How to List All Running Services Under Systemd in Linux

Filed under
HowTos

A Linux systems provide a variety of system services (such as process management, login, syslog, cron, etc.) and network services (such as remote login, e-mail, printers, web hosting, data storage, file transfer, domain name resolution (using DNS), dynamic IP address assignment (using DHCP), and much more).

Technically, a service is a process or group of processes (commonly known as daemons) running continuously in the background, waiting for requests to come in (especially from clients).

Linux supports different ways to manage (start, stop, restart, enable auto-start at system boot, etc.) services, typically through a process or service manager. Most if not all modern Linux distributions now use the same process manager: systemd.

Making openSUSE Multibootable USB from Ubuntu and Install It

Filed under
SUSE
Ubuntu
HowTos

Since long ago I could not make openSUSE multibootable pendrive except in single boot mode. I could not use MultiSystem nor Sundar's MultiBootUSB nor even GLIM. What's more, I could not find any easy tutorial on the net talking about making it. Fortunately, and good news for us, recently I found Aguslr's Multiboot USB (MBUSB) that is able to create it. I have tested it and as I reported few days ago I finished the installation just as perfect as other distros I had with MultiSystem. Now it's my turn to explain how I did that in 4 steps: first, create a Multiboot USB pendrive; second, copy the ISO file to USB stick; third, boot your computer to USB; and fourth, install openSUSE with it. This USB setup can accept other distros to be bootable along with openSUSE. Enjoy!

  • The Linux Foundation’s LF Edge Releases V2.0 of the Open Glossary of Edge Computing

    LF Edge, an umbrella organization within the Linux Foundation that aims to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system, today announced Version 2.0 of its Open Glossary of Edge Computing. This latest version of the Open Glossary adds a year of updates from the edge community while further iterating vocabulary across the entirety of LF Edge projects.

    The Open Glossary of Edge Computing was created in 2018 as a vehicle to organize a shared, vendor-neutral vocabulary for edge computing to improve communication and accelerate innovation in the field. Launched as part of the first annual State of the Edge report, the Open Glossary is now an open source project under the LF Edge umbrella. The Open Glossary 2.0 is available in a publicly-accessible GitHub repo, and the new versions will be included in the State of the Edge 2019 report, to be released later this fall.

    “The Open Glossary of Edge Computing exemplifies a community-driven process to document and refine the language around edge computing,” said Arpit Joshipura, general manager, Networking, Edge, and IoT, the Linux Foundation. “As the diversity of LF Edge increases, we want frameworks in place that make it easy to talk about edge computing in consistent and less-biased ways. It’s imperative the community comes together to converge on a shared vocabulary, as it will play a substantial role in how our industry discusses and defines the next-generation internet.”
