dhcp版本: 3.1.3

ARM 开发板:OK6410 

Linux内核2.6.28 或3.0.1

 

1 下载源码:http://download.csdn.net/detail/lanyang123456/4147066 或者http://gd.tuwien.ac.at/infosys/servers/isc/dhcp/  或者https://www.isc.org/software/dhcp/

2  解压并编译

tar -zxvf dhcp-3.1.3.tar.gz,然后进入dhcp-3.1.3。目录,运行配置./configure,成功之后生成work.linux-2.2文件夹, 进入work.linux-2.2/client目录,

输入make "CC=/usr/local/arm/4.2.2-eabi/arm-linux-gcc -static",编译生成dhclient。

其中CC=/usr/local/arm/4.2.2-eabi/arm-linux-gcc 为交叉编译器的路径

 

3 移植到开发板。

拷贝生成的dhclient到OK6410开发板上,为方便使用,可以放在/usr/bin/下.

 

拷贝配置文件dhcp-3.1.3/client/dhclient.conf和/dhcp-3.1.3/client/scripts/linux 到开发板的/sbin/目录下,并将后一个文件重命名为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。

 

运行命令

#dhclient wlan0

针对问题

在/var目录下创建state目录,再在state目录下创建dhcp目录

#mkdir /var/state

#mkdir /var/state/dhcp

 

 

再次运行dhclient

                 <*> Packet socket                        

                 [*]   Packet socket: mmapped IO

 

添加 socket filter支持

[*] Networking support  ---> 

        Networking options  --->

                 [*] Network packet filtering framework (Netfilter)  --->

                         --- Network packet filtering framework (Netfilter)               

                           [ ]   Network packet filtering debugging (NEW)                   

                            [*]   Advanced netfilter configuration (NEW)
