The Linux User Net

Please join our weekly Linux User Net every Monday from 8:10PM-9:00PM PST.

The primary purpose of this Net is to share Information about Linux operating system in regards to Amateur Radio use.

Our primary linked repeaters are; 147.32 and 442.325, 444.125 and 147.040 megahertz all having a 100.0 hz tone on The Amateur Radio Relay Group (ARRG) System.


Round Table Discussion Format

If may have noticed less links to Net Control Notes toward the end of 2019. This is because we have shifted our format of the net control station from presenting a specific topic to an open round table discussion.

The open round table discussion is more engaging for our net participants and gives them a more active role in the net, rather than us a teaching role. 

So moving forward in 2020 this is the way our net will continue, so if we do have any pertinent links or information we get from a round table session, then we will post them here under the proper date of that net.

Net Control Stations

Russ – KC7MM – 1st Monday of The Month. Russ is our Assistant Net Manager.

Mark – KC7NYR – 2nd Monday of The Month. Mark is our Net Manager.

Mike – KA7PLE – 3rd Monday of The Month.

Yuuki – K7SAK – 4th Monday of the Month.

Roy – KI7PKL – Alternate.

I would like to personally thank each of our Linux Net Control stations for joining our team. Its a honor and pleasure learning and growing together in regards to Linux and Amateur radio! 

If you are a Licensed Amateur Radio operator and like to become a Guest Speaker on The Linux User Net, visit our Linux User Net Guest Speaker page and fill our the registration form.

The West Side Mesh Networking Project has been discontinued. I made this decision based on our inability to keep the project going. We just don’t have the bandwidth at this time.


What is Linux?

Just like Windows XP, Windows 7, Windows 8, and Mac OS X, Linux is an operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply – the operating system manages the communication between your software and your hardware. Without the operating system (often referred to as the “OS”), the software wouldn’t function.

The OS is comprised of a number of pieces: 

  • The Bootloader: The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system.
  • The kernel: This is the one piece of the whole that is actually called “Linux”. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the “lowest” level of the OS.
  • Daemons: These are background services (printing, sound, scheduling, etc) that either start up during boot, or after you log into the desktop.
  • The Shell: You’ve probably heard mention of the Linux command line. This is the shell – a command process that allows you to control the computer via commands typed into a text interface. This is what, at one time, scared people away from Linux the most (assuming they had to learn a seemingly archaic command line structure to make Linux work). This is no longer the case. With modern desktop Linux, there is no need to ever touch the command line.
  • Graphical Server: This is the sub-system that displays the graphics on your monitor. It is commonly referred to as the X server or just “X”.
  • Desktop Environment: This is the piece of the puzzle that the users actually interact with. There are many desktop environments to choose from (Unity, GNOME, Cinnamon, Enlightenment, KDE, XFCE, etc). Each desktop environment includes built-in applications (such as file managers, configuration tools, web browsers, games, etc).
  • Applications: Desktop environments do not offer the full array of apps. Just like Windows and Mac, Linux offers thousands upon thousands of high-quality software titles that can be easily found and installed. Most modern Linux distributions (more on this in a moment) include App Store-like tools that centralize and simplify application installation. For example: Ubuntu Linux has the Ubuntu Software Center (Figure 1) which allows you to quickly search among the thousands of apps and install them from one centralized location.
