Python中的简单telnet聊天服务器

Question

我正在阅读关于套接字的文章并找到了一个很好的练习:一个简单的聊天服务器回应输入.这似乎是一个常见的练习,我找到了几个例子,如chatserver5.py和一些SO问题.问题是我只能在使用时连接telnet localhost 51234而不能连接telnet 192.168.1.3 51234(其中192.168.1.3是我的"服务器"的网络IP).不用说,我无法从网络上的另一台机器连接.我得到以下输出:

Trying 192.168.1.3...
telnet: connect to address 192.168.1.3: Connection refused
telnet: Unable to connect to remote host

这是我的代码:

import socket, threading

HOST = '127.0.0.1'
PORT = 51234 

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(4)
clients = [] #list of clients connected
lock = threading.Lock()


class chatServer(threading.Thread):
    def __init__(self, (socket,address)):
        threading.Thread.__init__(self)
        self.socket = socket
        self.address= address

    def run(self):
        lock.acquire()
        clients.append(self)
        lock.release()
        print '%s:%s connected.' % self.address
        while True:
            data = self.socket.recv(1024)
            if not data:
                break
            for c in clients:
                c.socket.send(data)
        self.socket.close()
        print '%s:%s disconnected.' % self.address
        lock.acquire()
        clients.remove(self)
        lock.release()

while True: # wait for socket to connect
    # send socket to chatserver and start monitoring
    chatServer(s.accept()).start()

我没有使用telnet或套接字的经验.为什么我无法远程连接,如何解决这个问题呢？

如果你设置HOST = '',那么你将能够从任何地方连接.现在,你绑定它127.0.0.1,它是相同的localhost.
