Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:

Problem

If you use Cloudflare's DNS (1.1.1.1), then the popular web archive archive.today (and the related sites archive.ph, archive.is, archive.li, archive.vn, archive.md, and archive.fo) will either fail to resolve, or show an infinite CAPTCHA loop. If it does resolve when you're on Cloudflare's DNS, you may have the domain locally cached.

Solution

Fix this problem by:

Configuring dnsmasq on your local DNS server to use an alternate DNS server for archive.today (see comment from @joshenders below), or
Connecting to a VPN before connecting to archive.today (only works if the VPN uses different DNS servers), or
