Konfiguration

Größe von /var/log/journal begrenzen

Über die Zeit wächst das Verzeichnis /var/log/journal deutlich an. Gerade auf kleinen vServern ist das unangenehm. Dies kann schnell auf mehrere Gigabyte anwachsen. Dies kann man in der Datei /etc/systemd/journald.conf begrenzen:

[Journal]
SystemMaxUse=32M

Einmalig kann dies auch mit folgenden Befehl aufgeräumt werden.

journalctl --vacuum-size=32M

Add User to sudoers:

usermod -aG sudo username

Automatische Updates:

Alternativ ist im Anacron bereits ein entsprechender Mechanismus implementiert: /etc/cron.daily/apt .
Nach Erstellen der Datei /etc/apt/apt.conf.d/02periodic sollte eine tägliche Systemaktualisierung starten. Hier der Inhalt der Datei 02periodic:

APT::Periodic::Enable "1";
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";
APT::Periodic::Verbose "2";
APT::Periodic::RandomSleep "11";

Armbian - WIFI

** Network Manager CLI **

use NMCLI

$ nmcli device status
DEVICE  TYPE      STATE         CONNECTION         
enp1s0  ethernet  connected     Wired connection 1 
wlp2s0  wifi      disconnected  --                 
lo      loopback  unmanaged     --  

to check radio

$ nmcli radio
WIFI-HW  WIFI     WWAN-HW  WWAN    
enabled  enabled  enabled  enabled 

Let's see what's out there... scan for AP's

$ nmcli dev wifi list
SSID                  MODE   CHAN  RATE       SIGNAL  BARS  SECURITY 
MYSSID         Infra  11    54 Mbit/s  100     ▂▄▆█  WPA2     
MYSSID         Infra  132   54 Mbit/s  100     ▂▄▆█  WPA2     
SOMEOTHERSSID  Infra  52    54 Mbit/s  49      ▂▄__  WPA2     
MYSSID         Infra  149   54 Mbit/s  45      ▂▄__  WPA2     
MYSSID         Infra  11    54 Mbit/s  42      ▂▄__  WPA2     
SOMEOTHERSSID  Infra  1     54 Mbit/s  27      ▂___  WPA2

Now, let's connect to WiFi (note, one must be root or sudo access)

Connecting to an open AP

$ nmcli device wifi connect <SSID|BSSID>

For a password protected AP, see below

$ nmcli device wifi connect <SSID|BSSID> password <password>

To set up a device as an AP - this assumes that WLAN0 is the wireless interface...

$ nmcli dev wifi hotspot ifname wlan0 <SSID> password "<password>"
