資源簡介
計算機信息網絡的發展加速了信息化時代的進程，但是隨著社會網絡化程度的增加，對計算機網絡的依賴也越來越大，網絡安全問題也日益明顯。端口掃描技術是發現安全問題的重要手段之一。一個端口就是一個潛在的通信通道，也就是一個入侵通道。對目標計算機進行端口掃描，能得到許多有用的信息。掃描器通過選用遠程TCP/IP不同的端口的服務，并記錄目標給予的回答，通過這種方法，可以搜集到很多關于目標主機的各種有用的信息，從而發現目標機的某些內在的弱點。
編寫一個簡單的主機端口掃描程序，要求能夠探測目的主機的端口狀態。
（1）要求用戶可以在參數中輸入需要掃描的目的主機的IP地址與端口，輸出端口的狀態信息。
（2）要求使用
