VPNCheck

VPNCheck is designed to initiate an OpenVPN connection and maintain that connection.

Well I would love to rely on the built-in OpenVPN method to maintain a connection I've found it to be unreliable; This is my solution to that problem.

Installation

git clone https://github.com/FroggMaster/VPNCheck.git

Usage

1. Define your OVPN connection file in the CONNECTSCRIPT variable.
2. Configure a Crontab schedule to run VPNCheck
3. Wait for Crontab to initialize VPNCheck

Crontab Schedule (Every 1 Minute)

*/1 * * * * /bin/bash $HOME/VPNCheck/vpncheck.sh

Debug Crontab Schedule (Every 1 Minute + STDERR and STDOUT)

*/1 * * * * cd $HOME/VPNCheck ; $HOME/VPNCheck/vpncheck.sh >> $HOME/VPNCheck/cronlog.log 2>&1
