wpa_supplicant的用法

 

1. 命令格式：

   wpa_supplicant [-BddhKLqqstuvW] [-P<pid file>] [-g<global ctrl>] \

           -i<ifname> -c<config file> [-C<ctrl>] [-D<driver>] [-p<driver_param>] \

           [-b<br_ifname>] [-f<debug file>] \

           [-o<override driver>] [-O<override ctrl>] \

           [-N -i<ifname> -c<conf> [-C<ctrl>] [-D<driver>] \

           [-p<driver_param>] [-b<br_ifname>] ...]

2. 驱动（一般常使用的就是wext）：

     wext = Linux wireless extensions (generic)

     hostap = Host AP driver (Intersil Prism2/2.5/3)

     atmel = ATMEL AT76C5XXx (USB, PCMCIA)

     wired = Wired Ethernet driver

3. 各个选项及其含义:

     -b = optional bridge interface name

          增加网桥名称

    

     -B = run daemon in the background

          后台执行

    

     -c = Configuration file

          附加配置文件，即根据配置文件执行操作

    

     -C = ctrl_interface parameter (only used if -c is not)

          控制网口参数

    

     -i = interface name

          网口名称

    

     -d = increase debugging verbosity (-dd even more)

          增加调试信息输出

    

     -D = driver name (can be multiple drivers: nl80211,wext)

          驱动名称

    

     -g = global ctrl_interface

          全局网口配置

    

     -K = include keys (passwords, etc.) in debug output

          在debug输出中包含keys

    

     -t = include timestamp in debug messages

          将各个debug信息前输出时间标签

    

     -h = show this help text

          显示帮助信息

    

     -L = show license (GPL and BSD)

          显示license

    

     -o = override driver parameter for new interfaces

          覆盖driver参数

    

     -O = override ctrl_interface parameter for new interfaces

          覆盖ctrl_interface参数

    

     -p = driver parameters

          携带驱动参数

    

     -P = PID file

          进程文件

    

     -q = decrease debugging verbosity (-qq even less)

           在debug中不输出指定参数

    

     -v = show version

          显示版本信息

    

     -W = wait for a control interface monitor before starting

          启动前等待控制接口

    

     -N = start describing new interface

          启动对新接口的描述

4. 命令举例：

   wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

   网络接口为wlan0，读取文件为/etc/wpa_supplicant/wpa_supplicant.conf，执行无线配置
