WiFiDog certification Advantages and disadvantages WiFiDog principle

The portal certification method has multiple, we have chosen a very common open source project WiFiDog, support OpenWrt, large user groups, information is more perfect, Chinese information more.
Key Benefits:

1. Open Source (Https://github.com/wifidog GitHub, provides source code and PHP-based authentication Gateway source code)
2. Domestic use of wifidog is relatively common, two of times to develop more easily.
3. Code portability is high and virtually unlimited on all platforms

(Summary: Low cost, easy to get started.) ）

At present, there are some shortcomings

1. Through the actual capture packet discovery, heartbeat packet constantly check the user online situation, gateway server performance overhead.
2. Based on Iptables, the protocol is cumbersome and performance is relatively poor.
3. Privacy issues, no encrypted URLs are delivered directly with privacy information.

Here's a look at the WiFiDog working mechanism:
Working mechanism
/ping Heartbeat Interface

"Get/ping/?gw_id= Gateway id&sys_uptime=1183&sys_memfree=105884&sys_load=0.14&wifidog_uptime=1169 HTTP /1.0 "

/login New user authentication jump page

Get/login/?gw_address=111&gw_port=111&gw_id=111&mac=88:72:0d:f2:88:29&url=url HTTP/1.1

/auth User Detection

/auth/?stage=counters&ip=192.168.10.81&mac=88:72:0d:f2:a8:29&token=85ea71f2484b2c52fee& incoming=5638570&outgoing=722214&gw_id=111 http/1.0
