isc-dhcp-server 计算机未接收 IP 地址

Question

我最初isc-dhcp-server在 Raspberry Pi 上运行直到我意外删除了/lib。我设法获得了/etc/dhcp/dhcpd.conf。我安装了isc-dhcp-server。sudo apt-get install isc-dhcp-server现在，如果我查看syslog，我会在日志中看到DHCPOFFER和DHCPDISCOVER，但计算机永远不会获得 IP。

例如，我看到了大约十几种不同的变体：

Mar 23 19:47:00 server dhcpd: No hostname for 192.168.0.118
Mar 23 19:47:00 server dhcpd: DHCPDISCOVER from 00:00:00:00:00:00 (client) via p1p1
Mar 23 19:47:00 server dhcpd: DHCPOFFER on 192.168.0.118 to 00:00:00:00:00:00 (box) via p1p1

偶尔我会看到这样的情况：

DHCPACK on 192.168.0.144 to 00:00:00:00:00:00 via p1p1

00:00:00:00:00:00 不是实际的 MAC 地址。

/etc/dhcp/dhcpd.conf是：
