I figured out how to create a very simple socket server. Though this socket server does exactly nothing special. I can however get it to send only one line of data back to the telnet client.
You need two nested loops - an outer loop to accept the connection and an inner loop to proces the data. The way you have it now, it processes one line, then blocks waiting for a new connection.
Take a look at example 19-1 in Python in a Nutshell. You can download it here: http://examples.oreilly.com/pythonian/
You might also be interested in example 19-5 which does the same thing using the SocketServer module and example 19-9 which uses Twisted.

import socket ###################### HOST = "" PORT = 4000 ######################
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM) s.bind((HOST,PORT)) s.listen(5) def log(): a = addr b = str(a) logfile = open("logfile.log", "a+") logfile.write("Attempting connection from "+b+"\n") logfile.close()
while 1: conn, addr = s.accept() data = conn.recv(1024) if not data: break else: conn.send(data)
How can I make it so that when a client sends the word hello the server will write back hello, how are you?.
