Sat, May 13, 2023 – Projects Day

We will be having a discussion about Projects that we are working on, but haven’t shared with the group. These can be projects that are successful or ones that just didn’t work out and have been abandoned. We’ll enjoy hearing about other’s projects, and perhaps even offer to help.

NetSIG – Mar. 23, 2023

NetSIG is a Special Interest Group focused on computer networking. Building networks for Today and Tomorrow!

Last month we explored MACVLAN interfaces, and how it makes it easier for Linux Containers (LXD).

This month, BRING YOUR PI, and a 32 GB SD Card, and we’ll do a Linux Containers INSTALL FEST on your Pi.

We will be meeting in-person at Quality Foods (small boardroom upstairs), bring a laptop and have Wireshark installed. This will be hands on. PLEASE BRING an ETHERNET dongle/port as we will be ssh-ing into your Pi, and configuring Linux Containers.

Quality Foods View Royal 6:30pm

27 Helmcken Rd #110 · Victoria, BC

Afterword, we will go out for a beer/coffee.

Thu. Apr. 27, 2023 – NetSIG: LXD Installing Pi-Hole in a Linux Container

NetSIG is a Special Interest Group focused on computer networking. Building networks for Today and Tomorrow!

Last month we did the InstallFest for Linux Containers (LXD). This month, we’ll install a popular application, Pi-Hole, in a container on YOUR Pi. With Linux Containers, there’s no need to dedicate a Pi to Apps like Pi-Hole.

This month, BRING YOUR PI, and the LXD 32 GB SD Card, and we’ll do a Linux Containers App installation on your Pi. Also bring a method to SSH to your Pi (e.g. laptop or screen + keyboard).

We will be meeting in-person at Quality Foods (small boardroom upstairs), bring a laptop and have Wireshark installed. This will be hands on. PLEASE BRING an ETHERNET dongle/port as we will be ssh-ing into your Pi, and configuring Linux Containers.

Afterword, we will go out for a beer/coffee.

Sat. Feb 11 2023 – Linux Containers on the Quadra

linux containers

After using Linux Containers (LXD) for a couple of years, Craig will share how to easily get your containers connected to the internet using a MACVLAN interface. No reconfiguration of the host is required. This technique can be used on Pi’s as well as other hosts.

We will set up containers using the MACVLAN network attachment, discuss limitations, and even run LXDware, a web-based GUI for LXD on a Pi.

We will be holding a Hybrid meeting (in-person & Jitsi).

Sat., June 11, 2022 – Marine GPS on a Pi

Dave will share his work in running Marine Navigation on a Pi including:

  • hardware requirements
  • how the zero could be used, but there are drawbacks
  • I was unable to get a pi 4
  • at George’s suggestion, I decided to go with the pi 400
  • hardware modifications to integrate the GPS unit within the pi 400 case
  • introduction to and a brief overview of the OpenCPN Chart Plotter Navigation software
  • some ideas I have to make a more “system-critical” GPS solution (will implement if I have time)
