    A Beginner's Guide to Name Servers Part-1 (Setting up nameservers in WHM/Cpanel)

    A Beginner's Guide to Name Servers Part-1 (Setting up nameservers in WHM/Cpanel)


    Setting up nameservers in WHM/Cpanel

    1. Log into WHM

    2. Goto Server Setup =>> Edit Setup

    Make sure your primary IP is correct under Main Shared Virtual Host IP

    Make sure your Hostname is correct under Hostname (server1.xyz.com)

    Under Primary Nameserver enter your primary nameserver (ns1.xyz.com), click on Assign Ip Address, then click on Add A entry for this nameserver

    Under Secondary Nameserver enter your secondary nameserver (ns2.xyz.com), click on Assign Ip Address, then click on Add A entry for this nameserver

    Note: You can add a third and fourth name server if you wish, however this is not necessary. All name servers will be automatically assigned to any accounts you setup later. You will have to manually disable extra nameservers from each account.

    Scroll to the bottom and click Save.


    Goto DNS Functions =>> Edit a DNS Zone

    Choose the primary domain for the server and click Edit

    The beginning of your Zone File should look something like this:


    -------------------------------------------

    ; Zone File for ip-2-ip.net


    $TTL 14400


    @ 14440 IN SOA ns1.xyz.com. admin.xyz.com

    -------------------------------------------


    In SOA add your primary ns (ns1.xyz.com.) and contact email (admin.xyz.com.). Put a period at the end of your nameserver, and use a period in place of @ in your contact email and add a period at the end too.)


    In most cases you should have the following Record Types:

    -------------------------------------------

    xyz.com. 14440 IN NS ns1.xyz.com.

    xyz.com. 14440 IN NS ns2.xyz.com.

    xyz.com. 14440 IN A 123.123.123.12 (primary IP Address)

    localhost.xyz.com. 14440 IN A 127.0.0.1

    xyz.com. 14440 IN MX 0 xyz.com.

    mail 14440 IN CNAME xyz.com.

    www 14440 IN CNAME xyz.com.

    ftp 14440 IN A 123.123.123.13

    ns1 14440 IN A 123.123.123.12

    ns2 14440 IN A 123.123.123.13

    server1 14440 IN A 123.123.123.12 (primary IP Address)

    -------------------------------------------


    If you do not have A records for your Nameservers add them now. If you use Managed DNS for your domain name, also add A records to your domain name with your DNS.

    If you made changes to your zone file, scroll down to the bottom and click on Save


    Goto DNS Functions =>> Perform a DNS Cleanup


    Now log out of WHM and SSH to your server and login as root.

    Note: You can download Putty by Clicking Here. It's a clean running application that will not require installation on Windows-boxes.

    Once logged in...

    At command prompt type: pico /etc/nameserverips

    Make sure all of your nameservers are listed

    123.123.123.12=ns1.xyz.com
    123.123.123.13=ns2.xyz.com
    123.123.123.14=0
    123.123.123.15=0
    123.123.123.16=0

    Remove any nameservers that do not belong.

    If you make changes to the file, then press the following keys on your keyboard Ctrl o and then Enter to save the file, then Ctrl x to exit.


    At command prompt type: pico /etc/resolv.conf

    There should only be three records in the resolv.conf file... localhost, primary nameserver, secondary nameserver.

    nameserver 127.0.0.1
    nameserver 123.123.123.12
    nameserver 123.123.123.13

    Remove anything else and then save and exit.


    At the prompt type: pico /etc/wwwacct.conf

    Make sure all of the information is correct. Remove anything that does not belong, save, then exit.

    LOGSTYLE combined
    MINUID
    NS ns1.xyz.com
    NS2 ns2.xyz.com
    ns3
    SCRIPTALIAS y
    ns4



    At the prompt type: pico /etc/named.conf

    Scroll down to the bottom of the file to the zone records.

    -------------------------------------------

    zone "xyz.com" {
    type master;
    file "/var/named/xyz.com.db";
    };

    -------------------------------------------

    Make sure all domain zone records are correct. Remove any zone records that are old or do not belong there. If you make any changes, save and then exit.


