Welcome to the Dayton Linux Users Group

Munin is a networked resource monitoring tool that can help analyze resource trends and “what just happened to kill our performance?” problems.

JMB has used Munin successfully for several years to track various systems’ parameters over a period of time. In this presentation, he will demonstrate the use (and possibly an installation) of Munin and what it can display.

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.

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.
