Need DNS coaching, please

    Have just installed ISPConfig 3 and managed to to make it work to ~95%. When it comes to DNS configuration, I'm just a newbie. Made some self-studies on the internet about DNS and got some sort of grip on the matter. But thats all.

    My ISPConfig server is hosted on VPS from a ISP. They also provides their DNS server for my domain, where I can configure records through a panel.

    I have only changed the IP-address in the default ISP settings, where "123.456.789.12" is the IP for the server which runs ISPConfig. They look like this:

    Code:
    Subdomain	Type	TTL	Data	
    @		A	3600	123.456.789.12
    www		A	3600	123.456.789.12
    (IP adresses are fictive)

    In the DNS records in the ISPConfig 3 panel, I have the following entries:

    Code:
    A	domain.com.	123.456.789.12		0	3600
    A	mail		123.456.789.12		0	3600
    A	www		123.456.789.12		0	3600 	
    MX	domain.com.	mail.domain.com.	10	3600 	
    NS	domain.com.	ns1.domain.com.		0	3600 	
    NS	domain.com.	ns2.domain.com.		0	3600
    (Domains and IP adresses are fictive)

    I can reach the website on www.domain.com without problems.

    But when I make a ping to the mail.domain.com, ns1.domain.com, ns2.domain.com from an "outside" computer, I receive the "Unknow host" message. So something is not properly configured for sure.

    Any suggestions, please...?
    Kind regards

    Hi Milleman,

    Before doing the stuff below, add A records for your name servers:

    Code:
    A    ns1    123.456.789.12
    A    ns2    123.456.789.12
    
    If that doesn't work, try this....

    Even though you setup DNS records, you still have to setup your glue records with your registrar. domail.com is registered with someone, so go to that someone and make sure you set this for domain.com:

    Name Servers:
    ns1.domain.com
    ns2.domain.com

    Also, the ns1 and ns2 servers must be available publicly, which means they will have some IP that can be seen by other external computers.

    If your name servers are not on the Internet, check out dnsexit.com. They provide name server services at no charge.

    My guess is that's your problem, since you can reach them via IP ping.

    Hello Darin,

    Thank you for your reply!
    I tryed setting the following in my ISP-provider's DNS panel:

    Code:
    Subdomain	Type	TTL	Data	
    ns1		A	3600	123.456.789.12
    ns2		A	3600	123.456.789.12

    The DNS settings in ISPConfig 3 (123.456.789.12) are the same as behore:

    Code:
    A	domain.com.	123.456.789.12		0	3600
    A	mail		123.456.789.12		0	3600
    A	www		123.456.789.12		0	3600 	
    MX	domain.com.	mail.domain.com.	10	3600 	
    NS	domain.com.	ns1.domain.com.		0	3600 	
    NS	domain.com.	ns2.domain.com.		0	3600
    Now I can ping ns1.domain.com & ns2.domain.com and receive a response back.
    But I have lost the response from www.domain.com instead. The mail.domain.com isn't reponding either, just like before.
    To me it seems like the ISPConfig DNS settings doesn't have any effect, even though everything is there.

    Hi Milleman,

    With domain registrar, you should place ns1.domain.com, and ns2.domain.com as your name servers. This is called a glue record for your domain.com domain.

    In ISPConfig3 you need these:
    Code:
    ns1		A	3600	123.456.789.12
    ns2		A	3600	123.456.789.12

    Hi Darin,

    I changed the following:

    In my registrars DNS-panel:
    Code:
    Subdomain	Type	TTL	Data	
    ns1		NS	3600	domain.com
    ns2		NS	3600	domain.com

    The DNS settings in ISPConfig 3 (123.456.789.12) are the same as behore:

    Code:
    A	domain.com.	123.456.789.12		0	3600
    A	mail		123.456.789.12		0	3600
    A	www		123.456.789.12		0	3600
    A	ns1		123.456.789.12		0	3600
    A	ns2		123.456.789.12		0	3600
    MX	domain.com.	mail.domain.com.	10	3600
    Is this correct?

    Can't ping anything on that domain now. :(
    Sorry if I can't understand your suggestions correctly...

    Okay, I now understand what you meant! I found the Domain Setup page at my domain registrar control panel, which is different from the DNS records panel. I will put the glue record "ns1.domain.com" and "ns2.domain.com" in place, instead of my ISP:s default glue records for their DNS server.

    Hope this works better.
    Many thanks to you Darin! :)

    Great! Did you get everything working?

    Not quite there yet.

    If I check the ISPConfig www from outside, I get the following:

    Host www.domain.se not found: 5(REFUSED)

    Could it be that the ISPConfig DNS doesn't allow queries from outside?
    Do I need to set "allow-query { any; };" to the DNS?
    If yes, is it possible to do it in the ISPConfig Panel or do I have to make it in the Bind configuration file manually?
