How to setup a 64 bit Raspberry Pi with openSUSE
The Raspberry Pi is a great little computer and Raspbian is a wonderful Debian based operating system for it. Raspbian has a graet many uses but one drawback is that while the Pi will support 64-bit software, Raspbian is 32-bit.
For the times that you need a 64-bit operating system on your Pi there is now a solution. OpenSUSE has introduced a 64 bit operating system for the pi.
Below are steps for how you can setup your pi with openSUSE’s 64-bit OS.
Download and flash OpenSuse 64 bit image
Go to to the OpenSuse Raspberry Pi Page and download the X11 image for openSUSE Leap 64-bit for Raspberry Pi. Flash your SD card with flash with etcher.
Boot your pi for the first time
For initial setup you will need:
- USB keyboard
- USB mouse
- Monitor w/HDMI cable
- Micro USB power source
- Network cable
After initial setup we will run it headless so you won’t need a monitor, mouse or keyboard attached.
Additionally, if you want to enable wifi, you can remove the network cable once wifi is enabled.
Connect the HDMI, network, mouse and keyboard and plug in the power. Once it boots you can login with the default login:
- User: root
- Password: linux
You can use your command line text editor of choice, nano may be the easiest to use. If you want to use nano and have connected to your network you can install nano with
sudo zypper in nano
First we will need to get the wifi working. If you are happy to have a network cable running to your pi you can skip this step, but I like to be able to just have power running to mine.
sudo nano /etc/dracut.conf.d/raspberrypi_modules.conf
Remove sdhci_iproc in the first line and uncomment the last line. Save the changes, run the command:
mkinitrd -f sudo reboot
Once you have rebooted, log back in with root:linux
Open a terminal and run
Navigate to System -> Network Settings and you should see the BCM43430 WLAN card entry.
Use tab to navagate to this entry and press enter, then use tab to select Edit and press enter.
Tab to the entry Dynamic Address and press enter.
Tab to [Next], at bottom right of screen and press enter.
Tab to [Scan Network] and press enter
Cycle through tab until you get to the box under Network Name. Press the down arrow and select your wifi network.
Choose your Authentication Mode. My guess is that you have WPA-PSK but your settings will vary.
Enter any additonal info needed such as Passphrase and select [Next]
This will take you back to the network settings page. Select [Ok] and press enter
Testing your wifi
Make sure your network cable is unplugged and type
You should see something like this if your wifi is working
You can press CTRL+C to stop pinging
Now that your network is working, you can go ahead and shutdown your pi
sudo shutdown now
Then you can remove the mouse, keyboard, network (if you configured wifi) and monitor.
Move the pi to your desired location and plug the power back in.
Find IP address
Once you have your rasperry pi setup with wifi (or network cable if you prefer), you will want to find out it’s ip address so that you can connect to it on your network. To do this you will need to login to your router.
Routers web consoles are different, but typically they will be on your network at an address similar to 192.168.0.1 or 192.168.0.100. You can generally find the address for your router model online with a little searching.
Once you are logged in you can find the ip address of your pi. It will likely be something similar to your router address; 192.168.0.xx
Tip: If your router will allow you to bind the mac address of your pi to a specific ip address, this will keep your pi at the same address.
Login with SSH
If you are using Linux of Mac you will likely have an Open SSH Client installed and can use it from the command line. If you are using Windows you will probably want to install Putty or Cygwin to be able to use SSH from your computer of choice to communicate with your pi. If you do find yourself needing an SSH client, there are a number of alternatives to choose from.
I use Open SSH so the examples should work from any Linux or Mac terminal. If you use windows, the examples may differ slightly based on the SSH software you use.
To continue you will need an SSH Client and the ip address of your pi.
ssh root@<ip address of your pi>
Congrats! You are logged in.
Before we look to setup the wallet there are some steps that we will take to setup your pi. The first of these is to set Time and Date settings.
Setting date and time
Select System -> Date and Time
Set your timezone and make sure that Hardware Clock Set to UTC is checked.
Tab to Other Settings and press enter. Check the box next to Synchronize with NTP Server and [Accept] Changes.
