1，下载源码： ，选中 dhcp-3.1.3.tar.gz；
2，解压 tar -zxvf dhcp-3.1.3.tar.gz，然后进入./dhcp-3.1.3/，运行配置./configure，之后生成work.linux-2.2文件夹,进入work.linux-2.2/client/，输入make "CC=arm-linux-gcc -static"，将编译生成dhclient。
3，拷贝生成的dhclient到mini2440开发板上，为方便使用，可以放在/usr/bin/下；拷贝另外两个配置文件到开发板，分别是
/dhcp-3.1.3/client/dhclient.conf和/dhcp-3.1.3/client/scripts/linux 到开发板的/sbin/目录下。并改名后一个文件为dhclient-script，并修改该文件的第一行#! /bin/bash 为#! /bin/sh，保存后，修改权限 chmod +x /sbin/dhclient-script。
4，为eth0 或者wlan0配置dhcp服务，输入dhclient eth0 或者dhclient wlan0 即可，得到如下信息：
eth0:
