Das Schließsystem läuft auf einem RaspberryPi mit der Erweiterungsplatine "PiFaceDigitalIO".
|
||||
|
||||
|
||||
## Konfiguration
|
||||
|
||||
Falls `/etc/foodoord.conf` nicht vorhanden ist:
|
||||
|
||||
* `mv /etc/foodoord.conf_example /etc/foodoord.conf`
|
||||
|
||||
1. Trage dort die API-Config für den Türstatus ein.
|
||||
2. Falls nicht schon beim Paketinstall geschehen, mit `systemctl enable --now foodoord@oben` oder `systemctl enable --now foodoord@unten` enablen und starten.
|
||||
|
||||
|
||||
|
||||
## Software
|
||||
|
||||
### Dateiliste
|
||||
|
||||
Der Daemon besteht aus folgenden Dateien.
|
||||
|
||||
* foodoor
|
||||
* foodoord
|
||||
* foodoord.conf
|
||||
* foodoor-update-keydb
|
||||
* foodoord@.service
|
||||
|
||||
Zusätzlich sollte für das git-repo eine Config angelegt werden:
|
||||
|
||||
/root/.ssh/config
|
||||
```
|
||||
Host git.chaospott.de
|
||||
User git
|
||||
Port 2222
|
||||
IdentityFile ~/.ssh/id_chaospott
|
||||
```
|
||||
|
||||
Das IdentityFile ist der Deploy-SSH-Key, der im [Repo](https://git.chaospott.de/Chaospott/foodoor-keys) hinterlegt ist.
|
||||
|
||||
|
||||
## Schüssel
|
||||
|
||||
### Schlüsselupdate
|
||||
|
||||
`foodoor-update-keydb`
|
||||
Aktualisiert die Schlüssel auf der Tür und baut die *Authorized_Keys* für die User *open* und *close*. Keys die nicht dem OpenSSH-Format mit 4096 bit entsprechen, werden ignoriert. Wenn das Script von Hand aufgerufen wird, werden die betroffenen Keys angezeigt. Über einen Cronjob werden die Keys alle **5 Min aktualisiert**.
|
||||
|
||||
### Schlüsselformate
|
||||
|
||||
Der foodoord akzeptiert nur Pub-Keys im *OpenSSH2-Format*. Keys lassen sich unter anderem mit OpenSSH oder PuTTygen erzeugen.
|
||||
|
||||
### OpenSSH
|
||||
|
||||
#### Keys generieren
|
||||
|
||||
* Mit `ssh-keygen -b 4096` lassen sich Keys generieren.
|
||||
* `ssh-add $Pfad_zum_Key` fügt den Key dem ssh-Agent hinzu. Die Option `ssh-add -l` zeigt geladene Keys an.
|
||||
* `ssh-kegen -l -f $Pfad_zum_Key` gibt den Fingerprint und andere Informationen zurück.
|
||||
|
||||
|
||||
#### Keys konvertieren (PuTTy > OpenSSH):
|
||||
|
||||
* `ssh-keygen -i $Pfad_zum_Key > $Pfad_neuer_Pfad.pub<` liest ssh2-kompatible Keys (RFC 4716) ein und speichert diese im OpenSSH-Format.
|
||||
|
||||
|
||||
### PuTTy
|
||||
|
||||
Da die Tür nur Keys im OpenSSH-Format verträgt, dürfen auch mit Putty nur OpenSSH-Keys genutzt werden.
|
||||
|
||||
#### Keys generieren (OpenSSH-Format mit PuttyGen):
|
||||
|
||||
1. PuTTYgen öffnen
|
||||
2. Unten "Number of Bits in a generated Key:" 4096 eintippen
|
||||
3. "Generate" klicken um Key zu generieren
|
||||
4. Nach dem Generieren oben im Menu "Conversions" > "Export OpenSSH-Key"
|
||||
5. Speichern
|
||||
|
||||
Es ist zu beachten, dass Putty den PrivateKey im Putty-Format benötigt! Das heißt, falls der generierte Key vor dem Export nicht gespeichert wurde, muss der private Key noch konvertiert werden, siehe nächster Punkt!
|
||||
|
||||
|
||||
#### Keys konvertieren (OpenSSH > PuTTy):
|
||||
|
||||
1. PuTTYgen öffnen
|
||||
2. "Load" drücken
|
||||
3. OpenSSH-Key auswählen
|
||||
4. "Save Private-Key" drücken
|
||||
5. Speichern
|
||||
|
||||
|
||||
## Hardware
|
||||
|
||||
### Input:
|
||||
|
||||
* ssh-login
|
||||
* Klingel
|
||||
* Statustaster
|
||||
|
||||
### Output:
|
||||
|
||||
* Status LEDs
|
||||
* Summer
|
||||
* Keymatic
