Get a new NixOS machine online as a server: hostname, user, SSH, and key-based login.
## 0. Installer choice
You can't always assume the machine has an Ethernet port (e.g. some laptops, thin clients). The **minimal** ISO has no GUI and WiFi on the live system is fiddly (wpa_supplicant, dhcpcd, no NetworkManager). For machines without Ethernet, prefer the **graphical** NixOS installer: it includes NetworkManager and a desktop, so you can join WiFi in the GUI, then open a terminal and follow the same config steps below. Download the graphical ISO from the same NixOS channel (e.g. `nixos-graphical-*-x86_64-linux.iso` instead of `nixos-minimal-*`).
## 1. Prerequisites
- NixOS installed
- Machine on the network
- NixOS installed (minimal or graphical ISO)
- Machine on the network (Ethernet or WiFi)
- Console or existing SSH access
## 2. Hostname
