基於FS2410的DHCP移植

  一、下載源碼：
     在http://gd.tuwien.ac.at/infosys/servers/isc/dhcp/ ,選中 dhcp-3.1-ESV-R3.tar.gz。

二、配置、編譯
(1)解壓 tar -zxvf dhcp-3.1-ESV-R3.tar.gz，然後進入./dhcp-3.1-ESV-R3/，
home/dhcp/dhcp-3.1-ESV-R3$
回合組態./configure
home/dhcp/dhcp-3.1-ESV-R3$./configure
之後產生work.linux-2.2檔案夾,進入work.linux-2.2/目錄
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$
輸入make "CC=arm-linux-gnu-gcc -static" （在此靜態編譯，以免發生命令找不到。當然可以動態編譯，只要和你的檔案系統用的庫一致）
home/dhcp/dhcp-3.1-ESV-R3/work.linux-2.2$make "CC=arm-linux-gnu-gcc -static"
將在dhcp-3.1-ESV-R3/work.linux-2.2/client目錄下編譯產生dhclient。

三、移植到開發板
(1)拷貝產生的dhclient到FS2410開發板上，為方便使用，可以放在/usr/bin/或/sbin目錄下；
dhcp-3.1-ESV-R3/work.linux-2.2/client$cp dhclient /rootfs/filesystem/sbin
拷貝另外兩個設定檔到開發板，分別是/dhcp-3.1-ESV-R3/client/dhclient.conf
                                                                      /dhcp-3.1-ESV-R3/client/scripts/linux
到開發板的/sbin/目錄下。並改名後一個檔案為dhclient-script
home/dhcp/dhcp-3.1-ESV-R3/client$cp dhclient.conf /rootfs/filesystem/sbin
home/dhcp/dhcp-3.1-ESV-R3/client/scripts$cp linux /rootfs/filesystem/sbin/dhclient-script
(2)並修改dhclient-script該檔案的第一行#!/bin/bash 為#!/bin/sh，

(3)儲存後修改許可權 rootfs/filesystem$sudo chmod +x /sbin/dhclient*

四、測試
為eth0 或者wlan0配置dhcp服務，輸入dhclient eth0 或者dhclient wlan0 即可，得到如下類似資訊：

eth0:
