用python实现socket聊天室再次遇到问题

Question

用python的socket库实现多人聊天室，但是只能在自己主机上打开多个客户端进行聊天，用别人的电脑输入我的电脑的IP地址却连不上我的服务端，这是为什么？
这是服务端

import socket
import threading
import socketserver

nick = ''

data = ''


def Notifyall(sentence):
    global data
    if condition.acquire():
        data = sentence
        condition.notifyAll()
        condition.release()


def severs_send(conn, nick):
    global data
    while True:
        if condition.acquire():
            condition.wait()
            if data:
                try:
                    conn.send(data.encode('utf-8'))
                    condition.release()
                except:
                    condition.release()
                    return


def severs_accept(conn, nick):
    while True:
        try:
            indata = conn.recv(1024).decode('utf-8')
            if not indata:
                conn.close()
                return
            Notifyall(indata)
            print(data)
        except:
            Notifyall(nick.decode() + 'error')
            print(data)
            return


condition = threading.Condition()
# ip = input("input the server ip address:")
port = 8888
sock = socket.socket()
print('socket created')
sock.bind((nick, port))
sock.listen(5)
print("socket new listening")

while True:
    conn, address = sock.accept()
    print('connect with' + address[0] + ':' + str(address[1]))
    nick = conn.recv(1024)
    Notifyall('WELCOME' + str(nick) + 'to this chatroom!')
    print(data)
    conn.send(data.encode(encoding='utf_8', errors='strict'))
    threading.Thread(target=severs_accept, args=(conn, nick)).start()
    threading.Thread(target=severs_send, args=(conn, nick)).start()

这是客户端

import socket
import threading

outstring=''
nick=''
instring=''

def client_send(sock):
    global outstring
    while True:
        outstring=input()
        outstring=nick+':'+outstring
        sock.send(outstring.encode(encoding='utf_8', errors='strict'))

def client_accept(sock):
    global instring
    while True:
        try:
            instring=sock.recv(1024)
            if not instring:
                break
            else:
                print(instring)
        except:
            break

nick=input("input your nickname:")

ip=input("input the server ip address:")
port=8888
sock=socket.socket(socket.AF_INET)
sock.connect((ip,port))
sock.send(nick.encode(encoding='utf_8', errors='strict'))

threading.Thread(target=client_send,args=(sock,)).start()
threading.Thread(target=client_accept,args=(sock,)).start()

代码是OK的，请检查下操作系统的防火墙是否对外开放了8888端口
