网络经典命令行指令

运用安全套接字协议实现安全隧道。这是专为那些不具有外部IP地址却仍想实现互联网服务的人设计的。服务器被置于一台拥有公网地址的计算机上。客户端运行在防火墙/网关后的某台计算机上。这使得客户端可以访问互联网。运行服务器端进程无需超级用户特权。也无须使用任何其他进程或线程。-use Secure Socket security agreement tunnel. This is designed for those who do not have external IP addresses still wants to achieve Internet services in the design. Servers are placed with a public address on a computer. Client runs on firewall/gateway of a computer. This enables the client to access the Internet. Process server running without superuser privileges. No need to use any other processes or threads.

linux里面的网络工具代码,用于无线局域网-linux tools inside the network code for wireless LAN

一个有趣的网络连接程序,输入地址可直接连接到该网站上-an interesting network connections and input address can be connected directly to the site

This document is a tutorial on network simulator-2(ns-2), a simulation environment for computer networking field of engineering. It outlines step-by-step flow of learning.

工作中调试应用编写的小程序，下载文件到本地。-Application debugging work to prepare a small procedure, download the file to the local.

total是最后的版本。包括的全是最新的物理层和数据链路层。另外还有pro1和pro2的打包程序和调用它们形成的各自的界面程序，以及最后调用各个界面形成的总界面程序。由于时间匆忙，对数据链路层协议的界面化工作只做到了pro2，总界面上已经留了所有6个程序的地方。PhysicalLayer包中包含了所有的物理层的程序的版本，以及它们各自的演示程序(一般为Physical)及打包程序(一般为PhyLayer)。显示了整个物理层编写及修改演化的过程，仅供参考。Datalink Layer包中包含了数据链路层程序的各个版本。包含数据链路层基本操作模块(Datalink.java)及各个协议的版本(pro1-pro3)。以及它们各自的演示程序及打包程序。显示了整个物理层编写及修改演化的过程，仅供参考。运行方法：只需要Java的运行环境。先要预装java，这里使用的是java的j2sdk-1_4_2_01-windows-i586版本。最新的1.5.0应该也支持。采用的编译器是Jcreator，其他的编译器也应该是可以用的。-total is the final version. Included are all the latest physical layer and data link layer. Another pro2 PRO1 and the packing procedures and the use of their respective formation of the interface procedures, as well as various interface called the final form of the total interface procedures. Because of the time available, the data link layer protocol interface work is just a pro2 total interface has left all six local procedures. PhysicalLayer package contains all of the physical layer version of the procedure, as well as their r

在ns发布的版本中，不包括IEEE802.11PCF功能的实现，这个源代码填补了这个空白。-In the ns release version, does not include the realization of IEEE802.11PCF function, the source code to fill the gaps.
