- - - - How To Sanitize a Laptop
        
        The process of sanitizing a laptop involves three aspects:
        
        Installing the educational software (operating system and educational applications).
        
        Deleting the laptop's previous information.
        
        Physically cleaning the laptop's appearance.
        
        Labdoo provides two laptop sanitation manuals:
        
        Fast Restorathion Method
        
        Cloning an already existing Gnu/Linux image into the laptop directly
        
        Step by Step Installation Method
        
        The current standard process of sanitizing a laptop is as follows in the guide:
        
        The current standard process of sanitizing a laptop is as follows:
        
        If the laptop is not already tagged with a Labdoo ID number, please follow the instructions under "tagging a laptop" page. Make sure you print 3 labels and attach two of them to the laptop and one to the AC adapter following the instructions that you will find on the website.
        
        Download the Ubuntu Mate 20.04 release from this link (this is a large .iso image):
        
        http://cdimage.ubuntu.com/ubuntu-mate/releases/20.04/release/HEADER.html
        
        Burn the downloaded file into a CD. Make sure you burn the downloaded file as an ISO image. If you don't know how to do this, you can follow the instructions from any of these links depending on the type of computer you use to burn the CD:

        Insert the Lubuntu CD into the laptop you intend to sanitize and boot the laptop from the CD. Upon booting the laptop with the CD, you should see the Linux installation menu. If you don't see it, you need to enter into the bios of the laptop and change your computer's booting order to make sure that it first boots from the CD. For more information on how to configure the bios, see this page.
        
        Upon seeing the Lubuntu installation menu, start by selecting the installation language; for instance, choose “English”.
        
        Select “Install Lubuntu”.
        
        Select the language to be installed on the laptop. If you don't know the destination country, select “English”. If you know the destination country, select that country's language.
        
        In the "Wireless" screen, if you have an internet connection, you may select the network you use from the list and enter its password. Otherwise, leave it as default.
        
        The next window is just to confirm that the laptop fit into the minimum Hard Drive requirement. Hit "continue" once.

        Labtix 2
        
        improvements:
        
        Labtix 2 is based on Antix 21 and is only available in a 64-bit version. There is no longer a 32-bit version (sorry). Users who require a 32-bit version must use the earlier Labtix 1.
        
        The images provided by Labdoo on our FTP server can be processed with either Labtix 1 or Labtix 2.
        
        Labdoo team has changed the user interface as little as possible, so you don't need long training. Some changes were mandatory, e.g. Labtix 2 comes with the file manager zzzFM (Fork of SpaceFM). And 4 years of software development have passed...
        
        UEFI: The number of IT donations with UEFI will increase. Normally you turn off UEFI and Secure Boot in the BIOS and enable Legacy Boot.
        
        You need for Labtix 2:
        
        At least one 2GB USB key (recommended) or DVD to install and run Labtix 2 on. It is not possible to install Labtix 2 on a CD or a 1GB stick (too small).
        
        min. 1.5 - 2 GB RAM in the computer to be installed.l

    - - Connecting to the Labdoo FTP server
        
        The Labdoo FTP server allows users to download files and images for Labdoo devices for free. Here are some simple ways to connect to the FTP server. Pick the one that suits you best. For security reasons, Labdoo does not allow unsecured FTP protocol, only the secured SFTP protocol (no ftp, only sftp).
        
        Accessing the server through your browser
        
        Access data to connect to the FTP server
        
        Integrate into the file manager (Windows, Swish)

        Installed tools for Labtix
        
        Arandr
        
        A tool for configuring the screen layout. Very useful when your device has the internal monitor removed and an external display is connected.
        
        battery-plugin
        
        in the panel gives you information about the status of the battery when you mouse over it. The plug-in can be activated with a right mouse click and "Battery Monitor Settings", if not already done.
        
        Firefox esr
        
        is the "enterprise version" of Firefox, which is not updated as often. For example, Firefox can be used during installation to research the web. It can also display pdf files. By default it doesn't collect cookies and doesn't store data to avoid bloating Labtix with unnecessary data in persistence mode.
        
        Gparted
        
        a great tool for disk partitioning, file system repair and partition copying.
        
