基于Netfilter的网络用户认证系统

Authentication system of network user based on Netfilter

随着宽带的发展,对网络用户的身份认证和合理控制十分重要.为保证各用户合理地使用校园网,在Linux操作系统上设计了一个基于Netfilter框架的校园网出口认证系统.该系统在Netfilter框架的支持下,能对上网用户进行IP连接数和带宽控制.另外,系统提供Web界面认证,且用户可以选择不同的网络出口和使用的时长.

With the development of bandwidth,it is important to identify the users and control their use.This paper designs an authentication system based on Netfilter in Linux operation system.It can control the number of connections and bandwidth of IP with the support of Netfilter's frame.It can provide authentication based on Web and the users can choose different exits of network and the range of time which they will retain.
