I'm pretty sure read() will read until it hits EOF. With a socket,
you won't get an end of file until the socket is closed. So, your
program is working as it should :). You probably will want to send
the length of the string from the client before you send the string
itself. This way your server knows how long the string should be.
You might also want to take a look at the xdr module. It has methods
which can bundle up things like strings so they work better over a
