Determine OS

$ hostnamectl
 Static hostname: pi-server
       Icon name: computer
      Machine ID: a3e83f5bda884aa685532bf63809cb3f
         Boot ID: ce0dfa377b234aa38af1243a20591d0a
Operating System: Debian GNU/Linux 12 (bookworm)
          Kernel: Linux 6.1.0-rpi7-rpi-v8
    Architecture: arm64

Set a static IP on Bookworm

With the release of Raspberry Pi OS Bookworm, networking on the Raspberry Pi was changed to use NetworkManager as the standard controller for networking, replacing the previous dhcpcd system. NetworkManager includes a command line tool called “nmcli,” which can control NetworkManager and report on the network status.

  1. Get name of the device
$ sudo nmcli -p connection show
======================================
  NetworkManager connection profiles
======================================
NAME                UUID                                  TYPE      DEVICE
------------------------------------------------------------------------------------------------------------------
Wired connection 1  77fec910-9ee6-31d0-8aeb-fd3f833bff71  ethernet  eth0
lo                  a4d7024d-0288-4ff5-bda7-0005526414cd  loopback  lo
  1. Three commands to set the new IP address, Gateway and DNS server.
sudo nmcli c mod "Wired connection 1" ipv4.addresses 10.0.0.3/24 ipv4.method manual

sudo nmcli con mod "Wired connection 1" ipv4.gateway 10.0.0.1

sudo nmcli con mod "Wired connection 1" ipv4.dns "10.0.0.1"
  1. Restart the network connection with the following command.
sudo nmcli c down "Wired connection 1" && sudo nmcli c up "Wired connection 1"

Set a static IP on Bullseye

You need some data first. So get the following

# Name of your network card
ifconfig

# Get the DNS server IP
cat /etc/resolve.conf

# The Gateway IP
route -n

Now edit your DHCPD configuration file

sudo nano -w /etc/dhcpcd.conf

Scroll down to the Example static IP configuration section and uncomment out the lines

# Example static IP configuration:
interface eth0
static ip_address=192.168.0.10/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
static routers=192.168.0.254
#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1

Reboot the Pi and connect on the static IP

sudo reboot
