# per-device Provisioning
|
|
For production, the devices need to be provisoned uniquely
|
|
- provision with rpi-sb-provisioner - tested with 2.0.5, 2.0.4 did not work
|
|
- access the webinterface with ssh -L 3142:127.0.0.1:3142 pi@192.168.178.52
|
|
- http://localhost:3142
|
|
- after initial provisioning using ssh:
|
|
- install vpn with a unique configuration under /etc/wireguard/wg0.conf
|
|
- wg-quick up wg0
|
|
- enable wg0 service
|
|
- set the hostname
|
|
- if custom device without ui:
|
|
- set channel name etc. in bumble-auracast/src/auracast/.env
|
|
- execute the update service scripts
|
|
- start the application (script if custom device, server and frontend if ui version)
|
|
- set mac add of secondary eth port in /etc/systemd/network/10-eth1-mac.link
|
|
- activate overlayfs (?) -probably not because we need persistent storage for stream states
|
|
|
|
## Secure-boot CM4: unlock secure USB mass-storage
|
|
bash gen-secure-msd-sig.sh
|
|
bash rpi-boot-secure.sh
