There are multiple ways to set up a proxy server for Ubuntu. In this guide, you'll find two common methods: [using System (GNOME) settings](#method-1-system-settings) and [utilizing the terminal](#method-2-terminal-sessions). ### Method 1: System settings To set up a system-wide network proxy, follow the steps below: **Step 1.** [**Download**](https://ubuntu.com/download/desktop) and install Ubuntu Desktop. **Step 2.** Find **Settings** from the Ubuntu launcher and go to the **Network** tab.
Network
**Step 3.** Once you click on **Network**, it will open up a new dialog. From the three options, choose **Network Proxy.**
Network
**Step 4.** Select **Manual** to configure proxy settings. Next, several text boxes will pop up from which you can set `HTTP`, `HTTPS`, `FTP` & `SOCKS` proxy. Fill in the following information: **HTTP Proxy**: `isp.oxylabs.io` **Port**: `8001` {% hint style="info" %} You will need to choose the port assigned to an IP address from the purchased [**proxy list**](https://developers.oxylabs.io/proxies/isp-proxies/proxy-list)**,** which you can find on Oxylabs' dashboard. The `8001` port will pick the first IP address from your list for all requests. {% endhint %}
**Step 5.** Close the Network Proxy window. The changes will automatically be saved, and the system-wide proxy will be activated. Each time you make a web request through a browser or other application, a **pop-up window will prompt you to enter the credentials** of your Oxylabs proxy user for the session. {% hint style="warning" %} Remember to append the `user-` part to your username, for example: `user-USERNAME`. {% endhint %} *** ### Method 2: Terminal sessions To set up a network proxy for all terminal sessions, follow the steps below: **Step 1.** [**Download**](https://ubuntu.com/download/desktop) and install Ubuntu Desktop. **Step 2.** Open **shell** configuration using an editor. For the ZSH terminal, the shell configuration file is by default located in the home directory. We can edit this file using `vim` with the below command: ```sh vim ~/.zshrc ``` Instead of `vim`, you can also use `gedit`, `nano`, or any other text editor that you prefer. Also, if you are using Bash instead of ZSH, you’ll have to edit your bash shell configuration file, i.e. `~/.bashrc` instead of `~/.zshrc`. **Step 3.** Create two new environment variables At the bottom of this configuration file, you’ll have to define the `http_proxy,` `https_proxy`, or `ALL_PROXY` (for SOCKS5) variables. ```sh export http_proxy="user-USERNAME:PASSWORD@isp.oxylabs.io:8001" export https_proxy="user-USERNAME:PASSWORD@isp.oxylabs.io:8001" export ALL_PROXY="socks5://user-USERNAME:PASSWORD@isp.oxylabs.io:8001" ``` Here are the details you need to fill in: **Proxy address:** `isp.oxylabs.io` **Port:** `8001` {% hint style="info" %} You will need to choose the port assigned to an IP address from the purchased [**proxy list**](https://developers.oxylabs.io/proxies/isp-proxies/proxy-list)**,** which you can find on Oxylabs' dashboard. The `8001` port will pick the first IP address from your list for all requests. {% endhint %} **Username:** `user-username` **Password:** `password` {% hint style="warning" %} Don't forget to add the `user-` part to your username. {% endhint %} **Step 4.** Reload the configuration Now, you can reload the configuration file either by opening a new terminal or by running the following command in the existing terminal: ```sh source ~/.zshrc ``` The proxy will always be active for the current user. The shell configuration file gets loaded every time you open a new terminal. So, the environment variables will be always available for you even if you restart your computer. If you want to enable it for all users then you will have to append the above two lines in the `/etc/environment`. That’s all! You’ve successfully integrated your Oxylabs proxies.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://developers.oxylabs.io/integrations/proxy-integrations/isp-proxies-guides/ubuntu.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
