Nmap使用及常用命令解析-ChaBug安全

Nmap (“Network Mapper(网络映射器)”) 是一款开放源代码的 网络探测和安全审核的工具。它的设计目标是快速地扫描大型网络,当然用它扫描单个 主机也没有问题。Nmap以新颖的方式使用原始IP报文来发现网络上有哪些主机,那些 主机提供什么服务(应用程序名和版本),那些服务运行在什么操作系统(包括版本信息), 它们使用什么类型的报文过滤器/防火墙,以及一堆其它功能。虽然Nmap通常用于安全审核, 许多系统管理员和网络管理员也用它来做一些日常的工作,比如查看整个网络的信息, 管理服务升级计划,以及监视主机和服务的运行。

1. 参数

option note
-sS TCP SYN 扫描 (又称半开放,或隐身扫描)
-P0 允许你关闭 ICMP pings.
-sV 打开系统版本检测
-O 尝试识别远程操作系统
-A 同时打开操作系统指纹和版本检测
-v 详细输出扫描情况.

2. 常用命令

探测 cmd
获取远程主机的系统类型及开放端口 nmap -sS -P0 -sV -O <target>
获取远程主机的系统类型及开放端口 nmap -sS -P0 -A -v <target>
检查特定端口是否开放 nmap -p <port> <target> nmap -p <port1>,<port2> <target>

4. Chapter 3 ~::~ Gathering Additional Host Information

4.0.1. Getting information from WHOIS records

4.0.2. Collecting valid e-mail accounts

The script http-google-email is not included in Nmap's official repository. So you need to download it from http://seclists.org/nmap-dev/2011/q3/att-401/ http-google-email.nse and copy it to your local scripts directory. After copying http-google-email.nse , you should update the script database with:
