Server/Client application TimeoutError on LAN

问题

I have two programs: server.py and client.py. I need to be able to use server.py in my main PC, and client.py from my laptop. When I run them, I get the following error from client.py:

TimeoutError: [WinError 10060]

I have disabled firewalls in both my PC (that runs Windows 7) and my laptop (that runs Windows 8).

How do I get them to connect?

Some things that I have tried:

Creating Firewall port rules, on the PC.
Disabling the firewall in both computers.
Using different ports.
Changing the server address from "localhost" to socket.gethostname(), this changes the error from TimeoutError to ConnectionRefusedError.

The IP for my PC is 192.168.0.2, and I am sure of this because I have an Apache server running in port 80, and that one works (I can access that from my laptop).

Python versions: PC: 3.5.2, Laptop: 3.4.1

Code

server.py:

import socket
import threading

server_port = 2569
server_address = "localhost"

class ClientThread(threading.Thread):
    def __init__(self, client_info):
        super(ClientThread, self).__init__()
        self.client_info = client_info

    def run(self):
        socket = self.client_info[0]
        bytes_received = socket.recv(100)
        print(bytes_received.decode("utf-8"))

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind((server_address, server_port))
server_socket.listen(5)

while True:
    new_client = server_socket.accept()
    ClientThread(new_client).run()

client.py:

import socket

server_port = 2569
server_address = "192.168.0.2"

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.connect((server_address, server_port))
server_socket.send(b"message")

回答1:

You just need to change the localhost or socket.gethostname() in the server.py/client.py scripts to the actual internal ip address of the server. Then it will work!

If you want to learn more why this happens I recommend reading this post which explains in deep the differences between localhost/127.0.0.1 and the internal ip of a machine, which are falsely considered to be the same thing, but in fact they are not.
