利用luci写了个wifidog认证服务，实现直接openwrt路由器本地认证。直接安装ipk安装包，然后修改/etc/wifidog.conf文件(需要先安装wifidog)，如下：

AuthServer {Hostname 192.168.1.1Path /cgi-bin/luci/wdas/MsgScriptPathFragment gw_message/?
}

主要的源码如下：

源码编译说明：

modules目录下的wifidogauth目录放到./feeds/luci/modules/下。

po/zh_CN/wifidogauth.po文件放到./feeds/luci/po/zh_CN/下。

./feeds/luci/contrib/package/luci/Makefile增加如下语句：

$(eval $(call module,wifidogauth,wifidog auth server,+luci-base))

然后 make menuconfig在luci-->Modules下找到luci-mod-wifidogauth选上。

make package/feeds/luci/luci/compile V=s

认证的用户名、密码的配置文件路径/etc/config/wifidogauth
