Products that do what Master SSH tunneling in an interactive lab does

A little over a year ago I gave away over 4,600 copies of my intro to SSH tunneling book, The Cyber Plumber's Handbook, for free over a 48 hour period to the awesome folks here on Hacker News (https://news.ycombinator.com/item?id=19946941). Since then, I've been getting a lot of feedback about creating an interactive lab where SSH tunneling and port redirection techniques can be practiced in real scenarios. With a bit more time during the quarantine, I finally found the time to launch the lab portion. For the HN family, I'm offering the book and 2 weeks of lab time for 50% off…

    Looking to get some feedback from the Hacker News community. I wrote the book with a focus on penetration testers and red teamers, but there are great examples for network admins, developers, and blue team defenders as well. You can pick up a copy for free here through May 19, 2019: https://gumroad.com/l/the_cyber_plumbers_handbook/hackernews... Please note, because it's hosted on Gumroad, it does require an email. If you don't want to give out your actual email, check out an anonymous email service. I give it away to students for free, so if you know of one that…

    I put this together since I find myself switching away from the terminal to see if anything new popped up in HN. There might be similar ones out there, didn't bother looking. It was a quick experiment, which might end up with a few more features.

    I built a realistic prod system under heavy pressure where you SSH in and solve real problems. You get your own server (real box) and have to fix various things up under fire. a friend told me it reminded them of DOOM for SREs, another called it a "flight simulator" because you can do anything (and reboot if you crash). someone else said it was like "an escape room for engineers", in that you have to find your own way around an unfamiliar box and solve puzzles. idk, maybe it's fun. try it! how it works: you get two Hetzner servers: a traffic generator (real traffic from NYC taxi data highly…

    Hey Hackernews! My names Olly (a Designer from the UK). I’ve been a long time lurker on Hackernews but now I finally have something to share with the community. Along with my friend Oliver (Developer, Sweden/Japan) we have been working on Remotewise.io. It’s a new resource and learning platform dedicated to remote work. We’ve both been working remotely for most of our careers. Over this time remote work has been gaining huge momentum as a viable and desirable way to work and we believe it’s the future. We’ve been working on this during our evenings and weekends in between our full-time…

    Hello HN! Here's my November Startup Sprint project (coded in two days). http://hackerlunch.com It allows you to post your lunch plans and lets other hackers join you. I built this because I often see HN users are interested in meeting each other if they are in the same area. I am not a coder, so this version is very rough. If people use it, I will work with others to build a more polished version. I would love some feedback. What do you think? Is this something you will be using?

    Hello HNers. I'm launching my new service, Certician, and I'd love some feedback from HN users. A while back, I asked if anyone knew of any good, simple tools or services for monitoring SSL certificates [1]. I didn't find any compelling services, so I decided to build one. I tried to keep it simple, since it's self-run and bootstrapped. I know my landing page needs help. It's a lot harder to distill down a service (even a simple one) into compelling, actionable copy than I thought! I have to work at my real job today, so I'll only be able to reply when I have time to take a break for a…

    I want to share a new dataset of 331 reward-hackable environments. These are real environments used in Terminal Bench and adjacent benchmarks. I first got interested in this because, as a reviewer of Terminal Bench, I noticed a lot of our tasks were hackable. I also noticed that many contributors to the benchmark do so because it provides credibility when selling environments to labs. Hence, TBench tasks are, in my opinion, held to a higher quality standard than those being used today for RL. No one is spending hours manually reviewing the $1B in tasks being purchased by major labs. As far…

    Hi HN! I'm Nick, one of the cofounders of Bitping, and we'd like to share a tool that we've been working on for the past couple of years that lets you test network connectivity from real user devices around the world. We originally were part of a hackathon focused on building a product that is powered by micropayments and we settled on a network that could ping other network devices and users could be paid in fractions of a cent for performing said work. After winning the hackathon, we built an uptime monitoring service and discovered some discrepancies between our data and traditional…

    http://ghn.cloudapp.net/ If you can, try right-clicking on an image. This page started off as a random collection of stuff I wanted to try out (spinning up an Azure linux VM included) where I gave myself "1 hour per feature" to learn new stuff. Shell scripts, command-line webkit-based png rendering, pcntl_fork, piwik... Fun stuff. I know, yet another view of HN, no biggie. I welcome all feedback and questions!

    Is anyone else on HN participating in this FCC research project to measure broadband performance? [1] I signed up for more information when the project was announced, some time ago, but a few days ago the device arrived. Technically, it is quite an interesting little box. It's a generic consumer device, shaped like a wireless router, with an antenna and five RJ-45 jacks. But it works more like a bridge, plugging in between my existing ADSL modem/wireless-router and any wired devices that used to be plugged directly into the existing ADSL. No changes needed to be made to any of the…

    Hello! I just published a book on Site Reliability Engineering. https://www.amazon.com/dp/B09QNZC2LL This book is a collection of 28 chapters on SRE concepts, such as observability, monitoring, Service Level Objectives (SLOs), alerting, resilience and debugging. I adapted each chapter from blog posts I've written over the last 4 years. Most of the chapters detailed concepts that I applied while working at $dayjob, so they are 100% proven in real business settings :) ------ Some info on the backstory. Last year I started writing a book on my software development…

    Hey all. Today the book on remote working that I wrote for The Pragmatic Bookshelf has gone into beta. It's called Effective Remote Working. I didn't plan on writing a second book, but 8 months ago during a conversation with the publisher we agreed that it was the right time for a book like this. My first book was Become an Effective Software Engineering Manager, which I did a Show HN on before: https://news.ycombinator.com/item?id=22033129 That book has so far been successful with lots of great reviews and over $100,000 in net sales. A beta book with PragProg means that you…

    HN has been a destination on the Web for me recently, but I've had trouble really _getting into_ it. I realized that was because there wasn't an intuitive way for me to browse through articles, comments and authors. I started working on a GreaseMonkey script for myself and, as I got into it, decided I would share it with others who may be interested. SuperHN keeps everything on one page and adds keyboard navigation. 'W' and 'S' browse through articles, 'A' and 'D' cycles through an article, its comments and poster. It also makes the front page a bit more readable. You can get Super Hacker…

    hey all, happy to share research i've been working on for islo.dev in recent months. ever since the cheating agents (https://debugml.github.io/cheating-agents/) paper came out, revealing reward hacking was 4x more prevalent than previously estimated, i've been looking into how we can deal with the issue the common approach (taken by the tbench team) is post hoc trajectory analysis. i've been interested in the idea of reframing the problem as an endpoint security problem and tackling it via sandbox i hope you find it interesting, and thanks to the islo.dev team for…

    Hi HN, I'd like to share a small Go utility I wrote called prxy. The idea was born out of my frustration with accessing my self-hosted services when I'm on the go. I use WireGuard to connect to my homelab, but I really dislike sending all my computer's traffic through my home network — it slows things down and is inconvenient. I wanted proper application-level split-tunneling. A tool I love, wireproxy, got me most of the way there by creating an HTTP proxy from a WireGuard peer. This is perfect for apps that let you configure a proxy. The problem was the other 10%: apps that don't. Think of…

    For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features: - AI-powered presence to represent you when you’re offline. - Live video streaming to showcase your work in real time. - VS Code integration to broadcast your status live. - GraphQL API for full customization and hackability (such as using your own agents) - Web3 donations to support and get support from other builders. In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with…
