In Linux, you can enable timestamps on any socket executing: int val = 1; setsockopt(sock, SOL_SOCKET, SO_TIMESTAMP, &val, sizeof(val)); PD: Current release of tcpdump doesn't mmap the reception ring and timestamps packets at user space with gettimeofday. It isn't the best performing alternative, but it's portable. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
