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

Owncloud-Client ist nicht in den Repos:

wget -nv https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_11/Release.key -O - | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/owncloud.gpg > /dev/null


  echo 'deb https://download.owncloud.com/desktop/ownCloud/stable/latest/linux/Debian_11/ /' | sudo tee -a /etc/apt/sources.list.d/owncloud.list


   apt-get update -y

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>


Cool, eh?


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>"
