Trying to implement some kind of synergy on python using PyAutoGui and socket communication.
The idea is to control mouse and keyboard of another computer on LAN by using mouse/keyboard of a server computer.
By now it's only mouse movement implementaion.
Here are some classes:
Server part:
class Server:
def __init__(self):
self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.ip = get_ip()
self.port = 3000
self.transfer_mod = False
self.client_address = ""
def start(self):
print("Started server with ip: {}".format(self.ip))
self.s.bind((self.ip, self.port))
self.get_connection()
def get_connection(self):
print("Waiting for connection...")
while True:
request, self.client_address = self.s.recvfrom(4096)
if request:
self.s.sendto(request, self.client_address)
print("{} connected!".format(self.client_address))
break
def enable_transfer(self):
print("Transfer to {} enabled".format(self.client_address))
self.transfer_mod = True
transfer_thread = threading.Thread(target=self.transfer_mouse)
transfer_thread.start()
def disable_transfer(self):
print("Transfer to {} disabled".format(self.client_address))
self.transfer_mod = False
def transfer_mouse(self):
previous_pos = (-1, -1)
while self.transfer_mod:
pos = pyautogui.position()
if pos != previous_pos:
data = pickle.dumps(pos)
self.s.sendto(data, self.client_address)
sleep(0.1)
previous_pos = pos
def close(self):
self.disable_transfer()
self.s.close()
Client part:
class Client:
def __init__(self):
self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.port = 3000
self.connection = False
def connect(self, server_ip):
request = bytes("Request","utf-8")
self.s.sendto(request, (server_ip, self.port))
received, address = self.s.recvfrom(4096)
if received == request:
print("Connected to {}".format(server_ip))
self.connection = True
threading.Thread(target=self.receive_data).start()
def receive_data(self):
while self.connection:
data, server = self.s.recvfrom(4096)
pos = pickle.loads(data)
self.control_mouse(pos)
def disconnect(self):
print("Disconnected from the server")
self.connection = False
def control_mouse(self, position):
pyautogui.moveTo(position[0], position[1])
def close(self):
self.disconnect()
self.s.close()
So, the problem of that is the speed of mouse movement on client computer is so low. It seems there are too many exceed packets or something like that. So, the question itself: Is it a good way of implementing this idea, if yes, what's the problem of that script, if no, any advises on how to do it more properly?

How to put packet in socket, when I use socket.recv? I made my TCP server to client network. But in the code, I want to put packet in self.soc.recv(1024). How can I put the packet in socket?
Here's my code
#서버 코드
import threading, socket
class Room: #채팅방
def __init__(self):
self.clients = []#접속한 클라이언트를 담당하는 ChatClient 객체 저장
def addClient(self, c):#클라이언트 하나를 채팅방에 추가
self.clients.append(c)
def delClent(self, c):#클라이언트 하나를 채팅방에서 삭제
self.clients.remove(c)
def sendAllClients(self, msg):
for c in self.clients:
c.sendMsg(msg)
class ChatClient:#텔레 마케터: 클라이언트 1명이 전송한 메시지를 받고, 받은 메시지를 다시 되돌려줌
def __init__(self, id, soc, r):
self.id = id #클라이언트 id
self.soc = soc #담당 클라이언트와 1:1 통신할 소켓
self.room = r #채팅방 객체
def recvMsg(self):
while True:
data = self.soc.recv(1024)
msg = data.decode()
if msg == '/stop':
self.sendMsg(msg) # 클라이언트쪽의 리시브 쓰레드 종료하라고..
print(self.id,'님 퇴장')
break
msg = self.id+': ' + msg
self.room.sendAllClients(msg)
self.room.delClent(self)
self.room.sendAllClients(self.id+'님이 퇴장하셨습니다.')
def sendMsg(self, msg): #담당한 클라이언트 1명에게만 메시지 전송
self.soc.sendall(msg.encode(encoding='utf-8'))
def run(self):
t = threading.Thread(target=self.recvMsg, args=())
t.start()
class ServerMain:
ip = '192.168.55.232'
port = 2500
def __init__(self):
self.room = Room()
self.server_soc = None
def open(self):
self.server_soc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.server_soc.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
self.server_soc.bind((ServerMain.ip, ServerMain.port))
self.server_soc.listen()
def run(self):
self.open()
print('채팅 서버 시작')
while True:
c_soc, addr = self.server_soc.accept()
print(addr)
msg = '사용할 id:'
c_soc.sendall(msg.encode(encoding='utf-8'))
msg = c_soc.recv(1024)
id = msg.decode()
cc = ChatClient(id, c_soc, self.room)
self.room.addClient(cc)
cc.run()
print('클라이언트', id, '채팅 시작')
def main():
server = ServerMain()
server.run()

