使用python检测主机存活端口及检查存活主机

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：
