1.单线程ping所知道的ip地址

 在脚本所在目录下新建ip_list.txt和ip_False.txt

 其中ip_list.txt是存放所已知的ip地址（每行只写一个ip，最后一个ip也需要换行）

脚本未做兼容处理，只使用于window系统

import sys
import subprocess
import os
import time

'''
    检测设备运行是否正常
    待检测IP添加在ip_list.txt
    每次不正常IP追加在文件ip_False.txt

reload(sys)
sys.setdefaultencoding('utf-8')

#获取当前工作路径
def getCurrendPath():
    return os.getcwd()

#调用ping命令，判断IP是否正常
def subPing():
    ip_list = []
    _path = getCurrendPath()
    ip_lists = _path + r'\ip_list.txt'
    ip_False = _path + r'\ip_False.txt'
    for line in open(ip_lists):
        ret = subprocess.call("ping %s -n 3" % line,shell=True,stdin=subprocess.PIPE,stdout=subprocess.PIPE)
        if ret == 1:
            ip = '%s is not alive, there have some problem' % line[:-1]
            ip_list.append(ip)

    if ip_list:
        nowTime = getDataTime()
        errorFile = open(ip_False,'a')
        errorFile.write(u"时间"+nowTime+'\n')
        for errorIP in ip_list:
            errorFile.write(errorIP+'\n')
        errorFile.close()
        print '''

    else:
        print '''

    return time.strftime('%Y-%m-%d',time.localtime(time.time()))

    subPing()

2.多线程扫描内网存活主机

运行脚本格式： python IPscanner.py [本机ip]

脚本可用在所有系统上

#!/usr/bin/env/python
#_*_coding:utf-8_*_
#Data:17-09-03
#Auther:苏莫
#Link:http://blog.csdn.net/lingluofengzang/
#PythonVersion:python2.7
#filename:IPscanner.py

import os
import sys
import time
import threading

reload(sys)
sys.setdefaultencoding("utf-8")

# 获取脚本运行的系统
def get_system():
    if os.name == 'nt':
        return 'n'
    else:
        return 'c'

def ping_ip(ip_str):
    shell = ['ping','-{op}'.format(op=get_system()),'1',ip_str]
    output = os.popen(' '.join(shell)).readlines()
    for line in list(output):
        if not line:
            continue
        if str(line).upper().find('TTL') >= 0:
            print "ip: %s is ok " % ip_str
            break

def find_ip(ip_prefix):
    for i in xrange(1,256):
        ip = '%s.%s' % (ip_prefix,i)
        threading.Thread(target = ping_ip , args = (ip , )).start()
        time.sleep(0.3)

if __name__ == '__main__':
    cmd = sys.argv[1:]
    args = ''.join(cmd)

    ip_prefix = '.'.join(args.split('.')[:-1])
    find_ip(ip_prefix)
