Dear All, How can I maintain constant/minimum socket receive buffer. I have used setsockopt() with SO_RCVBUF value for 256bytes But according to tcpdump window size is changing after connection is estabilished. Can It be possible to set socket receive buffer value less than sysctl_tcp_rmem's minimum value. Do I have to disable tcp_window_scaling Thankx Regards Tharindu -- Tharindu Rukshan Bamunuarachchi asmlinkage void __init start_kernel(void) - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
