Python网络连通性检测：

[root@skatedb55 ~]# vi checkping.py #!/usr/bin/env python #-*- coding: utf-8 -*- #Author:Skate

import os,sys,re import subprocess

def NetCheck(ip):    try:     p = subprocess.Popen(["ping -c 1 -w 1 "+ ip],stdout=subprocess.PIPE,stderr=subprocess.PIPE,shell=True)     out=p.stdout.read()     #err=p.stderr.read()     regex=re.compile('100% packet loss')     #print out     #print regex     #print err     if len(regex.findall(out)) == 0:         print ip + ': host up'         return 'UP'     else:         print ip + ': host down'         return 'DOWN'    except:     print 'NetCheck work error!'     return 'ERR'

if __name__ == '__main__':     NetCheck('10.20.0.56')     NetCheck('10.10.0.56')     NetCheck('10.10.0')

运行结果：

[root@skatedb55 ~]# python checkping.py 10.20.0.56: host up UP 10.10.0.56: host down 10.10.0: host down
