WifiDog 认证原理和流程

WifiDOG是一个热点系统,包含了认证服务器和客户端两部分组成,认证原理大体说下:

General Flow Description:

一般流程描述:

①The client does his initial request, as if he was already connected, (e.g.:http://www.6hl.cn)

客户端发出初始化请求,比如访问 www.6hl.cn 这个站点

②The Gateway's firewall rules mangle the request to redirect it to a local port on the Gateway. When that's the done, the Gateway provides an HTTP Redirect reply that contains the Gateway ID, Gateway FQDN and other informations

网关的防火墙规则将这个请求重定向到本地网关的端口上。当做完这个工作,网关提供一个HTTP重定向回复,包含了Gateway的ID,Gateway的FQDN以及其他的信息。

③The Client does his request to the Auth Server as specified by the Gateway, see Login Protocol

用户向认证服务器发出认证请求

http://auth_server/login?

gw_id=[GatewayID, default: "default"]

gw_address=[GatewayAddress, internal IP of router]

gw_port=[GatewayPort, port that wifidog Gateway is listening on]

url=[user requested url]

④The Gateway replies with a (potentially custom) splash (login) page

网关返回一个(可以是自定义的)splash(也称作“登录”)页面

⑤The Client provides his identification informations (username and password)

用户提供他的凭据信息,比如用户名和密码

⑥Upon succesful authentication, the client gets an HTTP Redirect to the Gateway's own web server with his authentication proof (a one-time token),http://GatewayIP:GatewayPort/wifidog/auth?token=[authtoken]

成功认证的话,客户端将会被重定向到网关的自己的web页面上,并且带有一个 认证凭据(一个一次性的token),内容比如

http://GatewayIP:GatewayPort/wifidog/auth?token=[authtoken]

⑦The Client then connects to the Gateway and thus gives it his token

用户就是用获取到的凭据访问网关

⑧The Gateway requests validation of the token from the Auth Server, see Client Protocol【见登录心跳】

网关去认证服务器询问token的有效性

⑨The Auth Server confirms the token

认证服务器确认token的有效性

①①The Gateway then sends a redirect to the Client to obtain the Success Page from the Auth Server, redirects tohttp://auth_server/portal/

网关发送重定向给客户端,以从认证服务器上获取 成功提示页面,重定向到http://auth_server/portal/这个位置

①②The Auth Server notifies the Client that his request was successful

认证服务器通知客户请求成功,可以上网了。
