Debian 13 trixie upgrade

Debian 13

Caution Upgrading from Debian 12 to Debian 13 on machines with mdadm has intermittently failed for me; symptom is that grub EFI is not up to date and system boots into BIOS. Root cause under investigation; it might not be related to mdadm.

To start, read the official release notes.

If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 13 "trixie" from Debian 12 "bookworm" can be helpful. 3rd-party repos are handled with a find command.

Note upgrade is only supported from Debian 12 to Debian 13. If you are on Debian 11, upgrade to Debian 12 first. Then once on Debian 12, you can upgrade to Debian 13.

Debian 12 bookworm upgrade

Debian 12

To start, read the official release notes.

If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 12 "bookworm" from Debian 11 "bullseye" can be helpful. 3rd-party repos are handled with a find command.

Note upgrade is only supported from Debian 11 to Debian 12. If you are on Debian 10, upgrade to Debian 11 first and make sure to change the security repo as per the release notes. Then once on Debian 11, you can upgrade to Debian 12.

Cloudflare Tunnels/`cloudflared` on Mikrotik RouterOS 7

Why?

In their own words:

Cloudflare Tunnel provides you with a secure way to connect your resources to Cloudflare without a publicly routable IP address. With Tunnel, you do not send traffic to an external IP — instead, a lightweight daemon in your infrastructure (cloudflared) creates outbound-only connections to Cloudflare’s edge. Cloudflare Tunnel can connect HTTP web servers, SSH servers, remote desktops, and other protocols safely to Cloudflare. This way, your origins can serve traffic through Cloudflare without being vulnerable to attacks that bypass Cloudflare.

Beyond cyberattacks, this can be particularly useful if you're behind CGNAT, e.g. on cellular or satellite, and you want to make services on or behind your router available to the broader world.

How?
