wpa_supplicant无线网络配置

家里用的是mecury的路由器,我的是rhel6.3-x64系统,设置无线路由上网

最简单的方法是 使用NetworkManager服务,如果不想使用的话,按照下面的方法也可以。

路由设置的网段是192.168.1.X/24,路由加密方法是wpa

一.临时设置上网,证明以下的步骤可行

1.设置ip

ifconfig wlan0 192.168.1.xxx

2.设置路由

route add default gw 192.168.1.1

3.设置dns

vim /etc/resolv.conf

nameserver 192.168.1.1

4.修改/etc/wpa_supplicant/wpa_supplicant.conf

添加

network={

     ssid="  ssid的名字"

    psk=" 密码 "

}

执行命令wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

 

二.如果以上方法可行,修改成开机自动连上无线路由

设置成开机自动连上路由上网方法:

1.修改/etc/sysconfig/network-scripts/ifcfg-wlan0

IPADDR=192.168.1.xxx

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

2.修改/etc/wpa_supplicant/wpa_supplicant.conf

添加

network={

     ssid="  ssid的名字"

    psk=" 密码 "

}

3.修改/etc/rc.local

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

 

三.利用NetworkManager这个服务,设置无线路由上网

    目前可以使用wireless-tools 或wpa_supplicant工具来配置无线网络。请记住重要的一点是,对无线网络的配置是全局性的,而非针对具体的接口。

   wpa_supplicant是一个较好的选择,但缺点是它不支持所有的驱动。请浏览wpa_supplicant网站获得它所支持的驱动列表。另外,wpa_supplicant目前只能连接到那些你已经配置好ESSID的无线网络。wireless-tools支持几乎所有的无线网卡和驱动,但它不能连接到那些只支持WPA的AP。

    经过编译后的wpa_supplicant源程序可以看到两个主要的可执行工具:wpa_supplicant和wpa_cli。wpa_supplicant是核心程序,它和wpa_cli的关系就是服务和客户端的关系:后台运行wpa_supplicant,使用wpa_cli来搜索、设置、和连接网络。

       如何用wpa_supplicant使能一个wifi连接?

Step by step:

1、运行wpa_supplicant程序;

执行:/system/bin/wpa_supplicant -d -Dwext -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf

其中:

-d :增加调试信息

-Dwext :wext,驱动名称

-iwlan0 :wlan0,网络接口名称

/system/bin/wpa_supplicant :wpa_supplicant可执行程序path

/data/misc/wifi/wpa_supplicant.conf :wpa_supplicant的配置文件path

2、运行命令行工具wpa_cli ;

执行 :wpa_cli -iwlan0 -p/data/system/wpa_supplicant

注,-p/data/system/wpa_supplicant中的wpa_supplicant并不是可执行程序,而是个控制套接字。

此时会进入交互模式。其中交互模式的命令如下表:

Full command

Short command

Description

status

stat

displays the current connection status

disconnect

disc

prevents wpa_supplicant from connecting to any access point

quit

q

exits wpa_cli

terminate

term

kills wpa_supplicant

reconfigure

recon

reloads wpa_supplicant with the configuration file supplied (-c parameter)

scan

scan

scans for available access points (only scans it, doesn't display anything)

scan_result

scan_r

displays the results of the last scan

list_networks

list_n

displays a list of configured networks and their status (active or not, enabled or disabled)

select_network

select_n

select a network among those defined to initiate a connection (ie select_network 0)

enable_network

enable_n

makes a configured network available for selection (ie enable_network 0)

disable_network

disable_n

makes a configured network unavailable for selection (ie disable_network 0)

remove_network

remove_n

removes a network and its configuration from the list (ie remove_network 0)

add_network

add_n

adds a new network to the list. Its id will be created automatically

set_network

set_n

shows a very short list of available options to configure a network when supplied with no parameters.

See next section for a list of extremely useful parameters to be used with set_network and get_network.

get_network

get_n

displays the required parameter for the specified network. See next section for a list of parameters

save_config

save_c

saves the configuration


设置网络的基本格式:set_network []

显示网络信息的基本格式:get_network

相应的参数如下表:

Key

Description

Parameters

ssid

Access point name

string

id_str

String identifying the network

string

priority

Connection priority over other APs

number (0 being the default low priority)

bssid

Mac address of the access point

mac address

scan_ssid

Enable/disbale ssid scan

0, 1, 2

key_mgmt

Type of key management

WPA-PSK, WPA_EAP, None

pairwise

Pairwise ciphers for WPA

CCMP, TKIP

group=TKIP

Group ciphers for WPA

CCMP, TKIP, WEP104, WEP40

psk

Pre-Shared Key (clear or encrypted)

string

wep_key0

WEP key (up to 4: wep_key[0123])

string

eap

Extensible Authentication Protocol

MD5, MSCHAPV2, OTP, GTC, TLS, PEAP, TTLS

identity

EAP identity string

string

password

EAP password

string

ca_cert

Pathname to CA certificate file

/full/path/to/certificate

client_cert

Pathname to client certificate

/full/path/to/certificate (PEM/DER)

private_key

Pathname to a client private key file

/full/path/to/private_key (PEM/DER/PFX)

eg.1、连接无加密的AP

>add_network  (It will display a network id for you, assume it returns 0)

>set_network 0 ssid "666"

>set_network 0 key_mgmt NONE

>enable_network 0

>quit

eg.2、连接WEP加密AP

>add_network   (assume return 1)

>set_network 1 ssid "666"

>set_network 1 key_mgmt NONE

>set_network 1 wep_key0 "your ap password"

>enable_network 1

eg.3、连接WPA-PSK/WPA2-PSK加密的AP

>add_network   (assume return 2)

>set_network 2 ssid "666"

>set_network 2 psk "your pre-shared key"

>enable_network 2

到此,wifi模块就能连接上AP了。

3、以上是通过命令行工具wpa_cli来实现wifi网络的连接。当然,也可以通过wpa_supplicant的配置文件来实现连接。

再回顾下运行wpa_supplicant时执行的命令:

/system/bin/wpa_supplicant -d -Dwext -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf

我们在执行时加上了-c/data/misc/wifi/wpa_supplicant.conf,我们可以将我们要连接的AP的设置以一定的格式写入wpa_supplicant.conf配置文件中即可。

eg. 

ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system update_config=1

network={

ssid="my access point"

proto=WPA

key_mgmt=WPA-PSK

psk="you pass words"

}

具体格式可参考:http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob_plain;f=wpa_supplicant/wpa_supplicant.conf
