ISC-DHCP 和 Bind9：反向映射的 DDNS 更新失敗 (NOTAUTH)

我將 isc-dhcp-server 與此配置一起使用/etc/dhcp/dhcpd.conf：

ddns-updates on;
ddns-update-style interim;
include "/etc/bind/rndc.key";
authoritative;
zone bat. {
 primary localhost;
 key rndc-key;
}
zone lan.bat. {
 primary localhost;
 key rndc-key;
}
zone wlan.bat. {
 primary localhost;
 key rndc-key;
}
zone 10.in-addr.arpa. {
 primary localhost;
 key rndc-key;
}
zone 50.10.in-addr.arpa. {
 primary localhost;
 key rndc-key;
}
zone 100.10.in-addr.arpa. {
 primary localhost;
 key rndc-key;
}
subnet 10.50.0.0 netmask 255.255.0.0 {
 range 10.50.100.100 10.50.100.199;
 interface eth0;
 option domain-name-servers 10.50.0.1;
 option domain-name "lan.bat";
 option domain-search "lan.bat", "bat", "wlan.bat";
 option routers 10.50.0.1;
 option broadcast-address 10.50.255.255;
 default-lease-time 600;
 max-lease-time 7200;
}
subnet 10.100.0.0 netmask 255.255.0.0 {
 range 10.100.100.100 10.100.100.199;
 interface wlan0;
 option domain-name-servers 10.100.0.1;
 option domain-name "wlan.bat";
 option domain-search "wlan.bat", "bat", "lan.bat";
 option routers 10.100.0.1;
 option broadcast-address 10.100.255.255;
 default-lease-time 600;
 max-lease-time 7200;
}

和 bind9 用這個/etc/bind/named.conf.local：

include "/etc/bind/rndc.key";

zone "bat" {
       type master;
       file "/etc/bind/zones/db.bat.zone";
       notify yes;
       allow-update { key rndc-key; };
};

zone "lan.bat" {
       type master;
       file "/etc/bind/zones/db.lan.bat.zone";
       notify yes;
       allow-update { key rndc-key; };
};

zone "wlan.bat" {
       type master;
       file "/etc/bind/zones/db.wlan.bat.zone";
       notify yes;
       allow-update { key rndc-key; };
};

zone "10.in-addr-arpa" {
       type master;
       file "/etc/bind/zones/db.rev.10.in-addr-arpa.zone";
       allow-update { key rndc-key; };
};

zone "50.10.in-addr-arpa" {
       type master;
       file "/etc/bind/zones/db.rev.50.10.in-addr-arpa.zone";
       allow-update { key rndc-key; };
};

zone "100.10.in-addr-arpa" {
       type master;
       file "/etc/bind/zones/db.rev.100.10.in-addr-arpa.zone";
       allow-update { key rndc-key; };
};

當我與客戶端重新連接以選擇新 IP 時，我的系統日誌說：

從我的搜尋中，我了解到來自命名的消息update failed: not authoritative for update zone (NOTAUTH)指向不權威的 DHCP 伺服器。即使我相信已經發現了問題（如果我錯了，請告訴我），我無法修復它。所以我的問題是：如何配置 dhcp/bind 以獲得反向映射？

BIND 配置中的區域拼寫錯誤，例如，50.10.in-addr-arpa而不是50.10.in-addr.arpa.

此外，您應該考慮為此目的創建一個單獨的 TSIG 密鑰，而不是rndc在完全不同的上下文中濫用該密鑰。
