dns无法启动named进程，为之奈何？

薛宝钗

我手动启动named可以:
sudo -u named named -g
然后输出信息：
Nov 14 10:33:54.914 starting BIND 9.2.1 -g

Nov 14 10:33:54.967 zone 1.1.10.in-addr.arpa/IN: sending notifies (serial 2)
为什么这里面很多ingored和denied的消息呢？
然后我查询named的状态：
# service named status
rndc: connect failed: connection refused
连接不上
然后我nslookup试一下自己的ip：
> 101.1.1.208
Server:         202.106.196.115
Address:        202.106.196.115#53

** server can't find 208.1.1.101.in-addr.arpa: NXDOMAIN
>
也是不行的

我又试了一下拿root帐户启动named的情形，就所有功能都正常了，查自己的ip，自己设置的地址都出来了，这又是怎么回事呢？
