成功移植DHCP客户端到mini2440，已OK！

更新原贴，此贴已经验证： 1，下载源码：http://gd.tuwien.ac.at/infosys/servers/isc/dhcp/ ，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: 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 DHCPOFFER from 192.168.1.1 DHCPACK from 192.168.1.1 bound to 192.168.1.108 -- renewal in 40380 seconds. wlan0: Internet Systems Consortium DHCP Client V3.1.3 Copyright 2004-2009 Internet Systems Consortium.
