I'm making some headway trying to keep this a self-contained project with no dependencies outside of ip and tc. At this point, it looks like we'll make the main script a daemon along with a cron job which checks if the daemon has stopped and restarts it automatically. We chose a daemon so we could keep the array of samples in memory and minimize disk IO but we will write enough to disk to maintain state in the event of a reboot - John -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
