Client Server System with Sockets



Now, let's create a simple server system that accepts incoming connections and some data we type. A small warning: this is highly unlikely to work well on Windows operating systems. You will still get some output, but it will likely be for every key pressed.

import socket
import sys
from _thread import *

host = ''
port = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

try:
    s.bind((host, port))
except socket.error as e:
    print(str(e))

s.listen(5)
print('Waiting for a connection.')
def threaded_client(conn):
    conn.send(str.encode('Welcome, type your info\n'))

    while True:
        data = conn.recv(2048)
        reply = 'Server output: '+ data.decode('utf-8')
        if not data:
            break
        conn.sendall(str.encode(reply))
    conn.close()


while True:

    conn, addr = s.accept()
    print('connected to: '+addr[0]+':'+str(addr[1]))

    start_new_thread(threaded_client,(conn,))
