又是DNS问题，

thizlinux

我在自己的机器上作测试，但用dig>named.ca得到的根域数据库文件老是这样，下面的是我用dig>named.ca命令得到的named.ca文件内容
; <<>> DiG 9.2.2 <<>>
;; global options: printcmd
;; connection timed out; no servers could be reached
不管我用啥命令测试DNS服务器都是;; connection timed out; no servers could be reached
我现在用host或是nslookup或dig命令测试dns都显示;; connection timed out; no servers could be reached
是不是就是因为我的named.ca根域数据库文件没有我的域和IP地址？
下面的是我的测试DNS后的系统日志

那位大侠帮忙解决一下，看看小弟的问题出在那，怎样解决，非常感谢！

named.ca当然没有你的域，你需要自己建你的域名数据库，类似这样的文件：
/var/named/your_domain.com.zone
/var/named/0.168.192.in-addr.arpa.zone
具体写法搜索文章

建自己的数据库文件我知道，问题是我现在都建好拉，但就是一测试就显示
;; connection timed out; no servers could be reached

贴你的conf和zone 文件

dannycat

dig 不出结果跟你自己的 DNS 服务器没有关系，除非你配置了自己使用自己的DNS。

看看你的 /etc/resolv.conf 用的是哪里的 DNS 服务器，或者使用命令[code:1] dig @ISP的DNS地址[/code:1]
