  I have to say I wasn't a fan of GNOME at all, I strongly preferred Pantheon from elementaryOS and XFCE as a second option. However with the PaperWM window manager extension the windowing workflows are top notch! Had to shorten the switching animation, and have removed the maximize (instead double click the title bar) and minimize controls (instead super+h to hide), and it's a tidy look. #linux #opensuse

• Setting Up Zero Configuration Networking with Avahi on OpenSUSE

  Sander March 7 at 12:22 pm

  Setting up Bonjour / Zero configuration networking using #OpenSUSE Tumbleweed is a little bit more involved than with some other #linux distros such as Ubuntu. It consists of setting up the avahi service, followed by configuring the firewall.

  Avahi is a free zero-configuration networking implementation, including a system for multicast DNS and DNS Service Discovery.

  It can be installed and setup as follows:

  sudo zypper install avahi avahi-autoipd libavahi-client3 libavahi-common3
  sudo systemctl start avahi-daemon
  sudo systemctl enable avahi-daemon
  sudo systemctl status avahi-daemon
  

  However I noticed that I still couldn't ping any other devices on the network. This is because the default firewall blocks unconfigured services, which makes sense from a security point of view.

  For this we start Yast Firewall

  YaST Firewall is a configuration tool in openSUSE and SUSE Linux that allows users to manage firewall settings, including opening ports and defining security zones. It has transitioned to using firewalld as the default firewall management system, which provides a more user-friendly interface for configuring network security.

  Step 1: List Networking Interfaces

  To begin configuring your firewall, you first need to identify the network interface you wish to work with. Run the following command in the terminal:

  ip link show
  

  This command will display a list of all available network interfaces on your system. Look for the interface name associated with your active network connection; it may look something like wlp3s0 or eth0. Make a note of the correct interface name, as you’ll need it in the subsequent steps to configure the firewall settings effectively.

  Step 2: Configuring the firewall

  Open YaST Firewall, under Interfaces, click custom, then select a zone such as home if you're on a home network, and under Interfaces: type the networking interface name from step 1. Then check that under the networking zone mdns is listed under the allowed column. Accept the configuration changes.

  You should now be able to ping your other devices!

• OpenSUSE Tumbleweed Installation Notes

  Sander January 5, 2022 at 4:49 pm

  For future reference here are some issues I've come across installing and setting up Tumbleweed on my workstation.

  The reason for switching from macOS is that a commercial operating system focused on services builts in too many distractions for me. Also long term the Apple hardware is priced above what I'm prepared to pay, so it makes sense for me to look for an alternative.

  Tumbleweed is a rolling distribution which makes for a long term maintained setup, and packages are tested thoroughly but are quickly updated.

  So far these are just little niggles.

  Day one issues

  • The old Grub menu from my previous Linux installation wasn't wiped, I simply reinstalled making sure all existing partitions were deleted before partitioning.
  • avahi is not allowed to start itself due to security policies. This was because dbus needed to restart after avahi installed configuration into it. I could have rebooted.
  • My Apple Magic Keyboard must be selected in KDE after the installation as it's not an option during the installation routine.
  • Opening ports for OpenSSH means that they're open on the public zone. I didn't realise this as I want to use the home zone as default.Yast Firewall sorted this out.
  • After installing Lutris, Steam and Proton Experimental, certain games would not start, due to missing vulkan drivers. This Lutris Wiki link describes the issue, I had to search Yast Software for vulkan showed I had to install libvulkan_intel and libvulkan_intel-32bit.

  Interesting links

  • There's a nice tiling window manager script for KDE called Krohnkite. Meta-D conflicted with show desktop, after reassigning the latter I still think that shortcut doesn't do anything, though.

  So far so good. The interface is more snappy than macOS and more powerful, and the system is working nicely.

• PHPStorm font rendering on OpenSUSE

  Sander August 4, 2019 at 12:33 pm

  On Ubuntu LTS the font rendering on #PHPStorm 2019.1 looked great by default, but on #OpenSuse Tumbleweed I needed to tweak the settings a little to get the editor to look good. There is conflicting information out there for out of date versions of OpenSUSE and PHPStorm and it took a bit of research to figure out what works for me.

  Under Help | Edit Custom VM Options... I added the following lines:

  -Dswing.aatext=true<br></br>-Dawt.useSystemAAFontSettings=on

  I also set antialiasing (within the main PHPStorm Settings | Appearance menu) to greyscale.

  Finally, I added the Dreamweaver CC colour scheme to the editor by saving the xml file in ~/.PhpStorm2019.1/config/colors/.

  Restart the application and select the color scheme from File | Settings | Editor | Color Scheme

• Fixing Virtualbox host network adapter cannot be created error

  Sander July 27, 2019 at 10:07 am

  If when trying to start a vm, for example using vagrant, you get the error message that the host network adapter cannot be created:

  There was an error while executing `VBoxManage`, a CLI used by Vagrant<br></br>for controlling VirtualBox. The command and stderr is shown below.<br></br><br></br>Command: ["hostonlyif", "create"]<br></br><br></br>Stderr: 0%...<br></br>Progress state: NS_ERROR_FAILURE<br></br>VBoxManage: error: Failed to create the host-only adapter<br></br>VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory<br></br>VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface<br></br>VBoxManage: error: Context: "RTEXITCODE handleCreate(HandlerArg*)" at line 94 of file VBoxManageHostonly.cpp

  Make sure to first start the virtualbox GUI application. It does some extra checks, and sometimes highlights the permission problem:

  In my case (OpenSuse 15.1 Leap), my user was not added to the vboxusers group. Via Yast > Users and Security .... and editing my user account it was a simple checkbox away. Remember to relog.

  If that doesn't work, reloading the kernel extensions could help:

  $ sudo dpkg-reconfigure virtualbox-dkms$ sudo dpkg-reconfigure virtualbox<br></br>$ sudo modprobe vboxdrv <br></br>$ sudo modprobe vboxnetadp

• Stop OpenPGP passphrase prompting on login

  Sander April 20, 2019 at 11:58 am

  As a security conscious person I setup my OpenPGP keys with a passphrase, however on OpenSUSE Leap 15 this causes a login prompt to appear that delays the network connection from initiating. The same issue also blocks software updates and means a browser restart due to DNS cache stopping connections to websites. This is fairly annoying.

  It turns out that this can be fixed by sharing the network connection via Connections > open the connection > General Configuration > All users may connect to this network. This causes NetworkManager to cache the required authorization tokens (this is my understanding).

  Note that other software such as Kontact might set a daemon to startup by default, causing the same prompt. This can be unticked in its settings.

  If everything else fails, then you could remove the passphrase for the PGP key but this is not recommended as this means someone can take on your identity should your key be exposed for any reason.
