帮我看看这ＤＮＳ错在哪！

smileyg

Fedora Core 1 系统下配的ＤＮＳ，正向解析正常，反向解析时提示：
ｓｅｒｖｅｒ　ｃａｎ＇ｔ　ｆｉｎｄ　２．１．１６８．１９２．ｉｎ－ａｄｄｒ．ａｒｐａ：ＤＸＤＯＭＡＩＮ

一下是代码帮我看看哪错了。 我刚接触LINUX，有些本质的问题不明白，请指点的清楚点。

/var/named/ip2name.conf
$TTL 86400
@ IN SOA www.yao.com. root.www.yao.com.
(2000062900;
28800;
14400;
3600000;
86400);
IN NS www.yao.com.
2 IN PTR www.yao.com.
2.1.168.192.IN-ADDR.ARPA. IN PTR www.yao.com.
@ IN MX 10 www.yao.com.

zone "2.1.168.192.in-addr.arpa" IN {
type master;
file "ip2name.conf";
allow-update { none;};
};

这两部分的问题，如果不修改named.conf，也就是保持

1. zone "2.1.168.192.in-addr.arpa" IN {
   
2. type master;
   
3. file "ip2name.conf";
   
4. allow-update { none;};
   
5. };

复制代码

那么var/named/ip2name.conf 应该为

1. $TTL 86400
   
2. @ IN SOA [url]www.yao.com[/url]. root.[url]www.yao.com[/url].
   
3. (2000062900;
   
4. 28800;
   
5. 14400;
   
6. 3600000;
   
7. 86400);
   
8. @    IN PTR [url]www.yao.com[/url].
   

复制代码

就可以了。
