DNS區域文件驗證

Question

我無法使用DNS驗證DNS區域文件綁定自己的工具named-checkzone。

下面是示例DNS區域文件（sample.txt的）：

$TTL 86400 ; 24 hours could have been written as 24h or 1d 
; $TTL used for all RRs without explicit TTL value 
$ORIGIN example.com. 
@ 1D IN SOA ns1.example.com. hostmaster.example.com. (
        2002022401 ; serial 
        3H ; refresh 
        15 ; retry 
        1w ; expire 
        3h ; minimum 
       ) 
     IN NS  ns1.example.com. ; in the domain 
     IN NS  ns2.smokeyjoe.com. ; external to domain 
     IN MX 10 mail.another.com. ; external mail provider 
; server host definitions 
ns1 IN A  192.168.0.1 ;name server definition  
www IN A  192.168.0.2 ;web server definition 
ftp IN CNAME www.example.com. ;ftp server definition 
; non server domain hosts 
bill IN A  192.168.0.3 
fred IN A  192.168.0.4 

而且我運行以下命令：

named-checkzone local sample.txt 

然而，發現了以下錯誤而無法根本原因問題。

sample.txt:4: ignoring out-of-zone data (example.com) 
sample.txt:15: ignoring out-of-zone data (ns1.example.com) 
sample.txt:16: ignoring out-of-zone data (www.example.com) 
sample.txt:17: ignoring out-of-zone data (ftp.example.com) 
sample.txt:19: ignoring out-of-zone data (bill.example.com) 
sample.txt:20: ignoring out-of-zone data (fred.example.com) 
zone local/IN: has 0 SOA records 
zone local/IN: has no NS records 
zone local/IN: not loaded due to errors. 

我感謝任何反饋/指針。

named-checkzone的第一個參數是區域名稱。所以你要求它檢查「本地」區域。而example.com確實不在該區域。
