python 服务器状态探测3种方法

1、关键字分析 

import os 

#https网站加-k

cmd = ''' (curl --no-keepalive --connect-timeout 18 --stderr - '''+urls[i]+''' | grep '''+urls[i+1]+''' >/dev/null) && echo 'ok' '''

os.popen3(cmd) 

2、 http head状态测试
import urllib2

 try:

       urllib2.urlopen(urls[i],context=context)

  except Exception, e:

... 

3、端口探测

import os 

cmd="nmap -sT -n -p 80,3389 --max-rtt-timeout 1 --max-scan-delay 1ms --host-timeout 2 " + server

(si, so, se) = os.popen3(cmd) 

t=so.readlines() 

if line.find('80')>=0 and line.find('open')>=0:

...
