DHCP 服务器未启动

Question

我在 ubuntu 服务器 11.04 中安装了 dhcp3-server

apt-get install dhcp3-server

但是，安装过程中出现错误消息：

当我想访问该文件时，/etc/dhcp3/dhcpd.conf我找不到它，但该软件包dhcp-server已安装。

Answer 1

尝试编辑/etc/dhcp/dhcpd.conf。它应该与 isc-dhcp-server 软件包以及依赖于它的 dhcp3-server 软件包一起安装。

$ dpkg -S dhcpd.conf
isc-dhcp-server: /usr/share/doc/isc-dhcp-server/examples/dhcpd.conf
isc-dhcp-server: /etc/dhcp/dhcpd.conf
isc-dhcp-server: /usr/share/man/man5/dhcpd.conf.5.gz

Answer 2

要运行 DHCP 服务器，您需要/etc/default/dhcp首先编辑该文件并设置活动网络接口列表。在这些接口上，DHCP 将为请求提供服务。然后，您必须通过编辑和添加适当的“子网”条目来配置服务器/etc/dhcp/dhcpd.conf。
