Exploring BlackArch on an Old Machine

After spending a long time on macOS, I started missing the level of control and customization that Linux offers.

Yes, macOS has a terminal and a solid Unix base, but it doesn’t quite match the freedom you get with a full Linux environment. I had access to VPS instances for scripting and experimentation, but that’s not the same as having a machine you can fully tweak and break without consequences. So I decided to revive an old laptop I had lying around.

The Setup

The machine wasn’t in perfect condition, but it still had decent specs:

Intel i7 (4th Gen)
8 GB RAM
500 GB HDD

More than enough to experiment with.

I installed Arch Linux and updated everything. One thing I had forgotten was how smooth updates are in Arch. A single command and the entire system stays up to date.

That’s when I started thinking about how to actually use this setup.

Why BlackArch?

The idea was simple. If I have a dedicated Linux machine, why not turn it into a security testing environment?

That’s where BlackArch comes in.

BlackArch is essentially a massive repository of penetration testing tools built on top of Arch Linux. Instead of installing a separate distro, you can convert your existing Arch setup into a full security toolkit.

Setting Up BlackArch

There are two main ways to install BlackArch tools on Arch Linux.

Method 1: Using the Strap Script

# Add BlackArch repository
curl -s http://blackarch.org/strap.sh | sudo sh

# List all available tools
sudo pacman -Sgg | grep blackarch | cut -d' ' -f2 | sort -u

# Install all tools
sudo pacman -S blackarch

# Install specific category
sudo pacman -S blackarch-<category>

# List categories
sudo pacman -Sg | grep blackarch

# Add BlackArch repository
curl -s http://blackarch.org/strap.sh | sudo sh

# List all available tools
sudo pacman -Sgg | grep blackarch | cut -d' ' -f2 | sort -u

# Install all tools
sudo pacman -S blackarch

# Install specific category
sudo pacman -S blackarch-<category>

# List categories
sudo pacman -Sg | grep blackarch

Method 2: Using Blackman

Install the helper tool:

sudo pacman -S blackman

sudo pacman -S blackman

Then use it to manage installations:

# Install a specific tool
sudo blackman -i <package>

# Install a category
sudo blackman -g <group>

# Install all tools
sudo blackman -a

# List categories
blackman -l

# List tools in a category
blackman -p <category>

# Install a specific tool
sudo blackman -i <package>

# Install a category
sudo blackman -g <group>

# Install all tools
sudo blackman -a

# List categories
blackman -l

# List tools in a category
blackman -p <category>

Desktop and Customization

To keep things lightweight and distraction-free, I switched to a minimal desktop environment using Openbox with a dark theme.

This setup made the system feel fast and clean, even on older hardware.

Why This Setup Works

What stood out the most was how effortless package management is in Arch. Compared to macOS, where you often deal with manual installs and dependency issues, Arch’s package manager just works.

Everything is:

Centralized
Scriptable
Easy to maintain

And that makes a huge difference when working with hundreds of tools.

Final Thoughts

This setup turned an old, partially broken laptop into a fully functional penetration testing lab.

It also reminded me why Linux, especially Arch-based systems, remains unmatched when it comes to customization and control.

If you enjoy tinkering, experimenting, or diving into security, combining Arch Linux with BlackArch is a powerful and flexible way to build your own environment.
