    Thst the normal behaviour of mydns, as mydns does not dontain a resolver library. Solution is to install a dns resolver like dnsmasq.

    Follow the steps that are described in the chapter "Installing DNSMasq" from here (and only this chapter and not the whole tutorial):

    1) Have you reconfigured the mydns.conf file as described?
    2) Have you restarted mydns?
    3) Post the content of /etc/resolv.conf

    What's in mydns.conf? What's the output of
    Code:
    netstat -tap
    ?

    I have a very similar problem. When I try to bring up my domain name it gets stuck on "resolving host" and then times out. I already switched the name servers over.

    When I dig mydomain.com, it yields this:

    Code:
    root@server1:~# dig mydomain.com
    
    ; <<>> DiG 9.7.0-P1 <<>> mydomain.com
    ;; global options: +cmd
    ;; Got answer:

    This is in my /etc/dnsmasq.conf file:

    Code:
    no-listen = 127.0.0.1
    recursive = 127.0.0.1
    
    I followed all of the directions in the tutorial that was linked earlier in this thread. The contents of my configuration files are exactly what that tutorial suggested.




    "Netstat -tap" yields this:

    Code:
    root@server1:~# netstat -tap

    I have a very similar problem. Whenever I go to my domain name, it gets stuck on resolving host and then times out. I entered the correct name servers, and it looks like its forwarding when I do a dig mydomain.com:

    I followed all the configuration instructions in the tutorial posted above and made the appropriate entries in ISPconfig under DNS and site.


    Here is the output of my netstat -tap:

    Edit: I also forgot to mention that when I ping my domain name, it does ping my ip address. It never stops pinging it though, and it displays a hostname from my service provider...

    I followed the perfect setup guide for ubuntu server 10.04, and everything else seems to be working perfectly. Both ns1.nameserver.com and ns2.nameserver.com point to the same IP address. Is this a problem? I had no problem entering those servers with the registrar.

    Hehe, quite a few:



    Also... Is the intended behavior for my name servers (ns1.nameserver.com, etc) to point to the default server webpage? When I type in ns1.nameserver.com it gives me this message:

    That sounds as if you didn't set any nameservers for that domain in your registrar's web interface...
