Thunderbolt Networking Setup on Linux

This guide documents the steps to enable and configure Thunderbolt networking on your Linux system (e.g., Ubuntu, Proxmox). It covers loading the necessary kernel modules, ensuring persistent interface naming, configuring a fixed IP address, and testing throughput with iperf3. Note that Thunderbolt 3/4 hardware advertises a raw bandwidth of 40 Gbps, but practical throughput is typically lower due to half‑duplex operation, protocol overhead, and system constraints.

Hardware Used in This Guide

This guide was developed and tested with the following hardware:

• CPU: AMD Ryzen 9 PRO 6950H
  • 8 cores / 16 threads
• 3.3 GHz base frequency / 4.94 GHz boost

Fish Shell With Starship on Windows Git Bash

Why go through all these steps? Make things easier and simply use the 4devs menu in 🚀 All-win-1 🚀 to get it done effortlessly

Old/Manual Mode

1. To install fish shell on Windows Git Bash, install Git and MSYS executing the following commands in powershell:

Thunderbolt Networking

this gist is part of this series

you wil need proxmox kernel 6.2.16-14-pve or higher.

Load Kernel Modules

• add thunderbolt and thunderbolt-net kernel modules (this must be done all nodes - yes i know it can sometimes work withoutm but the thuderbolt-net one has interesting behaviou' so do as i say - add both ;-)
  1. nano /etc/modules add modules at bottom of file, one on each line

2. save using x then y then enter

ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

# This kubernetes manifest for http://github.com/atmoz/sftp is made by ToMe25, based on a similar one by jujhars13.
#
# Usage:
# 1. Create the sftp namespace using `kubectl create namespace sftp`.
# 2. Copy your `~/.ssh/id_rsa.pub` file(can be generated with `ssh-keygen` if missing) to a new folder named `client_keys`.
#    Also add the `id_rsa.pub` files of all other users you want to be able to log in without a password to this folder.
# 3. Create host keys for the sftp server in a new folder named `host_keys` by running `ssh-keygen -t rsa -b 4096 -f ssh_host_rsa_key`
#    and `ssh-keygen -t ed25519 -f ssh_host_ed25519_key` in it.
# 4. Create a Kubernetes secret from the client keys by running `kubectl create secret generic sftp-client-public-keys -n sftp --from-file=client_keys`.
# 5. Create another Kubernetes secret from the host keys by running `kubectl create secret generic sftp-host-keys -n sftp --from-file=host_keys`.

BACKGROUND (WHY?)

I switch dev-environments every single year with each customer having their own setup. Git on Linux and MacOSX just works most of the time - there are some SSH keys needed to be setup, but "sudo apt-get" or "brew install" mostly does the trick.

Git for Windows is a box a sourcery, so when you install that you will get a version of slim MSYS2, MinGW64 and most importantly bash and git that runs from the bash. This is what you need 9 out of 10 times, if you ONLY need to use git to manage your source and then use other/external toolchains like VS Code, VS2022 or Windows Powershell or Command to compile your sh.ttt I mean stuff.

Then that 10th out of 10 times, you want to compile windows applications from the same terminal that you run git - just like you do on linux or OSX. If you are running Windows alone then having two terminals, one for git (with mingw64/msys2) and one for your ms whatever the compiler name is for C++.

Using fish shell with git bash on windows

To install fish shell on windows the options are:

• Cygwin
• WSL
• MSYS2

Since git bash is based on MSYS2 it seems a good fit to install fish. The problem is that git bash is a lightweight version of MSYS2 which does not include pacman as a package management, used to install fish.

This OS thread has great suggestions on how to solve this problem including using the full MSYS2. But the best solution for me was this answer by Michael Chen which installs pacman on git bash.
