Use Python to detect host survival ports and check for surviving hosts

Using Python to check for surviving hosts

The equipment here is not very sensitive to the survival status, the use of the script to detect the survival state, before using the shell to do one, the implementation of the function is to use the ping command to detect the server to survive, not the line will not be online server and IP sent by email reminders, and now learning Python, Changed to a python version. The host I want to detect is stored in/scrip/host in the format:

HOST IP

Well, nonsense less, on the script:

#coding =utf-8import subprocessimport os,time,sys,reimport smtplibfrom email.mime.text Import Mimetextfrom Email.mime.multipart import Mimemultipartserver=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=0for 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 (f Ail_host) mi.write (' \ n ') mi.close () fail=open ('/scrip/text ', ' R ') number=fail.readlines () fail_host= '.
