This method entails defining a pool (sometimes also called a range or scope) of IP addresses from which DHCP clients are supplied their configuration properties dynamically and on a fist come first serve basis. When a DHCP client is no longer on the network for a specified period, the configuration is expired and released back to the address pool for use by other DHCP Clients.

该模式需要定义一个 IP 地址池 (有时也叫范围或作用域) ，以便 DHCP 客户端可以被动态提供它们的配置from which DHCP clients are supplied their configuration properties dynamically and on a fist come first serve basis。当一个 DHCP 客户端有段时间不再在网络上时，该配置将过期并释放回地址池以便为其他 DHCP 客户端使用。

Ubuntu is shipped with both DHCP server and client. The server is <application>dhcpd</application> (dynamic host configuration protocol daemon). The client provided with Ubuntu is <application>dhclient</application> and should be installed on all computers required to be automatically configured. Both programs are easy to install and configure and will be automatically started at system boot.

ubuntu 提供 DHCP 服务器及其客户端。服务器叫 <application>dhcpd</application> (动态主机配置协议守护程序)。Ubuntu 提供的客户端叫 <application>dhclient</application>，应该安装在所有自动配置的计算机上。这两个程序很容易安装和配置，并可在系统引导时自动启用。

Please note that if you are installing the DHCP server for the first
time you need to configure. Please stop (/etc/init.d/dhcp
stop) the DHCP server daemon, edit /etc/dhcpd.conf to suit your needs
and particular configuration, and restart the DHCP server daemon
(/etc/init.d/dhcp start).
You also need to edit /etc/default/dhcp to specify the interfaces dhcpd
should listen to. By default it listens to eth0.
NOTE: dhcpd's messages are being sent to syslog. Look there for
diagnostics messages.
Starting DHCP server: dhcpd failed to start - check syslog for diagnostics. |
