Our take

Based on the ratings of 287 students, a sample of their written reviews and the syllabus, as the course stood in July 2018. No course pays to be reviewed.

This is a short, practical course on Squid, the open source proxy server used for web gateways, anonymizing traffic, and reverse proxying on Linux. Built by The Startup Central Co. with Jasenko Kreji, it runs 2.9 hours across 36 lectures and walks through installing prerequisites, building access control lists, and reading log files on a CentOS virtual machine. The stated level is all levels, but the real audience is IT admins and network engineers who already run Linux day to day.

Reviewers respond well to the extras: some call out the instructor's clear delivery and the side notes on iptables, vi, and bashrc that help newcomers get oriented. The rating breakdown skews high, 137 five-star and 97 four-star out of 287, and one reviewer says it is the only Squid course they could find on other learning platforms. The complaints are consistent though: the course leans on CentOS 6, and reviewers in 2021 through 2024 report the repos and service commands no longer match current CentOS or RHEL, forcing some googling to get past setup. A few also say it stays basic and skips caching and detailed auth topics.

At under three hours it will not eat your weekend, and the exercises make the ACL sections stick. But the 2018 last update is showing, and if you are on a recent Linux release expect some friction translating the steps. Reviewers still rate it useful for someone starting from zero on Squid, just budget extra time for troubleshooting the OS setup that the course itself no longer covers.

Best forIT admins or Linux users who need to stand up a working Squid proxy fast, with exercises.
Skip it ifYou want caching, SquidGuard filtering, or a course updated for recent CentOS/RHEL releases.

Pros

  • Clear, real-world explanations reviewers single out by name
  • Hands-on exercises tied to each ACL and config section
  • Covers gateway, anonymizing, and reverse proxy use cases in one course
  • Extra tips on iptables, vi, and bashrc help total beginners

Cons

  • Built on CentOS 6, and reviewers report repo and command mismatches on newer CentOS/RHEL
  • Not updated since 2018, so some steps need extra troubleshooting
  • Skips caching and goes light on authentication and other advanced topics
It's a good and thorough course, but very out of date. It definitely needs to be updated as a lot has happened since 2018.
Jørn Tillnes, a student

Fits beginners to Squid specifically, but expects basic Linux and networking comfort already in place.

WHAT IS SQUID PROXY SERVER?

Squid is a 20 year old open source software mostly installed on UNIX-like systems such as Linux, and is used as proxy server.

It can be used as web gateway, for anonymizing a proxy server or even as a reverse proxy.

Squid experts are high in demand, because there are a lot of job opportunities for setting, maintaining or integrating Squid proxy servers.

Its commercial competitors are priced at tens of thousands of dollars, so there are a lot of money to save.

The course itself is 3 hours long, but you will probably need around six hours to finish it, since it contains quizzes and hands-on experiences.

The main problem I have is that now (230922) CentOS 6.9 is too old to be used (the repo's weren't available when I try to use yum), so I had to choose a different CentOS, 7.9 in my case, and there a lot of the setup of the OS didn't match, so I had a lot of struggle to get the operating system up and running before I could actually do the rest of the course. But so far the ACL stuff has been good, but it would be good with an update of the OS installation.

By Anonymized User on 7/17/2023

Awesome content! Thank you so much for your hard work on this. Your delivery of the content is great and I love the additional info you give (iptables, vi, bashrc, etc.). It will be a great help to newbies. :)

By David Vidal on 11/16/2022

He aprendido todo lo que necesitaba saber para instalar y manejar squid, ya que lo necesito para mi trabajo diario

By SUON Samnang on 2/23/2022

This course is a must-have because there is no Squid Server course on other learning platforms like Pluralsight, Linkedin Learning, etc. It is a small investment that will pays out (instead of wasting hours on YouTube)

By Anthony Guttadauro on 1/21/2021

Great Course, some of the lectures need a little bit more explanation for the technical jargon, but other than that it is still a very good course and still relevant, however, some of the service commands are out of date.

By Omari Rose on 1/9/2021

Good starter course of using and configuring a squid proxy application. Some of the material needs to be updated using more recent versions of Red hat/CentOS linux (7 and 8) with SystemV commands.

By Pedro Estrada on 5/12/2020

Thorough walk-throughs and exercises. I followed along on a newer version of CentOS and Squid, and still managed to get everything working with the supplied information!

By Julio Morales on 4/10/2020

This was a good course for beginners looking for an easy to use proxy server and want to get up and running as quickly as possible.

By Jesse Rosenbaum on 3/21/2020

The course material is very clear and explained well. I was able to get my instance of Squid Proxy Server up and running and use the lessons from this course to make it functional for my needs.

By David Rasmussen on 7/25/2018

Nicely structured course and the instructor is clear and precise. With the exercises it feels like I will remember the lessons better. How to toggle access for individual users seems rather straightforward using Squid, at least from this course. Good job.
