安裝

安裝net-wireless/wpa_supplicant包

emerge --ask wpa_supplicant

配置

Set for Gentoo net.* scrips，tell the network script to use wpa_supplicant.
File/etc/conf.d/net

modules_wlan0="wpa_supplicant"
# 因爲wpa_supplicant還不能很好的自動偵測驅動，所以需要我們爲其指定正在使用的驅動。
wpa_supplicant_wlan0="-Dnl80211"
config_wlan0="dhcp"

/etc/wpa_supplicant/wpa_supplicant.conf

# Allow users in the 'wheel' group to control wpa_supplicant
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
# Make this file writable for wpa_gui
update_config=1
#自動掃描AP（也就是可以上的無線網絡熱點）
ap_scan=1   
# 簡單的情形：WPA-PSk密碼驗證方式，PSK是ASCII密碼短語，所有合法的加密方式都允許連接
network={
  ssid="simple"
  psk="very secret passphrase"
  # 優先級越高，就能越早匹配到。
  priority=5
}

也可以使用wpa_passphrase命令添加無線熱點

wpa_passphrase [ ssid ] [ passphrase ] >> /etc/wpa_supplicant/wpa_supplicant.conf

上面這條命令可以自動生成一段配置，我們將它輸出添加到 wpa_supplicant 的默認配置文件裏面。

啓動網絡

初始化wpa_supplicant環境

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

參數：

-B - Fork into background.
-c filename - Path to configuration file.
-i interface - Interface to listen on.
-D driver - Optionally specify the driver to be used. For a list of supported drivers see the output of wpa_supplicant -h.
    nl80211 is the current standard, but not all wireless chip's modules support it.
    wext is currently deprecated, but still widely supported.

設置、獲取IP

自動獲取

dhcpcd wlan0

手動設置

ifconfig wlan0 192.168.1.11 broadcast 192.168.1.255 netmask 255.255.255.0

告知Gentoo RC系統網卡名字

cd /etc/init.d
ln -s net.lo net.wlan0
#start and stop it using the following commands:
/etc/init.d/net.eth0 start
/etc/init.d/net.eth0 stop
#開機啓動
rc-update add wlan0 default
