DNS HOST XXXXX NOT FOUND:5(REFUSED)错误问题解惑

DNS服务端可以正常解析，客户端已经在/etc/resolv.conf文件中配置了对应的域名，IP，仍然报REFUSED错误；说明是请求被拒绝的问题。

错误代码：

[root@rac2 ~]# host www.sgcc.com
Host www.sgcc.com not found: 5(REFUSED)

通过查找资料发现只需要修改named.conf文件中的match-clients属性

view localhost_resolver {
        match-clients      { any; };
        match-destinations { any; };
        recursion yes;
        include "/etc/named.rfc1912.zones";
};

然后重启服务即可。

[root@mydb named]# service named restart
Stopping named: .[  OK  ]
Starting named: [  OK  ]

客户端也能正常解析了

[root@rac2 ~]# host www.sgcc.com
www.sgcc.com has address 192.168.49.11

[root@rac2 ~]# host 192.168.49.11
11.49.168.192.in-addr.arpa domain name pointer www.sgcc.com.
