Python2 socket TCPServer 多线程并发 超时关闭

在阿里云上测试过,可以直接使用。
用IP和端口发送数据,会返回echo:+接收到的数据

#coding=utf-8
import socket
import threading,getopt,sys,string
list=50
port=8001

opts, args = getopt.getopt(sys.argv[1:], "hp:l:",["help","port=","list="])
#设置默认的最大连接数和端口号,在没有使用命令传入参数的时候将使用默认的值

def usage():
    print """
    -h --help             print the help
    -l --list             Maximum number of connections
    -p --port             To monitor the port number  
    """
for op, value in opts:
    if op in ("-l","--list"):
        list = string.atol(value)
    elif op in ("-p","--port"):
        port = string.atol(value)
    elif op in ("-h"):
        usage()
        sys.exit()

def jonnyS(client, address):
    try:
    #设置超时时间
        client.settimeout(30)
        while True:

            print"connect by",address
            print buf
        #将接收到的信息原样的返回到客户端中
            client.send("echo:"+buf)
    #超时后显示退出

    #关闭与客户端的连接
    client.close()
