To enable old Version 1 SMB protocol version add vers=1.0
Die user Option hat eine doppelte Bedeutung. Steht sie allein, werden keine root Rechte zum mounten benötigt. Wird ein username bei user= angegeben, so bezieht sich dieser auf den Server. Die Option users mit einem s am Ende erlaubt, dass keine root Rechte benötigt werden und dass alle user die Partition umounten kann.
uid=
gid=
Für Multiusersysteme ist die Option noperm für cifs mounts hilfreich.

echo -e "Subject: Backup PS2NAS\n\n" > tmp; cat `date "+%y%m%d"_copyprotocol` >> tmp; cat tmp | msmtp mail@me
Bei Fehler:
msmtp: TLS certificate verification failed: the certificate fingerprint does not match
msmtp: could not send mail (account default from /root/.msmtprc)
Das tun:
msmtp --serverinfo --tls --tls-certcheck=off --host=smtp.1und1.de --port 587

Uses who want to run MPI jobs will need to have write permissions for the following devices:
The simplest way to do this is to add the users to the rdma group.

OpenMPI will need to pin memory. Edit /etc/security/limits.conf and add the line:

speed is the speed of the port: 1 for 2.5 Gbyte/sec, 2 for 5.0 Gbyte/sec, and 4 for 10.0 Gbyte/sec.
ibportstate 14 1 speed 7
operation "enable" hilft um den link speed zu aktivieren

debian/devuan vs BSD
Mein persönlicher Eindruck, wo einige Unterschiede sind.
* Bei D/D werden Log Datein regelmäßig gelöscht. Monatlich? Nach einem Reboot? Bei BSD ist die Grundeinstellung, dass auch nach Jahren Log Datein vorhanden sind. Gut, um längerfristige Veränderungen am System festzustellen. Von z.B. Hardware (Bus Errors), Malware
Festplatten testen
Zum testen von Festplatten nutze ich den destructiven Test von dem Programm badblocks. Die Festplatte wird dabei komplett vier mal überschrieben. Die SMART Werte der Festplatte speichere ich vor dem Testen mit badblocks ab und hinterher ein Vergleich zu machen.
Da das Programm badblocks im Falle von fehlerhaften Blöcken die Blocknummer auf die Konsole ausgibt und man bei vielen Ausgaben die Fortschrittsanzeige nicht mehr sieht, kann diese Ausgabe mit der -o Option in eine Datei umgeleitet werden.
badblocks -swv -o badblocks.txt /dev/sdb
Test with random data 131072*4096b = 512MB
