我在公司内网的服务器上安装DNS软件：bind-9.3.4-1.23， 操作系统为SuSE10

> server 127.0.0.1
> zone hello.com.cn
> update add test.hello.com.cn 60 IN A 192.7.130.179
> show

我的named.conf（只贴zone）zone "hello.com.cn" in { 
  type master;
  file "hello.com.cn.zone";
  allow-update {127.0.0.1;};
  allow-transfer {none;127.0.0.1;};
};


我的zone文件
IPC209:/var/lib/named # cat hello.com.cn.zone 
$TTL 1W
@ IN SOA @ root (
  42 ; serial (d. adams)
  2D ; refresh
  4H ; retry
  6W ; expiry
  1W ) ; minimum
@ IN NS www.hello.com.cn.
www IN A 192.7.205.25
oa IN CNAME www
bbs IN CNAME www
dns IN A 192.7.205.25
ipc IN A 192.7.130.179

你把SElinux关闭试试，输入命令：setenforce 0
