[DNS] rh9 下配置DNS遇到的错误，请DNS高手帮忙

[老栗子]

etc/named.conf(增加的内容如下)

zone  "ifnc.com"{
     type master;
     file "ifnc.com.hosts";
     };

zone "0.168.192.in-addr.arpa" IN{
     type master;
     file "192.168.0.rev";
     };

正向解析数据库 ifnc.com.hosts 内容如下：

$tt1 1D
@  IN SOA  shrike.ifnc.com.  root.shrike.ifnc.com.
(   
1053891162
3H
15M
1W
1D
)   


  IN  NS  shrike.ifnc.com.
  IN  MX  5  shrike.ifnc.com.
shrike   IN  A  192.168.0.130
www      IN  CNAME shrike.ifnc.com.

反向192.168.0.rev内容如下：

$tt1 1D
@ IN SOA shrike.ifnc.com. root.shrike.ifnc.com.
(
    1053892104
    3H
    15M
    1W
    1D)
    IN   NS   shrike.ifnc.com.
130 IN   PTR  shrike.ifnc.com.
