IP隧道技术及其在Linux中的实现

随着Internet应用的普及,如何在公网上进行安全的传输成为一个不容忽视的问题,利用隧道技术实现虚拟专网(VPN)是一个有效简便的措施.Linux的应用近年也以惊人的速度增长,在Linux下进行隧道传输,进而实现VPN成为很多人感兴趣的课题.本文就IP隧道技术本身及其在Linux中的实现进行了讨论,概要地给出了构建VPN的逻辑步骤及几种使用方法.

The IP Channel and Its Implementation Under Linux

With the rapid development of the Internet,security in transferring information is becoming more and more important. There are several ways to strengthen it and the IP Channel proves to be efficient and convenient. In recent years, the application of Linux has been growing rapidly. How to implement the IP Channel under Linux and thereafter the VPN (visual private netwock) has turned out to be an interesting subject. This paper discusses the IP channel technology, its implementation logical steps to design the VPN and several ways to use it.
