Network diagnostics that don't suck.

    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…

    I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip. (Available at…

    Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution (https://github.com/cjjeakle/network-monitor), feel free to clone and try it out! I know there are a lot more mature monitoring…

    Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

    Hi HN! After several months of work, I'm excited to share ProKZee, a free and open-source network security tool built with Go and React using Wails framework. ProKZee allows developers, security researchers, and penetration testers to intercept, inspect, and modify HTTP/S traffic — similar to tools like Burp Suite, OWASP ZAP, and Caido — but with a fast native UI, modern UX, and some unique features. https://github.com/al-sultani/prokzee

    Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted more: fast, reliable scans using ARP tables and ICMP. As a Wi-Fi engineer, I couldn’t stop there. I kept adding ways to…
