Managed outlet and remote reboot of equipment: how to implement?

Question

Iron

Good afternoon,
I'm sure that many who are somehow connected with system administration were looking for a solution to remotely reboot "hung" equipment. Who found what solutions, preferably something serial?
PS The advice should not start: Tfu-you, you take an old router, a soldering iron.

Answer 1

there is a spread from ready-made controlled pieces of iron like

to voltage control controllers with a choke in the outlet.
shop.nag.ru/catalog/00007.Avtomatizatsiya-i-monito...
and, of course, control of a 220v outlet by enabling the active PoE port on the router to be turned off through the throttle from the car.

Answer 2

IMHO the closest is NetPing.
There are also various Ethernet controlled PDUs from various manufacturers.

Answer 3

Dig towards WatchDog "watchdog".
There are a lot of implementations: from those built into the motherboard, to devices that inform you about a problem with a piece of hardware and let it reboot.
