    DNS woes

    I've recently run into problems with DNS on my web server. It is a dedicated server with full access running Fedora Core 5 with CPanel and WHM. Anyway, I started having problems sending E-Mail and then CPanel reported an invalid license.

    After trying to refresh the license key, I found out to my dismay that my server could not look up ANY external domains.

    My resolv.conf looks like this:


    I modified that from this, which was generated by dhclient-script but I believe to be wrong:

    ; generated by /sbin/dhclient-script

    Using the latter, dig/nslookup times out, though using the former I get a response albeit nothing in the "reply" section.

    A sample for dig is as follows:

    root@layla [/]# dig

    ; <<>> DiG 9.3.1 <<>>
    ;; global options: printcmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 54372
    ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 13, ADDITIONAL: 0

    ; IN A

    . 3600000 IN NS A.ROOT-SERVERS.NET.
    . 3600000 IN NS B.ROOT-SERVERS.NET.
    . 3600000 IN NS C.ROOT-SERVERS.NET.
    . 3600000 IN NS D.ROOT-SERVERS.NET.

    . 3600000 IN NS F.ROOT-SERVERS.NET.
    . 3600000 IN NS G.ROOT-SERVERS.NET.
    . 3600000 IN NS H.ROOT-SERVERS.NET.
    . 3600000 IN NS I.ROOT-SERVERS.NET.
    . 3600000 IN NS J.ROOT-SERVERS.NET.
    . 3600000 IN NS K.ROOT-SERVERS.NET.
    . 3600000 IN NS L.ROOT-SERVERS.NET.
    . 3600000 IN NS M.ROOT-SERVERS.NET.

    ;; Query time: 1 msec

    I'm at a real loss as to what went wrong and why seeing as though the server has been largely happily chugging along for months without a problem. Obviously something has gone astray but I don't know what.

    Any ideas would be more than appreciated.

    it looks like you don't have any "a records" setup in your dns settings. log into your WHM and see if you can find the DNS settings to create some A-Records. I've forgotten how to do this in cpanel as I haven't used it in a few years but I am pretty sure you can do it from WHM.
