1、ping连通性测试
1 #!/usr/bin/env python 2 #-*- coding: utf-8 -*- 3 import os,sys,re 4 import subprocess 5 6 def NetCheck(ip): 7 try: 8 p = subprocess.Popen(["ping -c 1 -W 1 "+ ip],stdout=subprocess.PIPE,stderr=subprocess.PIPE,shell=True) 9 out=p.stdout.read() 10 #err=p.stderr.read() 11 regex=re.compile('100% packet loss') 12 #print out 13 #print regex 14 #print err 15 if len(regex.findall(out)) == 0: 16 print ip + ': host up' 17 return 'UP' 18 else: 19 print ip + ': host down' 20 return 'DOWN' 21 except: 22 print 'NetCheck work error!' 23 return 'ERR'
ip1="2.3.2.2"
domain1="www.baidu.com"
NetCheck(ip1)
NetCheck(domain1)
或者：连通返回0，不通返回512
1 >>> ret1=os.system('ping -c 2 -W 1 114.114.114.14') 2 PING 114.114.114.14 (114.114.114.14): 56 data bytes 3 Request timeout for icmp_seq 0 4 5 --- 114.114.114.14 ping statistics --- 6 2 packets transmitted, 0 packets received, 100.0% packet loss 7 >>> ret1 8 512 9 >>> ret1=os.system('ping -c 2 -W 1 114.114.114.114') 10 PING 114.114.114.114 (114.114.114.114): 56 data bytes 11 12 --- 114.114.114.114 ping statistics --- 13 2 packets transmitted, 2 packets received, 0.0% packet loss, 2 packets out of wait time 14 round-trip min/avg/max/stddev = 27.535/31.029/34.523/3.494 ms 15 >>> ret1 16 0 17 >>>
2、http(s)连通性测试
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import urllib2
1 def http_validate(target_url): 2 try: 3 urllib2.urlopen(target_host) 4 return True 5 except: 6 return False 7 8 9 url1 = 'https://www.baidu.com' 10 url2 = 'http://www.baudi.com' 11 12 if http_validate(url1): 13 print "可达" 14 else: 15 print "不可达" 16 17 if http_validate(url2): 18 print "可达" 19 else: 20 print "不可达"
