The telnet utility, a once common protocol that graced the terminal of every system administrator and power user, was a precursor for the SSH protocol. Since telnet sends all data, including usernames and passwords, over the network in clear text, it is not often used anymore. Despite the other protocols that have come to replace it, telnet remains an ideal utility to test the connection to a certain port of a device, and can be handy in other niche scenarios, or even send an email.

How to paste into terminal
Linux users that are new to using the command line terminal will quickly realize that the typical and well known Ctrl + C and Ctrl + V keyboard shortcuts do not work for copying and pasting. Instead, Ctrl + C will interrupt a running command, so users must quickly make new habits and learn the proper way to copy and paste into the terminal. In this tutorial, we will show you all the ways to paste your clipboard into the terminal on a Linux system. We will also go over a few ceveats that you may need to know.
How to pipe output to a file on Linux
When using the Bash shell on a Linux system, we can send the output of a command to somewhere else, by passing it to another command or a file, for example. This is called Bash shell redirection. It is useful in many different scenarios, and is one of the most basic and essential components of learning to use the Bash shell and Bash scripting.
How to scroll up in terminal on Linux
The command line is the most powerful feature of a Linux system, as it allows users to quickly accomplish tasks that would usually take longer using a GUI. In order to be more efficient with using the command line terminal, it is important to know how to navigate around it more quickly. In this tutorial, we will show you how to scroll up in the terminal on a Linux system. This will work for systems that are not using a GUI, such as when logged into an SSH session.
How to switch user on Linux
Linux is a multi user operating system, meaning that it supports having multiple simultaneous user accounts. Some Linux systems may have a few different accounts, and others could have hundreds, depending on the purpose of the system. Switching between user accounts is a common task for Linux administrators who are in charge of user account management, as it allows them to test permissions or troubleshoot problems.
Kubernetes vs Docker, what’s the difference?
Kubernetes and Docker are two names that often get lumped in together. If you are new to containerization technology, you might be wondering what these two technologies do, how they are different from each other, and how both of them fit into the puzzle to tackle a single goal. Both of these tools are important and relevant to system administrators, and are often employed on a Linux system.
Choosing a Kubernetes Networking Addon
Deploying a network addon in your Kubernetes cluster will enable communication between different components within the cluster. A network addon can route traffic between nodes, allowing pods in the cluster to send and receive traffic. Load balancing and service discovery are also made easier thanks to networking addons, but each addon comes with its own networking model and configuration. In this tutorial, we will go through a list of networking addons for Kubernetes to help you choose the best one for your needs.
What is Kubernetes used for?
Kubernetes is container orchestration software that allows us to deploy, manage, and scale containerized applications. It has gained a lot of traction over the recent years and has become the most viable way to horizontally and vertically scale applications, even outperforming traditional methods such as virtualization. Kubernetes was originally developed and used by Google, and has since been taken over by the Cloud Native Computing Foundation (CNCF).
kubeadm vs minikube, pros and cons
Once you start looking into creating a Kubernetes cluster to run your containerized applications, one of the first decisions you need to make is what tool to use to run your cluster. Two of the most popular choices for running Kubernetes on a Linux system are kubeadm and minikube. Each one has their pros and cons, and fills a certain niche that the other does not.
MX Linux vs Ubuntu
MX Linux has quickly risen in popularity in recent years and is one of the most trending Linux distributions currently. Since most Linux users are very familiar with Ubuntu Linux already, it is common to use it as a base for comparison to other distros like MX Linux. Knowing how these two distributions stack up and compare to each other can lead users to a reliable conclusion about which one would be the best for their preferences and workflow.
Linux Configuration files: Top 30 most important
Linux is a powerful and flexible operating system, and one of its strengths is the abundance of configuration files that allow you to customize its behavior to your needs. In this article, we will be taking a closer look at some of the most important and widely-used Linux configuration files. From setting environment variables to managing authentication, these files play a critical role in ensuring that your Linux system runs smoothly and securely. Whether you’re a seasoned Linux administrator or just starting out, this article will provide valuable insights into the inner workings of the Linux operating system.
Linux GUI text editors
Many Linux users like to stick to the command line whenever possible, even when editing documents. However, a GUI based text editor is much better suited for certain types of document editing, such as for a school paper or other lengthy document. A GUI text editor allows us to visualize the paper as it would appear once printed, and see where each new page is separated.
