As a member of the Fedora Linux QA team, I sometimes find myself executing a bunch of commands that I want to broadcast to other developers. If you've ever used a terminal multiplexer like tmux or GNU Screen, you might think that that's a relatively easy task. But not all of the people I want to see my demonstration are connecting to my terminal session from a laptop or desktop. Some might have casually opened it from their phone browser—which they can readily do because I use tmate.

Virtual Network Computing (VNC) is a desktop sharing protocol that allows you to control a computer remotely using the VNC client software. In this tutorial, we will show you how to install and configure the VNC Server on the latest Ubuntu Server 22.04.

Automating repeatable tasks is a core part of a sysadmin's daily routine. Increasingly, this automation involves interacting with web-based APIs to orchestrate activities across devices, cloud providers, or software-as-a-service (SaaS) tools. You must thoroughly test your code, whether you're writing shell scripts or Ansible playbooks that interact with web services.
