update-kali

This is a tool to set up Kali Linux quickly with additional packages and maintain them over time. You can also use this script with other debian-based distros like Ubuntu.

What is this?

I need to keep a group of Kali linux boxes up to date, and I like them to be setup in a similar format. This script installs the tools I'm likely to use, creates directories, etc. It's set up for my personal use, but with a little modification you can use it too:

Fork the repo so that you can commit your changes to config.py, and so the script updates from your account fork in future
Update config.py with your preferences
Go through /scripts/, delete the ones you don't want, and add any of your own that you want to run.
Make sure you have the following installed: python3, python-apt and git.

Config

The default config can be found in config.py. You should updated it to match what you want, otherwise you'll use my preferences and calamity will ensue. This script will:

Perform a general package update
Install and remove specified apt packages
Install specified python modules, golang tools and ruby gems
Set up and remove specified directories
Sync specified git repos to ~/, or a directory you nominate (private repos, such as dotfiles, notes, etc)
Sync specified git repos to /opt, or a directory you nominate (public repos, such as wordlists)
Run all the scripts in /scripts

Note: This script will change the ownership of your tools directory, which is /opt by default, to your user so that you aren't building with sudo privileges. Change the tools directory if you don't want that to happen.

Supporting Scripts

Updating Go modules

The Go modules you install will most likely keep on getting worked on, but you'll only get the benefit of those once you update and recompile the associated repository. This takes a long time, so I've added a separate command update-go-modules that iterates through updating them.

Updating Python modules

You can update all python pip modules across the system using update-python-modules. Be aware that this may introduce breaking changes for your Python scripts, which is why venv is your friend. Expect to get errors when you run this, since some packages are supplied by the system.

Updating Ruby Gems

As above, you can update all ruby gems with update-ruby-gems. This basically runs gem outdated; gem update, but it seemed consistent to put it into a script.

Shell Scripts

Lastly, this tool will run each of the .sh or .py files in the scripts directory. If you add a script to this directory, make sure they can be run multiple times without causing a problem. You can use the following script that installs Google Chrome as a template:

#!/bin/bash
set -Eeuo pipefail
trap "echo -e \"\033[1;31m[!] \e[0m Script error occured.\"" ERR

GREEN="\033[1;32m"
ENDCOLOR="\033[0m"

# === Exit without proceeding if run in WSL ===
if [ -f /mnt/c/Windows/System32/wsl.exe ]; then
    exit 0
fi

# Check if Chrome is installed
if [ $(sudo dpkg-query -W -f='${Status}' google-chrome-stable 2>/dev/null | grep -c "ok installed") -eq 0 ]
then
    echo -ne $GREEN"[+] "$ENDCOLOR; echo "Installing Google Chrome"
    cd ~
    wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
    sudo dpkg -i google-chrome-stable_current_amd64.deb
    rm -rf google-chrome-stable_current_amd64.deb
fi
