port scanning (including source code)

一个以dreamweaver2004为工具开发asp的教程，里面包括了源码~-dreamweaver2004 as a tool to develop the Guide asp, they include the source ~

在lcx源码的基础上改进的，http隧道通讯代码是在pcshare里面扣出来的，主要完成改的是-listen和-slave那块，-trans因为没有用到，所以就没有改。

多进程并发服务器。该程序等候客户连接，一旦连接则显示客户的地址，接着接收该客户的名字并显示。然后接收来自该客户的信息（字符串）。每当收到一个字符串，则显示该字符串，并将字符串反转，再将反转的字符发回客户。之后，继续等待接收该客户的信息直至该客户关闭连接。服务器具有同时处理多客户的能力。-more complicated process server. The procedure for connecting customers, once the connection is shown to the customer address, and then receive the customer"s name and display. Before receiving from the customer"s information (string). Whenever received a string, it shows that the string, the string will be inverted, and then reverse the characters back customers. Continue, after waiting for the customer to receive the information until the customer close the connection. Servers simultaneously with the ability to more customers.

Client程序同样分别创建一个TCP socket 和一个UDP socket，首先client使用TCP socket连接TCP Server。 连接成功后显示提示信息； 然后client端向TCP Server发送“GET UDP PORT”字符串，Server收到后向client回送自己的UDP Server 端口号（即Client端仅知道TCP Server的端口号而不知道UDP Server的端口号）； client在收到UDP Server的端口号后, 为用户显示3个选项： 1．“Get current time（TCP）”服务器时间 2．“Echo Mode（UDP）”回显6 3．“Exit the program”. -Client program also creates a TCP socket, respectively, and a UDP socket, the first client to use TCP socket connection TCP Server. After a successful connection displays a prompt message and then client-side to the TCP Server sends " GET UDP PORT" string, Server receipt back to the client to send their UDP Server port number (ie, Client-side only to know the TCP Server" s UDP port number do not know Server" s port number) client received UDP Server port number, in order to the user three options: 1. " Get current time (TCP)" server time 2. " Echo Mode (UDP)" echo 63. " Exit the program" .
