Using the plotters

Emulation is nice to save energy and prevent redundancy, you don't need a machine for every project because you can install that virtual machine on several systems. It is really convenient for testing purposes
-------------------------------
Get a virtual machine
-------------------------------

• Install virtualbox
• Create a New virtual machine
  • Give it a name and choose a folder to install the virtual machine in
  • ISO image = the Linux distro you want (look for it on distrowatch)
    • Debian: get it from debian.org > download > amd64.iso (arm64 for newest Macs)
    • Type is Linux
    • Subtype corresponds to the one chosen (Debian)
    • Version is the version of Debian
  • Set username and password
  • Choose the settings for system capacity and memory usage
  • Finish

-------------------------------
Get a graphical interface
-------------------------------

su
//enter password
apt install kde-plasma-desktop

-------------------------------
Print with plotters
-------------------------------

• Install python

su
//enter password
apt install python3.12-venv //or python3.11-venv

• Run venv

python3 -m venv
source bin/activate

• Install chiplotle

pip install chiplotle3

• Run chiplotle

chiplotle3

• Config file

• Print!

-------------------------------
Print cowsay fortune telling
-------------------------------

sudo apt install cowsay
sudo apt install fortune
fortune | cowsay

To check the animal/character options of cowsay:

cowsay -l

Print cowsay fortune prompts into a txt file so you can save them, choose from them and copy/paste them elswhere (such as inkscape to print them with the plotters <3)

fortune | cowsay -f duck >> cowsay-fortunes.txt

Server

When installing Linux, in the "software selection (gui)" window, pick:

• web server
• ssh server
• standard system utilities

After installation complete, remove usb stick and wait to be prompted the username and password

Installation: mastodon instance

SSH to Debby

ssh xpub@145.24.152.64 //the hub IP is 10.0.0.19
enter password

Jump user

get your jump.pub ssh key from your local .ssh folder
paste the key into /.ssh/authorized_keys on Debby
add also your own personal .pub ssh key (not linked to cerealbox) in the same file

Edit the ssh config file

In your local .ssh folder, open the config file and duplicate the last cerealbox entry, then update information for Debby as follows:

Host debby
Hostname 10.0.0.19
User xpub
ProxyJump xvm_jump
Identityfile ~/.ssh/id_rsa [this last part should be the name of your personal ssh key file, mine is id_rsa but yours might be different]

for the local address:

Host debby_local
Hostname 145.24.152.64
User xpub
Identityfile ~/.ssh/id_rsa

Packages installed

• tmux

Launch tmux:

one writes tmux new

others write tmux attach

Mastodon glitch-soc installation

• Installation guide
  

In order to use the installation commands from the guide, we need to log into the root with su and then run the commands

/!\ After enabling corepack, the documentation doesn't say it but you should install yarn by just writing yarn in the terminal

adduser doesn't work? here's how to resolve it:
Unhide the adduser command using the following command:

sudo update-alternatives --install /bin/adduser adduser /usr/sbin/adduser 20

then run again

adduser --disabled-password mastodon

• Subdomain
