How to test DNS?

Is there a way to test internally if the DNS server is working properly. I did http://www.intodns.com/lampxserver.com and have nameserver issues.

My router is forwarding port 53 to ns1 and these are my DNS settings:

Code:

Yes A lampxserver.com. 67.191.52.236 0  
Yes A mail 67.191.52.236 0  
Yes A www 67.191.52.236 0  
Yes MX lampxserver.com. mail1.lampxserver.com. 10  
Yes NS lampxserver.com. ns1.lampxserver.com. 0  
Yes NS lampxserver.com. ns2.lampxserver.com. 0 

 

I figured out that my nameserver are not being resolved internally, how can I fix this... I changed the IP address of the hostname ns1.lampxserver.com to 192.168.10.151 and it now works... Why does it not resolve the internal IP?

 

you can try dig from localhost to extern IP

 

Does anyone have any mapping guides to go by to efficiently map DNS records to internal server.

 

One problem I am trying to figure out. Or rather a few problems:

I have my phpmyadmin on my db1 server running an apache instance.
I wish to make ispconfig on the panel server connecter to the phpmyadmin on the db server, how can I do that. one method I tried was:

First removing the /phpmyadmin from ispconfig server configuration then.
Using ssh to open the panel server that has the ispconfig web shell

Code:

nano /usr/local/ispconfig/interface/web/sites/database_phpmyadmin.php


    if($global_config['phpmyadmin_url'] != '') {
        $phpmyadmin_url = $global_config['phpmyadmin_url'];
        $phpmyadmin_url = str_replace('[SERVERNAME]',$serverData['server_name'],$phpmyadmin_url);
        header('Location:'.$phpmyadmin_url);
    } else {
        isset($_SERVER['HTTPS'])? $http = 'https' : $http = 'http';
        $http = 'http'; : just insert this line exactly here.
        if($web_config['server_type'] == 'nginx') {
            header('location:' . $http . '://' . $serverData['server_name'] . ':8081/phpmyadmin');
        } else {
            header('location:' . $http . '://' . $serverData['server_name'] . '/phpmyadmin');
        }
    }

I added the $http = 'http'; then I created an A record for db1 to the internal IP address of the database server which was called db1.domain_name.com

That of course did not work internally on the network or externally.

How can I correct this?

 

I have a glue record for my domain lampxserver.com but when I create the site and add the DNS records it does not work, here are the results:
http://www.intodns.com/lampxserver.com

But another domain using the same Nameservers ns1.lampxserver.com and ns2.lampxserver.com works fine:
http://www.intodns.com/ahostgroup.com

using the same DNS record settings... Am I not able to use the domain of my name servers? or how can I fix this.
