Hallo Zusammen,
wir haben an einer Schule extrem viele Notebooks, die wir „irgendwie“ gerne über WLAN-Syncen wollen. Eine Variante dazu, die ich heute „zusammengebastelt“ habe sieht etwa so aus:
- Samba-Freigabe meines Images
root@server:~# cat /etc/samba/smb.conf.admin
# …
[mate-20-image]
path = /srv/linbo/images/mate-20
public = yes
writable = no
comment = freigabe fuer onlinesync
printable = no
guest ok = yes
root@server:~#
-
im Linuxclient wird screen + rtorrent benötigt:
apt install rtorrent screen -
folgendes Skript starte ich mittels Crontab beim Start des Gerätes
linuxadmin@master-mate:/mnt/cache$ cat /etc/linuxmuster-linuxclient7/offlinesync.sh
#!/bin/bash
#1. Mount /cache + Mount samba-share
sudo mount //server/mate-20-image /mnt/mate-20-image -o guest
sudo mount /dev/sda2 /mnt/cache
#2 start torrent
screen -S torrent -d -m bash -c 'rtorrent'
~

- unter /root/.rtorrent.rc
root@master-mate:~# cat .rtorrent.rc

jetzt sollten folgende Dinge passieren:
- beim starten des Geräts werden /cache und samba → image gemountet.
- wenn dort eine neue .torrent-datei vorhanden ist, wird das .qcow2 in /cache geladen
- anschließend kann man ein Gerät mit neuem Abbild syncen, obwohl es nicht mit Kabelnetzwerk verbunden ist
Was ich nicht so gut finde (aber naja, eigentlich wollte ich heute Brücktage machen):
- das ganze läuft als root, besser wäre wenn man für diese funktion einen Nutzer anlegt
- unter NVME lässt sich das Medium vermutlich nicht mounten. (dirty workaround: oben einfach gleiches aufführen)
Findet das jemand besonders doof das so zu machen? Gibt es Einwände/Verbesserungsvorschläge?
