Python: Echo Server

Simple Echo Server

Sebuah simple echo server (echoserver-simple.py):

#!/usr/bin/env python

import socket 

host = 
port = 50000
backlog = 5
size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen(backlog)
while 1:
    client, address = s.accept()
    data = client.recv(size)
    if data:
        client.send(data)
    client.close() 

Sebuah Echo Client Sederhana

Simple echo client (echoclient-simple.py):

#!/usr/bin/env python
 
import socket 

host = 'localhost'
port = 50000
size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host,port))
s.send('Hello, world')
data = s.recv(size)
s.close()
print 'Received:', data  

Alternatif Test menggunakan nc

nc ipserver 5000 "tulisan yang dikirim"
