linux一般不会自动安装nmap命令需要使用yum -y install nmap安装nmap命令，前提是您已经配置好了yum源。
nmap特点：
主机探测
端口扫描
版本检测
系统检测
支持探测脚本的编写
- nmap命令详解
nmap ip_address #nmap默认发送一个arp的ping数据包，来探测目标主机1-10000范围内所有开放的端口 [[email protected] scanport]# nmap 10.132.71.1 Starting Nmap 6.40 ( http://nmap.org ) at 2017-11-17 10:20 CST Nmap scan report for 10.132.71.1 Host is up (0.00030s latency).

-p自定义扫描的端口
例如：扫描1-200号端口
[[email protected] scanport]# nmap -p1-200 10.128.71.1 Starting Nmap 6.40 ( http://nmap.org ) at 2017-11-17 10:26 CST Nmap scan report for 10.128.71.1 Host is up (0.00030s latency).

例如:指定特定端口
[[email protected] scanport]# nmap -p135,136,137,139 10.128.71.1 Starting Nmap 6.40 ( http://nmap.org ) at 2017-11-17 10:28 CST Nmap scan report for 10.128.71.1 Host is up (0.0045s latency).

-sP指定扫描方式为ping（不扫描端口）
nmap -sP ip_address #使用ping方式扫描（不扫描端口）
nmap --traceroute ip_address #路由跟踪
nmap -sP xx.xx.xx.xx/24 #扫描一个网段（使用ping）
nmap -sP 10.1.1.1-255 #也可以扫描一个网段（使用ping）
nmap -sT ip_address #TCP contect()端口扫描
nmap -sU ip_address #UDP端口扫描
nmap -sS ip_address #TCP同步（SYN）端口扫描
nmap 10.1.1.1/24 #扫描一个网段使用默认端口扫描，结果同下面脚本
#!/bin/bash
for i in {1..254}
do
nmap 10.128.71.$i >>scan.port
done
nmap探测操作系统类型
nmap -O ip_address #扫描操作系统类型
nmap -A ip_address #使用默认扫描，ping扫描，操作系统扫描，脚本扫描，路由跟踪，服务探测等
[[email protected] scanport]# nmap -A 10.128.71.1 Starting Nmap 6.40 ( http://nmap.org ) at 2017-11-17 10:46 CST Nmap scan report for 10.128.71.1 Host is up (0.00028s latency).
