編者按：本文是一篇無線網絡技術應用文章，告訴大家如何在Linux下面配置wpa客戶端。
內核:
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 #
網卡:
bt tools # lspci -vv |grep -i 394
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
bt tools #
操作系統版本:
bt tools # cat /etc/slax-version
SLAX 6.0.0
bt tools #
802.1x 客戶端版本:
bt ~ # wpa_supplicant -v
wpa_supplicant v0.5.7
Copyright (c) 2003-2006, Jouni Malinen and contributors
bt ~ #
bt tools #
配置文件內容: wpa 方式
bt ~ # cat /etc/wpa_supplicant.conf
network={
ssid="youssid"
psk="youpassword"
}
bt ~ #
命令以及參數:
命令:wpa_supplicant
使用參數:
-B = run daemon in the background
-c = Configuration file
-i = interface name
命令執行例子:
wpa_supplicant -B -ieth0 -c /etc/wpa_supplicant.conf
獲得地址:
dhcpcd eth0
察看網卡狀態以及參數:
bt ~ # iwconfig eth0
eth0 IEEE 802.11g ESSID:"youssid"

Link Quality=74/100 Signal level=-57 dBm Noise level=-57 dBm
Rx invalid nwid:0 Rx invalid crypt:1 Rx invalid frag:0

bt ~ # ifconfig eth0
eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx

這樣linux就可以使用wpa 訪問無線網絡了.要比wep好一些.
