    WireHub is a side project I've been working on, on and off, for close to a year now. It's made with django and minimal javascript. It's a hosted WireGuard config generator/manager, that you can invite others to join your networks and manage their own configs/devices. It's still very much a beta, maybe an mvp, but I just wanted to get some early from the community. Thanks!

    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…

    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'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.

    This program can be used to tunnel TCP connections through a file. People have used it for interesting things: - Bridging connections which would otherwise be blocked by a firewall - Tunneling through RDP (similar to an SSH tunnel) - Exposing a localhost web server to others Key features I put effort into: 1. The shared file is restarted every 10 MB, so it doesn't grow indefinitely. 2. Optimisations for latency & bandwidth. (800 Mbps on a Gigabit LAN. 108 Mbps if file tunneling through RDP) 3. Synchronisation between two sides (each side can be started and restarted in any order) I'd love to…

    Hi HN, I'm Tyler Flint, one of the creators of qtap. For a while now, my team and I at Qpoint.io have been grappling with the challenge of understanding what's actually happening inside the encrypted traffic leaving our production systems. Modern apps rely heavily on third-party APIs (think payment processors, data providers, etc.), but once TLS kicks in, figuring out exactly what data is being sent, identifying PII exposure, or debugging integration issues becomes incredibly difficult without resorting to complex and often brittle solutions. Traditional approaches like forward proxies…
