DHCP服务器可以用于动态分配IP，还可以结合TFTP服务器用于网络安装服务器，用于安装支持PXE的客户端。

安装

$ sudo apt-get install dhcp3-server

地方性的发现对方似懂非懂色

配置

DHCP服务器的配置为 /etc/dhcp3/dhcpd.conf

一个示例配置文件：

ddns-update-style none;

#deny unknown-clients;

# only listen on eth1
local-address 192.168.168.30;

# option definitions common to all supported networks...
option domain-name "china.nsn-net.net";
option domain-name-servers 10.159.195.10,10.159.208.5,10.159.192.10;

default-lease-time 6000;
max-lease-time 72000;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;


subnet 192.168.168.0 netmask 255.255.255.0 {
allow booting;
allow bootp;
interface br0;
default-lease-time 72000;
max-lease-time 144000;
option domain-name "china.nsn-net.net";
option domain-name-servers 10.159.195.10,10.159.208.5,10.159.192.10;

# WINS server
option netbios-name-servers 10.160.244.90,10.160.244.89;

# bootp: used for network install
