BIND9 無法解析

BIND9 無法解析

由於某種原因，當我這樣做nslookup router或nslookup KLAMESERVER為我的 router.Klamenick.com 或 KLAMESERVER.Klamenick.com 內部網域時，它總是說：

Server:         192.168.0.2
Address:        192.168.0.2#53
** server can't find router.Klamenick.com: SERVFAIL

我檢查了我配置的所有文檔，以檢查我的網域後面是否有句點，而且確實如此。一定是別的東西。

以下是我配置的檔案：

/etc/bind/named.conf.options

options {
directory "/var/cache/bind";

// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk.  See http://www.kb.cert.org/vuls/id/800113

// If your ISP provided one or more IP addresses for stable 
// nameservers, you probably want to use them as forwarders.  
// Uncomment the following block, and insert the addresses replacing 
// the all-0's placeholder.

forwarders {
8.8.8.8;
8.8.8.4;
};

//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys.  See https://www.isc.org/bind-keys

auth-nxdomain no;    # conform to RFC1035

};

    file "/etc/bind/db.Klamenick.com";
    };

    type master;
    notify no;
    file "/etc/bind/db.192";
};

有人知道怎麼回事嗎？

我還沒研究過細節，但問題出在這一行：

dnssec-validation auto;

看來16.04中的bind9版本預設啟用了dnssec-validation。切換到：

dnssec-validation no;

應該可以解決問題。
