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

NordVPN Linux CLI: A Comprehensive Command Reference

I. Introduction

The NordVPN client for Linux provides a robust command-line interface (CLI) that allows users to manage their VPN connections, configure settings, and access various features offered by NordVPN directly from the terminal. This document serves as an extensive guide to the NordVPN Linux CLI, detailing its commands, options, flags, and functionalities. The information is compiled from official NordVPN documentation and related resources, aiming to provide a thorough reference for both novice and advanced users.

The CLI enables users to select server locations, or allow the application to automatically choose the optimal server. It also offers customization of connection parameters, such as protocol selection (e.g., NordLynx, OpenVPN) and security features like the Kill Switch. The application interacts with several system components, including network interfaces via tuntap, firewall rules via iptables, routing via iproute2, and DNS
