BIND9 无法解析

出于某种原因，当我执行nslookup router或nslookup KLAMESERVER为我的 router.Klamenick.com 或 KLAMESERVER.Klamenick.com 内部域执行此操作时，它总是显示：

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

我检查了我配置的所有文档，以检查我的域名后面是否有句点，结果确实有。一定是别的原因。

以下是我配置的文件：

/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

有人知道发生什么事了吗？

答案1

我还没有研究细节，但问题出在这一行：

dnssec-validation auto;

看来 16.04 版的 bind9 默认启用了 dnssec-validation。切换到：

dnssec-validation no;

应该可以解决问题。
