CDTux

CDTux is my GNU/Linux "distribution"... In fact a set of scripts to install some useful softwares for programmers on Ubuntu and Raspbian.

CDTux is a set of scripts to complete the installation of several Linux devices for my personal needs (programming oriented). It can be in some way tuned for other situations.

It configures a fresh 64 bit Ubuntu or Raspbian installation with I3, some programming languages and a few other things...

Caution: make backups, read carefully and understand the source code before running this script. You have been warned ;-)

CDTux is based on my outdated Post Install script but I made some different choices:

Ubuntu based to have richer and more up-to-date repositories
64 bits because I don't have 32 bit machine anymore
also Raspbian to play with my Raspberry Pi

Installation

Currently this script has been tested on Ubuntu 16.10 (Qemu, desktop computer and laptop) and Raspbian (Raspberry Pi 3).

Quick procedure

Install Ubuntu, Raspbian...
Execute cdtux:

sudo apt update
sudo apt install git
git clone https://github.com/CDSoft/cdtux
cd cdtux
./cdtux

Edit ~/.cdtuxrc and restart cdtux if necessary

Longer procedure

Ubuntu on a regular PC

This should be pretty easy.

If you have a CD reader on your computer, just download Ubuntu, burn the ISO and boot it.

If you want to install Ubuntu from a USB key, you can try my CDKey script to build a bootable key.

Raspbian on a Raspberry Pi

This may be a little bit trickier. I describe here a way to install and configure Raspbian without any keyboard or screen connected to the Raspberry Pi. You will need an other computer to connect to the Raspberry Pi with ssh. If you have a screen and a keyboard it should be easier.

Download and extract Raspbian.

The lite version is enough for me.

wget https://downloads.raspberrypi.org/raspbian_lite_latest
unzip *-raspbian-*-lite.zip

Flash the image on a SD card

Reference: https://www.raspberrypi.org/documentation/installation/installing-images/linux.md

Let's assume the SD card is /dev/sdc. Be very careful not to destroy one of your hard disk!

sudo dd bs=4M if=$(ls *-raspbian-*.img) of=/dev/sdc

Prepare the SD card for the first boot

SSH is not enabled by default for security reasons (https://www.raspberrypi.org/blog/a-security-update-for-raspbian-pixel/). Let's enable it (remember that the SD card is still assumed to be /dev/sdc).

mkdir /tmp/sdcard
sudo mount /dev/sdc1 /tmp/sdcard
sudo touch /tmp/sdcard/ssh
sudo umount /tmp/sdcard
sync

This will create a file named ssh on the boot partition.

First boot

Put the SD card in the Raspberry Pi SD card reader.
Plug the power supply as well as an ethernet cable.
Connect to the Raspberry Pi with ssh.

Well, you need to know the IP address of the Raspberry Pi. Your home network is probably configured to give IP addresses in a classical subnetwork (192.168.0.0/24).

You can use nmap (on your desktop or laptop) to discover the Raspberry Pi IP address:

sudo apt install nmap
nmap -sP 192.168.0.0/24
sudo nmap -sS -p 22 192.168.0.0/24

Hopefully you see something like a Raspberry Pi... Just connect and configure it with raspi-config:

ssh -X pi@192.168.0.XX
raspi-config

The default password is raspberry.

In raspi-config you can:

expand the filesystem to use the whole SD card (you will need to reboot)
change the password
enable ssh permanently (otherwise you will have to recreate the ssh file as before)
enable everything you want

Install CDTux

You are now ready to execute the cdtux script on your new Ubuntu or Raspbian installation.

Just install git and download cdtux:

sudo apt update
sudo apt install git
git clone https://github.com/CDSoft/cdtux
cd cdtux
./cdtux

You will have sometimes to provide your password to gain root privileges.

Configuration

The configuration file .cdtuxrc is a single bash script used to configure CDTux.
