1. Objective: 

Install ALARM - Arch Linux ARM on the raspberry 2, change SSH settings, change network (static ip) Setup: Lenovo Yoga 13 (2012) Arch Hardware Requirements: Raspberry Pi 2, MicroSD Card

2. Realisation:

• Read and work through this guide¹. Command not found error when formatting –> check dosfstools package status
• SSH to your RasPi2. The ip can usually be found in your router entries.         $ ssh root@<RasPi2_ip\>
• Change root password         $ passwd
• Change SSH port Why? –> Yes, if someone does a portscan on your system a changed port is of little help ². Still, many attackers seem to routinely look for open ssh systems on port 22. $ nano /etc/ssh/sshd_config then change #Port 22 to Port  
• Log out and try to login with $ ssh root@<raspi2_ip> -p  <yourportnumber>
• Update the system and install necessary software $ pacman -Syu $ pacman -Sy screen wget base-devel unzip
• Create additional user $ useradd -m -G wheel, power -s /bin/bash <username> -G (groups) wheel for using sudo, power to reboot the device / -m (user directory) creates user directory at /home/ / -s (shell) usually bash Change new user password `$ passwd ` Add user group wheel to sudoers file You have to do this as root `$ nano /etc/sudoers ALL=(ALL) ALL)` Uncomment user group wheel Reboot and login as
• Install yaourt from source ³ Check that base-devel is installed $ sudo pacman -Sy base-devel First install package-query (yaourt dependency) $ wget https://aur.archlinux.org/packages/pa/package-query/package-query.tar.gz $ tar -xvzf package-query.tar.gz $ cd package-query $ makepkg -si Then install yaourt  Move to upper folder  $ cd ../  $ wget https://aur.archlinux.org/packages/ya/yaourt/yaourt.tar.gz $ tar -xvzf yaourt.tar.gz $ cd yaourt $ makepkg -si
