Use OpenHAB to restart internet connect

Hi!

I’m restarting my Internet connection if it’s down. I’m not doing it on my rpi3 where openhab runs, but you could do it on the same machine where openhab runs.

A simple approach is to run a cron job every 5-15 mins or so, do a PING, and if the connection is down do a restart.

#!/bin/bash

#Your nic                                           
INTERFACE="ethX"

# These lines won't really tell if internet is up/down
# Check anyway, but not acting on it at the moment
IS_UP=`cat /sys/class/net/${INTERFACE}/operstate`
echo "$IS_UP"

# Ping twice just to be sure
/bin/ping -c 2 8.8.8.8
/bin/ping -c 2 8.8.8.8
if [ $? -ge 1 ]; then
  echo "Network down :("
  #Run some scripts here like:
 /etc/init.d/network restart
 /path/myfirewallscript
 /etc/init.d/restart some service
  exit 1
else
  echo "Network up! :)"
  exit 0
fi

You could do this in openhab with execbinding, read status and then restart or do actions within openhab.