    At the prompt type: [B]pico /etc/host.conf[B]

    This file should look like this:

    order hosts,bind


    At the prompt type: pico /etc/host

    This file should look like this:

    -------------------------------------------

    # Do not remove the following line, or various programs
    # that require network functionality will fail.
    123.123.123.12 server1.xyz.com server1
    127.0.0.1 localhost

    -------------------------------------------


    Now your done and your nameservers will work like a pro.

    Hi there,

    I did like you said here but my name servers at whois.sc are still dns1.name-services.com.. My domain is thitsar.com. What's wrong?

    Those look like Namecheaps Managed nameservers, which is good. In this case, the nameservers for your domain are seperate from the nameservers on your host server. You should be fine.

    You still have to point your domain A record to your server and create a separate zone file for your domain on your server. I recommend sticking with Managed DNS, webhostingtalk.com...id=327467, this will have no effect on your server setup.

    By the way, I don't know ThePlanets policy, but you might ask them to register the Reverse IP record for your primary IP in your server's name.

    oops... My default config in wwwacct.conf is like this

    ADDR 67.19.217.20

    NS2 ns2.thitsar.com
    NS3
    SCRIPTALIAS y
    ns4

    but I played with it last night & change the addr to 67.19.217.18, which is another IP of my server. Then I couldn't access to any domains at the server as it said unable to resolve the IP address for that domain but still could enter into WHM & cPanel & ssh via IP addresses..

    So I changed back just now to .20.. Why does it happen?

    Your wwwacct.conf looks ok. It indicates that 67.19.217.20 is your primary IP Address, that gravity.thitsar.com is the server name, and that you have two name servers ns1.thitsar.com and ns2.thitsar.com setup.

    You need to get the IP addresses assigned to ns1.thitsar.com and ns2.thitsar.com and make sure they are the same IP addresses that you have listed for your nameservers at Namecheap (or whatever domain name registry you are using).

    Although you use Managed DNS and changes that you make to your domain records are propagated immediately, your registered nameservers will still take 24-48 hours to propagate.

    By the way, you should bind SSH to only one IP address as a security precaution webhostingtalk.com...threadid=327478.


    in my resolv.conf file.. there are only three entries for localhost, ns1 & ns2

    should I change it to

    domain thitsar.com
    nameserver 127.0.0.1
    nameserver 67.19.217.20
    nameserver 67.19.217.19
    If the IP assigned to your primary nameserver is 67.19.217.20, and the IP assigned to your secondary name server is 67.19.217.19... then your resolv.conf file should look like this:

    Code:
    nameserver 127.0.0.1
    nameserver 123.123.123.12
    nameserver 123.123.123.13
    Dark_Coder, I hope this helps you. If you are still having problems, PM me and I'll give you a hand.

    Hmmm, sorry I didn't think of that when I wrote the post. Every CPanel dedi I leased was already setup. It just never occured to me to add that.

    I read the guide wrong, and I accidently edited the nameservers instead of the actual domain, so in general what record types should I have for
    NS1 and NS2

    I also get this message when editing the Domains sometimes
    dns_master_load: /var/named/ns1.xyz.com.db.test:19: ignoring out-of-zone data (xyz.com)
    zone ns1.xyz.com/IN: loaded serial 2---1--1
    OK

    Bind reloading on admin using rndc zone: [ns1.xyz.com]
    Error reloading bind on admin rook: rndc: connect failed: connection refused

    Zone Modified!
    admin is the name of my subdomain that i used for the account

    also how long do the settings take to come into effect, once you have cleaned up and restarted the service

    Security Warning, your resolver configuration contains 127.0.0.1 (localhost). For security reasons, we recommend that you use a non-local dns resolver. Click here to change your configuration.

    I forgot to update the thread in this forum. So I'll do it now.

    Due to some recent exploit, CPanel has issued this Resolver warning. Just remove the line that says: nameserver 127.0.0.1 from /etc/resolv.conf

    At command prompt type: pico /etc/resolv.conf

    There should only be two records in the resolv.conf file... primary nameserver, secondary nameserver.

    nameserver 123.123.123.12
    nameserver 123.123.123.13

    Remove 127.0.0.1 and anything else and then save and exit.

    I've read that you can put a domain and search sentence in the resolv.conf file, is this useful?
