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
?