You may be greeted with a message that additional packages need to be installed, that is fine let it install them.
Check Run NTP as daemon and Save NTP Configuration when you are done
Pres [F10] to save and exit and [Ok] when prompted at the Date and Time menu
Select [Quit] from the main yast menu when you are done.
You can check the status of ntp with
systemctl status ntpd
Add additional swap space
If you are planning on having your pi do something resource intensive, like running a node or compiling complex code, you will want to have plenty of memory available.
Let’s get some extra resources by adding some more swap space.
su mkdir -p /var/lib/swap dd if=/dev/zero of=/var/lib/swap/swapfile bs=1M count=2048 chmod 600 /var/lib/swap/swapfile mkswap /var/lib/swap/swapfile swapon /var/lib/swap/swapfile
Add the following line to the bottom and save
/var/lib/swap/swapfile swap swap defaults 0 0
Secure your Pi
Since you will be storing value on your pi, let’s take a look at some steps that you can take to secure it. While this isn’t an exaustive list, it is a good start to making your pi more secure
Change your root login
First thing that we want to do is to change the default root password of linux. The root user has access to everything on the system so you will want to make this a secure password.
Use the passwd command to change the password
It will ask you to type your new password twice and give you the message, “passwd: password updated successfully” when it is successful.
Create a non-root user
Next, let’s make a user that does not have root acces, this will be the user that we will use most of the time.
Note: I will use “jproto” as my username in the examples, but you can use your preferred username.
useradd -m jproto
Now let’s set the password for the new user
Let’s quickly switch users to out new user
You are now logged in as your new user
You are now logged back in as root. You will notice that your prompt changed when you are logged in as your new user
Change your host name
One last thing that we can do as root. Pick a host name for your pi. Make it a single lowercase word. I will call my pi, “cersei”.
To do this we will replace the contents of /etc/hostname with the name of our pi.
Edit the contents to your hostname of choice, save and exit nano.
Login with your new user
From now on we will use the new user’s account so let’s logout of root.
You should no longer be connected to the raspberry pi.
Now let’s login to the pi with the new user
ssh jproto@<ip address of your pi>
It will prompt you for a password, use the password that you gave your new user.
We will need to use some basic bash skills for this part. Nothing difficult, just being able to change directories and know where you are in the file structure.
The Command line crash course is a good primer if you need it.
When you are done, go ahead and logout of your pi
Key based authentication
Now we will setup key based authentication. You can skip this step if you like, but it makes for a more secure system. Just remember to back up your keys somewhere safe because you won’t be able to access the pi without them.
Once complete, you can find your keys in the following folder
Here are some references that will help you learn more about key based auth.
- Ubuntu OpenSSH key reference
- Debian - SSH with authentication key instead of password
- Key-Based SSH Logins with PuTTY
Create an rsa keypair
If you don’t already have keys on your own machine you will need to generate them.
ssh-keygen -t rsa
Now copy your key to your raspberry pi
ssh-copy-id jproto@<ip address of your pi>
You should now be able to log into your pi with your key
ssh jproto@<ip address of your pi>
Turn off password based authentication
If you turned on key based authentication, you will want to turn off password based authentication
If you are not already logged into your pi, ssh into it.
Become the root user
Then edit /etc/ssh/sshd_config
Make sure the following lines are uncommented (no # at the beginning) and set as follows
RSAAuthentication yes PasswordAuthentication no ChallengeResponseAuthentication no
Save and exit the file
systemctl restart sshd
You can check the status with
systemctl status sshd
Turn on a firewall
Now let’s install a firewall and configure it to allow us to login via SSH
While you are logged in as root
zypper in ufw
Once it is installed check to see what configurations are available
ufw app list
You should see SSH in the list. Let’s allow SSH through the firewall
ufw allow SSH
Now enable the firewall
You can check on the status of the firewall with
Update your pi
Now that we have a non-root user, a firewall and can connect via rsa keys, let’s update with the latest software.
This is always a good idea to keep security patches up to date.
Once done isntalling, go ahead and shut down and log back in to make sure that everything is working.
