Sorry, I didn't notice that piece of code.

This should be extended to not close the socket after the first packet,
and stop reading if read to much (requires a counter). The socket should
ONLY be closed when detecting client close or timeout.

setsockopt(..., SO_RCVBUF, ...) should be added as well to shrink the
TCP receive window.

A larger timeout than 10 seconds is probably needed to handle slow
connections (modems).
