DIG：始终获得状态：FORMERR

Question

我在 ubuntu 18.04 下，有 DNS 问题，所以我使用dig命令来调试我的 DNS。

事情是，当我挖掘像 的站点redhat.com或我的配置良好的 DNS 时，我总是得到一个FORMERR状态，而且似乎SERVER总是设置为 127.0.0.1:53。

?  dig redhat.com                            

; <<>> DiG 9.11.3-1ubuntu1.5-Ubuntu <<>> redhat.com

Answer 1

我修复了它添加+noedns到命令：

$ dig +noedns redhat.com  

; <<>> DiG 9.11.3-1ubuntu1.5-Ubuntu <<>> +noedns redhat.com
;; global options: +cmd
;; Got answer:
