windows7 python 指定源组播 10049_试图绑定到特定的外部ip :: [Errno 10049]请求的地址在其上下文中无效无法打开socket-（python 2.7）…[通俗易懂]

socket.INADDR_ANY 等于 socket.bind(‘0.0.0.0’)

如果绑定到“0.0.0.0”可以监听所有接口(可用)

Moxa TCP示例：

import socket,time

import thread

#Example client

class _client :

def __init__(self):

self.status = False

def run(self,clientsock,addr):

while 1 :

try:

data = clientsock.recv(BUFF)

if data :

#do something with data

time.sleep(.1)

if self.status == False:

clientsock.close()

break

clientsock.send(next_query)

except Exception,e :

print e

break

client = _client()

ADDR = (“0.0.0.0”, 45500) #so you need port how to decode raw socket data ?

serversock = socket(AF_INET, SOCK_STREAM)

serversock.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)

serversock.setsockopt(IPPROTO_TCP, TCP_NODELAY, 1)#gain 50ms tcp delay

serversock.bind(ADDR)

serversock.listen(10)

While True :

clientsock, addr = serversock.accept()

if addr[0] == device_1_IP:

client.status = True

#start device1 thread(moxa is TCP client mode)

thread.start_new_thread(client.run, (clientsock, addr))

#if client.status = False you will be close connection.

But my offer is “use moxa with TCP server mode”

我使用4x5450i 3×5250超过120设备没有任何错误 .
