緩存DNS和Master DNS之間無防火牆隔離。
RHAS3
DNS套件：bind-9.2.2-21； bind-utils-9.2.2-21； caching-nameserver-7.2-7
[root@localhost root]# more /etc/named.conf
options {
directory "/var/named";
forward only;
forwards {192.168.176.33;}; //192.168.176.33為正在服務的master DNS服務器地址。
};
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
include "/etc/rndc.key";
1．3 自己創建文件/etc/resolv.conf，內容如下：
[root@localhost root]# more /etc/resolv.conf
nameserver 192.168.176.66 //高速緩存DNS服務器自身的IP地址。
search localdomain
nslookup測試結果總是提示timed out。

我打算建設高速緩存DNS服務器，但是沒成功，望指點！
