    I'm running a Debian 6 server and I uses the single server tutorial. I can't get dns to work. When I type:

    Code:
    [email protected]:~# dig @localhost censeoenergy.co.uk
    
    ; <<>> DiG 9.7.3 <<>> @localhost censeoenergy.co.uk
    ; (1 server found)
    ;; global options: +cmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 49647
    ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
    
    ;; QUESTION SECTION:

    ;; ANSWER SECTION:

    ;; AUTHORITY SECTION:

    censeoenergy.co.uk.     86400   IN      NS      ns1.sitemamba.com.
    
    ;; ADDITIONAL SECTION:

    ns2.sitemamba.com.      34826   IN      A       91.121.172.34
    
    ;; Query time: 0 msec

    ;; WHEN: Tue Dec 20 02:58:56 2011
    ;; MSG SIZE  rcvd: 133
    
    
    All goes well. However, when I type:

    Code:
    [email protected]:~# dig @91.121.172.34 censeoenergy.co.uk
    
    ; <<>> DiG 9.7.3 <<>> @91.121.172.34 censeoenergy.co.uk
    ; (1 server found)
    ;; global options: +cmd
    ;; connection timed out; no servers could be reached
    
    It times out and I get no response. What is wrong?

    Thanks,

    James

    What are the outputs of
    Code:
    netstat -tap
    and
    Code:
    iptables -L
    ?

    Fixed it now. Bind was not listening on anything other than localhost.

    Hi Jamesl22,

    I have the same DNS problem, can you give some detail how to fix it? Thanks.

    Edit /etc/bind/named.conf.options and change the lines:
    Code:
    listen-on{ 127.0.0.1; }
    allow-recursion{ 127.0.0.1; }
    
    To read:

    Code:
    listen-on{ all; }
    allow-recursion{ all; }

    I can not find /etc/bind/named.conf.options. (may be i'm using SUSE)
    Will keep looking. Many thanks anyway.

    What's in your /etc/named.conf?

    This line:

    Code:
    #listen-on port 53 { 127.0.0.1; };
    Must read:

    Code:
    listen-on port 53 { any; };

    Try it, but still no good. Will re install the O/S and start from the beginning. Many thanks.

    Ok, I suggest you use debian this time round. It will solve you a lot of bother.
