sys-inspector 0.90.4

eBPF-based System Inspector and Forensic Tool (Multi-Agent/Web)

sys-inspector - eBPF-based System Inspector and Audit Tool

Sys-Inspector is an advanced observability and forensic tool powered by eBPF (Extended Berkeley Packet Filter).

Unlike traditional tools that poll /proc periodically, Sys-Inspector hooks directly into the Linux Kernel to capture events (process execution, file I/O, network connections) in real-time.

Features (v0.90.00)

• Fleet View Dashboard: Monitor multiple infrastructure nodes from a single centralized web interface.
• Forensic Time Machine: Pause live execution and travel back in time to inspect historical snapshots stored in SQLite.
• Kernel-Level Visibility: Uses eBPF kprobes/tracepoints for zero-blindspot monitoring.
• Deep Forensics:
  • Real-time MD5 Hashes: Calculates hashes of executed binaries instantly.
  • Context Awareness: Detects SSH origin IPs, Sudo users, and Tmux sessions.
  • Recursive Alert Bubbling: Child process anomalies (e.g., Unsafe Libs, Net Errors) propagate warnings up to the parent process in the tree view.
• Topology & Infrastructure:
  • Storage Topology: Hierarchical view of Disks -> Partitions -> LVM -> Mount Points with HCTL info.
  • Network Topology: Auto-detection of Gateway, DNS servers, and Interfaces.
• Enterprise Reporting:
  • Generates self-contained, interactive HTML Dashboards.
  • Custom Logo Support: Embeds your organization's logo automatically.
  • Visual Badges: Instant identification of [SSH], [SUDO], [UNSAFE], [NET ERR].

Requirements

• Linux Kernel 4.15+ (5.x+ recommended for BTF support).
• Root privileges (sudo).
• Python 3.6+.
• BCC Tools (python3-bcc).
• iproute2 (for tc command, required only for Chaos Maker).
• Additional Python libs: flask, cryptography, pyyaml.

Installation (PyPI)

Works on any Linux distribution with Python 3.6+.

    pip install sys-inspector

Installation (RPM / openSUSE)

You can install Sys-Inspector directly via zypper using the openSUSE Build Service repository.

1. Add the Repository:

    zypper addrepo https://download.opensuse.org/repositories/home:mariosergiosl:sys-inspector/15.6/home:mariosergiosl:sys-inspector.repo

1. Refresh and Accept GPG Key: During the refresh, you will be asked to trust the repository GPG key.

Fingerprint: 7CF0 5795 053C F397 8E00 948E 9F8D 1AC9 E2BE EABC

    zypper refresh
    # Type 'a' to trust always when prompted.

1. Install the Package:

    zypper install sys-inspector

1. Run: Once installed, the command is available globally:

    sys-inspector

Usage

Sys-Inspector is orchestrated via the main.py entry point (or globally as sys-inspector). It supports multiple execution modes.

1. Local Live Mode (Recommended)

Starts the background collector daemon and the Fleet Web Dashboard simultaneously.

    sudo sys-inspector --mode local-live
    # Access the dashboard at http://localhost:8080

2. Snapshot Mode (Static Report)

Captures activity for a specific duration and generates a standalone HTML report.

    sudo sys-inspector --mode snapshot --interval 20
    # Output Example: report/sys-inspector_hostname_20260316_100000.html

3. Custom Logo

To include your company logo in the report header, simply place a PNG file at the following path:

    /etc/sys-inspector/logo.png

The application will automatically detect, resize (max-height: 40px), encode it to Base64, and embed it in the HTML.

Chaos Engineering (Testing Tool)

Included in scripts/chaos_maker.sh is a stress testing tool designed to validate the inspector's detection capabilities.

⚠️ WARNING: DO NOT RUN ON PRODUCTION SYSTEMS. This script uses tc (Traffic Control) to purposefully degrade network quality (packet loss/latency) and consumes CPU/Disk resources.

Capabilities

• Network Degradation: Injects 100ms latency and 20% packet loss to trigger [NET ERR] alerts in the report.
• Process Anomalies: Hides processes in /dev/shm to trigger [WARN] alerts.
• Unsafe Library Loading: Forces loading of dynamic libraries from /tmp via a Python script to trigger [UNSAFE] alerts.
• Disk Stress: Generates high I/O throughput to test IO accounting.

How to Run

    sudo ./scripts/chaos_maker.sh

To Stop: Press Ctrl+C. The script traps the signal and automatically cleans up the network rules (tc qdisc del) and temporary files.
