python循环监控远程端口的代码_python

在ip.txt中每行一个ip地址和端口号，代码可循环监控这些ip地址的指定端口是否正常

#!/usr/bin/env python

import socket,time

    file_obj = open('ip.txt')
    for line in file_obj:

            ip = line.split()[0]
            port = int(line.split()[1])
            print ip,port
            #设置超时时间（0.0）
            sc.settimeout(2)
            sc.connect((ip,port))
