Question

我想在我的计算机和服务器（ubuntu）之间进行TCP通信。

服务器IP为203.246.114.176，其端口30000已打开。

服务器正在运行以下server.py：

import socket
import sys

# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Bind the socket to the port
server_address = ('localhost', 30000)
print >>sys.stderr, 'starting up on %s port %s' % server_address
sock.bind(server_address)

# Listen for incoming connections
sock.listen(1)

while True:
    # Wait for a connection
    print >>sys.stderr, 'waiting for a connection'
    connection, client_address = sock.accept()

    try:
        print >>sys.stderr, 'connection from', client_address

        # Receive the data in small chunks and retransmit it
        while True:
            data = connection.recv(16)
            print >>sys.stderr, 'received "%s"' % data
            if data:
                print >>sys.stderr, 'sending data back to the client'
                connection.sendall(data)
            else:
                print >>sys.stderr, 'no more data from', client_address
                break

    finally:
        # Clean up the connection
        connection.close()

我的电脑有client.py：

import socket
import sys

# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Connect the socket to the port where the server is listening
server_address = ('203.246.114.176', 30000)
print >>sys.stderr, 'connecting to %s port %s' % server_address
sock.connect(server_address)

try:

    # Send data
    message = 'This is the message.  It will be repeated.'
    print >>sys.stderr, 'sending "%s"' % message
    sock.sendall(message)

    # Look for the response
    amount_received = 0
    amount_expected = len(message)

    while amount_received < amount_expected:
        data = sock.recv(16)
        amount_received += len(data)
        print >>sys.stderr, 'received "%s"' % data

finally:
    print >>sys.stderr, 'closing socket'
    sock.close()

当我在服务器上运行时，输出如下：

starting up on localhost port 30000
waiting for a connection

，ufw状态如下：

但是我的电脑显示了这个输出：

C:\Users\user\Documents\notepad>python client.py
Traceback (most recent call last):
  File "client.py", line 7, in <module>
    s.connect((host, port))
  File "C:\Python27\lib\socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 10061]

怎么回事？我该怎么办？

帮助PLZ。

此行中的服务器出错：

server_address = ('localhost', 30000)

localhost通常为127.0.0.1，因此您没有按照您的想法将其约束到203.246.114.176。尝试使用

server_address = ('203.246.114.176', 30000)

获取此确切的IP地址，或

server_address = ('0.0.0.0', 30000)

监听所有活动接口。

如何使用服务器和我的计算机在Python中解决socket.error：[Errno 10061]
