DNS 伺服器不工作

我想為學習目的執行 DNS 伺服器，但我不斷收到此錯誤消息。你能幫忙嗎？（virtualbox中的虛擬機：eth0 - NAT，eth1 - 內部適配器）

debianserver@debianserver:~$ sudo /etc/init.d/bind9 restart
[ ok ] Restarting bind9 (via systemctl): bind9.service.

文件/etc/bind/db.tanulas：

debianserver    IN      HINFO   Linux/Jessie

win8    IN      A       192.0.2.3

已編輯文件列表（按照老師的指示）：/etc/bind/named.conf.local, /etc/bind/db.tanulas, /etc/bind/db.2.0.192,/etc/resolv.conf

順便說一句/etc/resolv.conf，每次重新啟動後總是被我主機的機器名稱伺服器覆蓋。為什麼？它應該包含

search tanulas.hu 
nameserver 192.0.2.5

但事實並非如此。

# Generated by NetworkManager
nameserver 84.2.46.1
nameserver 84.2.44.1

這是對 DNS 伺服器的查詢。

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

; <<>> DiG 9.9.5-9+deb8u6-Debian <<>> @localhost tanulas.hu

nslookup對於 debianserver 以連接超時結束。

如果它很重要，則udhcpd可以正常工作。

謝謝

HINFO 必須有 2 個參數：“CPU/硬體”和“OS”。你只有一個。嘗試擴展它：

debianserver IN HINFO Linux/Jessie makosteszta
