CLI commands

This tool started as a curiosity about low-level networking. I built a capture loop in Python, parsed packets into structured data, and surfaced the results through a lightweight HTML viewer.

Shell scripts bundle common operations so I can launch captures with the right permissions, filter protocols, and archive sessions quickly.

Challenge

Existing packet analyzers felt heavy for quick experiments and were overkill for simple demos.

Approach

Implemented a minimal capture pipeline in Python with an HTML view that highlights the important headers first and collapses detail on demand.

Outcome

Helps me demo networking concepts in workshops without relying on bulky tooling and keeps sample traces organized for future reference.

Highlights
  • Interface-level capture with protocol-aware parsing
  • Readable HTML summaries for sharing findings
  • Command-line helpers to automate the capture workflow

Core Capabilities

Capture and parse packets at interface level
Filter and inspect headers (source, destination, ports, protocol)
Generate human-readable HTML summaries of sessions
Automation scripts for environment setup and teardown
