Nmap是一款非常强大的主机发现和端口扫描工具,而且nmap运用自带的脚本,还能完成漏洞检测,同时支持多平台。 官网 一般情况下,Nmap用于列举网络主机清单、管理服务升级调度、监控主机或服务运行状况。 Nmap可以检测目标机是否在线、端口开放情况、侦测运行的服务类型及版本信息、侦测操作系统与设备类型等信息。 Nmap的优点: 灵...

在这种情况使用这个选项给出你的IP地址。-g port 设置扫描的源端口。一些天真的防火墙和包过滤器的规则集允许源端口为DNS(53)或者FTP-DATA(20)的包通过和实现连接。显然,如果攻击者把源端口修改为20或者53,就可以摧毁防火墙的防护。-oN 把扫描结果重定向到一个可读的文件 logfilename 中。-oS 扫描结果...
