[已解决]CentOS下配置DNS+DHCP动态更新老是不成功...权限原因.

搜索了一下论坛,发现以前有人提过这样的问题:http://bbs.chinaunix.net/thread-1080803-1-1.html

我现在就两台机器,同接在一个交换机下面.

机器1. CentOS 5.  BIND-9.3.6;    DNS与DHCP就安装在此台机器上面;   IP:192.168.203.100

机器2. windows xp sp3.              这是作为测试的客户端. 机器名:test;   IP:192.168.203.101


配置好CentOS作为DNS与DHCP服务器后,现在windows xp 端可以正常从CentOS上面自动获取到IP地址与DNS这些信息.但为何在CentOS DNS的区域文件(example.com.db)里没有发现xp这台机器的A记录呢?

我尝试在CentOS上执行nsupdate

>server 127.0.0.1
>update add test.example.com 600 A 192.168.203.101
>send
update failed: REFUSED


/var/named/chroot/var/named下面也没有以jnl为扩展名的文件名.........
为什么啊?
