udp端口扫描(python-nmap代码)

nmapScanUdp.py

#! /usr/bin/python

import nmap
# python-nmap url : http://xael.org/norman/python/python-nmap/python-nmap-0.1.4.tar.gz

nm = nmap.PortScanner()
nm.scan(hosts='192.168.1.0/24', arguments='-n -p 161 -sU ')
hosts_list = [(x, nm[x][u'udp'][161]['state']) for x in nm.all_hosts()]
#print nm.all_hosts()
#print nm[u'192.168.1.100'][u'udp'][161]['state']
for host, status in hosts_list:
	print('{0}:{1}'.format(host, status))

这个依赖nmap程序，底层是调用shell下的nmap实现的：

launch 'nmap -V', we wait after 'Nmap version 5.0 ( http://nmap.org )'

p = subprocess.Popen(['nmap', '-V'], bufsize=10000, stdout=subprocess.PIPE)
self._nmap_last_output = p.communicate()[0] # store stdout
