NVIDIA Sync on DGX Spark: Headless SSH Access from Windows

Published 24/05/2026

Description

In this video, I show how to connect to an NVIDIA DGX Spark in a headless way using NVIDIA Sync, SSH, and mDNS from a Windows machine. If you want remote terminal access, VS Code remote development, SSH key-based login, or access to the DGX dashboard without using a full remote desktop session, this walkthrough covers the setup step by step.

I also demonstrate different connection methods, including hostname, local DNS, mDNS, and IPv4, so you can choose the approach that best fits your environment. On top of that, I explain how NVIDIA Sync integrates with VS Code Remote SSH, how the DGX dashboard is exposed through SSH tunneling, and how to reuse the generated SSH keys with PuTTY. If you are working with DGX Spark, Ubuntu-based NVIDIA systems, Windows administration, or remote AI development workflows, this video will help you understand the practical options available. What you’ll learn in this video: NVIDIA Sync installation on Windows Headless access to NVIDIA DGX Spark SSH setup and key-based authentication mDNS hostname discovery on a local network VS Code Remote SSH integration DGX dashboard access through SSH tunneling Using PuTTY with NVIDIA Sync-generated keys Local DNS vs mDNS vs direct IP connectivity When to use NVIDIA Sync vs RDP/MSTSC Optional remote access scenarios with Tailscale If this helped you, don’t forget to like, subscribe, and leave a comment with your setup or questions. #NVIDIASync #DGXSpark #SSH Follow me on X: https://l.samayas.eu/jo3eaYEf3E?P=YT&V=129 Buy me a Coffee : https://l.samayas.eu/jX6xL7EWhd?P=YT&V=129 Studio Equipment Came
