Python loop to monitor remote ports

This article illustrates a python loop monitoring method for remote ports. Share with you for your reference. The details are as follows:

With one IP address and port number per line in ip.txt, the code can iterate to monitor whether the specified port of these IP addresses is normal

#!/usr/bin/env python
# -*- coding: gbk -*-
import socket,time
while 1:
  file_obj = open('ip.txt')
  for line in file_obj:
    try:
      sc=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
      ip = line.split()[0]
      port = int(line.split()[1])
      print ip,port
      # Set timeout time ( 0.0 ) 
      sc.settimeout(2)
      sc.connect((ip,port))
      timenow=time.localtime()
      datenow = time.strftime('%Y-%m-%d %H:%M:%S', timenow)
      logstr="%s:%s  The connection is successful ->%s n" %(ip,port,datenow)
      print logstr
      sc.close()
    except:
      file = open("log.txt", "a")
      timenow=time.localtime()
      datenow = time.strftime('%Y-%m-%d %H:%M:%S', timenow)
      logstr="%s:%s  The connection fails ->%s n" %(ip,port,datenow)
      print logstr
      file.write(logstr)
      file.close()
  print "sleep 10....."
  time.sleep(10)

File in ip.txt format:

192.168.1.100 33001
192.168.1.101 33001
