RE: [newbie] Automatic Reboot Scheduling
I would imagine it is easy enough to do, set-up a cron job and get it to do a reboot -r. Never tried so you will be a guinea pig. As everybody else has said I can see no benefit in doing this on a daily basis.

Anyone have any idea of how I should go about doing this? Slightly OT: you can easyly set up an old computer with an old modem to dial in to (or which has a permanent net connection) and let it powercycle the main machine when it has crashed. See http://www.telenovela-world.com/~spade/linux/howto/Coffee.html for details :-) -Frans Another way is to pick up a watchdog timer card, and let it reboot the machine if it locks up. There are several that are supported out of the box by the kernel, and it shouldn't be too hard to make others work. There is also a software version, but it isn't as dependable. It can not recover from a lockup inside a driver that has interrupts turned off. The hardware versions do not suffer from this limitation. These watchdog timer cards are expensive though I think. They may be able to reboot the machine more subtly than a power cycle would, but I guess this depends on the kind of lock up and the capabilities of the card. You could also use an old (= 386) computer to monitor the main machine by checking if it continually flips a bit on an unused parallel or serial port (with the main machine configured to do so) and after a timeout period power cycling the main machine. At least it would be cheap (hardware wise) ;-) On the other hand, with the normal uptime for a Linux server measured in months or years, it usually isn't needed... It has been years since I locked up, or crashed a Linux system that wasn't caused by hardware failing, loss of power, or by my exparmenting with something as root that I knew was risky.

I will be a long way away from the machine in question, and its a new setup. I have seen it freeze once in the last two weeks and I cant have it doing the same when Im away from it. (Possibly hardware but at this stage Im uncertain). Hence the need to ensure it keeps working by giving it a reboot every 24 hours. I just cant afford to have it go down, even though it probably wont but know murphys law it probably will. Lee Want to buy your Pack or Services from MandrakeSoft?
