使用 nsupdate 时无法解析主 DNS

Question

我想使用 nsupdate 在本地 DNS 服务器上注册客户端（Raspbian GNU/Linux 8.0 jessie 4.1.19-v7+）

> nsupdate -d  
> update add lea02.example.local 600 a 10.132.34.32

服务器的响应在解析其自身名称时出现奇怪的失败：

Reply from SOA query:

Found zone name: example.local
The master is: srvns01.example.local
couldn't get address for 'srvns01.example.local': not found

但简单的 nslookup 并未表明这里存在问题：

> nslookup srvns01.example.local

Server:         10.132.34.71
Address:        10.132.34.71#53

Name:   srvns01.example.local
Address: 10.132.34.71
