Hello.
I want to share with you a simple program to automatically hard-reset your machines if they got stuck.
I'm using Raspberry Pi with 5V relay but you can use any other mini-computer as well (Beaglebone Black, Orange Pi & etc.). I will add better instructions with pictures soon.
Logic is: Ping machines every 33 minutes. If there is no response - Hard-reset.
Just download the binary file and edit the config.json
Soon I will add web interface for statistics
Additional information and basic instructions are available on github
