Bind configuration

[Amira Othman]

Hi all 

I have configured bind9 on centos 5.8 but I still can't nslookup my domain.
Below are my configuration:


Named.conf

key "rndckey" {
        algorithm       hmac-md5;
        secret
"jQdcyY1HIkooWVB24Dr4uX5jrVcuZFNEJaGa9Q5e3otOjSrcMVGOwhACivlX";
};
options {
directory "/var/named";
pid-file "/var/run/named/named.pid";
zone "cairosource" {
        type master;
        notify no;
        file "cairosource.zone";
};

Zone file

; BIND db file for cairosource.com

$TTL 86400
