Nadzoring (from Russian "надзор" — supervision/oversight + the English "-ing" suffix) is a free and open-source command-line tool and Python library designed for in-depth network diagnostics, service availability monitoring, and website block detection. It empowers you to investigate connectivity issues, analyze network configurations, and audit security postures through a comprehensive suite of tools. From DNS diagnostics (including reverse lookups, poisoning detection, and delegation tracing) to ARP spoofing monitoring, SSL/TLS certificate analysis, HTTP security header auditing, email security validation (SPF/DKIM/DMARC), and subdomain discovery — Nadzoring brings together a wide range of capabilities in a single, consistent interface.

Built from the ground up with AI-friendliness in mind, Nadzoring is fully type-annotated, enforces a strict zero-warnings linter policy, and is architected according to SOLID principles with a strong emphasis on modularity and the Single Responsibility Principle (SRP). This architectural clarity ensures that the codebase remains maintainable, testable, and easy to extend. The project's high-quality typing and well-structured domain logic make it equally suitable for use as a reliable Python library in your own applications, as well as a powerful standalone CLI tool.

Getting Started

Prerequisites

• Python 3.12+
• pip

Optional system utilities:

Utility	Required by
traceroute / tracepath	network-base traceroute (Linux)
whois	network-base whois
ip / route	network-base params, network-base route
net-tools	network-base params on some Linux distros (sudo apt install net-tools)
ss	network-base connections (Linux)
dig / nslookup	security check-email (DNS TXT lookups; dnspython used when available)

Note: The Python package netifaces (used by network-base params) is distributed as source code and requires compilation on Linux. If you encounter errors during installation (e.g., gcc: command not found), install the required build tools first: sudo apt update && sudo apt install build-essential python3-dev (Debian/Ubuntu) or the equivalent for your distribution. On other platforms (Windows, macOS) pre‑compiled wheels are usually available.

Installation

pip install nadzoring

Verify:

nadzoring --help

Development version:

pip install git+https://github.com/alexeev-prog/nadzoring.git

Running with Docker

For Linux users, Docker provides the easiest and most stable way to run Nadzoring without system dependency issues. The container comes with all necessary network capabilities pre-configured.

📘 Detailed Docker Guide: See Docker.md for complete Docker setup instructions, including native Windows alternatives, development tips, and troubleshooting.

Quick start with Docker:

# Clone the repository
git clone https://github.com/alexeev-prog/nadzoring.git
cd nadzoring

# Build the Docker image
docker build -t nadzoring:latest .

# Create a convenient alias (add to ~/.bashrc or ~/.zshrc)
alias nadzoring='docker run --rm -it \
  --network host \
  --cap-add=NET_ADMIN \
  --cap-add=NET_RAW \
  nadzoring:latest'

# Now use Nadzoring normally
nadzoring --help
nadzoring dns resolve google.com
nadzoring network-base port-scan 192.168.1.0/24
nadzoring arp detect-spoofing

Benefits of using Docker:

• Isolated environment — No Python version conflicts or dependency issues
• Easy updates — Just rebuild the image with git pull && docker build
• No system modifications — Leaves your host system untouched
• Consistent behavior — Works the same across different Linux distributions
• Network capabilities — Pre-configured with NET_ADMIN and NET_RAW for full functionality

Platform recommendation:

Platform	Recommended Method	Best For
Linux	Docker (with alias)	Servers, CI/CD
Linux	Native (pipx)	Most users, development
Windows	Native (pipx)	Windows-users

Note for Windows users: Docker on Windows has limitations with raw sockets and local network access. Native installation via pipx is strongly recommended for Windows. See Docker.md for Windows-specific guidance.

Basic Usage

Nadzoring uses a hierarchical command structure: nadzoring <group> <command> [OPTIONS]. The four main groups are dns, network-base, security, and arp.

Global Options

These options work with every command:

Option	Short	Description	Default
--verbose		Enable debug output with execution timing	False
--quiet		Suppress non-error output	False
--no-color		Disable colored output	False
--output	-o	Output format: table, json, csv, html, html_table, yaml	table
--save		Save results to file	None
--timeout		Lifetime timeout for the entire operation (seconds)	30.0
--connect-timeout		Connection timeout (seconds). Falls back to --timeout	5.0
--read-timeout		Read timeout (seconds). Falls back to --timeout	10.0
--proxy		SOCKS5 proxy URL (e.g., socks5://127.0.0.1:1080). All HTTP/HTTPS traffic uses this proxy.	None

Timeout resolution order:

1. Explicit --connect-timeout / --read-timeout
2. Generic --timeout (applies to both phases when phase-specific not set)
3. Module-level defaults (shown above)

Shell Completions

Nadzoring provides tab-completion support for bash, zsh, fish, and PowerShell. Enable it for your preferred shell using the commands below.

Bash

Add to ~/.bashrc (or ~/.bash_profile on macOS):

echo 'eval "$(nadzoring completion bash)"' >> ~/.bashrc
source ~/.bashrc

Alternative — save to a file and source it:

nadzoring completion bash > ~/.nadzoring-complete.bash
echo 'source ~/.nadzoring-complete.bash' >> ~/.bashrc

Zsh

Add to ~/.zshrc:

echo 'eval "$(nadzoring completion zsh)"' >> ~/.zshrc
source ~/.zshrc

Or save to a file in your fpath:

nadzoring completion zsh > "${fpath[1]}/_nadzoring"

Fish

Save directly to Fish completions directory:

nadzoring completion fish > ~/.config/fish/completions/nadzoring.fish

Or source it temporarily:

nadzoring completion fish | source

PowerShell

Add to your PowerShell profile ($PROFILE):

nadzoring completion powershell >> $PROFILE

To reload the profile immediately:

. $PROFILE

Or use it in the current session only:

nadzoring completion powershell | Invoke-Expression

Testing Completions

After installation, type nadzoring followed by TAB to see available commands:

nadzoring [TAB]
# Should show: arp  completion  dns  network-base  security

Type a command followed by space and TAB to see options:

nadzoring dns [TAB]
# Should show: resolve  reverse  check  trace  compare  health  benchmark  poisoning  monitor

Manual Activation (without saving to profile)

If you don't want to modify your shell profile, you can activate completions manually:

# Bash / Zsh
source <(nadzoring completion bash)

# Fish
nadzoring completion fish | source

# PowerShell
nadzoring completion powershell | Invoke-Expression

Troubleshooting Completions

Completions not working? Check these common issues:

1. Shell not reloaded — restart your terminal or run source ~/.bashrc (bash) / source ~/.zshrc (zsh)
2. Wrong shell — ensure you're using the correct completion command for your shell
3. PATH issue — verify nadzoring is in your PATH: which nadzoring
4. Completion not registered — run the activation command directly to see if there are any errors

Debugging bash completions:

# Enable debug output
set -x
nadzoring [TAB]
set +x

Check if completion is registered:

# Bash
complete -p | grep nadzoring
# Should output: complete -o nosort -F _nadzoring_completion nadzoring

# Zsh
echo $fpath | grep nadzoring

Show installation hints:

nadzoring completion hints bash      # For bash
nadzoring completion hints zsh       # For zsh
nadzoring completion hints fish      # For fish
nadzoring completion hints powershell  # For PowerShell
