How to Configure Proxy Settings in Ubuntu GUI & Terminal

Ubuntu is an open-source Linux distribution developed by Canonical. It’s a secure and robust operating system with over 10 years of security patching for various CVEs (Common Vulnerabilities and Exposures), making it an ideal Linux distribution for production and enterprise environments. Moreover, Ubuntu’s intuitive GUI (Graphical User Interface) makes it beginner friendly and widely popular among Linux users.

This tutorial will demonstrate how to set up Oxylabs Residential and Datacenter Proxies in Ubuntu. We’ll be using Ubuntu 20.04 LTS, but this integration method should also work on similar Linux distributions such as Debian, Xubuntu, etc.

How to set up a proxy in Ubuntu GUI

There are multiple ways to set up a proxy using Ubuntu’s GUI. The easiest one is using Settings > Networks > Network Proxy

In this method, we’ll be using Ubuntu Settings to set up a system-wide network proxy. Follow the steps below:

Step 1: From the Ubuntu launcher find Settings and go to the Network tab

The Ubuntu launcher is the dock available on desktop. By default, it’s located on the left side of the screen. From the launcher, click Show applications to toggle the search prompt. In there, type in Network.

Click on Settings > Network.

Step 2: Click on Network

Once you click on Network, it’ll open up a new dialog where you’ll find three options: Wired, VPN, and Network Proxy. Click on Network Proxy.

Step 3: Configure Proxy Settings

After you click on Network Proxy, a new window will appear that will contain three options: Automatic, Manual, and Disabled. By default, Disabled will be selected. To configure a proxy server click Manual. Next, several text boxes will pop up from which you’ll be able to set HTTP, HTTPS, FTP & SOCKS proxy.

Residential Proxies 

Let’s set up Oxylabs’ Residential Proxy. You need to put the server address pr.oxylabs.io in the HTTP proxy text box and set the port to 7777.

Note that it’s also possible to use country-specific entries. For instance, if you enter us-pr.oxylabs.io under IP address and 10000 under Port, you’ll acquire a US exit node. You can find the complete list of country-specific entry nodes and sticky session details in our documentation.

Dedicated Datacenter Proxies

If you want to set Dedicated Datacenter Proxies, you’ll have to use a specific datacenter IP as the server address. Set the port to 60000.

In the above screenshot, we’ve put an example IP address 192.168.1.100. You’ll have to replace it with your own dedicated datacenter IP address.

Shared Datacenter Proxies
For the Shared Datacenter Proxies, the server address is dc.pr.oxylabs.io and port 10000.

You can also use a country-specific entry. For instance, if you enter dc.de-pr.oxylabs.io under IP address and 40000 under Port, you’ll acquire a German exit node. Find a complete list of country-specific entry nodes in our documentation.

That’s it! Once you close the Network Proxy window, the changes will automatically be saved and the system-wide proxy will be activated. 

Now, time to learn how to set up a proxy from the terminal.

How to set up a proxy in Ubuntu terminal

There are multiple ways to set up a proxy in the Ubuntu terminal. Let’s begin with temporary proxy settings using proxy environment variables. 

Set up temporary proxy for the current terminal session

The temporary proxy will only be active for the current terminal session and will reset to default as soon as we close the terminal or end the terminal session.
First, open a new terminal. You can also use the shortcut “CTRL + ALT + T” which will open a new terminal for you. In the terminal, create two new environment variables using the below commands:

export http_proxy="username:password@pr.oxylabs.io:7777"
export https_proxy="username:password@pr.oxylabs.io:7777"

Make sure there are no spaces between the equal signs and variables. The export command sets new environment variables for the current terminal session. You can verify that the environment variables are active by running it. 

export

This will show all the environment variables including http_proxy and https_proxy that are active in the current session. The string username:password@pr.oxylabs.io:7777 has the format <username>:<password@<server_address>:<port>. Also, we are assuming the proxy username and password are the strings “username” and “password” respectively. You can replace this information with the appropriate one.

For the Shared and Dedicated Datacenter proxies only the server_address and port will change. The rest will remain the same. For example, for Shared Datacenter Proxies, add the following lines of code:

export http_proxy="username:password@dc.pr.oxylabs.io:10000"
export https_proxy="username:password@dc.pr.oxylabs.io:10000"

Once you export these environment variables, the proxy will be activated for all the subsequent commands. We can make sure the proxy is activated by running the below command and checking our IP address:

wget -qO- http://httpbin.org/ip

If you don’t have Wget installed on your computer then, you can also run it using cURL.

Permanently configure proxies for all terminal sessions

The downside of temporarily configuring proxy using environment variables is that you’ll have to do it every time you start a new terminal. You can avoid this redundant work by configuring a permanent proxy for all of your terminal sessions. Depending on which shell you are using we need to modify the shell configuration file. 

Step 1 - 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:

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 2 -  Create two new environment variables

At the bottom of this configuration file, you’ll have to define the http_proxy and https_proxy variables:

export http_proxy="username:password@pr.oxylabs.io:7777"
export https_proxy="username:password@pr.oxylabs.io:7777"

The pattern is exactly the same as the temporary proxy. Also, you can modify them for dedicated datacenter or shared datacenter proxies if you want to use those instead of a residential proxy.

Step 3 - Reload the configuration

Now, we can reload the configuration file either by opening a new terminal or by running the following command in the existing terminal:

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.

Set up proxy for APT from terminal

APT is the package manager for Debian, Ubuntu & Linux Mint, etc. It works through the use of repositories or special directories that hold collections of software packages that users can install using a simple command. To use a proxy for the APT package manager some additional work is necessary. We’ll have to edit the /etc/apt/apt.conf file. Go ahead, and open it using vim:

vim /etc/apt/apt.conf

Now, add the below lines to activate Oxylabs’ Residential Proxy for APT:

Acquire::http::Proxy "http://username:password@pr.oxylabs.io:7777";
Acquire::https::Proxy "http://username:password@pr.oxylabs.io1:7777";

The next time you install or update your existing applications or packages, APT will use the Oxylabs’ Residential Proxy. You can replace it with shared datacenter proxies or dedicated datacenter proxies, just like we did in the other methods. But don’t forget to set the proper server address and port number. Additionally, replace the username and password with the correct credentials. Otherwise, you will get a 407 Authentication Required Error.
