资源描述

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) 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 日一、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。二、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 2．1 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。 2．2 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。 2．3 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。 2．4 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端口扫描器” 图1-1 3．2 IP地址的输入部分图1-2 3．3 端口部分，其中包括指定的端口和指定扫描的端口范围图1-3 3．4 多线程的实现和延时的控制部分图1-4 3．5 增加的保存及快捷键功能图1-5 4．扫描的整个过程 4．1 填写IP地址 192.168.1.100—192.168.1.120 4．2 填写端口扫描的范围为1—300 4．3 线程数选择为100 4．4 扫描结果如下图1-6 三．端口扫描的主要部分程序如下 import .*;
