# Host PC Setup

A host PC running **native Ubuntu** requires no special setup - SSH is available out of the box, and USB Ethernet is configured automatically when DCS2 is connected.

All you need is a terminal and an SSH client. If SSH is not already available:

```bash
sudo apt update && sudo apt install -y openssh-client
```

{% hint style="info" %}
**Windows / macOS users:** SSH is available natively in Windows 10+ (PowerShell or Windows Terminal) and macOS Terminal. USB Ethernet may require additional driver or network configuration, depending on your OS. A native Ubuntu installation on the host PC is recommended for the smoothest experience, and is required for flashing with `dcs-deploy`.
{% endhint %}

### USB Ethernet - if not auto-configured

On most Ubuntu systems, the interface comes up automatically. If SSH is not reachable after connecting the USB cable, check whether the interface has been assigned an IP address:

```bash
ip addr show
```

If the interface appears but has no address in the `192.168.55.x` range, assign one manually:

```bash
sudo ip addr add 192.168.55.100/24 dev <interface_name>
sudo ip link set <interface_name> up
```

Replace `<interface_name>` with the actual interface name (e.g. `enx...` or `usb0`).

### Install dcs-deploy *(only needed for flashing)*

If you plan to flash a new system image, clone the tool from GitHub:

```bash
git clone https://github.com/airvolute/dcs-deploy
cd dcs-deploy
```

Refer to the [dcs-deploy README](https://github.com/airvolute/dcs-deploy) for full installation instructions and dependencies.
