Tezos-Node: If Connection To Private Node is Lost, Trust then Connect

privconnect.sh

#!/bin/bash

# Usage ./privconnect.sh 300 1.1.1.1
# checks twice, 300 seconds in between, if the node the script is being run on
# is connected to 1.1.1.1:9732. If it isn't trust then connect.
# Run it from cron, make sure the cron interval is greater than the sleep period
# between connection checks in this script. 2x or 3x the sleep period is good.
