Python-nmap Port Scan Example

Python-nmap is an encapsulation of NMAP commands, allowing Python to operate the Nmap scanner

First install Nmap

Yum Install Nmap-y

# #shell命令操作端口扫描方法见此文: http://blog.51cto.com/superleedo/2094273

Then install the Python-nmap module

Open https://pypi.org/project/python-nmap/#files

wget https://files.pythonhosted.org/packages/dc/f2/9e1a2953d4d824e183ac033e3d223055e40e695fa6db2cb3e94a864eaa84 /python-nmap-0.6.1.tar.gz

CD python-nmap-0.6.1

Python setup.py Install

Perform a scan

Python scan.py Please input hosts and port:192.168.1.124 80,443,22,3306,8080----------------------------------------- -----------host:192.168.1.124 (test01.test.com.cn) state:up----------protocol:tcpport:22 State:openport:8 0 state:openport:443 state:closedport:3306 state:openport:8080 state:open

Please input hosts and port:

The above host input supports a variety of forms such as: www.baidu.com, 192.168.1.*, 192.168.1.1-20, 192.168.1.0/24 after the port can be 21,22,80,3306 can also be used 21-3306
