[轉載]OpenWRT使用wifidog實現強制認證的WIFI熱點 | 半個橙子

首先安裝wifidogOpenWRT的路由器:php

  opkg updateweb

  opkg install wifidogsql

  

wifidog依賴下面這些模塊:數據庫

iptables-mod-extraapache

iptables-mod-ipoptapp

kmod-ipt-natless

iptables-mod-nat-extratcp

libpthreadoop

  

因爲trunk的固件更新會比較頻繁,會致使直接opkg install wifidog安裝不了,若是你湊巧又沒有備份與固件對應的Packages的話,就須要到http://downloads.openwrt.org/snapshots/trunk升級固件,而後再安裝wifidog我備份了一個20137月份(kernel =3.10.3-1-9da5017d589c0594e545ab00a51eecea)的版本的Packages,須要的話拿去用:this

http://openwrt.sinapp.net

  

若是你的路由器不是openwrt官方支持的版本的話,那就須要本身編譯固件。make menuconfig後,在Network–>Captive Portals中選擇wifidog.

wifidog1

安裝完成後,

/etc/init.d/wifidog enable

/etc/init.d/wifidog start

  

這時會拋出一個錯誤,由於咱們尚未設置AuthServer的信息。關於安裝wifidog更多的信息能夠參考:http://wiki.openwrt.org/doc/howto/wireless.hotspot.wifidog

  

下面安裝Auth Server,按照官方的說法:

AuthPuppy is the next generation authentication server for Wifidog networks.

源文檔 <http://www.authpuppy.org/>

不過貌似這wifidogAuthpuppy都已經N久沒更新了。。。 

 

AuthPutty是須要安裝apache2, php5MySQL。詳細介紹在這裏:http://www.authpuppy.org/doc/Getting_Started (Windows版點這裏)

 

安裝成功後,訪問AuthPuppy會要求設置一些數據庫信息,所有設置完成後能看到首頁:

wifidog2

 

固然了,咱們還須要設置管理員的帳號。

 

進入Manage pluginsInstall apAuthLocalUserPlugin,記得要enable這個插件。

wifidog3

 

而後,點擊Manage Nodes,把默認節點的status改爲deployed。這個GW(Gateway) ID default後面配置wifidog.conf的時候須要使用。

wifidog4

 

到這裏,AuthPuppy就基本配置完畢了。

 

下面回到路由器,編輯wifidog.conf,通常狀況下,咱們以後配置ExternalInterfaceGatewayInterfaceAuthServer這三項就能夠,其餘默認。下面是個人配置:

GatewayIDdefault           #注意這個ID必須跟AuthPuppyGW ID一致

# Parameter: ExternalInterface

# Default: NONE

# Optional

#

# Set this to the external interface (the one going out to the Inernet or your larger LAN).

# Typically vlan1 for OpenWrt, and eth0 or ppp0 otherwise,

# Normally autodetected

ExternalInterface eth0      #路由器外網的物理接口

 

# Parameter: GatewayInterface

# Default: NONE

# Mandatory

#

# Set this to the internal interface (typically your wifi interface).

# Typically br-lan for OpenWrt, and eth1, wlan0, ath0, etc. otherwise

GatewayInterface wlan0      #路由器內網的物理接口

AuthServer {

    Hostname 192.170.1.104

    SSLAvailable no

    Path /

 

CheckInterval 60

ClientTimeout 5

FirewallRuleSet global {

}

FirewallRuleSet validating-users {

    FirewallRule allow to 0.0.0.0/0

}

FirewallRuleSet known-users {

    FirewallRule allow to 0.0.0.0/0

}

FirewallRuleSet unknown-users {

    FirewallRule allow udp port 53

    FirewallRule allow tcp port 53

    FirewallRule allow udp port 67

    FirewallRule allow tcp port 67

}

FirewallRuleSet locked-users {

    FirewallRule block to 0.0.0.0/0

}

 

注意這個Interface是物理接口,而不是下面OpenWRT web界面中看到的interface。注意不是下面這個:

wifidog5

 

能夠看到個人Interface裏面沒有wlan0之類的選項,/etc/config/network裏面也看不到。

root@OpenWrt:~# cat /etc/config/network

config interface ‘loopback’

        option ifname ‘lo’

        option proto ‘static’

        option ipaddr ‘127.0.0.1’

        option netmask ‘255.0.0.0’

config globals ‘globals’

        option ula_prefix ‘fd09:fd03:490d::/48′

config interface ‘lan’

        option proto ‘static’

        option ipaddr ‘192.168.1.1’

        option netmask ‘255.255.255.0’

        option ip6assign ’60’

        option _orig_ifname ‘eth0′

        option _orig_bridge ‘false’

config interface ‘WAN’

        option proto ‘dhcp’

        option _orig_ifname ‘gretap0′

        option _orig_bridge ‘false’

        option ifname ‘eth0′

 

以前我用gretap0eth0設置ExternalInterfaceGatewayInterface,不行。反着來也不行。網上搜了一圈,找到下面的方法來獲physical interface

root@OpenWrt:~# ls -l /sys/class/net

lrwxrwxrwx    1 root     root             0 Jan  1  1970 eth0 -> ../../devices/platform/ag71xx.0/net/eth0

lrwxrwxrwx    1 root     root             0 Jan  1  1970 lo -> ../../devices/virtual/net/lo

lrwxrwxrwx    1 root     root             0 Aug  2 15:58 wlan0 -> ../../devices/platform/ar933x_wmac/net/wlan0

 

源文檔 <http://unix.stackexchange.com/questions/57309/how-can-i-tell-whether-a-network-interface-is-physical-device-or-virtual-alia>

 

 OK,原來我這邊也是有wlan0這個interface的,找到以後添加在wifidog.conf上。重啓wifidog,成功。

 

 另外:

You can also run wifidog in foreground/Debug mode:

wifidog -f -d 7

  -f means to run in foreground (do not become a background daemon)

  -d 7 increases Debug output level to the maximum
