–check-for-update-interval=604800 unterbindet die nervigen Updatehinweise.
Kurz testen, wer Lust dazu hat.

Mit / ohne Cursor, je nach dem, was benötigt wird, mit Cursor können Login Daten hinterlegt werden, wenn nötig.
Strg-Alt-Backspace stoppt die ganze Aktion wieder.
Tragen wir das Ganze noch für den Autostart in die .bash_profile ein.
Btw. wieder mit / ohne Cursor…

Tipps…
Zum Anzeigen der Verzeichnisse mit SSH auf den Volumes.
|

cd /[Volume] find . -type d -name "@eaDir" |
Und zum Löschen…
|
1 |
find . -type d -name "@eaDir" -print0 | xargs -0 rm -rf |
Hier mal eine Möglichkeit die nervigen (Erinnerungs) Mails vom Kalender abzustellen.
|
1 2 |
sudo -i rm /usr/syno/etc/preference/[username]/google_authenticator |
Jetzt sollte der Login ohne 2FA wieder möglich sein.
Ganz kurz und knapp…

Auf Grund des täglichen Wahnsinns im Beruf, werden jetzt auch einige Excel Beiträge folgen. Man(n) kann sich ja nicht alles merken.
Die Excel Regel an sich kurz beschrieben. $D1 das Feld wo der Wert steht, „Test“ der Wert an sich, geht auch mit anderen Formeln, z.B. heute().

=$D1="Test" =$D1=heute() |
In der heutigen Zeit bereiten Server die über eine IPv4 und IPv6 Adresse erreichbar sind, manchmal Probleme. Deshalb kann es nützlich sein, wenn man die IPv6 Adresse eines Server deaktiviert.
Bei Ubuntu 18.04 Bionic geht das wie folgt.
Man legt die Datei /etc/sysctl.d/01-disable-ipv6.conf mit dem folgenden Inhalt an und startet den Server hinterher neu.
|
1 |
nano /etc/sysctl.d/01-disable-ipv6.conf |
|

net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 |
