azos

Overview

NixOS-WSL instance running on a Windows machine on the local network.

Static IP: 192.168.1.200
GPU: NVIDIA RTX 3050, 6GB VRAM, CUDA 13.2
Config: _machines/beacon-wsl.nix → nixos/configuration-beacon-wsl.nix

SSH Access

Uses YubiKey GPG key (cardno:29_109_265) — same key as lauretta. Authorized key is set in users.users.aner.openssh.authorizedKeys.keys in the NixOS config. Password auth disabled; root login disabled.

Remote Deployment

Build locally and copy FAILS due to unsigned path rejection by remote Nix daemon. Must build on the target host itself:

nixos-rebuild switch \
  --flake '/home/aner/azos?submodules=1#beacon-wsl' \
  --target-host aner@192.168.1.200 \
  --build-host aner@192.168.1.200 \
  --elevate=sudo

CUDA / GPU

programs.nix-ld.enable = true required to run WSL-provided binaries (nvidia-smi, etc.)
nvidia-smi lives at /usr/lib/wsl/lib/nvidia-smi; needs LD_LIBRARY_PATH=/usr/lib/wsl/lib
hardware.graphics.enable = true exposes GPU via WSL2 paravirtualization
CUDA-enabled torch works via nix shell with config.cudaSupport = true (see roll project flake)

Windows-Side Setup

Mirrored networking: C:\Users\<user>\.wslconfig with [wsl2] networkingMode=mirrored
Windows Firewall inbound rule for TCP port 22 required (-Profile Any)
Static IP set via Windows network adapter settings
