If the 'if' condition not executing then it must be because the
received data isn't "/quit", so what is it? Print it out, or, even
better, print out repr(data), which will show you any spaces or "\n" in
it.

sock.recv(RECV_BUFFER) will receive up to RECV_BUFFER bytes, so if the
sender is sending other stuff after the "/quit" and RECV_BUFFER > 5,
then you might be receiving some of that later stuff too.
