Python-Nmap使用及案例

　　实验案例
　　检测内网机器端口
　　1.定义函数库mytools.py
#-*- coding:utf-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.header import Header
def sendemail(sender，receiver，subject，content，smtpserver，smtpuser，smtppass):
msg = MIMEText(content，'html'，'utf-8')#中文需参数‘utf-8'，单字节字符不需要
msg['Subject'] = Header(subject， 'utf-8')
msg['From'] = '<%s>' % sender
msg['To'] = ";".join(receiver)
try:
smtp = smtplib.SMTP()
smtp.connect(smtpserver)
smtp.login(smtpuser， smtppass)
smtp.sendmail(sender， receiver， msg.as_string())
smtp.quit()
except Exception，e:
print e
　　2. 实现端口扫描的程序，单线程版本nmscan.py
# !/usr/bin/python
# -*- coding:utf-8 -*-
import nmap
import re
import mytools as tool
import sys
reload(sys)
sys.setdefaultencoding('utf8')
def nmScan(hostlist， portrange， whitelist):
p = re.compile("^(d*)-(d*)$")
if type(hostlist) != list:
help()
portmatch = re.match(p， portrange)
if not portmatch:
help()
l = []
for host in hostlist:
result = ''
nm = nmap.PortScanner()
tmp = nm.scan(host， portrange)
result = result + "<h2>ip地址:%s 主机名:[%s]  ......  %s</h2><hr>" % (
host， tmp['scan'][host]['hostname']， tmp['scan'][host]['status']['state'])
try:
ports = tmp['scan'][host]['tcp'].keys()
except KeyError， e:
if whitelist:
whitestr = '，'.join(whitelist)
result = result + "未扫到开放端口!请检查%s端口对应的服务状态" % whitestr
else:
result = result + "扫描结果正常，无暴漏端口"
for port in ports:
info = ''
if port not in whitelist:
info = '<strong><font color=red>Alert:非预期端口</font><strong>&nbsp;&nbsp;'
else:
info = '<strong><font color=green>Info:正常开放端口</font><strong>&nbsp;&nbsp;'
portinfo = "%s <strong>port</strong> : %s &nbsp;&nbsp;<strong>state</strong> : %s &nbsp;&nbsp;<strong>product<strong/> : %s <br>" % (
info， port， tmp['scan'][host]['tcp'][port]['state']，
tmp['scan'][host]['tcp'][port]['product'])
result = result + portinfo
l.append([host， str(result)])
return l
def help():
print "Usage: nmScan(['127.0.0.1'，]，'0-65535')"
if __name__ == "__main__":
hostlist = ['10.10.10.10'， '10.10.10.11']
portrange = '0-65535'
whitelist = [80， 443]
l = nmScan(hostlist， portrange， whitelist)
sender = '75501664@qq.com'
receiver = ['zhangyanlin8851@163.com'， '877986976@qq.com']
subject = '服务器端口扫描'
smtpserver = 'smtp.exmail.qq.com'
smtpuser = 'zhangyanlin8851@163.cn'
smtppass = 'linuxidc163'
mailcontent = ''
for i in range(len(l)):
mailcontent = mailcontent + l[i][1]
tool.sendemail(sender， receiver， subject， mailcontent， smtpserver， smtpuser， smtppass)
　　3.多线程版本
# !/usr/bin/python
# -*- coding:utf-8 -*-
import nmap
import re
import mytools as tool
import sys
from multiprocessing import Pool
from functools import partial
reload(sys)
sys.setdefaultencoding('utf8')
def nmScan(host， portrange， whitelist):
p = re.compile("^(d*)-(d*)$")
# if type(hostlist) != list:
#    help()
portmatch = re.match(p， portrange)
if not portmatch:
help()
if host == '121.42.32.172':
whitelist = [25， ]
result = ''
nm = nmap.PortScanner()
tmp = nm.scan(host， portrange)
result = result + "<h2>ip地址:%s 主机名:[%s]  ......  %s</h2><hr>" % (
host， tmp['scan'][host]['hostname']， tmp['scan'][host]['status']['state'])
try:
ports = tmp['scan'][host]['tcp'].keys()
for port in ports:
info = ''
if port not in whitelist:
info = '<strong><font color=red>Alert:非预期端口</font><strong>&nbsp;&nbsp;'
else:

portinfo = "%s <strong>port</strong> : %s &nbsp;&nbsp;<strong>state</strong> : %s &nbsp;&nbsp;<strong>product<strong/> : %s <br>" % (
info， port， tmp['scan'][host]['tcp'][port]['state']， tmp['scan'][host]['tcp'][port]['product'])
result = result + portinfo
except KeyError， e:
if whitelist:
whitestr = '，'.join(whitelist)
result = result + "未扫到开放端口!请检查%s端口对应的服务状态" % whitestr
else:

return result
def help():
