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

Please report any incorrect results at http://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 26.07 seconds Raw packets sent: 1147 (54.550KB) | Rcvd: 1091 (47.158KB)
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 Starting Nmap 5.51 ( http://nmap.org ) at 2015-10-28 22:04 CST Nmap scan report for 192.168.2.7 Host is up (0.019s latency). Not shown: 194 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 1723/tcp open pptp 53/udp open|filtered domain 68/udp open|filtered dhcpc MAC Address: C8:3A:35:C7:72:F1 (Tenda Technology Co.) Nmap done: 1 IP address (1 host up) scanned in 107.10 seconds
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 Starting Nmap 5.51 ( http://nmap.org ) at 2015-10-28 22:13 CST Nmap scan report for 192.168.2.7 Host is up (0.073s latency). Not shown: 996 closed ports PORT STATE SERVICE VERSION 21/tcp open ftp vsftpd 2.3.5 22/tcp open ssh OpenSSH 6.0p1 Debian 4+deb7u2 (protocol 2.0) 53/tcp open domain dnsmasq 2.62 1723/tcp open pptp linux (Firmware: 1) MAC Address: C8:3A:35:C7:72:F1 (Tenda Technology Co.) Service Info: Host: local; OSs: Unix, Linux Service detection performed. Please report any incorrect results at http://nmap.org/submit/ . Nmap done: 1 IP address (1 host up) scanned in 13.26 seconds
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 Starting Nmap 5.51 ( http://nmap.org ) at 2015-10-28 22:18 CST Nmap scan report for 192.168.2.7 Host is up (0.0029s latency). Not shown: 996 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 1723/tcp open pptp MAC Address: C8:3A:35:C7:72:F1 (Tenda Technology Co.)

进行ping扫描,打印出对扫描做出响应的主机:
nmap -sP 192.168.1.0/24
仅列出指定网络上的每台主机,不发送任何报文到目标主机:
nmap -sL 192.168.1.0/24
