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 书一、 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周周一、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，软件验收周五下午四、设计成果要求1 完成规定的实验任务，保质保量；2 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的

4、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21 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。22 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。23 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。24 实现要求功能之余美化外观3创建应用程序界面31 建立主窗体 ，“JAVA端口扫描器”图1-132 IP地址的输入部分图
