T3X

The cuddly waffle toolset for T3 Raspberry Pi image creation & maintenance.

This tool augments the Alaska T3 program and the T3 Alliance Raspberry Pi (RPi) ecosystem by providing the t3x tool to assist in creating a standardized T3 Raspberry Pi platform. The project has a few goals:

• Improve our ability to configure and harden the operating system and services used in T3 PIs.
• Ensure the ability to update and synchronize the recommended tools and configurations for T3 projects and RPi systems.
• Provide a platform for T3 RPi hackers to share and engage with neat tools and solutions to problems that evolve what we can do together.
• An interface to engaging with fun and silly things along with the serious stuff.

[!note] Safe, Secure, Accessible & Fun: The core mission of this project is to provide an interface that allows T3 learners to fortify the security and configuration of their devices, protecting them from potential cyber threats. It's not just about providing technology; it's about delivering safe and secure technology. Doing this should also be fun and adaptable to the evolving needs of the T3 community and their projects.

Installation

Fully manual clone steps:

git clone git@github.com:uaf-t3/t3x
cd t3x
# Review the scripts starting with bootstrap.sh
./scripts/bootstrap.sh

Trust the T3X CHEESE lab team? Recommended easy method:

curl https://raw.githubusercontent.com/uaf-t3/t3x/main/scripts/bootstrap.sh | bash -e

Changes/Impacts of installing T3X

• .bashrc will be setup to include .bash.d/*.sh scripts
• .bash.d/00-t3x.sh will setup $HOME/t3x/bin in user PATH
• .bash.d/00-local.sh will ensure $HOME/.local/bin is in user PATH
• .bash.d/(other).sh other scripts added for quality of life or when a user choosed to include/add a new feature that augments.

Beyond that the impacts of T3X will depend on what tools from it you run.

t3x Usage

The t3x command offers an interface to a collection of scripts and tools.

Scripts

t3x bootstrap or $HOME/t3x/scripts/bootstrap.sh

• Gets t3x installed & into a good state by the following steps:
• Verify functional access to the Internet
• Ensures basic tools needed for bootstrap (git) are available
• Fetches the latest version of the t3x main branch.
• Setup $HOME/.bash.d folder.
• Use .bash.d/00-t3x.sh to ensure $HOME/t3x/bin is in $PATH

t3x update

• Attempt to update t3x using git

t3x sanity

• Tries to ensure all the tool dependancies for t3x are done
• This is done as part of bootstrap but can be run again later to ensure any new dependancies are available.
