linux 日志报错：error (unexpected RCODE REFUSED) resolving '

今天在机子上查看日志，偶然间发现了一堆错误。因为之前配置过DNS 和 squid，报错，之后查错，某度了一下，没找到答案。

下面是一点错误信息： 

Aug  8 11:40:30 host named[1668]: error (unexpected RCODE REFUSED) resolving ‘208.22.200.65.in-addr.arpa/PTR/IN‘: 74.115.231.45#53

在一个英文网站上，发现了点东西，如下：

Bind : Unexpected RCODE (REFUSED) resolving ‘xx.xx.xx.xx.in-addr.arpa/PTR/IN’

Experiencing this error in Bind logs?

named[xxxxxx]: unexpected RCODE (REFUSED) resolving ‘xx.xx.xx.xx.in-addr.arpa/PTR/IN’: xxx.xxx.xxx.xxx#53

This is probably because you have a forwarder in your named.conf that refuse your requests. Simply look at the end of the previous line : “xxx.xxx.xxx.xxx#53” and search this address in your named configuration file – it should be located inside the forwarders :

Shell

forwarders { xxx.xxx.xxx.xxx; };

1

forwarders { xxx.xxx.xxx.xxx; };

You need to remove or comment this host to get rid of the error in log or allow your host to query this server if it belongs to you!

Tip : To make sure the remote DNS server you are trying to query is refusing your request, you can try to DIG a host like this replacing the domain and IP to meet your situation :

Shell

dig domain.tld @xxx.xxx.xxx.xxx

1

dig domain.tld @xxx.xxx.xxx.xxx
