It distinguishes itself by providing detailed workflows for restricting high-risk features and applying advanced security configurations to protect the operating system. The documentation covers several k

Free, open-source terminal SSH manager and SSH config editor in Rust for macOS and Linux that keeps ~/.ssh/config in sync with 16 cloud providers, monitors live SSH tunnels and manages Docker and Podman containers fleet-wide. Plus scp, Vault SSH certs and an MCP server for AI agents.

Real-time monitoring of Linux process network traffic, including the client IP, port, and transfer speed for each connection.

This project is a curated knowledge base and technical reference for shell scripting, focused on performing common system tasks using only built-in shell features. It serves as a guide for implementing logic and automation without relying on external binaries or dependencies, ensuring scripts remain portable across standard Unix-like environments. The repository distinguishes itself by emphasizing native shell functions and syntax to minimize process forking and improve execution performance. It provides idiomatic patterns for complex string transformations, pattern matching, and data flow ma

Below is a system metrics recorder and replayer for Linux. It captures live hardware utilization, cgroup hierarchy data, and pressure stall information, saving everything into a single replayable snapshot file. This decouples collection from analysis, allowing you to inspect system state offline as if viewing it in real time. The tool continuously streams metrics to disk during recording, supporting interruption and later replay without data loss. It exports the same internal data in multiple formats—OpenMetrics for direct Prometheus and Grafana ingestion, as well as JSON and CSV for script-b

b4n is a terminal user interface (TUI) for the Kubernetes API, created mainly for learning the Rust programming language. It is heavily based on the k9s project and built using the kube-rs and ratatui crates.
