Linux 下使用C++进行Socket编程-use Linux for C Socket Programming

java based ftp server

一个非常强大的库，可以进行IP包的创建、发送和嗅探，并且可以进行端口扫描-a very powerful library, IP packets can create, send and sniffer, and can port scanning

基于xinu的tcp/ip协议栈，在xinu下可以编译运行。-Based on xinu of tcp/ip protocol stack, in xinu may be compiled to run.

完整的aodv实现，里面还有自己的编程思路及个人见解-complete aodv achieved, which also has its own programming ideas and personal insights

本程序是用winsock API函数编写网络部分，使用MFC编写应用程序框架 在测试时，发现在有的机器上只能做服务器，如果做客户端则无法连接上服务器， 而有的则相反 但在同一台机器上回环测试均成功! 不知道为什么??是不是因为防火墙或是windows的版本问题?不得而之! 使用UDP协议时，有时会出现客户端绑定失败问题!不知为何?-this procedure is used to prepare protocols of API function network, the use of MFC application framework prepared in the test, found in some machines can only do servers, so if the client is unable to connect to server, while others but on the contrary in the same machine loop testing success! Do not know why is it because of firewalls or windows version and not the problem! using UDP, sometimes there will be bundled with the client failure! I do not know why

linux epoll源码，支持大型服务器，适合高手研究-linux source epoll support large server, suitable for expert study

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.

Linux环境下Socket编程： 1.网络时间服务器timeserver，为网络上的用户提供时间服务，即为网络用户返回服务器的当前时间；记录发出请求的网络用户的IP地址（保存到文件中），格式如下： IP地址 请求时间 时间服务客户端timeclient，该客户端能够向服务器发送时间服务请求，并把获得的时间返回给用户。 采用TCP协议编写一个远程数据备份服务器，运行客户端将本地文件备份到远程的服务器中。 -Socket Programming Linux environment: 1. Network Time server timeserver, users on the network time service, namely, Internet users to return the server" s current time record request the user" s IP network address (saved to a file), format are as follows: IP address of a request for the time spent by service clients timeclient, the client can send to the server time to service requests, and to get the time to return to the user. TCP protocol used to prepare a remote data backup server, run the client local file backup to a remote server.

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
