How To Convert AWS Route53 to Cloudflare Let’s Encrypt DNS challenge with acme.sh
I already wrote about setting up wildcard Let’s Encrypt SSL/TLS with AWS Route53 DNS for Nginx or Apache. One of my clients decided to use Cloudflare CDN and DNS at some point. They changed their DNS to Cloudflare. Naturally, their wildcard certificate failed because it was using Route53 DNS authentication to issue the certificate. Let us see how to convert existing or expired TLS/SSL certification renewal from AWS Route53 to Cloudflare.

Update your nixCraft RSS feed
Many of you access the nixCraft tutorial and blog post using the RSS feed. However, Google decided to kill the last part of Feedburner. Back in the old days, I and many others used FeedBurner. At some stage, Google acquired FeedBurner, and now they are putting it into maintenance mode. Hence, this new change will affect those getting daily emails via FeedBurner when new content is posted here. Therefore I urge you to update your feed.

How to install and upgrade OpenSSH server on FreeBSD
Another day I wrote about setting up ssh public key password-less authentication for FreeBSD server version 12/13 with an optional 2FA hardware USB key (FIDO 2) for additional protection. However, FIDO2 and key type ecdsa-sk and ed25519-sk are not supported by the OpenSSH client and server version shipped with FreeBSD 12 or 13. But, fear not, we can safely upgrade the OpenSSH version using ports collection. This page explains how to install and configure the latest portable version of the OpenSSH client and server on FreeBSD 13.

How to protect Linux against rogue USB devices using USBGuard
{nixCraft Patreon supporters content}You deployed a perfect firewall and other network security policies preventing unauthorized access to the user's desktop computer over a network. However, you still need to block USB device access. We can configure a Linux desktop security policy to protect your computer against rogue USB devices (a.k.a. BadUSB) by implementing essential allow and blocklisting capabilities based on device attributes. For instance, I can define what kind of USB devices are authorized and how a USB device interacts with the Linux system. For example, I can define policy allowing Yubikey with serial number "XYZ" and USB LTE modem with serial # "ABC." Every other USB device access is denied by default. This guide will cover the following topics:
