Once the installation is completed, the proxy will start automatically. Just run the standard commands to proceed with its installation: $ sudo apt update The Squid package is included in the standard Debian 10 repositories. In this tutorial you will see how to set up Squid Proxy on a Debian Buster server and how to configure some web browsers to be able to use this proxy. This proxy can improve the performance and security of your web server by saving requests already made in a cache memory, filtering web traffic and restricting access based on geolocation.
To begin, to install Squid on Debian-based Linux distributions, run the command below.Squid is a caching proxy that supports various network protocols such as HTTP, HTTPS and FTP. Getting started with Squid proxy in Linux: Usually, several cache servers are implemented, and they are structured as trees. In this case, only new or modified data will load the rest will remain stored in the server. All connection petitions requested by local network devices are passed through the internal network card and forwarded to the external network card if traffic is allowed.Īdditionally, Squid proxy works as a cache server by saving data obtained from different petitions, increasing the traffic speed when similar petitions are done. A network card is used for the local network, while the second is used to access the internet. Usually, in this scenario, the proxy device has two network interfaces. Using a proxy, network administrators can blacklist forbidden websites or applications although this is not Squid’s main purpose, it is useful to increase network activity control. Since all connections pass through the proxy, its implementation allows us to filter accesses. Only the device working as a proxy needs internet access the rest of the devices will connect through it. In this tutorial, we will redirect local network traffic to the internet through the Squid proxy. In other words, a proxy server function is to concentrate the network traffic through a single server. What is Squid proxy:Ī proxy is a server located between two networks in this case, the most common implementation of a Squid proxy is the division between user computers and devices and the internet, divided or separated by a proxy server in the middle. This tutorial explains how to configure Squid proxy in Linux.Īfter reading this tutorial, you will know how to configure Squid port and hostname, block access to specific websites, and allow internet access to specific devices.
