python使用nmap管理网络的编程初探

为了简单期间，我选择编制网段端口扫描的程序如下：

1.环境准备

   1.1 在pypi下载python－nmap最新版本python-nmap-0.3.4.tar.gz

   1.2 从nmap.org下载nmap软件，最新版本nmap－6.47.dmg

   1.3 安装上述两个软件

2. 创建network_port_scan.py如下：

#coding = utf-8

#!/usr/bin/env python

import nmap                         # import nmap.py module

nm = nmap.PortScanner()         # instantiate nmap.PortScanner object

nm.scan('10.0.0.4-254', '2195,2196,8080,9006,389,636')      # scan host 10.0.0.4 -10.0.0.254 ports ranged in '2195,2196,8080,9006,389,636'

nm.command_line()                   # get command line used for the scan : nmap -oX - -p <ports> <IP segment>

nm.scaninfo()                       # get nmap scan informations {'tcp': {'services': 'ports', 'method': 'connect'}}

nm.all_hosts()                      # get all hosts that were scanned

# print result as CSV

print(nm.csv())

最简单的端口扫描结果显示如下：

10.0.0.127;tcp;2195;;filtered;;;no-response;;;
10.0.0.127;tcp;2196;unknown;filtered;;;no-response;;3;

需要注意的是nmap软件必须安装，否则系统会报错。
