  • Hi,

     

    Thanks for your help but... how can i disable the recursion for all external IP addresses ?

    should i edit :

    named.conf  or named.conf-default ?

    named.conf is showing the following:

    options {
    directory "/zones";
    listen-on port 53 { any; };
    listen-on-v6 port 53 { any; };
    use-v4-udp-ports { range 24576 45055; };
    use-v6-udp-ports { range 24576 45055; };

    max-ncache-ttl 900;

    check-names master ignore;
    check-names slave ignore;
    check-names response ignore;

    pid-file "/var/run/named.pid";

    datasize default;
    stacksize default;
    coresize default;
    recursion yes;
    allow-recursion { any; };

    .......

    -->I believe that a RNDC reload is needed after

     

    Thanks for your help
