# This script will reboot an obelisk miner over an ssh connection from a
# Linux VM, docker container or Linux host.
# If you have a lot of different passwords set, you can also use the -f option
# for sshpass to supply a password file or even better: Use keyfiles instead!

#!/bin/bash
#
# This script will reboot an obelisk miner over an ssh connection.
# Adapted from upgradeOB1.sh for this single task.
#
# NOTE: You will need the environment variable OB1_PASSWORD set to the password
# of the remote machine, and you will need the environment variable
# OB1_NETADDRESS to the network address of the remote machine.
#
# CRON:
# To reboot on a schedule, create a cronjob such as:
# 0 1 * * * export OB1_PASSWORD="obelisk" OB1_NETADDRESS="192.168.1.254"; /usr/local/bin/rebootOB1.sh > /dev/null 2>&1 
# The above example will reboot the obelisk miner every night at 1 AM.
#
# MULTIPLE MINERS:
# To reboot multiple hosts with this script either create different CRON entries OR use a hostfile in a bash script loop
# like outlined in the reboot-multiple-miners.sh script
