When a new WireGuard connection is created and configured via the NetworkManager GUI (can also be called via `nm-connection-editor`), it is the Connection Editor Plugin which is executed.

When the connection is activated, it is the service plugin that is being called.

A very basic testing suite is provided in the form of the Python script `examples/dbus/dbus.py`, which looks up the Plugin via name on D-BUS and sends it a Connect() instruction. More or less the same thing (and more) can however be achieved by just using NetworkManager after installing the package, so there should not be a need for this - except for the fact that the script is easily modifiable.

Over the course of the project, I created some files that are not required for the project itself, but rather for its development.
|

Here is a brief overview over some of them:
|
||||
* `includes2strings.py`: Searches the input for `-I` flags (useful for extracting the include dirs from a Makefile)
|
||||
* `examples/dbus/dbus.py`: A small script that tests the availability of the Plugin and its responsiveness to D-BUS messages

#### D-Bus Allowance
|

D-BUS does not allow just anybody to own any D-BUS service name they like. Thus, it may be necessary to tell D-BUS that it is not forbidden to use the name `org.freedesktop.NetworkManager.wireguard`.

D-Bus does not allow just anybody to own any D-Bus service name they like. Thus, it may be necessary to tell D-Bus that it is not forbidden to use the name `org.freedesktop.NetworkManager.wireguard`.

This can be achieved by placing an appropriate file (like `nm-wireguard-service.conf`) inside the directory `/etc/dbus-1/system.d` or similar.

NetworkManager has to be told where the plugins live in order to be able to call them. This is done via `service.name` files, which usually reside in `/etc/NetworkManager/VPN` or `/usr/lib/NetworkManager/VPN` (e.g. `/usr/lib/NetworkManager/VPN/nm-wireguard-service.name`).

### Service (the Plugin itself)
|
||||
|
||||
The service is responsible for setting up a VPN connection with the supplied parameters. For this, it has to implement a [D-BUS interface](https://developer.gnome.org/NetworkManager/stable/gdbus-org.freedesktop.NetworkManager.VPN.Plugin.html) and listen to incoming requests, which will be sent by NetworkManager in due time (i.e. when the user tells NM to set up the appropriate VPN connection).

|

If the binary service is not running at the time when NM wants to set up the connection, it will try to start the binary ad hoc.

In principle, this piece of software can be written in any language, but in order to make the implementation sane, there should at least exist convenient D-BUS bindings for the language. Further, there are parts of the code already implemented in C, which might make it more convenient to just stick to that.
