What it does
Run curl qsa.sh for a one-command external security scan of your server's own public IP — naabu, nmap + vulners, and nuclei map your open ports, service versions, and known CVEs, streamed straight to your terminal in ~30 seconds. See exactly what the internet sees of your host: no account, nothing stored. Free scans run live; paid Pro (all 65,535 ports, async) and one-time Deep (the full nuclei firehose, emailed) dig deeper uncovering vulnerabilities below the surface.
Run curl qsa.sh for a real external port and vulnerability scan of your own IP — naabu, nmap and nuclei, streamed to your terminal in ~30 seconds. Nothing to install.
Run one command. qsa.sh runs a real external port and vulnerability scan of the public IP you’re connecting from — naabu, nmap and nuclei, streamed to your terminal in about 30 seconds. Nothing to install, nothing stored. The terminal above is an illustration; the countdown and timings are condensed for display. The real scan gives you a full 15-second window to press Ctrl-C. curl qsa.sh connects over plain HTTP; run curl https://qsa.sh to encrypt the scan. Scans only the IP you connect from — the one shown in the warning before the scan starts. You must be authorized to scan it. Known CGNAT and mobile-carrier connections are refused, along with IPv6 and ones our data flags as a…from qsa.sh

IP Guide – Info on IP addresses, Networks, and ASNs2023 · ip.guide · ▲363Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.
I integrated my from-scratch TCP/IP stack into the xv6-riscv OS2025 · github.com · ▲147Hi HN, To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP/IP stack. I'm excited to share the result: my own from-scratch TCP/IP networking stack running directly inside the xv6-riscv (https://github.com/pandax381/xv6-riscv-net) kernel. The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine. Key features: - From-Scratch Stack: The core is powered by microps…
Confidential computing for high-assurance RISC-V embedded systems2025 · github.com · ▲103Dear HN community! Looking forward to hearing your feedback on ACE (assured confidential execution), technology that implements VM-based trusted execution environment (TEE) for embedded RISC-V systems with focus on a formally verified and auditable firmware. We target high-assurance systems that can benefit from compartmentalization and hardware-backed isolation. The key ingredient called security monitor (firmware) is implemented in Rust. The formal specification is defined as annotations directly in code and gets translated to Coq using RefinedRust automation. ACE design is now part of the…
- TYTest your WireGuard connectivity and see global stats, no client needed2024 · probe.sh · ▲43
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…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
