A bit off topic, but I keep looking for an answer to this question and coming up with nothing... so I thought I would go to the gurus. :-) Can anyone recommend a good package for pinging other devices and sending an email/alert when they go down? I'm aware of all kinds of more complex things with GUIs and a zillion other bells and whistles we aren't looking for, but we just want a simple tool (could be daemon or something run from cron) that runs every 1 - 5 minutes and alerts us when stuff disappears. Would need some basic logic like only sending one email/alert when something goes down (vs sending an email every 1-5 minutes until it comes back up). :-) We need to avoid a requirement for an X-windows GUI, but a web-GUI would probably be fine (a GUI-less command-line thing would probably be best). TIA, KC
