title: Reconnect after connection closet with openvpn
body: <p>I'm working through a vpn which is under an unstable connection, so I developed the following script that allows a reconnection if any intermittency in connection with ovpn happens.</p>
  
  <pre><code>#!/bin/bash
  export PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin
  
  function getStatus () {
      ifconfig | grep $1 &amp;&amp; return 1
      return 0
  }
  
  while [[ 1 ]]; do
      getStatus tun0
      if [[ $? == 0 ]]; then
          echo "openvpn is not connected!"
          echo "Reconnecting!"
                  #Replace your_sudo_password to your real user sudo password.
          echo my_sudo_password | sudo -S openvpn --config /home/user/openvpn/my_host_vpn.ovpn
          sleep 6
      fi
      sleep 6
  done
  </code></pre>
  
  <p>The problem is that if I interrupt the connection, nothing happens. Simply displays:</p>

  <p>My question is: how I can stop safely vpn connection so that the script can attempt reconnection. Openvpn simply does not release the tun0 interface, so the script believes the connection is still active, What should I do?</p>
