[gelöst] anacron und systemd-inhibit

Profbunny · Beitrag von **Profbunny** » 25.04.2017 20:31:48

Hallo,
ich betreibe einen anacron user beschrieben wie hier http://akeil.net/posts/user-controlled-anacron.html
Dieser führt mein daily backup script aus:
obnam:

Code: Alles auswählen

#!/bin/bash
 set -x
 export DISPLAY=:0.0
 notify-send  "Starting obnam backup..." --icon=/usr/share/icons/Adwaita/256x256/devices/media-floppy.png
 echo whoami
 whoami
 
 yad --text='obnam backup' --notification --image=/usr/share/icons/Adwaita/256x256/devices/media-floppy.png&
 
 sleep 5
 
 if ! /bin/systemd-inhibit --what=shutdown:sleep --who=obnam --why="Backup in progress" --mode=block obnam backup; then
      notify-send "Unable to finish obnam backup."
         killall yad
         exit 1
     else
         killall yad
         notify-send "Finished obnam backup."
 fi
 
 exit 0

Dieses Script für sich allein gestartet, macht genau was es soll. Will sagen, backup läuft und dabei kann ich den Rechner nicht ausschalten.
Wenn nun allerdings anacron das Script startet, bricht es mit einer Fehlermeldung ab, die ich nicht verstehe. Zuerst dachte ich an rechte Probleme, passiert ja recht häufig. Also habe ich mal ein whoami eingebaut und siehe da, er startet das Script mit meinem Benutzer.
Hier ist die Ausgabe der mail con anacron.

+ export DISPLAY=:0.0
+ DISPLAY=:0.0
+ echo ' obnam daily backup'
obnam daily backup
+ notify-send 'Starting obnam backup...' --icon=/usr/share/icons/Adwaita/256x256/devices/media-floppy.png
+ echo whoami
whoami
+ whoami
mdomann
+ /bin/systemd-inhibit --what=shutdown:sleep --who=obnam '--why=Backup in progress' --mode=block obnam backup
+ yad '--text=obnam backup' --notification --image=/usr/share/icons/Adwaita/256x256/devices/media-floppy.png
Failed to inhibit: Access denied
+ notify-send 'Unable to finish obnam backup.'
+ exit 1
run-parts: /home/mdomann/.anacron/cron.daily/obnam exited with return code 1

Wenn das Script mit meinem Benutzer läuft, wieso kann ich dann auf einmal nicht mehr mit systemd-inhibit arbeiten?
Jemand ne Idee?
Micha

Wenn es klappt, führst Du das Skript in einem Terminalfenster auf Deinem Desktop oder von der virtuellen Konsole aus (Strg-Alt-F1 -F6)?
Resp. wenn der cron/anacron-Job läuft, erscheint eine Nachricht auf dem Desktop (nicht nur des mdomann)?
Geht der Job / das Skript nicht implizit davon aus, daß zur Laufzeit auch mdomann am Desktop angemeldet ist?

Generell 'yad' als '/usr/bin/yad' eintragen?

Das Script läuft vom Terminal aus. Wenn der Rechner läuft, bin ich auch angemeldet.

Also das Problem scheint tiefer zu liegen.

Scheint so, dass keine Creditails über den Socket gehen können, also der Zugriff zu Dbus geblockt wird und es deswegen nicht funktioniert. Bin mir nicht klar ob das ein Bug ist oder so gewollt.
Habe auch noch keine Idee, ob ich das irgendwie steuern kann.

Dieses Script für sich allein gestartet, macht genau was es soll.

Als root gestartet?
Als welcher Benutzer läuft der cron/anacron-Job?

Hier ein wenig herumprobiert,
der normale Benutzer kann kein systemd-inhibit auf ein 'sleep 10' setzen,
der root aber schon.

Die Antwort ist recht einfach, aber war nervig zu finden. Wenn das Script von einem Terminal gestartet wird, setzt Policykit die Entsprechenden Zugriffsrechte.
Wenn der Cronjob läuft fehlen dies Rechte und dadurch blockt er die Anfrage an systemd-inhibit.

Die Lösung war, ein eigene pkla für polkit anzulegen:

Code: Alles auswählen

Wie hast Du das zusammenkonstruiert?

Ein 'sed' auf Deine Action:

vermutlich könnte ich einige der Actions entfernen, aber bin froh das das erstmal funktioniert
