SSH commit verification now supported - GitHub Changelog
GitHub now supports SSH commit verification, so you can sign commits and tags locally using a self-generated SSH public key, which will give others confidence about the origin of a change you have made. If a commit or tag has an SSH signature that is cryptographically verifiable, GitHub makes the commit or tag "Verified" or "Partially Verified." If you already use an SSH key to authenticate with G

Linux has been bitten by its most high-severity vulnerability in years
Linux has yet another high-severity vulnerability that makes it easy for untrusted users to execute code capable of carrying out a host of malicious actions, including installing backdoors, creating unauthorized user accounts, and modifying scripts or binaries used by privileged services or apps. Dirty Pipe, as the vulnerability has been named, is among the most serious Linux threats to be disclos

A jump-host SSH server that starts machines on-demand
LazySSH LazySSH is an SSH server that acts as a jump host only, and dynamically starts temporary virtual machines. If you find yourself briefly starting a virtual machine just to SSH into it and try something out, LazySSH is an attempt to automate that flow via just the ssh command. LazySSH starts the machine for you when you connect, and shuts it down (some time after) you disconnect. Another pos

GitHub - mikroskeem/tosh: Imagine your SSH server only listens on an IPv6 address, and where the last 6 digits are changing every 30 seconds as a TOTP code...
This was made because... I could make it, not if I should make it. Yes, you read it right - it's a toy. Only use it if you know what you are doing. I am not up to handholding, preventing any footguns nor basic support requests. Its purpose is just to add a layer of obscurity, it's probably only effective against bots (allthough most of them disappear after moving on to IPv6) and script kiddies. If
