TCP message

[factorion]

I am currently trying to send strings across a tcp connection between two computers. My problem is that python receives ALL the strings together instead of receiving each string as I send it. I want to be able to receive each string separately and parse it before receiving the next one. Will I have to split the string on the receiving end or is there something simple that I'm missing?

[server]

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM,
                         socket.IPPROTO_TCP)
sock.connect((comp[0], 7777))
sock.send(string1)
sock.send(string2)
...
sock.shutdown(socket.SHUT_RDWR)
sock.close()

[client]

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 
                       socket.IPPROTO_TCP)
sock.settimeout(10)
sock.bind(('', 7777))
sock.listen(1)
conn, addr = sock.accept()
while(1):
   message = conn.recv(1024)
   if not message:
      break
   <parse message>
sock.shutdown(socket.SHUT_RDWR)
sock.close()

sock = socket.socket(socket.AF_INET,

When you specify a byte size to receive it will try to receive as much as is available at that time. Unless you know the exact size of your messages, you'll need to rely on client-side parsing.

A good way to achieve this is to append some kind of end tag to your messages (which is what I've done in the past) for example, "MSG_RSP"
