Saint Louis Unix Users Group

The Saint Louis Unix Users Group (SLUUG) is an IRS 501c(6) designated not-for-profit professional association dedicated to education and communication among computer users. SLUUG members include many Linux and UNIX professionals, Networking experts, System experts, hobbyists, and students. Also, many who are interested in Unix, Unix-like Operating Systems, Linux, BSD and other Free Open Source Software (FOSS) applications, products, projects and services.
We have met continuously since we incorporated in July 1992. All of our meetings are free and open to the public. There is no individual membership fee.

Monthly Technical Presentations

We will open the remote session at about 6:00 PM, Central Time, so that you can join early to test your microphone, screen sharing and video camera .
Then we start at 6:30 PM with our BASE introductory level session ( often focused on personal computing ); which may include either amazing graphical packages, blinking lights, command line wonders, demonstrations of useful applications, displays of newly discovered web sites, major resolution of long standing anomalies, quantum discoveries, smoke and mirrors, superb tutorials, or shifts in both time and space.
Sometime after 7:00 PM we attempt a quick welcome, introductions, announcements, current events of interest, and a general CALL FOR HELP (Questions and Answers) segment.
Sometime after 7:15 PM, we may take a short break before our MAIN topic ( often focused on enterprise computing ).

What!

  • ONLINE sessions only. No physical meetings until further notice.
  • ONLINE session by a remote video meeting service, next on 14 October 2026.
  • Connection instructions will first be sent to our mailing lists and then linked here. .
  • In what order or sequence are meeting events held? SLUUG_Meeting

    • Something fundamental, introductory, instructive, short, simple or small.

    BASE Topic: The -R option in the rsync command

    Presenter: Robert_Citek

    Smarter Copies, Native Paths: Harvesting Scattered Files Using rsync -R.

    When transferring a group of specific files across systems, standard copy routines ( e.g. cp ) collapse directory structures, forcing manual path rebuilding or inefficient bulk transfers ( e.g. tar ). For example, we may want all the README files from the linux source code in a single filesystem hierarchy.

    The rsync --relative (-R) flag solves this by preserving path hierarchies during selective file transfers.

    In this hands-on demonstration, you will learn how to leverage -R alongside utilities like find to streamline targeted documentation and configuration harvests.

    We will:

  • explore core path-preservation mechanics,
  • introduce the /./ path "anchor" technique to prune unwanted parent directories on the fly, and
  • execute a live run gathering scattered README files into a clean, structured hierarchy with a single command.

    • Here's what I'm going to cover in three bash commands, focusing on the third.

    1. $ curl -L -O 'https://github.com/torvalds/linux/archive/refs/heads/master.zip'
    2. $ unzip -q master.zip
    3. $ find linux-master/./ -iname 'readme*' | rsync -vaR --files-from=- . docs/

    A link to the rsync -R tutorial: tutorial

    Then something more advanced, detailed, important, new, profound, significant, timely or useful.

    MAIN Topic: Proxmox - From host power on to VM login

    Presenter: Grant Taylor and Lee Lammert , Omnitec

    Testing Proxmox with Virtualization Machines (VM). Of course this will be pursuant to hardware playing well.

    Searching for and finding hardware in the Bat Cave is always astonishingly pleasant. Lee actually found the video splitter that was used during his last presentation. The hardware setup to connect the DP to HDMI has been completed. Tech begins.

  • come watch the struggle.
  • heckle as we install Proxmox on a test SLUUG virtualization server.
  • Participate as we go from the first power on of the host, all the way through to logging into the first VM.

    POSSIBLE DISCUSSIONS:

  • Future ideas and expansion of PROXMOX.
  • Physical and Virtual hosts.
  • Private and Public containers.
  • Security considerations.
  • Design and Layout (scribble on whiteboard).
  • Measuring and planning storage.
  • The color of the sky and the meaning of Life.
  • Bring your own popcorn.

    We recommend watching ahead, the following suggested: Video

    When!

    Wednesday, October 14th, 2026
