基于FS2410的DHCP移植

一、下载源码：
在http://gd.tuwien.ac.at/infosys/servers/isc/dhcp/ ,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/，
home/dhcp/dhcp-3.1-ESV-R3$
运行配置./configure
home/dhcp/dhcp-3.1-ESV-R3$./configure
之后生成work.linux-2.2文件夹,进入work.linux-2.2/目录
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$
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）
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$make "CC=arm-linux-gnu-gcc -static"
将在dhcp-3.1-ESV-R3/work.linux-2.2/client目录下编译生成dhclient。 三、移植到开发板
（1）拷贝生成的dhclient到FS2410开发板上，为方便使用，可以放在/usr/bin/或/sbin目录下；
dhcp-3.1-ESV-R3/work.linux-2.2/client$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
home/dhcp/dhcp-3.1-ESV-R3/client$cp dhclient.conf /rootfs/filesystem/sbin
home/dhcp/dhcp-3.1-ESV-R3/client/scripts$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
