Convert Fedora Workstation to Fedora Server

So, you installed Fedora Workstation on your server and ended up not using the desktop environment after all and want to convert to Fedora Server without doing a re-installation? It's very easy to do:

Boot to console: systemctl set-default multi-user.target
Change identity: dnf swap fedora-release-identity-workstation.noarch fedora-release-identity-server.noarch

It might take an update of the kernel before the server calls itself "Fedora Server".

While it is possible to completely remove a desktop environment, things could break:

CachyOS Kernel for Fedora with Secure Boot

Did you just install kernel-cachyos and got hit by bad shim signature when booting? Me too. This is how I fixed it.

First, make sure you have Secure Boot with mokutil --sb-state.

Note, there's a second way of doing this by using sbctl, but I didn't want to wipe my Secure Boot keys.

Need help? Feel free to leave a comment below, contact me (@mikaeldui) on the CachyOS Discord, or send me an email.

UniFi: DNAT to redirect DNS requests

You have a local DNS server (e.g. your UniFi router) and want all your devices to use it, even though some don't care which server your router specifies in DHCP replies (e.g. IoT devices)? You can use DNAT to redirect all requests ment for external DNS servers to your local (or favourite remote) DNS server.

What's DNAT?

I guess you know what port forwarding is: you have a single public IP address shared by 10s of devices. In order for devices on the internet (e.g. your friends) to be able to access a device on your local network (e.g. your Jellyfin server) you need to tell your router to forward incoming traffic for a port to a local IP
