SocketServer broadcast

[Olivier Hoarau]

Hello,

I have build a client/server application with the socket module. The
server mades UDP broadcasting and the client only reads UDP broadcast
messages. All work fine.
Now I want to use for the same thing the socketserver module, it's ok
for the client, but I don't succeed in making work the server :-((

Here is the client (which works)

import sys
import SocketServer

host='192.168.2 0.73'
PORT=10000

class BroadcastAcquis ition(SocketSer ver.UDPServer,
SocketServer.Th readingMixIn):
def __init__(self, address, handler):
self.allow_reus e_address = 1
SocketServer.UD PServer.__init_ _(self, address, handler)

class Handler(SocketS erver.DatagramR equestHandler):
def handle(self):
print self.packet

s = BroadcastAcquis ition(('', PORT), Handler)
s.serve_forever ()


And the server (doesn't work)

import sys
import time
import SocketServer

GROUP = '192.168.20.255 '
HOST='192.168.2 0.73'
PORT=10000

class Broadcast(Socke tServer.UDPServ er, SocketServer.Th readingMixIn):
def __init__(self, address, handler):
self.allow_reus e_address = 1
SocketServer.UD PServer.__init_ _(self, address, handler)

class Handler(SocketS erver.DatagramR equestHandler):
def handle(self):
contenu=time.ct ime(time.time() )
self.send(conte nu)
print "Message envoye"
time.sleep(1)


s = Broadcast(('', PORT), Handler)
s.serve_forever ()

I know I have to set the SO_BROADCAST attribute and the network mask for
the broadcast but I don't know how and where in the programm.

Are you saying you have working server client/server code that works,
but doesn't use the SocketServer ?
If so, could you post it ?

I've been trying to do the same thing, though I'd be fine with it not
using the Socketserver, but no success. Sorry.

Of course

The server

import socket
import sys
import time

GROUP = '192.168.20.255 '
HOST='192.168.2 0.73'
PORT=10000

print "Port diffusion en fonction",PORT

service = socket.socket( socket.AF_INET, socket.SOCK_DGR AM )
service.setsock opt( socket.SOL_SOCK ET, socket.SO_BROAD CAST, 1 )
service.connect ((GROUP,PORT))

while 1:
contenu=time.ct ime(time.time() )
service.send(co ntenu)
print "Message envoye"
time.sleep(1)

service.close()

And the client

import socket
import sys

host='192.168.2 0.73'
port=10000

s=socket.socket (socket.AF_INET , socket.SOCK_DGR AM)
s.setsockopt(so cket.SOL_SOCKET , socket.SO_REUSE ADDR, 1)
s.bind((host, port))

while 1:
t,server=s.recv from(65535)
print t

s.close()

I hope it will help

Thanks a bunch!

I don't have client or servers really, just peers. So I need to have
both client + server in the same process.

When I do that, the client bind fails. But when I bind to '' (empty
string) then it works. Maybe that helps you too (?)

Anyway, it works for me now, thanks a lot
