Python之nmap库的使用_C站训练营学-Linux

Nmap是一款网络扫描和主机检测的非常有用的工具。Nmap是不局限于仅仅收集信息和枚举，同时可以用来作为一个漏洞探测器或安全扫描器。它可以适用于winodws,linux,mac等操作系统。
python-nmap是一个帮助使用nmap端口扫描器的python库。它允许轻松操纵nmap扫描结果，并且将是一个完美的选择，为需要自动完成扫描任务的系统管理员提供的工具并报告。它也支持nmap脚本输出。

1. python nmap 安装

需要安装nmap软件和python_nmap第三方库。nmap的下载地址如下是https://nmap.org/download.html。

2. python nmap 的使用

2.1. 查看nmap版本

>>> import nmap
>>> n = nmap.PortScanner()
>>> n.nmap_version()
(7, 70)

2.2. 查看nmap命令

1
2
3

>>> date = n.scan("117.185.17.151","1-1024","-sV")
>>> n.command_line()
'nmap -oX - -p 1-1024 -sV 117.185.17.151'

2.3. scan 用法

def scan(self,
         hosts: str = '127.0.0.1',   #主机
         ports: Any = None,          #端口
         arguments: str = '-sV',     #扫描参数
         sudo: bool = False)         #是否用管理员身份扫描

2.4. 查看nmap扫描信息

>>> n.scanstats()
{'timestr': 'Wed Jan 02 12:46:46 2019',   #开始时间
'elapsed': '24.80',                       #扫描时间
'uphosts': '1',                           #存活主机
'downhosts': '0', 
'totalhosts': '1'}

2.5. 查看nmap扫描结果

>>> n.csv()
'host;hostname;hostname_type;protocol;port;name;state;product;extrainfo;reason;version;conf;cpe\r\n
117.185.17.151;;;tcp;80;http;open;Apache httpd;;syn-ack;;10;cpe:/a:apache:http_server\r\n
117.185.17.151;;;tcp;443;http;open;Apache httpd;;syn-ack;;10;cpe:/a:apache:http_server\r\n'

列名	端口1	端口2	解释
host	117.185.17.151	117.185.17.151	IP
hostname	-	-	主机名称
hostname_type	-	-	IP类型
protocol	tcp	tcp	协议
port	80	443	端口
name	http	http	服务名称
state	open	open	端口状态
product	Apache httpd	Apache httpd	服务器类型
extrainfo	-	-	其他信息
reason	syn-ack	syn-ack	端口回复
version	-	-	版本
conf	10	10	配置
cpe	cpe:/a:apache:http_server	cpe:/a:apache:http_server	消息头

2.6. 查看nmap扫描IP

1 2	>>> n.all_hosts() ['117.185.17.151']

2.7. 查看对应IP相关信息

#主机状态
>>> >>> n["117.185.17.151"].state()
'up'

#用什么协议发现的端口
>>> n["117.185.17.151"].all_protocols()
['tcp']

#tcp协议开放的端口
>>> n["117.185.17.151"]["tcp"].keys()
dict_keys([80, 443])

#查看指定协议端口是否开放
>>> n["117.185.17.151"].has_tcp(80)
True
>>> n["117.185.17.151"].has_tcp(81)
False

#查看指定端口协议的信息
>>> n["117.185.17.151"]["tcp"][80]
{'state': 'open', 'reason': 'syn-ack', 'name': 'http', 'product': 'Apache httpd', 'version': '', 'extrainfo': '', 'conf': '10', 'cpe': 'cpe:/a:apache:http_server'}
>>> n["117.185.17.151"].tcp(80)
{'state': 'open', 'reason': 'syn-ack', 'name': 'http', 'product': 'Apache httpd', 'version': '', 'extrainfo': '', 'conf': '10', 'cpe': 'cpe:/a:apache:http_server'}
>>> n["117.185.17.151"]["tcp"][80]["name"]
'http'

3. python namp 主机存活检测

import nmap
n = nmap.PortScanner()
n.scan(hosts="192.168.1.1/29", arguments="-sP")
for x in n.all_hosts():
    print(x+":"+n[x]["status"]["state"])

#执行结果：
192.168.1.1:up
192.168.1.2:up
192.168.1.4:up
192.168.1.5:up

4. python nmap 端口检测

import nmap
n = nmap.PortScanner()
n.scan(hosts="192.168.1.1/30", arguments="-sV -p 1-1024")
for x in n.all_hosts():
    print("Host: " + x)
    print("State: " + n[x].state())
    print("************************")
    for y in n[x].all_protocols():
        print("Protocols: " + y)
        print("↓↓↓↓↓↓↓↓↓")
        for z in n[x][y].keys():
            print("port: " + str(z) + " | name: " + n[x][y][z]["name"] + " | state: " + n[x][y][z]["state"])
    print("---------------------------")



##执行结果

Host: 192.168.1.1
State: up
************************
Protocols: tcp
↓↓↓↓↓↓↓↓↓
port: 22 | name: ssh | state: filtered
port: 80 | name: http | state: open
port: 443 | name: http | state: open
---------------------------
Host: 192.168.1.2
State: up
************************
Protocols: tcp
↓↓↓↓↓↓↓↓↓
port: 22 | name: ssh | state: filtered
port: 53 | name: domain | state: open
port: 514 | name: shell | state: filtered
port: 873 | name: rsync | state: filtered
---------------------------

5.PortScannerYield的使用

import nmap

n = nmap.PortScannerYield()
for x in n.scan(hosts="192.168.0.1/24", arguments="-sP"):
    print(x[0])
