Description: 用于扫描你的电脑上所有的TCP端口的状态。利用这个功能，你可以轻松、快速的查出你的电脑上所使用的TCP端口，进而判断你的电脑是否中了木马。扫描出来的端口状态有两种：拒绝连接、接受连接。对于处于拒绝连接状态的端口，很可能是你的电脑为了与外部主机连接而使用的，通常情况下不会对你的网络安全构成威胁。而处于接受连接状态的端口，可能会对你的网络安全构成威胁，甚至很有可能是木马程序在运行!假若你想通过本端口扫描来判断你的电脑是否中了木马，在扫描时请不要运行其它网络程序，如果扫描结果还是有处于接受连接状态的端口，那请小心警惕!最好找个电脑高手来帮忙! 注意：对于137,138,139这三个TCP端口，即使这里的扫描没有给出扫描结果，也并不代表这三个端口不接受连接，通常情况下，Windows系统会开放这三个端口。你可以用“聊天客户”来测试这三个端口是否开放，具体用法如下：翻到“聊天客户”页，选择“主机列表”里的“本地主机”，将端口改为137(或138或139)，单击“连接”，若出现提示“建立连接”，则端口137(或138或139)是开放的。-used to scan your computer on all the TCP port state. Using this feature, you can easily and quickly identify your computer by the use of TCP port, then your judgment on whether a computer Trojan horse. Scanning the state has two ports : connecting refused to accept connections. For refused to connect at the state port, it is very likely your computer to connect with the mainframe and external use, under normal circumstances you will not pose a threat to network security.!accept the connection status of ports, care alert! finding the best computer experts to help! Note : This three TCP 137, 138 and 139 ports, even if the scanning here is not the results of the scan, it does not mean that this does not accept three port connectivity

Description: 端口扫描
扫描器的一个主要功能就是发现一个主机或网络并检查有什么服务正运行在这台主机上，更进一步还能测试这些服务，发现系统漏洞。要实现这些功能，只需要采用罪简单TCP connect（）扫描。操作系统提供的connect（）系统调用，用来与每一个目标计算机端口进行连接。如果端口处于侦听状态，那么connect（）就能够成功；否则这个端口不能使用，即没有提供服务。这个技术的最大有点是：无需任何权限。系统中的任何用户都有权利使用这个调用。另一个好处是速度，如果对每个目标端口以线性的方式，使用单独的connect（）调用，那将会花费相当长的时间。我们可以同时打开多个socket，从而加速扫描。使用非阻塞I/O允许设置一个较低的时间用尽周期，同时观察多个socket。但这种方法的缺点是很容易被发觉，并且被过滤掉。目标计算机的logs文件会显示一连串的连接和连接是出错的服务消息，并且能很快的使它关闭-port scanner scans one of the main functions is found a host or network and check what services are running in this host, but also further test these services, discovered vulnerabilities. To achieve these functions, the offense only needed a simple TCP

Description: 分别采用了TCP connect扫描和TCP SYN两种扫描方式。而且对于TCP connect扫描方式又分别通过CSocket类和Socket2编写了程序代码。从实际的测试效果来看，CSocket类和Socket2两种实现方式由于只是采用的编程类库不一样，而编程原理一样，所以效果也基本一样。而TCP SYN扫描则由于采用了非常规的扫描方式，特别是近几年防火墙的快速发展，几乎所有的防火墙都对这种方式进行防范，因此，扫描效果要视具体情况而定。同时，TCP SYN扫描方式必须运行于管理员组成员的模式下。-
We were used to scan and TCP SYN TCP connect two scanning methods. And for TCP connect scanning and Socket2 they were written by the CSocket class code. From a practical point of view the test results, CSocket class and Socket2 two ways since only use programming libraries are not the same, but the same principle programming, so the effect is basically the same. The TCP SYN scan is a result of the scanning unconventional way, especially in recent years, rapid development of firewall, almost all of the firewalls to prevent this manner, therefore, scan results depending on the specific circumstances. At the same time, TCP SYN scanning mode must run under the Administrators group members.

Description: Setting this work: a master server, and implement the interface connection to it customers. Communication protocol - either streaming protocol based on TCP / IP (note - HTTP is not a streaming protocol).
The server and client can be implemented in any programming language. The server must submit an application (for example a console) that implements the following functionality:
1. When a client connects to send him to an arbitrary number and display that number on the console
2. Upon receipt of a response the client to display the client s response to the console.
3. When a client disconnects display a message about this to the console.
4. Periodically (every x seconds) to send an arbitrary number of active clients
The client must implement the following:
1. Upon receipt of the server to bring it to the console, wait for 5 seconds and answer the same number increased by 1. So a dialogue between the client and the server will look as follows:-Setting this work: a master server, and implement the interface connection to it customers.

Description: A<========>B<=========>C<=====>D<======>E
A与B进程之间通过TCP的socket传递 主要掌握socket的流程：
A服务器端：
socket -->bind---->listen---->accept send read
B客户端：
socket-->connect->read send
不懂的可以man一下 man socket
B与C使用共享内存来交互
步骤是：shmget->shmat->直接读写--->shmdt shmctl(删除)
可以man
C与D之间使用消息传递进行
msgget-->msgrcv->msgsnd (注意这里的返回值判断发送正确与否 不是发送的字节数)
D使用fork（） 创建了一个进程 E
D跟E之间使用无名管道进行交互
E程序中可以使用有名管道 进行通讯。(A<========>B<=========>C<=====>D<======>E
Between the A and the B processes, the process of master socket is passed through the socket of the TCP:
A server side:
Socket -->bind---->listen---->accept send read
B client:
Socket-->connect->read send
Do not understand the ability to man man socket
B and C interact with shared memory
The step is: shmget->shmat-> read and write --->shmdt shmctl directly (delete)
Can man
Message passing between C and D
Msgget-->msgrcv->msgsnd (note that the return value here determines whether to send correctly or not the number of bytes sent)
D uses fork () to create a process E
Interaction between D and E using anonymous pipes
E programs can communicate with famous pipes.)
