python循环监控远程端口的代码详解编程语言

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 
# -*- 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 
            #设置超时时间（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 连接成功->%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 连接失败->%s /n" %(ip,port,datenow) 
            print logstr 
            file.write(logstr) 
            file.close() 
    print "sleep 10....." 
    time.sleep(10)
