（加载驱动时，将文件权限更改为可读可写，并执行脚本）
把命令写入一个脚本：
add_remove_led.sh

!/bin/sh

if [ ACTION=“add”];thenechocreate/dev/ A C T I O N = “ a d d ” ] ; t h e n e c h o c r e a t e / d e v / $ACTION = “add” ]; then echo create /dev/$MDEV > /dev/console;

1. Udev 脚本学习:
   mdev.conf的格式：

USB-WIFI调试:
1.配置内核:
make menuconfig, /CONFIG_ATH9K_HTC 得到下面信息
Symbol: ATH9K_HTC [=n] |
| Type : tristate |
| Prompt: Atheros HTC based wireless cards support |
| Defined at drivers/net/wireless/ath/ath9k/Kconfig:100 |
| Depends on: NETDEVICES [=y] && WLAN [=y] && ATH_COMMON [=n] && USB [=y] && MAC80211 [=m] |
| Location: |
| -> Device Drivers |
| -> Network device support (NETDEVICES [=y]) |
| -> Wireless LAN (WLAN [=y]) |
| -> Atheros Wireless Cards (ATH_COMMON [=n])

配置:
-> Networking suppor
-> Wireless
<*> cfg80211 - wireless configuration API
<*> Generic IEEE 802.11 Networking Stack (mac80211)
-> Device Drivers
-> Network device support
-> Wireless LAN
-> Atheros Wireless Cards
<*> Atheros HTC based wireless cards support
make uImage

把固件htc_9271.fw放到开发板/lib/firmware
Cp htc_9271.fw /home/book/work/rootfs_min/lib/firmware

2.安装iw 工具
2.1 安装iw依赖的 libnl库
tar xzf libnl-3.2.23.tar.gz
cd libnl-3.2.23/
./configure –host=arm-linux –prefix=$PWD/tmp
修改 lib/addr.c 添加宏(宏来自内核源码)
make
make install

把编译出来的头文件应该放入：
/usr/arm-linux-gnueabihf-gcc/include
cd tmp/include/libnl3
sudo cp netlink -rf /usr/local/arm/4.3.2/arm-none-linux-gnueabi/libc/usr/include

把编译出来的库文件应该放入：

把编译出来的库文件应该放入NFS文件系统的lib目录：

2.2 编译 iw 工具
获取iw工具
可以从.0.tar.gz
Makefile中定义了PKG_CONFIG_PATH，路径指向libnl库
export PKG_CONFIG_PATH=/home/book/work/software/wifi_source/01.iw/libnl-3.2.23/temp/lib/pkgconfig:$PKG_CONFIG_PATH
make CC=arm-linux-gnueabihf-gcc

iw list // 列出WIFI网卡的性能
iw dev wlan0 scan // 扫描WIFI AP
iw wlan0 connect dswei // 连接到WIFI AP：dswei (open)
iw wlan0 connect dswei keys d:0:baiwenwang123 // 连接到WIFI AP：dswei (WEP)
d: default, 0: 第0个密码
3.编译wpa_supplicant :
可用于上述4种”认证/加密”
3.1 先编译它的依赖libopenssl
tar xzf openssl-1.0.1d.tar.gz
cd openssl-1.0.1d/
./config shared no-asm –prefix= PWD/tmp修改Makefile:CC=arm−linux−gccAR=arm−linux−ar P W D / t m p 修 改 M a k e f i l e : C C = a r m − l i n u x − g c c A R = a r m − l i n u x − a r $PWD/tmp 修改Makefile: CC= arm-linux-gcc AR= arm-linux-ar$(ARFLAGS) r
RANLIB= arm-linux-ranlib
NM= arm-linux-nm
MAKEDEPPROG= arm-linux-gcc

make
make install

3.2 编译wpa_supplicant
要有一个配置文件.config
tar xzf wpa_supplicant-2.0.tar.gz
cd wpa_supplicant-2.0/wpa_supplicant/
cp defconfig .config
修改.config加上一行: CONFIG_LIBNL32=y
修改Makefile:
CC=arm-linux-gcc

