TCP和UDP socket编程，向固定服务器发送学号姓名信息，用udp从服务器获得一个随机字符串(TCP and UDP socket programming, Student ID Name information sent to the fixed server udp from server to obtain a random string)

黑客攻击与防范技术，我所保存的最全的网络安全资料。(Hacker attacks and prevention techniques, I have saved the most complete network security information.)

本代码是利用socket套接字实现点对点的简单聊天软件程序。语言是C++。内附源码，项目设计报告，和可执行文件。(This code is using socket to realize P2P-based simple chatting software. Program lauguage is C++. Besides source code, also Included program design report and executable files.)

采用syn的扫描方式对一个网段的ip进行扫描，图形界面(Syn scan mode using a segment of ip scanning, graphical interface)

实现客户端和服务器端的通信，但是功能很有限，只是单向的通信。(To achieve client and server-side communication, but function is very limited, only one-way communication.)

SOCKET通信，一个服务端，一个客户端的通信。(SOCKET communications, a server, a client communication.)

A practical example of moving a form without title bar is simple, effective and worthy of reference.

说明：  实时视频传输有很大的实用价值，对采集到的原始视频信息进行压缩编码，获取己编码视频流是实现实时视频传输和QoS研究的关键。(Real-time video transmission are of great practical value of collected information for the original video coding, video streaming access to their own code is to achieve real-time video transmission and the key QoS.)

端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)
