綁定DNS伺服器

enter code here我正在設定我的主 DNS 伺服器。反向查找似乎運作正常，正向查找似乎是問題所在。

這是我的設定檔。

/etc/default/bind9:

RESOLVCONF=no
OPTIONS="-u bind -4"

/etc/bind/named.conf.options:

acl "trusted" { 192.168.1.0; localhost; };
options {
    directory "/var/cache/bind";
    recursion yes;
    allow-recursion { trusted; };
    listen-on { 192.168.1.204; 127.0.0.1; };
    allow-transfer { none; };
    forwarders { 
        192.168.1.254;
    };
// listen-on-v6 { any; };
};

/etc/bind/named.conf.local:

zone "example.home.local" {
    type master;
    file "etc/bind/zones/db.example.home.local";
    };

zone "1.168.192.in-addr.arpa" {
    type master;
    file "/etc/bind/zones/db.1.168.192";
    };

/etc/bind/zones/db.example.home.local:

;
; BIND data file for local loopback interface
;
$TTL    604800
@   IN  SOA ubuntuserver.example.home.local. root.example.home.local. (
                 14     ; Serial
             604800     ; Refresh
              86400     ; Retry
            2419200     ; Expire
             604800 )   ; Negative Cache TTL
;
;name servers - NS records
@   IN  NS  ubuntuserver.example.home.local.

;name servers - A records
ubuntuserver    IN  A   192.168.1.204

;subnet - A records
ubuntuweb   IN  A   192.168.1.208

/etc/bind/zones/db.1.168.192:

;
; BIND reverse data file for local loopback interface
;
$TTL    604800
@   IN  SOA example.home.local. root.example.home.local. (
                 11     ; Serial
             604800     ; Refresh
              86400     ; Retry
            2419200     ; Expire
             604800 )   ; Negative Cache TTL
; name servers
@   IN  NS  UbuntuServer.

; PTR records
204 IN  PTR ubuntuserver.example.home.local.
208 IN  PTR ubuntuweb.example.home.local.

如前面提到的，反向查找工作得很好。當我跑步時

sudo named-checkzone 1.168.192.in-addr.arpa /etc/bind/zones/db.1.168.192

結果沒問題，而且當我nslookup從測試客戶端執行操作時，它能夠成功地將 IP 位址解析為名稱。

然而，當我跑步時

sudo named-checkzone example.home.local /etc/bind/zones/db.example.home.local

它報告回來

loading from master file /etc/bind/zones/db.example.home.local failed: unknown class/type

答案1

您有一個拼字錯誤，/etc/bind/named.conf.local缺少/資料庫路徑的前導：

file "etc/bind/zones/db.example.home.local";
