WARNING: One or more of your nameservers did not return any of your NS records.

Hi,
I need some help making a website live.
I tested www.intodns.com and it says my site has a number of errors:

www.intodns.com gives errors:
Error Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records.
Error DNS servers responded ERROR: One or more of your nameservers did not respond:
The ones that did not respond are:
WAN IP.

Error Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.

Error Missing nameservers reported by your nameservers You should already know that your NS records at your nameservers are missing, so here it is again:

ns2.domain.com.
ns1.domain.com.

SOA Error SOA record No valid SOA record came back!
MX Error MX Records Oh well, I did not detect any MX records so you probably don't have any and if you know you should have then they may be missing at your nameservers!
WWW Error WWW A Record ERROR: I could not get any A records for www.domain.com!

(I only do a cache request, if you recently added a WWW A record, it might not show up here.)

Any suggestions please?

Hi and welcome to LQ,

Without the zone file it's difficult to find what's wrong.
So please post your zone file, masking sensitive data (domain name and real IPs) if you want.

Regards

Thank you for the reply.
I think this is the zone file which I found in etc/named.conf/, however it doesn't look like the right details compared to an example I found online https://www.virtualmin.com/node/15567:

Code:

$ttl 38400
yourdomain.com.    IN    SOA    ns1.yourdomain.com. webmaster.yourdomain.com. (
            1055026205
            6H
            1H
            5D
            20M )
yourdomain.com.        IN    A     1.2.3.4
mysql.yourdomain.com.  IN    A     1.2.3.4
www.yourdomain.com.    IN    CNAME yourdomain.com.
ns1.yourdomain.com.    IN    A     1.2.3.4
ns2.yourdomain.com.    IN    A     1.2.3.5
yourdomain.com.        IN    NS    ns1.yourdomain.com.
yourdomain.com.        IN    NS    ns2.yourdomain.com.
mail.yourdomain.com.   IN    MX    1 yourdomain.com.

I guess this is not the zone file in question, as this one has no errors.
Since you're running RHEL (or clone) the zone file should be located under /var/named (or under /var/named/chroot/var/named if you're running bind chrooted).

Thank you, yes, I found it in /var/named.

Here are the Zone file results:

Code:

$ttl 38400

                        3600
                        604800
                        38400 )
@       IN      NS      localhost.localdomain.

Also, I think the issue is port 53 not receiving and/or letting packets through.
I need to figure out how to open port 53, as I have port forwarded port 53 on my router.

I will address this issue first as apparently this is the 1st priority before I check the Zone file.

Do that and also change the NS record to read

Code:

@       IN      NS      domain.com.

or else your domain will not be resolvable
