端口扫描程序设计详细的报告+源代码

1、网络综合实验任务书目的与要求1. 性质：设计性实验。2. 任务：设计并实现一个端口扫描程序，检测某个 IP或某段IP的计算机的端口工作 情况。3. 目的：加深对课堂讲授知识的理解， 熟练掌握基本的网络编程技术和方法，建立网络编程整体概念，使得学生初步具有研究、设计、编制和调试网络程序的能力。4. 要求：熟悉有关定义、概念和实现算法， 设计出程序流程框图和数据结构，编写出完整的源程序，基本功能完善，方便易用，操作无误。5. 学生要求人数：1人。二、主要内容1. 编写一个端口扫描程序，能够显示某个IP或某段IP的计算机的某一个或某些端口是否正在工作。基本工作过程如下：(1)设定好一定的端口扫描范围

2、；(2)设定每个端口扫描的次数，因为有可能有的端口一次扫描可能不通；(3)创建socket,通过socket的connect方法来连接远程IP地址以及对应的端口；(4)如果返回false,表示端口没有开放，否则端口开放。三、进度计划序号设计内容完成时间备注1任务布置及资料收集第1周、周二2软件方案设计与制定第1周周三至周四3编程实现第1周周周五至第2周周二4程序测试与修改，撰写报告第2周周三至周五上午5报告提交，软件验收周五卜午四、设计成果要求2. 完成规定的实验任务，保质保量;3. 完成综合实验报告， 要求格式规范，内容具体而翔实，应体现自身所做的工作，注 重对实验思路的归纳和对问题解决过程

3、的总结。五、考核方式1. 平时成绩+验收答辩+实验报告；2. 五级分制。学生姓名：指导教师：2009年6月8日器品用。"、综合实验的目的与要求1 .目的：加深对课堂讲授知识的理解，熟练掌握基本的网络编程技术和方法，建立网络编程整体概念，加深对 JAVA编程语言的使用，促进编程能力的提高，同时为网络编程打下一个比较好的基础。同时对实验的过程要有完全的了解。2 .要求：熟悉有关定义、概念和实现算法，设计出程序流程框图和数据结构，编写出 完整的源程序，基本功能完善，方便易用，操作无误。、综合实验正文1. 编程语言的选择针对编写的是端口扫描的程序，所以我选择了JAVA编程，因为要简单而方便的

4、试验端口扫描的功能。2. 端口扫描实现的功能是：显示某个IP或某段IP的计算机的某一个或某些端口是否正在工作3. 1如何选择IP段和端口创建socket,通过socket的connect方法来连接远程IP地址以及对应的端口。而我使用 的是socket函数来实现端口的扫描和IP地址的选择扫描。4. 2如何实现快速扫描端口通过实现多线程，当一个 IP或者一个端口同时分配多个线程进行扫描，速度会比单线 程扫描快许多。5. 3显示扫描结果可以在使用JAVA编写的时候，可以通过使用 JScrollPane控件实现显示结果。6. 4实现要求功能之余美化外观3.创建应用程序界面3. 1建立主窗体，“JAVA
