The following I should remember for Raspberry PI.
1.) Keyboard Layout is EN by default – so type raspberrz to get raspberry as default Password
2.) if you close up all ports – keep at least one or two backdoors open (21 SSH for putty.exe 5900 VNC)
3.) install tightvncserver (for more comfort) (sudo apt-get install tightvncserver and then start with tightvncserver)
4.) command line tools to keep in mind: pcmanfm (file Explorer), leafpad (editor – I hate VI since it exists – even before my birth)
5.) sudo su –> get to the root
6.) set Passwort to a secure one: sudo passwd or passwd is enough, don’t set root’s password (it is more secure that you cannot reach root directly through logon) (Google says)
7.) “Kill” Desktop: sudo openbox –exit
8.) sudo reboot on error 🙂
9.) sudo raspi-config

Important packages

1.) sudo apt-get install tightvncserver
2.) sudo apt-get install xmlstarlet

Stupid Picture Viewer issues – recompile

sudo apt-get remove pqiv
sudo apt-get install git libgtk2.0-dev
git clone -b 0.12
cd pqiv
leafpad pqiv.c im Verzeichnis /home/pi/pqiv öffnen. “gchar option”; durch “gint option”; ersetzen.
sudo make all install
