一、下载源码：
在 ,选中
dhcp-3.1-ESV-R3.tar.gz。
二、配置、编译
(1)解压 tar -zxvf dhcp-3.1-ESV-R3.tar.gz，然后进入dhcp-3.1-ESV-R3/目录下，
运行配置./configure
之后生成work.linux-2.2文件夹,进入work.linux-2.2/目录
输入make "CC=arm-linux-gnu-gcc -static"
（在此静态编译，以免发生命令找不到。当然可以动态编译，只要和你的文件系统用的库一致）
将在dhcp-3.1-ESV-R3/work.linux-2.2/client目录下编译生成dhclient。
三、移植到开发板
(1)拷贝生成的dhclient到FS2410开发板上，为方便使用，可以放在/usr/bin/或/sbin目录下；
执行命令：cp dhclient
/rootfs/filesystem/sbin
拷贝另外两个配置文件到开发板，分别是/dhcp-3.1-ESV-R3/client/dhclient.conf
/dhcp-3.1-ESV-R3/client/scripts/linux
到开发板的/sbin/目录下。并改名后一个文件为dhclient-script
执行命令：cp dhclient.conf
/rootfs/filesystem/sbin
cp linux
/rootfs/filesystem/sbin/dhclient-script
(2)并修改dhclient-script该文件的第一行#!/bin/bash 为#!/bin/sh，
(3)保存后修改权限 rootfs/filesystem$sudo chmod +x /sbin/dhclient*
四、测试
为eth0 或者wlan0配置dhcp服务，输入dhclient eth0 或者dhclient wlan0 即可，得到如下类似信息：
eth0:
Listening on LPF/eth0/08:90:90:90:90:90
Sending on LPF/eth0/08:90:90:90:90:90
Sending on Socket/fallback
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
DHCPREQUEST on eth0 to 255.255.255.255 port 67
DHCPNAK from 192.168.1.1
eth0: link down
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3
receive_packet failed on eth0: Network is down
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
DHCPREQUEST on eth0 to 255.255.255.255 port 67
