我正在尝试用我的树莓派设置一个 DHCP 服务器，但是服务isc-dhcp 服务器無法啟動。
为什么不重新启动服务？
是否配置

# Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACES="eth1"
答案1
在中/etc/network/interfaces，您需要将 eth1 的节更改为如下形式
auto eth1
iface eth1 inet static
address 192.168.2.1
netmask 255.255.255.0
你似乎已经/etc/default/isc-dhcp-server掌握了
