Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I have a TCP connection that is sending bulk data from a Linux 2.4.17 machine to a client. At some point, one of the packets from the Linux machine is lost, so the client asks for a retransmit by acking the last received correct packet. Then the Linux machine just keeps filling the clients open window, ignoring that and subsequent retransmit requests, never retransmitting any data. Around the time of the packet loss happened, the counter TCPRenoRecoveryFail increased by one, but I'm not sufficiently into the TCP code to figure out why that happens and if that is the reason why Linux stop retransmitting anything.. any ideas ? The client is a Windows machine, but the packets it sends does not seem broken in any way. /BW - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
