### Requirements

Before getting started, ensure that:

* No other VPN or proxies are active.
* You have your GoProxies endpoint ready, e.g. `proxy.goproxies.com:1080`
* Your GoProxies subuser (also called API User) username and password.

### Proxy Setup

1. Open **Terminal**.
2. Sign in as a root user.
3. Open the `/etc/environment` file with `nano`.
4. In the text editor, configure your proxy as follows:

```
http_proxy="http://proxy.goproxies.com:1080"
https_proxy="http://proxy.goproxies.com:1080"
no_proxy="localhost"
```

{% hint style="info" %}
If you need authentication, use the format `http://username:password@proxy.goproxies.com:1080`. You can also target a specific country by appending `-country-country_abbreviation` to your username, e.g. `customer-exampleuser-country-us`, as covered in our [proxy parameters article](https://docs.goproxies.com/proxies/rotating-residential-proxies/proxy-parameters).
{% endhint %}

5. Press `CTRL + X`, then `Y` to save, and `ENTER` to confirm the file location.
6. Lock the file with `chattr +i /etc/environment` and reboot your machine. Skipping this step may cause your proxy settings to reset.

{% hint style="info" %}
To unlock the file later, use `chattr -i /etc/environment`.
{% endhint %}

### Verify the Connection

Open a browser and go to [ip.goproxies.com](https://ip.goproxies.com). If the IP shown reflects your proxy location, you're all set.
