# VPNMON-R3 v1.3.8 (VPNMON-R3.SH) is an all-in-one script that is optimized to maintain multiple VPN connections and is
# able to provide for the capabilities to randomly reconnect using a specified server list containing the servers of your
# choice. Special care has been taken to ensure that only the VPN connections you want to have monitored are tended to.
# This script will check the health of up to 5 VPN connections on a regular interval to see if monitored VPN conenctions
# are connected, and sends a ping to a host of your choice through each active connection. If it finds that a connection
# has been lost, it will execute a series of commands that will kill that single VPN client, and randomly picks one of
# your specified servers to reconnect to for each VPN client.
