If you *really* *really* want to do this, it can be done. Run a bb localhost 'hobbitdboard host=xxxx test=conn color=red' to check the status, if it's down, you can use 'net' from samba to reboot the server (.e.g 'net rpc shutdown -r -S server -U user , with an account that has sufficient rights.
Hi Buchan, this is an interesting and inspiring idea. It would probably be unreliable in case the connection of the windows host is down. Then the net command would not work.
Most modern servers have built-in watchdogs, so that if a certain condition is met (generally frozen machine) the watchdog reboots the machine. It is a built in hardware/firmware thingie, that has its own OS, and network interface.
Then is the question of how to make such a watchdog listen to the Hobbit monitor. Most of such firmware has built in SNMP but i do not know if any of them would be able to catch a SNMP TRAP and then reboot upon that.
In this scheme, the role of the Hobbit monitor would be to monitor and send an alert to maybe a devmon or some other process that would convert that alert into a SNMP trap and send it to the watchdog.
But still, this idea is rather far fetched. :)
