Setting openSUSE mirrors

Well, if you were trying to perform an update or install anything from the repositories last week, you may have noticed that something was wrong. If you ever come over a situation like that, my first advice is to check the following webpage for the openSUSE webservices status: status.opensuse.org. A visit to the status page would give you some idea of what is happening, but not a solution, though.

Upgrading from openSUSE 42.2 to 42.3

In order to upgrade from openSUSE 42.2 to the latest version 42.3, there are several steps that you will need to take for the process to be problem free. Those steps were originally published on the openSUSE SDB webpage, but I decided to output the exact command line commands in here, as I upgraded my office computer from openSUSE 42.2 to 42.3.

Install and setup VirtualBox and KVM on openSUSE Leap

After the previous posts where I showed you how to install VirtualBox and KVM in Debian, it is now time to try this in openSUSE. In openSUSE you can do the setup and installation in two ways, either by command line, or by GUI with YaST. This is the power of SUSE, compared to other Linux distros.

Therefore, here are the steps you need to take in order to install and configure VirtualBox on Debian 9.1 Stretch. FOr example we will install Debian 9 Server and Raspbian Desktop x86 inside the Virtual Machine. Continue reading “Using VirtualBox on Debian 9.1”

Happy SysAdmin day!

Today, July 28, is the SysAdmin day.

Therefore, let’s have a LOUD Happy SysAdmin Day!!! It is a great time to pay tribute to all the sysadmins out there, the ones that keep your systems running and your networks secure! You may be a sysadmin, or someone you know, therefore, you should take them out to have a drink or something, or if not, maybe you should check out the Unixstickers 20% offer for today! Isn’t that cool? You can give your sysadmin a big hug, letting him/her know how much you appreciate his/her work. Don’t be shy.

Therefore, happy sysadmin day, to all of us!

Install and configure Debian 9.1 as your main desktop system.

This is an important milestone in my career, as given some specific professional circumstances, I need to completely focus on Debian/GNU Linux and its derivatives such as Ubuntu, Mint or Kali (this meaning that there will be no more openSUSE stuff for a while on this blog). This is particularly a good thing, as I am already used to Ubuntu as I’m running it since 2010 on some of my systems. But I felt like I needed a change and thus decided to go to the source and use the rock solid Debian 9 Stretch for my main systems.

Setting up a Samba PDC on openSUSE Leap 42.2

Here is a new post with regard to Samba. As we set up a Standalone server based on Ubuntu 16.04 earlier this month, now is time to set up a Primary Domain Controller based on openSUSE Leap. I really don’t know why, but, no matter what I do, I end up using openSUSE. It is the distro of my choice, really. I really like the way the community is developing this particular distro. It is rock solid, easy to use for newbies and professionals alike and it gives you choice for multiple options with regard to the desktop environment and the software to use and setup right from the installation process. Now, lets cut the chit chat and get back to Samba. Continue reading “Setting up a Samba PDC on openSUSE Leap 42.2”