编译出错提示 找不到 ssl.h
Makefile 增加一行 CFLAGS += -I/usr/arm-linux-gnueabihf/include/
make
make DESTDIR=$PWD/tmp install
把 wpa_cli wpa_passphrase wpa_supplicant 复制到 文件系统的sbin目录中。
文件系统中创建文件夹 mkdir -p /var/run/wpa_supplicant

（使用: 在examples 目录中有很多的配置文件，可用于open wep wep2 参考
book@ubuntu:~/work/software/wifi_source/02.wpa_supplicant/wpa_supplicant-2.0/wpa_supplicant/examples$ ls *.conf -l
-rw-rw-r– 1 book book 269 Jan 12 2013 ieee8021x.conf
-rw-rw-r– 1 book book 1144 Jan 12 2013 openCryptoki.conf
-rw-rw-r– 1 book book 133 Jan 12 2013 plaintext.conf
-rw-rw-r– 1 book book 2930 Jan 12 2013 udhcpd-p2p.conf
-rw-rw-r– 1 book book 170 Jan 12 2013 wep.conf
-rw-rw-r– 1 book book 284 Jan 12 2013 wpa2-eap-ccmp.conf
-rw-rw-r– 1 book book 181 Jan 12 2013 wpa-psk-tkip.conf ）

在文件系统的etc 文件夹中 新建一配置文件 wpa_wpa2.conf
ctrl_interface=/var/run/wpa_supplicant
network={
ssid=”dswei”
psk=”baiwenwang123”
}

配置文件内容解释:
ctrl_interface=/var/run/wpa_supplicant # 一个目录,用于wpa_supplicant和wpa_cli的socket通信
network={
ssid=”dswei”
proto=WPA # proto: list of accepted protocols, 可取WPA,RSN
# If not set, this defaults to: WPA RSN
key_mgmt=WPA-PSK # 认证方式
# If not set, this defaults to: WPA-PSK WPA-EAP
pairwise=TKIP # If not set, this defaults to: CCMP TKIP
group=TKIP # If not set, this defaults to: CCMP TKIP WEP104 WEP40

控制台执行
ifconfig wlan0 up
iw dev wlan0 scan // 扫描热点
wpa_supplicant -B -c/etc/wpa_wpa2.conf -iwlan0
wpa_cli -iwlan0 status // 查看状态

访问外网：
修改/etc/resolv.conf添加DNS:
nameserver 192.168.1.1

设置网关:
route add default gw 192.168.1.1

1. 编译 安装 Dhcp
   c.1 编译、安装
   tar xzf dhcp-4.2.5-P1.tar.gz
   cd dhcp-4.2.5-P1
   ./configure –host=arm-linux-gnueabihf ac_cv_file__dev_random=yes

cd bind
修改Makefile:
./configure BUILD_CC=gcc ac_cv_file__dev_random=yes –host=arm-linux-gnueabihf –disable-kqueue

tar xzf bind.tar.gz
cd bind-9.8.4-P2
修改 lib/export/dns/Makefile.in
gen: srcdir/gen.c s r c d i r / g e n . c ${srcdir}/gen.c${CC} ALLCFLAGS A L L C F L A G S ${ALL_CFLAGS}${LDFLAGS} -o @ @ $@${srcdir}/gen.c LIBS改为gen: L I B S 改 为 g e n : ${LIBS} 改为 gen:${srcdir}/gen.c
BUILDCC B U I L D C C ${BUILD_CC}${ALL_CFLAGS} LDFLAGS−o L D F L A G S − o ${LDFLAGS} -o$@ srcdir/gen.c s r c d i r / g e n . c ${srcdir}/gen.c${LIBS}

cd ../..
make DESTDIR=$PWD/tmp install

把文件复制到NFS
sudo cp bin/* /work/nfs_root/fs_mini_mdev_new/bin/
sudo cp sbin/* /work/nfs_root/fs_mini_mdev_new/sbin/
sudo cp etc/dhclient.conf.example //work/nfs_root/fs_mini_mdev_new/etc/dhclient.conf
sudo cp etc/dhcpd.conf.example //work/nfs_root/fs_mini_mdev_new/etc/dhcpd.conf

sudo cp client/scripts/linux /work/nfs_root/fs_mini_mdev_new/etc/dhclient-script
chmod +x /work/nfs_root/fs_mini_mdev_new/etc/dhclient-script
并修改

