conndoc 0.2.2

Diagnose connectivity and infrastructure issues from the CLI

Conndoc

Over the years, troubleshooting the root cause of connection problems has always given me headaches. It often required using multiple different tools and manually interpreting their results.

conndoc is a simple yet extensive command-line tool that aims to make connectivity diagnosis easier. It supports checks for ping, DNS, SSL, HTTP, and TCP, and provides a handy summary view.

🗺 Roadmap

Here are some planned and upcoming features for conndoc:

• ICMP latency graph
  Show ping latencies over time as simple terminal plots.

• Traceroute support
  Trace the path packets take through the network and measure latency at each hop.

• Port scan (safe mode)
  Scan a set of common TCP ports to identify open services safely and quickly.

• Save and export results
  Export diagnostics in JSON or Markdown format for easier sharing or CI integration.

• Cross-platform packaging
  Add better support for Windows installers and Linux .deb / .rpm distributions.

• Plugin support
  Let users extend Conndoc with custom checks that integrate into the summary view.
