1、安装

bzip2 -cd nmap-6.49BETA6.tar.bz2 | tar xvf -  
cd nmap-6.49BETA6  
./configure  
make  
su root  
make install

2、使用

nmap 目标主机

nmap 192.168.2.7  

Starting Nmap 6.49BETA6 ( https://nmap.org ) at 2015-10-28 23:30 CST  
Warning: File ./nmap-services exists, but Nmap is using /usr/local/bin/../share/nmap/nmap-services for security and consistency reasons.  set NMAPDIR=. to give priority to files in your local directory (may affect the other data files too).

目标主机192.168.2.7 处于 up 状态，开放了21，22，53，1723端口，最后给出了网卡信息

2)nmap -T4 -A -v 目标主机

-T4是指定扫描过程中使用的时序模板，总共有6个等级，等级越高，扫描速度越快，但也容易被防火墙或者入侵检测设备发现

3)nmap 常用参数

-sn : 只进行主机发现扫描，不进行端口扫描  
-Pn : 跳过主机发现扫描，将所有指定的主机都视为在线状态，进行端口扫描  
-sL : 仅仅列出指定的目标主机 IP，不进行主机发现扫描  
-PS/PA/PU/PU[portlist] : 指定使用 TCP SYN/TCP ACK/ UDP/SCTP方式进行主机发现，例如 nmap -PS80,2  
-PE/PP/PM : 指定 nmap 使用 ICMP echo、timestamp、network 请求报文方式发现主机  
-PO : 使用 IP 协议包探测目标主机是否在线  
-n/-R : 指定是否使用 dns 解析，其中，-n 表示不进行 dns 解析，-R 表示总进行 dns 解析

例如

nmap -sn -PE -PS22,80 -PU53 192.168.2.7  

Starting Nmap 5.51 ( http://nmap.org ) at 2015-10-28 22:00 CST  
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn  
Nmap done: 1 IP address (0 hosts up) scanned in 0.43 seconds

4)nmap 端口扫描

nmap 扫描端口状态分为6类

open : 表示端口是开放的  
closed : 表示端口是关闭的  
filtered : 表示端口被防火墙屏蔽，无法进一步确认状态  
unfiltered : 表示端口没有被屏蔽，但是否处于开放状态，还需要进一步确定  
open|filtered : 表示不确定状态，端口可能开放可能关闭  
closed|filtered : 表示不确定状态，端口可能关闭，可能屏蔽

端口扫描的用法

-sS/sT/sA/sW/sM : 指定使用 TCP SYN/Connect()/ACK/Window/Maimon scans 来对目标主机进行端口扫描  
-sU : 指定使用 UDP 扫描方式扫描目标主机的 UDP 端口状况  
-sN/sF/sX : 指定使用 TCP Null/FIN/Xmas sans 秘密扫描方式来协助侦测目标主机的 TCP 端口状态  
-p <port rangs> : 仅仅扫描指定的一个或一批端口。例如 -p80/-p1-100/-p T:80-88,8000,U:53,111,S:9,其中 T 表示 TCP 协议，U 表示 UDP 协议，S 表示 SCTP 协议  
-F : 快速扫描模式，仅仅扫描开放率高的100个端口  
--top-ports <number> : 仅扫描开放率高的 number 个端口

例子

nmap -sU -sS -F 192.168.2.7

5)nmap 程序版本侦测

nmap 选项或参数目标主机

-sV : 设置 nmap 进行版本侦测  
--version-intensity <level> 设置版本侦测的强度值，0-9，默认是7。这个数值越高，探测出的版本越精确，但扫描时间也更长  
--version-light : 设置使用轻量级的侦测方式，相当于侦测强度为2  
--version-trace : 显示版本侦测的详细过程

例子

nmap -sV 192.168.2.7

6)nmap 操作系统的侦测

nmap 选项或参数

-O : 设置 nmap 进行操作系统侦测  
--osscan-guess : 猜测目标主机的操作系统类型，nmmap 会给出可能性的比率，用户可以根据提供的比率综合判断操作系统类型

例子

nmap -O --osscan-guess 192.168.2.7
