    I have been trying to setup a PTR record and or RDNS on my server which I kept getting errors all the time and when I got to set it up clean with no Errors it's not working or I cannot get my Registrar to register a domain on it.

    I have configured two ISPConfig Server's one being the main hosting server with with all services and the other one as a secondary DNS Server both using a Single interface.

    I have an IP range of 197.228.128.0/24 and the main server is using a Static IP of 197.228.128.21/24 and the Secondary server is on 197.228.128.33/24.

    And What I need to know is how do I configure RDNS for these servers to get my Registrar to register my domains on it.
    I have downloaded the ISPConfig book which has made me more confused than I was before and there is no Section providing proper and clear explanasion on how to get this to work.

    Searching the net for answers has let me to find more people having issues and with no proper solutions.

    This is what I get from the Registrar when registering the domain's and their support has advised me that the RDNS is not working.

    Provided Nameserver information
    Primary Server : ns1.somedomain.co.za
    Secondary 1 : ns2.somedomain.co.za

    The rdns should not be related to registering a domain as no registra checks rdns, so these are probably 2 non related issues.

    So we should start with the dns zone of the domain that you want to register first, please post a screenshot of the dns zone that you added in ispconfig and a screenshot of the records tab of that zone. The Message "ERROR: No valid nameservers found - rejecting request." refers to the dns zone, it is not related to reverse dns.

    Regarding rdns record, there are detailed step by step instructions with screenshots on how to create a verse dns record in the ispconfig manual, as howtoforge subscriber you can download the ispconfig manual here:

    https://www.howtoforge.com/download-the-ispconfig-3-manual

    But it is unlikely that you have to add a rdns record at all as such a rdns record is the dns record of the IP and is added by the ISP that manages this subnet and not be the user that uses this subnet on its server.

    The records look fine doe far. the ns1 and ns2 a-records are not necessary as the dns server of this zone is not the zone itself, but it does not hurt that they exist, they will just not be used.

    I tested your dns record and it works fine, both ns servers are responding properly for the domain, so the dns setup is correct.

    The domain dfhostedservices.co.za is setup on nameservers ns1.datafusion.co.za and ns2.datafusion.co.za, you can send them the dig output from above.

    Hi

    I gave my registrar all the details and they advised that There are no PTR records on my name server's.
    Is there a way that I can add just one PTR record to use with any domain I register on My ISPConfig?

    Thanks and Regards
    Ernest Manamela

    A PTR record is the dns record of the IP and not the domain, so a PTR is not domain specific. Normally the PTR is set by the datacenter where you host the server or the internet access provider that assigned you the IP. The PTR is not related to the registration of a domain, so I have no Idea why the insist on a PTR. As the provider where you got the Ip address of this server from ify they maintain the ptr or if the delegated the PTR for this IP subnet to your server. If they tld you that the DNS for this IP is delegated to you, then add a reverse zone for this IP address as described in the ISPConfig manual.

    Hi

    I can confirm that we own the IP Range that I'm using. Capture3.JPG Capture4.JPG

    Do you see any errors in the syslog file for bind / named when you restart bind?

    this is what I get pri.107.221.197.in-addr.arpa.err

    Bind is restarting fine.

    service bind9 restart
    * Stopping domain name service... bind9 waiting for pid 1053 to die
    [ OK ]
    * Starting domain name service... bind9

    Ok, this means that Bind rejected the dns zone. you can test the pri.107.221.197.in-addr.arpa.err zone file with the named_checkzone tool from BIND to see why it got rejected.
