To begin you need to install Debian 8.1.
Critical step in the installation process.
Non-free firmware
When the installation process ask for “Some of you hardware needs non-free firmware – the missing firmware files are rtl_nic/rtl8168g-2.fw”, you need to download from Debian Packaged web site package named firmware-realtek (see linkografia), uncompress it to an USB stick (using 7zip for example): after that you can insert USB key in your Acer and continue with installation process.
Disk Partition
My choice: Guided – use entire – all file in one partition
Software Selection
My choice: SSH server and standard system utilities
Root SSH Access
You need to permit root user to get via SSH in order to facilitate the configuration steps.
> sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config > service sshd restart
