这篇文章主要介绍了使用python检测主机存活端口及检查存活主机的相关资料,需要的朋友可以参考下

监测主机存活的端口

									#!/usr/bin/env python

									# coding-utf

									import argparse

									import socket

									import sys

									#author: wolf_ribble

									def scan_ports(host,start_port,end_port):

									  """Scan remote hosts"""

									  try:

									    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

									  except socket.error,error_msg:

									    print 'Socket creation failed.Error code:' + str(error_msg[]) + 'Erroe message:' + error_msg[]

									    sys.exit()

									  try:

									    remote_ip = socket.gethostbyname(host)

									  except socket.error,error_msg:

									    print error_msg

									    sys.exit()

									  end_port +=

									  for port in range(start_port,end_port):

									    try:

									      sock.connect((remote_ip,port))

									      print 'Port' + str(port) + 'is ipen'

									      sock.close()

									      sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

									    except socket.error,error_msg:

									      #print error_msg

									      pass

									if __name__ == '__main__':

									  parser = argparse.ArgumentParser(description='remote port scaner')

									  parser.add_argument('--host',action="store",dest="host",default='www.wealink.com')

									  parser.add_argument('--start-port',action="store",dest="start_port",default='',type=int)

									  parser.add_argument('--end-port',action="store",dest="end_port",default='',type=int)

									  given_args = parser.parse_args()

									  host, start_port ,end_start = given_args.host , given_args.start_port,given_args.end_port

									  scan_ports(host,start_port,end_start)

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())
