时间：2010-11-20 来源：mydear
Linux最近几年发展迅速，很多人舍弃微软应用Linux操作系统，Linux的强大功能是那么吸引人。这里介绍一些Linux知识，今天讲解Linux配置wpa客户端步骤，望你能学会Linux配置wpa。
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 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
以上就是Linux配置wpa的方法，这样Linux就可以使用wpa访问无线网络了.要比wep好一些.
