openvpn_check

## This script checks to see if the tun0 device exists within the transmission jail. If not, it restarts OpenVPN. I have this run as a CRON job every 20 minutes.
currentDate=$(date "+%b %d %H:%M:%S")

if iocage exec transmission ifconfig | grep -c "tun0" > /dev/null
then
    echo "$currentDate VPN Check Successful. OpenVPN is still running." >> /var/log/messages
else
    echo "$currentDate VPN Connection is down. Restarting OpenVPN." >> /var/log/messages
    iocage exec transmission service openvpn restart
