    A toy version of Wireshark (student project)2025 · github.com · ▲265

    Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

    Babyshark – Wireshark made easy (terminal UI for PCAPs)Feb 2026 · github.com · ▲151

    Hey all, I built babyshark, a terminal UI for PCAPs aimed at people who find Wireshark powerful but overwhelming. The goal is “PCAPs for humans”: Overview dashboard answers what’s happening + what to click next Domains view (hostnames first) → select a domain → jump straight to relevant flows (works even when DNS is encrypted/cached by using observed IPs from flows) Weird stuff view surfaces common failure/latency signals (retransmits/out-of-order hints, resets, handshake issues, DNS failures when visible) From there you can drill down: Flows → Packets → Explain (plain-English…

    I built a macOS tool for network engineers – it's called NetViewsFeb 2026 · netviews.app · ▲243

    Hi HN — I’m the developer of NetViews, a macOS utility I built because I wanted better visibility into what was actually happening on my wired and wireless networks. I live in the CLI, but for discovery and ongoing monitoring, I kept bouncing between tools, terminals, and mental context switches. I wanted something faster and more visual, without losing technical depth — so I built a GUI that brings my favorite diagnostics together in one place. About three months ago, I shared an early version here and got a ton of great feedback. I listened: a new name (it was PingStalker), a longer trial,…

    I built ContainerCVE – a web tool to scan public Docker images2023 · containercve.com · ▲91

    I found it odd there wasn’t a simple web tool to scan Docker Hub images for vulnerabilities. So I built one. It’s powered by the popular open-source tool Trivy.

    Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it.
