Welcome to the Dayton Linux Users Group

JMB will demonstrate a method of doing encrypted offsite backups. Specifically, how to rsync your computer’s data to a remote Raspberry Pi 4 running Ubuntu, with a LUKS encrypted NFS mounted SSD, using ssh tunneling, port forwarding & ufw firewall protections.

As always, we’ll also have discussion time for Linux and Open Source news, projects you’re working on, and questions for the rest of the group.

We don’t have any specific topic for this month, so let’s just have an open discussion time. Linux and Open Source news, projects you’re working on, and questions for the rest of the group – it’s all fair game! If you have ideas for future programs or activities, we’ll have time to talk about those as well.

Let’s talk about home labs! Or home file servers, media servers, gaming rigs, firewalls, Pi-holes, VPNs, etc. etc.

What computing infrastructure do you have in your house? What works great, and what are the pain points? Any future plans? We’ll all do a bit of show and/or tell about our personal tech and see if we can all get some inspiration (or learn some lessons!) from our fellow geeks. Come prepared to describe your home setup, and feel free to share pictures or take us on a remote tour if you want.

As always, any news, discussions, and questions about Linux / open source topics are welcome.
