无线网络(wifi)配置

Gentoo中有多种方式配置网络(每种之间都是冲突的,所以只能选择一种)

• wpa_supplicant
• nmcli/nmtui
• NetworkManager

使用wpa_supplicant配置方法

只需要在rc-update里关闭NetworkManager(如果默认有启动的话)

/etc/init.d/NetworkManager stop

假设无线网卡名为wlan0

cd /etc/init.d
ln -s net.lo net.wlan0

添加如下代码到/etc/con.d/net 中才能自动获取IP地址

modules_wlan0="wpa_supplicant"
config_wlan0="dhcp"

添加如下配置到/etc/conf.d/wpa_supplicant 中

wpa_supplicant_args="-B -M -c/etc/wpa_supplicant/wpa_supplicant.conf"

设置权限(限制查看wifi密码)

chmod 600 /etc/wpa_supplicant/wpa_supplicant.conf

配置/etc/wpa_supplicant/wpa_supplicant.conf 文件

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=users
update_config=1
network={
	ssid="ap_ssid_name"
	bssid=94:d9:b3:a4:01:de
	psk="aka_wifi_passwd"
}

使用wpa_cli来连接

wpa_cli add_network
wpa_clit set_network 0 ssid "ap_ssid_name"
wpa_clit set_network 0 psk "aka_wifi_passwd"
wpa_cli enable_network 0
wpa_cli select_network 0
wpa_cli save_config

开机启动wpa_supplicant

rc-update add wpa_supplicant default

手动开启和关闭wpa_supplicant

/etc/init.d/wpa_supplicant <start | stop | restart>
或
rc-service wpa_supplicant <start | stop | restart>

使用NetworkManager方法

连接ssid+password的wifi热点

sudo /etc/init.d/NetworkManager start
sudo nmcli device wifi connect <SSID> password <PASSWD>

连接需要用户名和密码的ap(参考连接)

先设置对应的信息

export WIFI_USER_NAME="your-user-name"
export WIFI_PASSWORD="your-password"
export WIFI_CON_ID='your-connection-one'
export WIFI_SSID='your-ap-ssid'

建立连接(会在/etc/NetworkManager/system-connections目录下生成对应的配置文件)

nmcli connection add \
	type wifi \
	con-name $WIFI_CON_ID \
	ifname wlan0 \
	ssid $WIFI_SSID \
	-- \
	wifi-sec.key-mgmt wpa-eap \
	802-1x.eap peap \
	802-1x.phase2-auth mschapv2 \
	802-1x.identity $WIFI_USER_NAME \
	802-1x.password $WIFI_PASSWORD

启动/关闭连接

nmcli connection up id $WIFI_CON_ID
nmcli connection down id $WIFI_CON_ID

删除连接

nmcli connection delete id $WIFI_CON_ID
