    * URGENT: Nameservers are not reachable !!

    Hi Guys,

    I have created 2 nameservers and assigned unique IPs to them and I have my domain dhingana.org using them. Everything was fine until today when suddenly I cannot reach dhingana.org.

    I restarted BIND, Apache and even my server but still the same issue. I checked that Apache is still running.

    My DNS reports for dhingana.org says:

    A timeout occurred getting the NS records from your nameservers! None of your nameservers responded fast enough. They are probably down or unreachable. I can't continue since your nameservers aren't responding. If you have a Watchguard Firebox, it's due to a bug in their DNS Proxy, which must be disabled (31 Jul 2006 UPDATE: several years after being informed of this, there is a rumor that there is a fix that allows the Watchguard DNS proxy to work).

    Any idea why?

    Thanks,
    Swapnil

    The nameserver setting is correct. The problem is that domain is not resolving from the server.

    You can verify this by issuing the command inside the server

    dig dhingana.org @localhost

    Try recreating db record of this domain in the server

    Hi,

    The issue is with your ns2 nameserver. ns1 is responding, but ns2 is not. You will need to check this.

    Its working fine now. See http://www.dnsstuff.com/tools/lookup...ana.org&type=A

    But, I see the error " You don't have permission to access / on this server."

    Please check the permissions on the folder /home/user , /home/user/public_html etc.

    You will need to check why ns2 is not responding.
    Dnsstuff is giving Dns broken error.