        Gsmartcontrol /
        DiskCheck
        
        a tool to read the S.M.A.R.T data from a hard drive to see if the hard drive is healthy. If yours is "red" in the registers, you should use a different hard drive.
        
        hard info
        
        gives you extensive information about the hardware and software of the computer.
        
        ISO snapshot
        
        a tool to create an ISO snapshot of the system. All changes to the system are saved in the snapshot. While running ISO snapshot, mark the directories NOT to be added to the snapshot, except for the "Desktop" directory which contains the .desktop files. You should move existing snapshots to a directory that you do not want to include in the snapshot. The snapshot is saved in /home/snapshot. If the snapshot is created on a non-persistent system (e.g. boots from CD-ROM), it should be saved on another device. If there is not enough disk space to save the snapshot, the save path can be e.g. to another USB stick. The snapshot can be installed to a USB stick using UNetbootin or burned to a CD-ROM or DVD-ROM using the IG Burn Tool plugin in SpaceFM.
        
        Keyboard layout handler
        
        With the Keyboard Layout Handler on the right side of the panel you can change the keyboard layout with a left mouse click. To make a permanent change, right click and use the "Keyboard Layout Handler Settings". The top keyboard layout in the list is preassigned at startup. With a left mouse click you can go through the pre-installed keyboard layouts (German, US English, French, Spanish).
        
        Blacklight Brightness
        
        Sometimes the screen is too dark and cannot be made brighter with the keyboard (function keys). Then you can change the brightness with Backlight Brightness. Works most of the time, but not always.
        
        Live USB Maker (Labtix 2)
        
        to copy Labtix to other USB sticks
        
        Avahi network scanner
        
        scans the network (please connect first) and shows e.g. the path to a server or similar.
        
        Magnify
        
        Magnifier on/off
        
        Audacious
        
        CD/DVD drive functionality test
        
        Onboard
        
        show/hide monitor keyboard.
        
        Conky
        
        A tool for displaying system information on the desktop. The output window is in the upper right corner. The configuration file is in Labtix 1: /etc/conky/conky.conf, in Labtix 2: ~/conky.rc. In Labtix 2 with even more information, such as battery status, etc.
        
        SimpleScreenRecorder
        
        Tool to record videos of the session, e.g. for training purposes.
        
        Psensor
        
        A tool to control the temperatures of CPU, GPU and others.
        
        SpaceFM (Labtix 1) /
        zzzFM (Labtix 2)
        
        is a file manager for the usual file actions and for integrating external devices. It has plugins to e.g. mount shares and burn CDs or DVDs. SpaceFM/zzzFM is highly configurable and can be modified with additional plugins. The trash can is disabled to prevent accumulation of too much data in persistence mode. If required, the trash can can be added as a plugin. It should not be removed as it is part of the desktop environment!
        
        Speaker test
        
        Speaker test right / left.
        
        Xfburn
        
        to burn Labtix from CDs/DVDs.
        
        wipefs
        
        Fast deletion of the file system (but does not replace overwriting with random numbers).
        
        UNetbootin (Labtix 1)
        
        a tool to create bootable USB sticks. Start Unetbootin, enable "Diskimage", select the ISO snapshot (should be in /home/snapshot) and select the target USB drive. The USB stick should be formatted with fat32 and it should be mounted (use SpaceFM for this). After installation on a thumbdrive, Gparted should be used to check if the boot flag is set correctly!
        
        Helpful commands (shell, terminal)
        
        acpi (-V) >> information about the powersystem like battery-state, battery-condition etc.
        
        (sudo) apt >> package manager
        
        sudo apt update >> create the needed package database
        
        sudo apt install mousepad >> installs the program "mousepad"
        
        Only usefull in the persistence mode. The device must be connected to the internet.
        
        eject -T >> ejects CDs or DVDs
        
        grep >> filters the output of commands
        
        acpi -V | grep -i battery >> shows only the lines of acpi -V wich contain the term "battery"
        
