Is there a way to make shure that all packets has been sent before issuing a Shutdown and/or Close on a (TCP) Socket?
The problem is that "the other end" interprets a reset-flag (RST) on an IP- packet as an indication of an error. Instead the finish-flag (FIN) must be set, in order to close the connection non-errornously. That can be achieved by using socket.shutdown(SHUT_RDWR) followed by socket.close(). BUT if all data has not been sent, sometimes shutdown(SHUT_RDWR) followed by close(), sets RST, and the other end thinks that something went wrong (the other end is some unknown TCP/IP printer) and goes to an error-state. ------- Tomas -- http://mail.python.org/mailman/listinfo/python-list
