在linux下面配置wpa 客户端
内核:
bt tools # uname -a
Linux bt 2.6.20-BT-PwnSauce-NOSMP #3 Sat Feb 24 15:52:59 GMT 2007 i686 i686 i386 GNU/Linux
bt tools #
网卡:
bt tools # lspci -vv |grep -i 394
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
bt tools #
操作系统版本:
bt tools # cat /etc/slax-version
SLAX 6.0.0
bt tools #
802.1x 客户端版本:

bt ~ # wpa_supplicant -v
wpa_supplicant v0.5.7
Copyright (c) 2003-2006, Jouni Malinen <jkmaline@cc.hut.fi> and contributors
bt ~ #
bt tools #
配置文件内容: wpa 方式
bt ~ # cat /etc/wpa_supplicant.conf
network={
      ssid="youssid"
      psk="youpassword"
}
bt ~ #

命令以及参数:
命令:wpa_supplicant
使用参数:

-B = run daemon in the background
-c = Configuration file
-i = interface name
命令执行例子:
wpa_supplicant -B -ieth0 -c /etc/wpa_supplicant.conf
获得地址:
dhcpcd eth0
察看网卡状态以及参数:
bt ~ # iwconfig eth0
eth0    IEEE 802.11g  ESSID:"youssid"
      Mode:Managed  Frequency:2.462 GHz  Access Point: 00:00:00:00:00:00
      Bit Rate:54 Mb/s Tx-Power:14 dBm
      Retry limit:15 RTS thr:off Fragment thr:off
      Encryption key:xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx Security mode:open
      Power Management:off
      Link Quality=74/100  Signal level=-57 dBm  Noise level=-57 dBm
      Rx invalid nwid:0  Rx invalid crypt:1  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:21 Missed beacon:0

bt ~ # ifconfig eth0
eth0    Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
      inet addr:192.168.2.100  Bcast:192.168.2.255  Mask:255.255.255.0
      inet6 addr: fe80::218:deff:feb0:38e5/64 Scope:Link
      UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
      RX packets:33 errors:2 dropped:31 overruns:0 frame:0
      TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:1000
      RX bytes:11177 (10.9 KiB)  TX bytes:4324 (4.2 KiB)
      Interrupt:11 Base address:0x2000 Memory:edf00000-edf00fff

这样linux就可以使用wpa 访问无线网络了.要比wep好一些.
