使用python 检查存活主机

这里的设备对存活状态不是很敏感，就使用了脚本来检测存活状态，之前用shell做了一个，实现的功能是使用Ping命令检测服务器存活，不在线会将不在线的服务器及IP通过邮件发送提醒，现在在学习python，改了一个python版本。需要检测的主机我存储在/scrip/host中，格式为:

HOST  IP

好了，废话少说，上脚本：

#coding=utf-8
import subprocess
import os,time,sys,re
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
server=smtplib.SMTP(\'smtp.126.com\')
start_Time=time.strftime(\'%Y-%m-%d %H:%M:%S\',time.localtime(time.time()))
mj=open(\'/scrip/host\',\'r\')
mi=open(\'/scrip/text\',\'w\')
mihost=mj.readlines()
mj.close()
online=[]
i=0
for i in range(len(mihost)):
  host=mihost[i][0:14].strip()
  ip=mihost[i][14:].strip()
  p = subprocess.Popen([\"ping -c 1 -i 0.2 -W 3 \"+ ip],
              stdin = subprocess.PIPE,
              stdout = subprocess.PIPE,
              stderr = subprocess.PIPE,
              shell = True)
  out = p.stdout.read()
  regex = re.compile(\"time=\\d*\", re.IGNORECASE | re.MULTILINE)
  if len(regex.findall(out)) > 0:
     online.append(host)
  else:
    fail_host =host + \' \\t\'+ ip
    mi.write(fail_host)
    mi.write(\'\\n\')
mi.close()
fail=open(\'/scrip/text\',\'r\')
number=fail.readlines()
fail_host=\'\'.join(number)
context = \'Scan Time:\' + \'\\t \'*2 +\' \' *3 + start_Time +\'\\n\'+ \'Not Online Devices:\' +\'\\t\'+ repr(len(number)) +\'\\n\'+ \'\\n\' +\'HOST\' + \' \'*12 + \'I P\' + \'\\n\' + fail_host
msg = MIMEMultipart(\'alternative\')
msg[\'Subject\'] = \'Not Online Device\'
part = MIMEText(context, \'plain\', \'utf-8\')
msg.attach(part)
server=smtplib.SMTP(\'smtp.126.com\')
server.login(\"邮箱用户名\",\"邮箱密码\")
maillist=[\'接收邮箱\',]
server.sendmail(\"发送邮箱地址\",maillist,msg.as_string())

运行的结果：
