DNS 服务器不工作

DNS 服务器不工作

我想运行 DNS 服务器用于学习目的，但我不断收到此错误消息。你能帮忙吗？ （virtualbox 中的虚拟机：eth0 - NAT，eth1 - 内部适配器）

debianserver@debianserver:~$ sudo /etc/init.d/bind9 restart

文件/etc/bind/db.tanulas：

debianserver    IN      HINFO   Linux/Jessie

win8    IN      A       192.0.2.3

已编辑文件列表（按照老师的指示）：/etc/bind/named.conf.local, /etc/bind/db.tanulas, /etc/bind/db.2.0.192,/etc/resolv.conf

顺便说一句，/etc/resolv.conf每次重新启动后总是会被我的主机的机器名称服务器覆盖。为什么？它应该包含

search tanulas.hu 
nameserver 192.0.2.5

但事实并非如此。

# Generated by NetworkManager
nameserver 84.2.46.1
nameserver 84.2.44.1

这是对 DNS 服务器的查询。

debianserver@debianserver:~$ dig @localhost tanulas.hu

nslookup对于 debianserver 最终连接超时。

如果算数，则udhcpd可以正常工作。

谢谢

HINFO 必须有 2 个参数：“CPU/硬件”和“操作系统”。你只有一个。尝试扩展它：

debianserver IN HINFO Linux/Jessie makosteszta
