Living and working in an always-connected world means the quality and reliability of your network connection is vital to practically everything you do on your computer or mobile device. Maintaining a quality network connection, and troubleshooting a connection that fails, are basic skills that everyone should, at the very least, be familiar with.

It doesn’t matter if you prefer Windows, Linux or macOS, most operating systems have basic commands to make troubleshooting network issues a breeze.

Do you know how to force an unresponsive Mac to shut down, or how to find the name your computer uses to identify itself to other devices and servers on your local network in Linux? Are you curious to learn which command displays the basic IP address configuration information for your Windows device? TechRepublic is here to help and share even more user-friendly commands for Windows 10, Linux and macOS in this free PDF ebook download.

You might be new to the role of administrator. Or, you might be new to the world of IT, servers, networks, and data. Either way, there’s one tool that you must get to know because one day it could save your company, your data, and maybe even your job.

That tool to which I speak makes it possible to clone your servers. What these tools do is make it possible to create exact clones of your servers or your data, so that, in case disaster strikes, you have a working copy to start from.

Which tool should you use? It should come as no surprise that there are more than enough cloning tools to choose from, some are free (and even open-source) while others have an associated cost and are proprietary. The good news is, either way, you go you’re probably going to wind up with a solution that does exactly what you want—save the day.

This PDF download from TechRepublic Premium helps define what cloning tools are and how to use them best.

Linux is a powerful platform, one that Enterprise businesses of all kinds have grown to depend on. In fact, without Linux, most businesses would struggle to remain as agile and capable as they are. That’s significant, given how competitive the corporate landscape has become. If your business isn’t able to pivot in an instant, you’ll fall behind quickly.

That means your IT staff needs not only have the skills required to deploy and manage the Linux operating system, they also need to understand some of the more important best practices that can help keep those systems running smoothly and securely.

This PDF download from TechRepublic Premium takes a look at some of the best practices you should be applying to all of your Linux deployments, broken down into easily managed categories.

It’s time to party. Linux is 30 years old. What started as a student project by a young Linus Torvalds studying computer science at the University of Helsinki, has become an open source operating system that enterprise businesses around the globe depend on.

It’s massive. It’s crucial. And without Linux, most businesses wouldn’t be nearly as agile, flexible, and reliable.

To wish Linux a 30th birthday, Jack Wallen describes how the operating system changed his life and the business landscape in this free TechRepublic PDF download.

Most everyone in IT knows about the debacle that was Red Hat capping CentOS at the knees. If you’ve been living in a server room for the past year, let me give the quick gist: Red Hat decided to shift CentOS to a rolling-release distribution, CentOS Stream, that now serves as a testing ground for Red Hat Enterprise Linux. What was once one of the most stable Linux server distributions now livest between Fedora and RHEL, so the company can highlight (to the public) what it’s planning on doing with the next release of their flagship OS. What that means is CentOS Stream will no longer exist as the rock-solid platform we all once knew and deployed, but an ever-changing playground for Red Hat’s premier OS. This means businesses cannot effectively rely on CentOS Stream to be stable. In some cases, crucial tools like cPanel have completely withdrawn their support for CentOS Steam.

The importance of that cannot be overstated. Without cPanel support, a large number of businesses have been forced to migrate to other Linux distributions.

But which ones? Because this is Linux and open source, it should come as no surprise that plenty of options have risen from the ashes that was CentOS 8. One such option is AlmaLinux.

Although you might think AlmaLinux is new to the world of Linux, it’s not. This “new” distribution was created by CloudLinux, a company that has a wealth of experience supporting Linux in the data center and within the cloud. This TechRepublic Premium PDF download will tell you all about it.

The writing on the wall has become incredibly clear and Linux administration is in your future. Your company has probably realized just how much money they can save and much more ore agile they can be by working with Linux as a server platform.

Maybe the business is even considering Linux on the desktop. Either way, you know where you’re headed, but you’re not sure how to get there.

Fear not, as TechRepublic Premium has a list of 10 skills you’re going to need to learn, to successfully add Linux admin to your title. But don’t worry, this isn’t just a list of the commands you need to learn (although that’s a part of it). Instead, this list is made up of a variety of skills you’ll need to successfully manage Linux for your company.

Samsung has unveiled the third generation of its Galaxy Z Fold smartphone named appropriately enough the Galaxy Z Fold 3 5G. In many ways, the new phone is similar to its predecessor, the Galaxy Z Fold 2. Both phones offer a hinged foldable design with internal and external screens, 5G connectivity, a 7.6-inch display and a rear triple camera setup. But the Z Fold 3 5G ups the ante with S Pen support, a speedier processor and a somewhat lower price tag.

If you’re new to Linux and open source software, you will quickly find that there are many terms to learn. Or maybe you’ve come across a word or two in your journey and found yourself lost. Fortunately, TechRepublic Premium is here to help you along the way.

We’ve collected more than 40 terms that are commonly used within the open-source and Linux communities; terms that aren’t always in the regular parlance.

Novices take note: We’ve avoided adding commands and applications to this list and stuck with more general terms. Hopefully, this short glossary will help clear your path to Linux administration.

Docker is a collection of Platform as a Service (PaaS) products that make use of operating-system-level virtualization to deploy containers and containerized services. Docker has been around since 2013, so it’s mature enough to handle enterprise-level needs. Speaking of which, you’ll find a few different versions of Docker, such as the community edition, the open-source edition, and even Docker Enterprise.

Learn more about how to install and deploy Docker Engine, which is available free on the Ubuntu platform. And how, with the help of a Docker Swarm cluster, you can scale those deployments with remarkable ease, and make them immediately accessible from the LAN to which they were deployed in this PDF download from TechRepublic Premium.
