![isc-dhcp-server:dhcp动态更新dns记录](https://linux22.com/image/980019/isc-dhcp-server%EF%BC%9Adhcp%E5%8A%A8%E6%80%81%E6%9B%B4%E6%96%B0dns%E8%AE%B0%E5%BD%95.png)
当 DHCP 提供地址时,我尝试动态更新 DNS 记录。但即使我在 /etc/bind/named.conf.local 中使用密钥指定了 allow-update,并在 /etc/dhcp/dhcpd.conf 中指定了相同的密钥,访问仍被拒绝并且超时。我还尝试在 allow update 中设置一个 ip 地址,但这似乎也不起作用。是不是我忘记在这里添加什么了?

我很感激任何答案:)
