Simple web UI to manage OpenVPN users, their certificates & routes in Linux. While backend is written in Go, frontend is based on Vue.js.
Originally created in [Flant](https://flant.com/) for internal needs & used for years, then updated to be more modern and [publicly released](https://blog.flant.com/introducing-ovpn-admin-web-interface-for-openvpn/) in March'21. Your contributions are welcome!
***DISCLAIMER!** This project was created for experienced users (system administrators) and private (e.g., protected by network policies) environments only. Thus, it is not implemented with security in mind (e.g., it doesn't strictly check all parameters passed by users, etc.). It also relies heavily on files and fails if required files aren't available.*

## Notes
* This tool uses external calls for `bash`, `coreutils` and `easy-rsa`, thus **Linux systems only are supported** at the moment.
* To enable additional password authentication, provide `--auth` and `--auth.db="/etc/easyrsa/pki/users.db`" flags and install [openvpn-user](https://github.com/pashcovich/openvpn-user/releases/latest). This tool should be available in your `$PATH` and its binary should be executable (`+x`).
* If you use `--ccd` and `--ccd.path="/etc/openvpn/ccd"` and plan to use static address setup for users, do not forget to provide `--ovpn.network="172.16.100.0/24"` with valid openvpn-server network.
* If you want to pass all the traffic generated by the user, you need to edit `ovpn-admin/templates/client.conf.tpl` and uncomment `redirect-gateway def1`.
* Tested with openvpn-server versions 2.4 and 2.5 and with tls-auth mode only.
* Not tested with Easy-RSA version > 3.0.8.
* Status of user connections update every 28 seconds.
* Master-replica synchronization and additional password authentication do not work with `--storage.backend=kubernetes.secrets` - **WIP**

## Authors
## Further information
ovpn-admin was originally created in [Flant](https://github.com/flant/) and used internally for years.
In March 2021, it [went public](https://medium.com/flant-com/introducing-ovpn-admin-a-web-interface-to-manage-openvpn-users-d81705ad8f23) and was still developed in Flant.
Namely, [@vitaliy-sn](https://github.com/vitaliy-sn) created its first version in Python, and [@pashcovich](https://github.com/pashcovich) rewrote it in Go.
In November 2024, this project was moved to [Palark](https://github.com/palark/), which is currently responsible for its maintenance and development.
Please feel free to use [issues](https://github.com/flant/ovpn-admin/issues) and [discussions](https://github.com/flant/ovpn-admin/discussions) to get help from maintainers & community.