I got my packet by wireshark, and I want put packet in soket.recv(). Is any solution that I can get?
my server sends objects much faster than the client receives. That's why the client receives the objects that were sent 10 seconds ago because the client has to receive every object that is in the queue. So my question is: How do I slow the server down or make my client receiving faster?
Edit: I added time.sleep(0.1) to the server but is there a more efficient way?
This is my Network class:
import socket
import pickle
class Network:
def __init__(self):
self.client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.server = "192.168.1.15"
self.port = 5555
self.addr = (self.server, self.port)
self.player = self.connect()
def get_player(self):
return self.player
def connect(self):
try:
self.client.connect(self.addr)
except:
pass
def send_object(self, data):
self.client.send(pickle.dumps(data))
def get_object(self):
return pickle.loads(self.client.recv(1024))
def send_msg(self, data):
self.client.send(bytes(data, "utf-8"))
def get_msg(self):
return self.client.recv(1024).decode("utf-8")
and my server when it's sending:
p_count = conn.recv(1024).decode("utf-8")
if p_count:
games.append(Game(game_id, int(p_count), ip))
game_id += 1
while True:
conn.send(pickle.dumps(games[-1]))
and my client when it's receiving:
def update(self):
global bg_surface
try:
self.game = n.get_object()
self.player_in = self.game.players_ready
bg_surface = pygame.image.load('./bilder/background3.jpg').convert()
bg_surface = pygame.transform.scale(bg_surface, (screen_width, screen_height))
self.warte_text = Label(f"Warte auf Spieler {self.player_in}/{self.player_amount}", 20, (screen_width // 2, screen_height // 2 * 0.25), (255, 0, 0))
self.warte_text.update(bg_surface)
except:
pass
The efficient way to handle this is to have your server call select() or poll() on the socket to find out when the socket has room in its outgoing-data-buffer (and optionally block until there is room) and only generate and send() data to the socket when the socket has indicated it is ready-for-write. That way your server-thread doesn't get blocked waiting for the client to read data, no matter how slow the client is at reading.
I'm trying to build a socket and I want to print an object of clients, but for some reason whenever I connect it just returns empty {}
I'm new to Python and would like some insight

self.sock.sendall("Welcome master".encode())

I have set up a socket server with a client and a host.
It works fine until the client has disconnected, with both .shutdown() and .close().
When I then launch the client again, it can't connect.
I presume this is not because of how I've written my code but rather what I haven't written.
How do I make the server truly disconnect the client's connection so that it can connect again?

This script works absolutely fine across a home network, with 192.168... internal IP addresses.
On a school network, with 172... IP addresses, it doesn't seem to work. There is no connection error, but messages are not sent or received, with the exception of if there are two instances of the application being run on the same computer with the same internal IP address, in which case the program works flawlessly.
I am very new to sockets and this sort of networking, so I am wondering if anyone can point out to me why this is the case. Might it be the difference in IP addresses, for example?
Thank you in advance.
I see you're connecting on port 23647 - you may not have access to this on your school network. Check if this port has traffic enabled. see: Port Forwarding for details.
Something like: this site/tool may allow you to check quickly.
