Configuring Cyclone DDS for Wifi + Ethernet connection on an Enterprise Network (for ROS2)

For communication between wifi and ethernet devices, the DDS layer in ROS2 relies on the multicast ability of a given network.

This is often disabled on enterprise networks (at university or work etc) for (I think) security reasons .

To get around this, you have to configure CycloneDDS to comunicate in a unicast manner, and you must specify the local IPs of all the participants you want to communicate.

_I am using CycloneDDS instead of the default (for ROS2 humble at least) FastDDS, because I ran into lots of issues trying to get topic

RetroNAS on Unraid

This guide is intended for installing RetroNAS on an already configured Unraid server. If you're not familiar with Unraid or RetroNAS, head over to the RetroNAS GitHub page to learn about RetroNAS and consider setting it up on a Raspberry Pi.

Unraid NFS Setup

Within Unraid, enable NFS by going to Settings and NFS.

Enable NFS: Yes

Backup a Raspberry Pi to Proxmox Backup Server using the Proxmox Backup Client

This works on a Pi 4, and should work on a Pi 3, but to work on a Pi Zero you would have to figure out how to compile your own client. More info in this thread on the Proxmox forums.

Determine if your Pi is 32bit or 64bit

Run the following command. If you get arm64, it's 64bit, otherwise you'll see armv7l which is 32bit.
