我的DNS配置文件，请大家帮忙看看，谢谢！

luronghui

我的主机名：server.com
系统：RedHat企业服务器4。0
IP:192.168.38.126
要解析的域为： example.com
下面贴出我的配置文件，请大家看看。

你的dns不好用吗？

bwb

你的NS服务器到底是192.168.38.126 还是192.168.38.1？
反向解析呢？
你到底要解析server.com还是 example.com ？
问题多多，首先你就没有搞清楚其意义。

narafans

zone "example.com" IN {

type master;

file "name2ip.conf";

IN NS server.com.

IN A 192.168.38.1
应该是错误

luronghui

这样的，我的主机是server.com   IP  是192.168.38.126
我要解析的域名是： example.com   对应的IP是 192.168.38.1
我现在正向解析还不行，就没有弄反向解析的了！
请你看看！
谢谢！

这样看看，不知道对不对..

好的，我试一试。
谢谢您！

luronghui

我试了一下，还是那个问题。
显示：
＃nslookup
>www.example.com
Server: 192.168.38.126
Address: 192.168.38.126#53

**server can't find  www.example.com SERVFALL
>

如果使用localhost就可以的。
＃nslookup
>localhost
Server: 192.168.38.126
Address: 192.168.38.126#53

Name: localhost
Address: 127.0.0.1
我还能怎么办呢？
谢谢您！

bwb

www.example.com 没有解析出来

narafans

host www.example.com
什么反应？
把localhost那行删掉看看

bwb

1.首先简化你的/etc/named.conf，里面需要有类似这两个：
...
zone  "38.168.192.in-addr.arpa" {
        type master;
        file  "38.168.192.in-addr.arpa.zone";
};

zone  "example.com" {
        type master;
        file   "example.com.zone";
};
...
第一个是反向解析，就是从IP解析到域名。第二个是正向解析，就是从域名解析到IP。

luronghui

host www.example.com
显示：
Host www.example.com not find:2(SERVFAIL).

楼上的楼上说的很对
建议你还是重新写你的配置文件
别用默认的改
那样很容易出错的
