Show HN: Public SSH Jump and Port Forwarding Server I've made a neat service to access SSH over NAT. Unlike ngrok and alternatives with registration, custom software, non-preserved random URLs and ports, this solution is just a remote SSH server which does not require anything more than an SSH client to both host and connect. Technically it allows to publish any service over SSH (web, proxy, any TCP port really), but only with SSH as a destination you'll preserve end-to-end encryption and won't allow my server to snoop on potentially unencrypted traffic. The service is mostly intended to give remote access to the device as fast as possible, given it already has SSH client and server. To begin, just execute: ssh ssh-j.com Would be grateful for any feedback. ----- Looking for ways to expose SSH behind NAT? Search no further! Publish SSH server port of your laptop, which is behind NAT: ssh any-username@ssh-j.com -N -R laptop-behind-nat:22:localhost:22 ╭─╯ unique ╰─╮ │ device name ╭───╯ │destination│ │ namespace │ │ and port │ │address and│ │for your hosts│ ╰──────────────╯ │ port │ ╰──────────────╯ ╰───────────╯ Connect to the published SSH: ssh -J any-username@ssh-j.com laptop-behind-nat ↖ It's THAT easy! Published hosts are bound to the username. Other usernames can't access them. Pick a unique username (not root ) and get access to your devices anywhere! March 18, 2021 at 12:31PM
Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
