使用Java开发多线程端口扫描工具(二)

一 介绍

       这一篇文章是紧接着上一篇文章(http://www.zifangsky.cn/2015/12/使用java开发多线程端口扫描工具/)写的,端口扫描的原理不用多少,我在上一篇文章中已经说过了,至于目的大家都懂得。在这一篇文章里,我主要是对端口扫描工具的继续完善,以及写出一个比较直观的图形界面出来,以方便我们测试使用。界面如下:

wKiom1aQ2C2RsVlsAADA5eOctiQ635.png

       这个工具主要是实现了以下几点功能:(1)两种扫描方式,一种是只扫描常见端口,另一种是设置一个起始和结束端口,依次探测。当然,原理很简单,用for循环就可以了;(2)输入一个域名或者IP后,可以自定义扫描线程,这一点是非常有用的,因为有的服务器是装了360,云锁或者安全狗的,扫描线程过大或许会被封IP。

注:文末我会给出简易的可执行jar文件的下载链接
