请各位帮忙看看，配置的dns还是无法解析域名！[已解决]

w80286

各位，我在学习搭建dns,用的CENTOS 5.4的OS，现在named能正常启动了，但是我已经配置好的域名查询不到,请各位帮忙看看又是哪里出问题了，谢谢。

这个是系统日志：

w80286

在启动的过程中，只看到有一条错误信息：
May  6 20:00:17 localhost named[8287]: the working directory is not writable
不知道这个是哪里出了问题

语法检查做了么

你机器的 IP 是动态分配的把？

不是，是静态IP。
这个是我今天修改过的正向解析文件：
[root@localhost named]# cat named.test.com
$TTL 600
@ IN SOA  test.com.  root.test.com.(2006102003 28800 14400 72000 86400)
IN NS test.com.
IN A 222.196.70.38
www IN A 222.196.70.38
目前正解能解析了，但反解还是不成功，反解文件如下：
[root@localhost named]# cat named.222.196.70
$TTL 600
@ IN SOA test.com. root.localhost.(2006102005 28800  14400 3600000  86400 )

@ IN NS test.com.
38 IN PTR test.com.

回复 5# w80286


    你的反解换成这个尝试下：

原文件：

38 IN PTR test.com.

修改后的文件

38 IN PTR  www.test.com

还是不行哈。
百湖大哥说让我用named-checkzone检查一下语法错误，我下午检查过了，没有报错。

chenyx

zone "70.196.222"{
改成zone "70.196.222.in-addr.arpa" {
试试

w80286

zone "70.196.222"{
改成zone "70.196.222.in-addr.arpa" {
试试

经过楼上各位朋友的指点，现在反解能正常解析了，非常感谢。
修改后的部分named.conf文件：
zone "70.196.222.in-addr.arpa"{
type master;
file "named.222.196.70";
};
修改后的反解文件:
[root@localhost named]# cat named.222.196.70
$TTL 600
@ IN SOA test.com. root.localhost.(2006102005 28800  14400 3600000  86400 )
@ IN NS  test.com.
38 IN PTR www.test.com.

执行结果：
[root@localhost named]# /etc/init.d/named restart
Stopping named:                                            [  OK  ]
Starting named:                                            [  OK  ]
[root@localhost named]# nslookup

Server:         222.196.70.38
Address:        222.196.70.38#53

38.70.196.222.in-addr.arpa      name = www.test.com.

zone "70.196.222.in-addr.arpa"正确的写法后面应该用个'IN'的
