socket.send() may not send all the data - it returns a count telling you what it actually did. Use socket.sendall() or put your call to send() in a loop. > and receive it like this : > > def recevoir(conn): > data='' > while 1: > tmpdata = conn.recv(8192) > data += tmpdata > if '#####' in data: > print 'END OF DATA' > break > print len(data)/1024, ' KB received' > return passed, int(data[-15:-5])/1024 socket.recv() will return an empty string when there is no more data - I would look for that instead of your marker, it is more general. Instead of if '#####' in data: you can say if data == '': or just if not data: > > But I don't receive as much data that I sent ... does someone know why ? > If I want to send the same data back to the client, do I have to destroy > and recreate the socket ? If this doesn't fix it, maybe an example of the lost data would help.