        (sudo) inxi >> system information
        
        sudo inxi -v 5 >> informations with verbosity level 5 (1-8 possible)
        
        inxi -B >> battery information
        
        sudo inxi -M >> informations about the system
        
        inxi -m >> informations about the memory
        
        Sudo is only needed if informations inxi gathers need root permissions
        
        iwconfig >> shows informations about wireless connections
        
        lsblk >> lists blockdevices like harddisks
        
        lspci >> lists all recognized pci-devices
        
        lspci | grep -i Network ( or Wireless or WLAN ) >> shows Wifi-devices
        
        lsusb >> lists all recognized USB-devices
        
        rfkill >> tool for radio devices
        
        rfkill list all >> lists the states of all radio devices
        
        rfkill unblock all >> unblocks all softblocked devices
        
        To unblock a hardblocked device:
        
        look for a hardware switch
        
        look for a keyboard function/binding
        
        look if the device is blocked in the UEFI/BIOS
        
        (sudo) shred >> tool to securely delete devices or partitions
        
        sudo shred /dev/sdX -v -f -n 2 >> overwrites sdX 2 times
        
        Shred will overwrite each single byte of the target device, so it might take a long time.
        
        BE CAREFUL !!! BE SURE TO USE THE PATH TO THE DEVICE/PARTITION YOU REALLY WANT TO CLEAN !!!
        
        sudo >> command to get root permissions
        
        In labtix no sudo-password is installed, so typing in a password is not needed
        
        wipefs >> tool to delete filesystems
        
        sudo wipefs -a -f /dev/sdX >> wipes the filesystem of sdX
        
        BE CAREFUL !!! BE SURE TO USE THE PATH TO THE DEVICE / PARTITION YOU REALLY WANT TO CLEAN !!!
        
        This is not a secure method of deleting any devices, it's the quick and dirty solution if you want to get rid of an installed system. For safe deletions use the command "shred"
        
        xkill >> tool to kill windows that are not responsible
        
        Open a terminal, type "xkill" and press "Enter". The mousepointer will be shown as a skull. Leftclick with the skull inside the window you want to close. Xkill will only close windows. In some cases processes started by the killed window might still run in the background.
        
        Do not click on the Desktop, it is a window too !!!
        
        xrandr >> tool to manipulate the graphical-(x-)server
        
        xrandr --output eDP-1 --scale 0.5x0.5 >> reduces the height and width resolution of output eDP-1 by the factor 0.5 . Very useful if the screen has a very high resolution.
        
        To get the name of the actual output:
        
        xrandr | grep primary

      - Pre-Requirements:
        
        A laptop with wireless LAN and gigabit ethernet port
        
        A gigabit switch
        
        Network cables to connect the clients
        
        Wireless internet access where you are NOT using the IPv4 network address 192.168.20.0/24
        
        Installbox Setup
        
        Download the customized ISO image: GET-LATEST-VERSION-FROM-WEB.iso
        
        Either burn the image to a CD or write it to a USB key using dd if=debian-jessie-installbox.iso of=/dev/sdb
        
        (replace sdb with the device node of your USB stick, if necessary).
        
        Boot the laptop using the CD or the USB stick.
        
        Please do not connect the ethernet cable yet.
        
        Select the option "Install" during boot.
        
        You will be asked to select the keyboard layout, select the one that fits best for you.
        
        During network set-up please select the wireless interface. There should be two interfaces on the list:
        
        Note: If you do not see those two interfaces here, please abort the installation process. It means that your device is not supported.
        
        When you have selected wlan0, the installer will search for wireless networks available. Select your network.
        
        Type in your Wireless password in the next step. Please note that it is displayed in a clear text.
        
        Relax, the rest of the installation should work fully automated.
        
        After a while the device reboots, so you can now connect an ethernet cable from the laptop's installation box to the gigabit switch.
        
        You should now be able to connect any client to the switch and select ethernet boot.
        
        On Lenovo, you can press F12 and choose the network interface as a boot device.
        
        On the install box, an NFS export has been created on /exports.
        
        This will be available to all clients on the LAN and should contain the Clonezilla images.
        
        PXE Boot Options
        
        When you boot a client, the boot menu will show the following options:
        
        Clonezilla Autorestore x86
        
        Clonezilla Autorestore x86_64
        
        Preseed x86
        
        Preseed x86_64
        
        Clonezilla Autosave x86
        
        Clonezilla Autosave x86_64
        
        Clonezilla Live
        
        SystemRescueCD
        
        Boot and Nuke
        
        Workflow
        
        After you have set up the install box a typical workflow would be the following:
        
        Create a master image