!/bin/bash

改为

!/bin/sh

命令:
dhclient wlan0 连上AP 后自动非配ip 和 路由
5.AR9271 驱动模块的编译:
对于包含了AR9271网卡驱动的内核，有一个问题：
在上电之前就接上了网卡，那么系统启动后无法识别出这个网卡。
解决方法：
1．上电后再接网卡
2．把驱动编译为模块，当系统启动后再insmod： 可以在上电之前就接网卡

可能原因：ath9k_htc.ko要用到固件, 但是固件要到根文件系统被挂载后才能访问
将 Atheros HTC based wireless cards support 编译成模块
DEVICES DRIVER
NETWORK device support
Wireles LAN
Atheros Wireless Cards
Atheros HTC based wireless cards support

 编译内核 make uImage编译模块 make modules cp drivers/net/wireless/ath/ath9k/*.ko  文件 copy 到文件系统中.init.d/rcs中脚本增加如下命令 :insmod ath9k_hw.koinsmod ath9k_common.koinsmod ath9k_htc.ko

写脚本，利用mdev使一接入WIFI网卡，就自动执行wpa_supplicant等
cat /etc/mdev.conf
wlan0 0:0 777 * /sbin/auto_wifi.sh

cat /sbin/auto_wifi.sh

!/bin/sh

if [ $ACTION = “add” ];
then
wpa_supplicant -B -c/etc/wpa_wpa2.conf -iwlan0
wpa_cli -a/sbin/wpa_action.sh -B
else
killall wpa_supplicant
killall wpa_cli
killall dhclient
fi

chmod +x /sbin/auto_wifi.sh

一连接上WIFI AP, 就自动执行dhclient

创建一脚本:
cat /sbin/wpa_action.sh

!/bin/sh

IFNAME= 1CMD= 1 C M D = $1 CMD=$2
if [ “ CMD”=“CONNECTED”];thenechoconnect C M D ” = “ C O N N E C T E D ” ] ; t h e n e c h o c o n n e c t $CMD” = “CONNECTED” ]; then echo connect$IFNAME, dhclient for it > /dev/console
dhclient IFNAMEfiif[“ I F N A M E f i i f [ “ $IFNAME fi if [ “$CMD” = “DISCONNECTED” ]; then
echo disconnect $IFNAME, kill dhclient for it > /dev/console
killall dhclient
fi

chmod +x /sbin/wpa_action.sh

1. Wpa_cli 常用命令

iw list // 列出WIFI网卡的性能
iw dev wlan0 scan // 扫描WIFI AP
iw wlan0 connect dswei // 连接到WIFI AP：dswei (open)
iw wlan0 connect dswei keys d:0:baiwenwang123 // 连接到WIFI AP：dswei (WEP)
d: default, 0: 第0个密码

wpa_supplicant -B -c/etc/wpa_wpa2.conf -iwlan0 //-B 后台执行 -c执行脚本 -d 调试信息 /etc/wpa_wpa2.conf
wpa_cli -iwlan0 status // 查看状态

连接WPA-PSK/WPA2-PSK加密的AP
　　>add_network (假设返回2)
　　>set_network 2 ssid “dswei”
　　>set_network 2 psk “baiwenwang123”
　　>enable_network 2

list_networks //列出配置文件中的网络
scan_results // 列出扫描到的wifi网络

7.Wifi 程序测试：
用以前的 server 、client程序，
Wifi 连接到tp-link路由， 关掉eth0 eth1网卡
Arm板 执行客户端： ./cli 192.168.1.199
Pc ubuntu 执行服务器 : ./ser
