I go back into Manage Nameserver IPs in WHM it still shows them as before?

Any ideas?

I would use: WHM & Ip Functions & Rebuild the IP Address Pool
or just Restart Bind.

Thanks, I'll try it now.

I edited the nameserverips file but the IP's keep on returning. What is the command so I can find out what the chmod is for the file so I can edited it.

Ahh, you re-read my earlier post I see.

The file is 444 (or -r--r--r--) by defualt so you need to first:

# chmod 755 /etc/nameserverips

# vi /etc/nameserverips

make changes and save

# chmod 444 /etc/nameserverips


I'm suprized though, because if you use Vi and when you first opened the file, it would have stated at the bottom it was a readonly file. Handy thing that is.

Well I chmod 755 /etc/nameserverips edited the file using Pico to read the following:

64.XXX.XX.X50=ns1.serverintelligence.com
64.XXX.XX.X51=ns2.serverintelligence.com
64.XXX.XX.X52=0
64.XXX.XX.X53=0
64.XXX.XX.X54=0

Then chmod 444 /etc/nameserverips and run Rebuild the IP Address Pool.

It still stated the 2 IP's with in Manage Nameserver IPs and I went back into /etc/nameserverips file and they were put back in?


Now Im lost?????

Hey, Website_Rob,
Is it possible for me to edit the file and put say:

12.345.67.8 ns1.mydomain.com
12.345.67.9 ns2.mydomain.com
12.345.67.8 ns1.otherdomain.com
12.345.67.9 ns2.otherdomain.com

Or will that cause problems?

Don't forget the equal sign and I wouldn't use the same IP for two different host names. There is lots I don't know about DNS, but using the same IP for two different host names is not something I am familiar with.

Something I forgot to mention in my earlier posts is that the nameserverips file may also be readonly. As I use Vi (I used to use Pico) it tells me whenever the file is read only. So, if, after making changes you re-open the file and nothing has changed, you know the file is readonly.

chattr -i allows changes to be made

chattr +i makes the file readonly
