openvpn-monitor

Summary

openvpn-monitor is a simple python program to generate html that displays the status of an OpenVPN server, including all current connections. It uses the OpenVPN management console. It typically runs on the same host as the OpenVPN server, however it does not necessarily need to.

Source

The current source code is available on github:

Configuration

Configure OpenVPN

Add the following line to your OpenVPN server configuration to run the management console on 127.0.0.1 port 5555:

management 127.0.0.1 5555

Refer to the OpenVPN documentation for further information on how to secure access to the management interface.

Configure openvpn-monitor

Copy the example configuration file openvpn-monitor.conf.example to the same directory as openvpn-monitor.py.

cp openvpn-monitor.conf.example openvpn-monitor.conf

In this file you can set site name, add a logo, set the default map location (latitude and longitude). If not set, the default location is New York, USA.

Once configured, navigate to http://myipaddress/openvpn-monitor/

Note the trailing slash, the images may not appear without it.

Debugging

openvpn-monitor can be run from the command line in order to test if the html generates correctly:

cd /var/www/html/openvpn-monitor
python openvpn-monitor.py

Further debugging can be enabled by specifying the --debug flag:

cd /var/www/html/openvpn-monitor
python openvpn-monitor.py -d
