Greetings, fellow Linux enthusiasts! As we all know, Linux Mint 20 Xfce is a popular operating system among tech-savvy users who prefer open-source software. One of the essential tools for online privacy and security is a proxy server. In this article, we will delve into the world of proxy servers and learn how to use them on Linux Mint 20 Xfce. So, let’s get started!
What is a Proxy Server?
A proxy server acts as an intermediary between a device and the internet. It receives requests from the device and sends them to the internet on the device’s behalf. The server can also receive responses from the internet and send them back to the device. In other words, a proxy server hides the device’s IP address from the internet, making it difficult to track the user’s online activities.
Proxy servers are commonly used in corporate environments to filter internet traffic, block unwanted websites, and monitor employee’s internet usage. They are also popular among individuals who want to access geo-restricted content, bypass internet censorship, or improve their online privacy and security.
There are several types of proxy servers available, including HTTP, HTTPS, SOCKS, and FTP. Each type has its own unique features and capabilities.
HTTP Proxy
An HTTP proxy server is a gateway that manages HTTP requests and responses. It can cache web content to improve performance, block malicious content, and filter web traffic based on rules. HTTP proxies are commonly used in web browsers and web applications.
HTTPS Proxy
An HTTPS proxy is similar to an HTTP proxy but encrypted with SSL or TLS. It adds an extra layer of security to internet traffic, making it difficult for hackers and cybercriminals to intercept sensitive data. HTTPS proxies are commonly used for online banking, shopping, and other activities that require secure communication.
SOCKS Proxy
A SOCKS proxy is a network proxy protocol that supports TCP and UDP traffic. It can handle any type of internet traffic, including web browsing, file transfer, and online gaming. SOCKS proxies are commonly used in peer-to-peer applications and virtual private networks (VPNs).
FTP Proxy
An FTP proxy is a gateway that manages FTP requests and responses. It can filter FTP traffic based on rules, block malicious content, and improve performance by caching FTP content. FTP proxies are commonly used in file transfer applications.
Why Use a Proxy Server on Linux Mint 20 Xfce?
There are several reasons why you might want to use a proxy server on Linux Mint 20 Xfce:
- Improved Online Privacy: A proxy server can hide your IP address from the internet, making it difficult to track your online activities. It can also encrypt your internet traffic, making it difficult for hackers and cybercriminals to intercept sensitive data.
- Bypass Internet Censorship: Some countries and organizations block access to certain websites and online services. A proxy server can bypass these restrictions by routing your internet traffic through a server located in another country.
- Access Geo-Restricted Content: Some websites and online services restrict access to users from certain countries. A proxy server can bypass these restrictions by routing your internet traffic through a server located in the allowed country.
- Improve Online Security: A proxy server can filter web traffic based on rules, block malicious content, and improve performance by caching web content.
How to Use a Proxy Server on Linux Mint 20 Xfce?
Now that we know the importance of proxy servers on Linux Mint 20 Xfce let’s learn how to set up and use them. There are several ways to use a proxy server on Linux Mint 20 Xfce:
1. System-Wide Proxy Settings
The easiest way to use a proxy server on Linux Mint 20 Xfce is to configure the system-wide proxy settings. This will apply the same proxy settings to all the applications that use the network. Here’s how to do it:
- Open the “Whisker Menu” and search for “Network Connections”.

- In the “Network Connections” window, select the “Wired” or “Wireless” tab, depending on which interface you use to connect to the internet.
- Select your network interface and click the “Edit” button.
- In the “Editing connection_name” window, select the “IPv4 Settings” or “IPv6 Settings” tab, depending on which version of the IP protocol you use.
- Under the “Method” dropdown menu, select “Manual”.
- In the “Manual” section, enter your proxy server’s IP address and port number in the “HTTP Proxy” and “HTTPS Proxy” fields.
- Click the “Apply” button to save the changes.
Now, all the applications that use the network will use the proxy server’s settings. You can also configure the proxy server settings for individual applications manually.
2. Command Line Tools
If you prefer to use the command line interface (CLI) to set up and use a proxy server on Linux Mint 20 Xfce, there are several command line tools available. Some of the popular command line tools for using a proxy server on Linux Mint 20 Xfce are:
- wget: A command line tool for downloading files from the internet. You can use the “–proxy” option to specify the proxy server’s settings.
- curl: A command line tool for transferring data from or to a server. You can use the “–proxy” option to specify the proxy server’s settings.
- apt-get: A command line tool for managing packages on Debian-based Linux distributions. You can use the “Acquire::http::proxy” and “Acquire::https::proxy” options to specify the proxy server’s settings.
3. Browser Settings
If you want to use a proxy server only for browsing the web, you can configure your browser’s proxy settings. Here’s how to do it in Firefox:
- Open Firefox and click on the “menu” button (three horizontal lines) in the top-right corner of the window.
- Select the “Preferences” option, and the “Preferences” window will appear.
- In the “Preferences” window, select the “General” tab.
- Scroll down to the “Network Proxy” section and click on the “Settings…” button.
