Nmap都能提供保证安全所需的知识水平和先发制人的思想

Ax_概述

Nmap是Network Mapper的缩写,是一种网络发现和安全审计工具。它以简单易记的标志着称,提供强大的扫描选项。Nmap被网络管理员广泛用于扫描

Nmap是hacker最常用的工具之一。它的易用性和清洁安装以及强大的扫描选项使其更受欢迎。

Usage: nmap [Scan Type(s)] [Options] {target specification}
TARGET SPECIFICATION:
  Can pass hostnames, IP addresses, networks, etc.

nmap [ <扫描类型> ...] [ <选项> ] { <扫描目标说明> }
#扫描技术
---
-sS    TCP同步扫描(TCP SYN)
-ST    TCP连接扫描
-sn    不进行端口扫描,只检查主机正在运行。该选项与老版本的-sP相同

-sA    TCP ack端口扫描

---
#主机发现
-Pn    只进行扫描,不ping主机
-sn    只有主机发现
-n     不进行DNS解析,加快扫描速度
-PS    使用SYN包对目标主机进行扫描。默认是80端口,也可以指定端口,格式为-PS22或-PS22-25,80,113,1050,35000,记住PS和端口号之间不要有空格
-PR    在本地网络上发现arp
-PU    使用udp ping扫描端口
---
#端口范围
-p<端口>        指定要扫描的端口,可以是一个单独的端口,也可以用逗号分隔开多
-P- 扫描所有端口
-F  快速端口扫描
---
#服务版本和操作系统检测
-O     激活对TCP/IP指纹特征(fingerprinting)的扫描,获得远程主机的标志,也就是操作系统类型
-A     主动扫描
-sV    探测服务版本信息
-V     显示扫描过程中的详细信息*
--
#时间和性能
-T0 偏执的IDS逃避
-T1 鬼鬼祟祟的IDS逃避
-T2 礼貌的IDS逃避
-T3 正常的IDS逃避
-T4 积极的速度扫描
-T5 疯狂的速度扫描 这翻译有点问题。。不过可以看懂,就是越来越快
---
#NSE脚本
-sC 默认脚本扫描
-script横幅   横幅抓住
---
#IDS逃避
-F  使用分段的IP数据包
-D  诱饵扫描
-G  使用给定的源端口号
---
#其它
-S<IP>          设置扫描的源IP地址
-g port         设置扫描的源端口
-oN             把扫描的结果重定向到文件中
-iL filename    从文件中读取扫描的目标一个端口,或者使用“-”表示端口范围

-exclude        排除指定主机
-excludefile    排除指定文件中的主机
nmap -A -v target_ip
nmap -sn -v target_ip
nmap -F -v target_ip
nmap -sV -v target_ip 
nmap -O -v target_ip

扫描局域网内所有的IP

nmap 0.0.0.0/24

范围扫描

nmap -sn 10.0.0.1-10 #<=可以使用这种地进范围进行扫描。


nmap -v -p 1-65535 <ip address>

这貌似是图形化的Nmap,叫Zenmap
nmap -T4 -A -v 192.168.0.168
