The problem is: linux doesn't uses KEEPALIVE by default.
If you believe the problem is with the Linux kernel, perhaps you should take up your case on a more appropriate mailing list? Python's socket module is a fairly low-level module, as it's just a thin wrapper around the corresponding operating system calls. Anyone using it has to be prepared to deal with a certain amount of exposed operating system details. If you want to use TCP KEEPALIVE on Linux, then just call: my_socket_object.setsockopt(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) Most non-trivial applications use select() or poll() to avoid blocking calls and do their own timeout-checking at the application layer, so they don't need KEEPALIVE. -- Daniel Stutzbach, Ph.D. President, Stutzbach Enterprises, LLC <http://stutzbachenterprises.com>
