The ./interfaces is a file. It sounds like /etc/systemd/network/99-default.link is the one you're after. What's the content?

Context is I want to see if the Pi actually has a static IP or not.

I haven't got a Bookworm machine, I may spin up a VM later.

but Netplan needs to die.

Couldn't agree more, it makes things unnecessarily complicated.

If I type 'cat /etc/systemd/network/99-default.link' into Putty nothing happens, just another line in the command prompt.

systemctl status systemd-networkd results in....

I'm remembering correctly that you are running RasPi OS Lite (Bookworm), yes? I haven't run ROS in years, I ran FreeBSD for a long while then moved to AlmaLinux. Having just searched it up, it seems after deprecating dhcpcd in Bullseye, they (Raspberry Pi Foundation) moved to a weird mix of Netplan and NetworkManager. There's a YAML on the /boot that can init the network using NM via Netplan, but it's all very unnecessarily complicated and convoluted. You could just set up systemd-networkd and disable everything else, or just set up a static IP via nmtui (graphical in console) or nmcli. Just to confirm, what's the output of systemctl status NetworkManager?

Throrik · 2025-01-14T08:35:52+0000

Honestly, I would run:

Code:

cat /etc/os-release

This will tell us which exact distro/version you're on

For example I am running bookworm for the majority of my Linux servers:

Code:

cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm

and I have had to use /etc/network/interfaces with the minimal netinst most things use. This is the output for a VM, so ignore the vmbr interface yours will be different if it's physical.

Code:

cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.104/24
        gateway 192.168.1.1
        bridge-ports enp1s0
        bridge-stp off
        bridge-fd 0
