a simple tcp server sample

[Tzury Bar Yochay]

hi, the following sample (from docs.python.org) is a server that can
actually serve only single client at a time.

In my case I need a simple server that can serve more than one client.
I couldn't find an example on how to do that and be glad to get a
hint.

Thanks in advance

import socket

HOST = '127.0.0.1' # Symbolic name meaning the local host
PORT = 50007 # Arbitrary non-privileged port

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()

print 'Connected by', addr

while 1:
data = conn.recv(1024)
if not data:
break
conn.send(data)

conn.close()

That's when it stops being simple. You'll need to spawn threads or
fork off separate processes to do that.

See the SocketServer module, both the documentation and the source code.

I think the authors of Twisted would be very surprised to find out that
their framework can only serve one client at a time.

Even simpler, use Twisted:

I am afraid Twisted is not the right choice in my case. I am looking
for smaller, simpler and minimal server sample.

I firstly looked at this module and its __doc__, yet I still need an
'hello world' sample. and couldn't get it straight how can I write my
own hello world sample with SocketServer objects.

here is its:
# a simple tcp server

import SocketServer


class EchoRequestHandler(SocketServer.BaseRequestHandler ):
def setup(self):
print self.client_address, 'connected!'
self.request.send('hi ' + str(self.client_address) + '\n')

def handle(self):
while 1:
data = self.request.recv(1024)
self.request.send(data)
if data.strip() == 'bye':
return

def finish(self):
print self.client_address, 'disconnected!'
self.request.send('bye ' + str(self.client_address) + '\n')

#server host is a tuple ('host', port)
server = SocketServer.ThreadingTCPServer(('', 50008),
EchoRequestHandler)
server.serve_forever()
