# rcond
A simple daemon and REST API to manage:
- network connections through NetworkManager's D-Bus interface
- system hostname through the hostname1 service
- authorized SSH keys through the user's authorized_keys file
## Build and Run
```bash
make build
make run
```
## API
The full API specification can be found in [api/rcond.yaml](api/rcond.yaml).
