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:

https://github.com/furlongm/openvpn-monitor

Quick Install on Debian 8 using apache

These steps have been tested on Debian 8 but should be general enough for Ubuntu, CentOS, etc.

Install dependencies

apt-get install libapache2-mod-python python-geoip python-ipaddr python-humanize apache2 git
cd /var/www/html
git clone https://github.com/furlongm/openvpn-monitor.git
a2enmod python cgid

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 Apache

Add the following to /etc/apache2/sites-enabled/000-default.conf

    <Directory "/var/www/html/openvpn-monitor">
        Options +ExecCGI
        AddHandler cgi-script .py
        DirectoryIndex openvpn-monitor.py
    </Directory>

and restart apache:

/etc/init.d/apache2 restart

Download the GeoLite City Database

cd /usr/share/GeoIP/
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz
mv GeoLiteCity.dat GeoIPCity.dat

Configure OpenVPN-Monitor

The example configuration file /var/www/html/openvpn.cfg should give some indication of how to set site name, add a logo, etc. You can also set a default location (latitude and longitude) for the embedded maps. If not set, the default location is Melbourne, Australia.

Edit /var/www/html/openvpn.cfg to match your site. You should now be able to navigate to http://myipaddress/openvpn-monitor

Debugging

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

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