Python检查远程服务和端口的方法

使用Python脚本，检测远程服务和端口是否连通，可以用如下代码片断实现

#!/usr/bin/python
# _*_ coding: UTF-8 _*_

import socket
import threading
import time

#服务和端口放在list中
service = [\'mixcztdb.erp3.crland.com.cn 1526\', \'ztcommon.crland.cn 8081\',
           \'ztshop.crland.cn 80\', \'opera.crland.com.cn 80\',
           \'opera.crland.cn 80\', \'invest.saas.crland.com.cn 80\',
           \'zt_rediscol1.erp3.crland.com.cn 7001\', \'zt_rediscol1.erp3.crland.com.cn 7002\',
           \'zt_rediscol2.erp3.crland.com.cn 7001\', \'zt_rediscol2.erp3.crland.com.cn 7002\',
           \'zt_rediscol3.erp3.crland.com.cn 7001\', \'zt_rediscol3.erp3.crland.com.cn 7002\']

\'\'\'
用socket连接
\'\'\'
def socketconnect(addr, port):
    try:
        sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sk.settimeout(2)
        sk.connect((addr, int(port)))
        # print \'connect to \' + addr + \' \' + port + \' success\'
    except socket.error, e:
        print \'connect to \' + addr + \' \' + port + \' timed out\'
    sk.close()


\'\'\'
取service中的地址和端口
\'\'\'
def check():
    for every in service:
        addr = every.split()
        socketconnect(addr[0], addr[1])

\'\'\'
main方法
\'\'\'

if __name__ == \'__main__\':
    threads = [threading.Thread(target=check())]
    map(lambda x: x.start(), threads)

运行结果，输出了不通的服务地址信息

connect to mixcztdb.erp3.crland.com.cn 1526 timed out
connect to zt_rediscol1.erp3.crland.com.cn 7001 timed out
