  1. Olá amigos,

    Estou achando estranho a quantidade enorme de registro no syslog referentes ao bind9.

    Alguém tem idéia do que isto se trata?

  3. Código :
    # cat /etc/bind/named.conf.options
    options {
            directory "/var/cache/bind";
            forwarders {
              201.10.1.2;
              208.67.220.222;
              201.10.120.3;
              208.67.220.220;
            };
     
            listen-on {127.0.0.1; 192.168.1.1; 192.168.11.1; 192.168.3.1;};
            allow-query {192.168.1.0/24; 192.168.11.0/24; 192.168.3.0/24;};
            allow-recursion {192.168.1.0/24; 192.168.11.0/24; 192.168.3.0/24;};
            allow-transfer {none; };
     
            auth-nxdomain no;    # conform to RFC1035
            listen-on-v6 { none; };
    };

    Esta é minha configuração para cache de dns somente.

    Obrigado pela atenção Alexandre.
