Small (another word for naive in this case, it's simple and serves my needs) Rack application providing the information an OpenVPN server collects in it's status file especially including a list of currently connected clients (common name, remote address, traffic, ...).
- caching (parses file on each request, page does auto-refresh every minute as OpenVPN updates the status file these often by default)
- management interface support
- possibly more...
Install the gem:
gem install openvpn-status-web
Create a configuration file in YAML format somewhere:
# listen address and port host: "0.0.0.0" port: "8080" # optional: drop priviliges in case you want to but you should give this user at least read access on the log files user: "nobody" group: "nogroup" # logfile is optional, logs to STDOUT else logfile: "openvpn-status-web.log" # hash with each VPNs display name for humans as key and further config as value vpns: My Small VPN: # the status file path and status file format version are required version: 1 status_file: "/var/log/openvpn-status.log" My Other VPN: version: 3 status_file: "/var/log/other-openvpn-status.log"
Your OpenVPN configuration should contain something like this:
# ...snip... status /var/log/openvpn-status.log status-version 1 # ...snip...
For more information about OpenVPN status file and version, see their man page. openvpn-status-web is able to parse all versions from 1 to 3.
If the information exposed is important to you serve it via the VPN or use a webserver as a proxy to handle SSL and/or HTTP authentication.
There is a Dockerfile that can be used to build a Docker image for running openvpn-status-web.
The Debian 6 init script assumes that openvpn-status-web is installed into the system ruby (no RVM support) and the config.yaml is at
/opt/openvpn-status-web/config.yaml. Modify to your needs.
