|
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
|
|
|
|
## Requirements
|
|
- Make
|
|
- Go 1.19 or later
|
|
- NetworkManager
|
|
- systemd
|
|
- Linux operating system
|
|

```bash
|
|
make build
|
|
make run
|

## API
|
|
|
|
The full API specification can be found in [api/rcond.yaml](api/rcond.yaml).
|
|
|
|
### Authentication
|
|
|
|
All endpoints except `/health` require authentication via an API token passed in the `X-API-Token` header. The token is configured via the `RCOND_API_TOKEN` environment variable when starting the daemon.

|
| GET | `/health` | Health check endpoint |

|
| POST | `/network/ap` | Create and activate a WiFi access point |
|
|
| PUT | `/network/interface/{interface}` | Activate a connection |
|
|
| DELETE | `/network/interface/{interface}` | Deactivate a connection |

|
| DELETE | `/network/connection/{uuid}` | Remove a connection |

## Examples
|
|
|
|
### Setup an Access Point
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
set -euo pipefail
|
|
|
|
# Example script to create and activate a WiFi access point
|
|
# Requires:
|
|
# - RCOND_ADDR (default: http://0.0.0.0:8080)
|
|
# - RCOND_API_TOKEN (your API token)
|
|
|
|
API_URL="${RCOND_ADDR:-http://0.0.0.0:8080}"
|
|
API_TOKEN="${RCOND_API_TOKEN:-your_api_token}"
|
|
INTERFACE="wlan0"
|
|
SSID="MyAccessPoint"
|
|
PASSWORD="StrongPassword"
|
|
|
|
echo "Creating access point '$SSID' on interface '$INTERFACE'..."
|
|
ap_response=$(curl -sSf -X POST "$API_URL/network/ap" \
|
|
-H "Content-Type: application/json" \
|
|
-H "X-API-Token: $API_TOKEN" \
|
|
-d '{
|
|
"interface": "'"$INTERFACE"'",
|
|
"ssid": "'"$SSID"'",
|
|
"password": "'"$PASSWORD"'"
|
|
}')
|
|
|
|
# Extract the UUID from the JSON response
|
|
AP_UUID=$(echo "$ap_response" | jq -r '.uuid')
|
|
|
|
echo "Activating connection with UUID '$AP_UUID' on interface '$INTERFACE'..."
|
|
curl -sSf -X PUT "$API_URL/network/interface/$INTERFACE" \
|
|
-H "Content-Type: application/json" \
|
|
-H "X-API-Token: $API_TOKEN" \
|
|
-d '{
|
|
"uuid": "'"$AP_UUID"'"
|
|
}'
|
|
|
|
echo "Access point '$SSID' is now up and running on $INTERFACE."
