- modules/remote.nix: OpenSSH with keys only (no passwords, no root), ports 22 and 8080 (zvm_node) opened for 192.168.1.0/24 only; /etc/hosts names for both machines (DNS goes over TLS, so the router's *.lan names don't resolve) - the laptop accepts the PC's key; the PC's list is ready for the laptop's - hostName: nixos -> nexo-laptop Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
