  directory "/var/named";
  pid-file "/var/named/named.pid";
  forwarders { 202.101.224.67; 202.101.224.68; };
  allow-query { any; };
};
zone "." IN {
  type hint;
  file "named.root";
};
zone "0.0.127.in-addr-arpa" IN {
  type master;
  file "named.local";
  allow-update { none; };
};
zone "df3c.com" IN {
  type master;
  file "named.df3c.com";
  allow-update { none; };
};
zone "1.168.192.in-addr-arpa" IN {
  type master;
  file "named.1.168.192";
  allow-update { none; };
};

# dig /var/named/named.root

# vi /var/named/named.local

输入以下内容：

$TTL 3h
0.0.127.in-addr.arpa. IN SOA terminator.df3c.edu. wumh@df3c.com. (
                      1      ; Serial

www             IN A  192.168.1.226
*                  IN A  192.168.1.240

# vi /var/named/named.1.168.192
输入以下内容：

$TTL 3h

三、启动

# /usr/sbin/named -g &
注：-g显示启动时的日志，一边分析启动过程出现错误的原因。

# ps -eaf|grep named

# netstat -an |grep :53

?

四、开启dns防火墙

# iptables -I INPUT -p tcp --dport 53 -j ACCEPT
# iptables -I INPUT -p udp --dport 53 -j ACCEPT

# /etc/init.d/iptables save
# service iptables restart
# /etc/rc.d/init.d/iptables status
