小编给大家分享一下OpenWRT如何启用工作模式开关和联网,希望大家阅读完这篇文章之后都有所收获,下面让我们一起去探讨吧!
主要配置 rc.local 脚本,内容如下:
read_gpio() {
(echo $1 > /sys/class/gpio/export) >& /dev/null
(echo "in" > /sys/class/gpio/gpio$1/direction) >& /dev/null
return `cat /sys/class/gpio/gpio$1/value`;
}
read_gpio 19;
v=$?;
read_gpio 20;
v=$v$?;
read_gpio 21;
v=$v$?;
read_gpio 22;
v=$v$?;
read_gpio 23;
v=$v$?;
case "$v" in
10001) v="ap";;
11001) v="repeater";;
01001) v="hotspot";;
11000) v="4th";;
*) v="error";;
esac
cp /etc/config/$v/* /etc/config/
logger working mode: $v
exit 0
原理是开机自动复制配置文件覆盖到 /etc/config/ 下,配置文件不需要全部,只要 firewall、network 和 wireless 就行了。按工作模式命名,创建三个目录:
mkdir /etc/config/ap
mkdir /etc/config/repeater
mkdir /etc/config/hotspot
后面,我们会把配置文件写好了,放在这些目录里。下面以 ap 为例,此模式是网口做 WAN,无线做 LAN,WAN 以 ADSL 接入为例,其它情况自行变通:
uci set wireless.@wifi-device[0].disabled=0;
uci set wireless.@wifi-iface[0].ssid='umu618.com';
uci set wireless.@wifi-iface[0].encryption='psk2+ccmp';
uci set wireless.@wifi-iface[0].key='WiFi 密码';
uci commit wireless;
wifi
uci delete network.lan.ifname
uci delete network.lan.type
uci add network interface
uci rename network.@interface[-1]='wan'
uci set network.@interface[-1].ifname='eth2'
uci set network.@interface[-1]._orig_ifname='eth2'
uci set network.@interface[-1]._orig_bridge='false'
uci set network.@interface[-1].proto='pppoe'
uci set network.@interface[-1].username='宽带账号'
uci set network.@interface[-1].password='宽带密码'
uci commit network
cp /etc/config/firewall /etc/config/ap/
cp /etc/config/network /etc/config/ap/
cp /etc/config/wireless /etc/config/ap/
再来说一下 repeater,网口做 LAN,无线做一个 AP Client 和一个 AP。注意,以下命令以初始化的配置文件为基础,请事先备份、还原,不要在配置过前面的 ap 模式后直接继续配置,可能会有问题。
uci add network interface
uci rename network.@interface[-1]='wwan'
uci set network.@interface[-1].proto='dhcp'
uci commit network
uci set wireless.@wifi-device[0].disabled=0;
uci set wireless.@wifi-iface[0].ssid='umu618.com';
uci set wireless.@wifi-iface[0].encryption='psk2+ccmp';
uci set wireless.@wifi-iface[0].key='WiFi 密码';
uci add wireless wifi-iface
uci set wireless.@wifi-iface[-1].network='wwan'
uci set wireless.@wifi-iface[-1].ssid='现有 WiFi 名字'
uci set wireless.@wifi-iface[-1].device='radio0'
uci set wireless.@wifi-iface[-1].mode='sta'
uci set wireless.@wifi-iface[-1].bssid='现有无线路由器的 MAC 地址'
uci set wireless.@wifi-iface[-1].encryption='psk2+ccmp'
uci set wireless.@wifi-iface[-1].key='现有 WiFi 密码'
uci commit wireless;
wifi
uci get firewall.@zone[1].network
uci show firewall.@zone[1]
uci set firewall.@zone[1].network='wan wan6 wwan'
uci commit firewall
/etc/init.d/firewall restart
cp /etc/config/firewall /etc/config/repeater/
cp /etc/config/network /etc/config/repeater/
cp /etc/config/wireless /etc/config/repeater/
