How to set up a proxy on Linux

Linux with configured proxies provides comprehensive and reliable protection of confidential data, ensuring guaranteed anonymity when surfing the Internet and effectively circumventing various geographical restrictions on access to content. By utilizing proxy servers at the operating system level, users gain enhanced capabilities for secure networking. Proxy servers provide system administrators, software developers and ordinary users with full and detailed control over network traffic, which allows to create the most secure and carefully controlled network environment with the ability to fine-tune security settings and monitor all network connections.

### What are the best proxies to use on Linux?

Linux fully supports HTTP(S)-proxies and SOCKS5 proxies, providing flexible configuration options both at the system level and for individual applications. Using customized IPv4 proxies or mobile proxies ensures a stable and secure connection.

### Installation and configuration

Setting up a proxy in Linux can be done in several ways, depending on your needs and the distribution you are using. There are two main methods: graphical and through the terminal. Let's take a look at both

**Use NetworkManager (GUI):**

- Open Network Settings.

**Use OpenVPN via Terminal:**

These steps will work for most Linux systems such as Ubuntu, Debian, Fedora and others.

On most Linux systems it is already installed and available to run, but if not it can be installed by typing the command in the terminal

**sudo apt install openvpn # For Debian/Ubuntu**

**sudo yum install openvpn # For CentOS/Fedora**

Download the configuration files from your ISP.
