简单介绍python-nmap 模块的使用
python-nmap是python的一个模块库，使用这个模块可以让python很方便的操作nmap扫描器来工作，它可以帮助管理员完成自动扫描任务和生成报告的工具，它还支持nmap的脚步输出。最新的版本是python-nmap-0.2.4.tar.gz,下载地址是：http://xael.org/norman/python/python-nmap/python-nmap-0.2.4.tar.gz
不过这个版本是适合python3.*来使用的，如果你的python版本还是2.*的话，还是使用这个版本，python- nmap.0.1.4.tar.gz, 下载链接是http://xael.org/norman/python/python-nmap/python-nmap-0.1.4.tar.gz
安装还是很简单的，解压缩，运行setup.py install之后，就搞定了。
下面贴出自带的example.py的源码：
#!/usr/bin/env python
# -*- coding: latin-1 -*-
import sys
import nmap # import nmap.py module
try:
nm = nmap.PortScanner() # instantiate nmap.PortScanner object
except nmap.PortScannerError:
print(‘Nmap not found’, sys.exc_info())
sys.exit(0)
except:
print(“Unexpected error:”, sys.exc_info())
sys.exit(0)
nm.scan(‘127.0.0.1′, ’22-443′) # scan host 127.0.0.1, ports from 22 to 443
nm.command_line() # get command line used for the scan : nmap -oX – -p 22-443 127.0.0.1
nm.scaninfo() # get nmap scan informations {‘tcp': {‘services': ’22-443′, ‘method': ‘connect’}}
nm.all_hosts() # get all hosts that were scanned
nm[‘127.0.0.1′].hostname() # get hostname for host 127.0.0.1
nm[‘127.0.0.1′].state() # get state of host 127.0.0.1 (up|down|unknown|skipped)
nm[‘127.0.0.1′].all_protocols() # get all scanned protocols [‘tcp’, ‘udp’] in (ip|tcp|udp|sctp)
nm[‘127.0.0.1′][‘tcp’].keys() # get all ports for tcp protocol
nm[‘127.0.0.1′].all_tcp() # get all ports for tcp protocol (sorted version)
nm[‘127.0.0.1′].all_udp() # get all ports for udp protocol (sorted version)

nm[‘127.0.0.1′].has_tcp(22) # is there any information for port 22/tcp on host 127.0.0.1
nm[‘127.0.0.1′][‘tcp’] # get infos about port 22 in tcp on host 127.0.0.1
nm[‘127.0.0.1′].tcp(22) # get infos about port 22 in tcp on host 127.0.0.1
nm[‘127.0.0.1′][‘tcp’][‘state’] # get state of port 22/tcp on host 127.0.0.1 (open
# a more usefull example :
for host in nm.all_hosts():
print(‘—————————————————-‘)
print(‘Host : %s (%s)’ % (host, nm.hostname()))
print(‘State : %s’ % nm.state())
for proto in nm.all_protocols():
print(‘———-‘)
print(‘Protocol : %s’ % proto)
lport = nm.keys()
lport.sort()
for port in lport:
print(‘port : %
s\tstate : %s’ % (port, nm[‘state’]))
print(‘—————————————————-‘)
# If you want to do a pingsweep on network 192.168.1.0/24:
nm.scan(hosts=’192.168.1.0/24′, arguments=’-n -sP -PE -PA21,23,80,3389′)
hosts_list = [(x, nm[‘status’][‘state’]) for x in nm.all_hosts()]
for host, status in hosts_list:
print(‘{0}:{1}’.format(host, status))
print ‘—————————————————-‘
# Asynchronous usage of PortScannerAsync
nma = nmap.PortScannerAsync()
def callback_result(host, scan_result):
print ‘——————’
print host, scan_result
nma.scan(hosts=’192.168.1.0/30′, arguments=’-sP’, callback=callback_result)
while nma.still_scanning():
print(“Waiting …”)
nma.wait(2) # you can do whatever you want but I choose to wait after the end of the scan
下面看下运行的效果：

其他功能大家可以自己实践，安装这个模块，首先系统必须要安装好nmap这个软件是必须条件。。。
