Episode #341: Introduction to Using Squid Web Proxy Server

Description:
In this class Eli the Computer Guy shows you why Web Proxy Servers are useful, and how to setup a new SQUID Proxy Server. He discusses the different uses of Web Proxy Servers, and demonstrates the basic steps to set one up, and have a Windows PC connect to it.

Notes:
Squid uses
Cache -- The SQUID Proxy Server can Cache web files from all eb Requests and then transefer those chaced files locally if another host requests the same file
ACL Control -- Access Control Lists allow you to specify whether certain websites can be accessed.
Bypass Web filters -- You can connect to a Proxy Server on a different network to bypass Web Filers on your LAN

Squid Configuration Setup on Server Setup (Note: These steps are shown using Ubuntu 12.04 Server Edition. The basic steps are the same on all Linux distributions, but the actual commands may be slightly different. Please just use Google to find the correct commands if these do not work for you.):
To Install SQUID: sudo apt-get install squid
To Allow Access to the SQUID Server from Hosts Change: http_access deny all --http_access allow all
Restart SQUID Service after any configuration changes: service squid3 restart

To Configure Internet Explorer (Note: Proxy Server Configurations are set within Internet Explorer for the Entire System. Even if you use Chrome you still need to change the settings in IE) :
Open Internet Explorer and Go to Tools
Select Internet Options
Select Connections Tab
Click LAN Settings Button
Select Checkbox under Proxy Server Settings and enter the Proxy Servers IP Address, and the port number SQUID is using. (The port number default is 3128)
Click OK

Thanks Eli, I been using linux for years and was always interesting in setting up a proxy server. BUT in all my studies no author ever revealed the simple advantages of a proxy server, until I listened to your video. Now you have created a hunger in me. And when a tech person hunger arises, their is nothing that will stop us from learning. Thanks so much, man.

Thank you so much Eli!! This is without a doubt the best resource I have found on Squid. I have been fighting with the slippery bastard for three days with no results. After watching this video I can now connect to my computer located in the US.

Just wanted to take this time to thank you for Episode # 341, I have a better understanding on how Proxy Server work. You are the man....

[machinemaker]

Finally! Thank you, Eli. Everyone else just gives a list of steps to follow with no explanation why or what they're doing. Useless! You are an excellent teacher.

Where's part 2?

[SisiraSomaratne]

Your lesson is very organized and clear. I watched many videos in this topic and finally this is the one I could understand. That because you first explained it on the whiteboard and later went to the computer. Thank you

It's auto setup to cache files up to 4MB in size. So it will make web browsing in general faster, but will not cahce large files by default.

Eli, I really enjoy your videos. At school, as I learn the concepts, I come watch your videos to further understand the concepts that I learn.  They expand my learning curb and keep up the good work dude.

9 years old video but still very usefull and helpfull :)

[tulaykurt]

haha the best part is the 'siistt' sound when the dog barked :D hahahaha

[elithecomputerguy]

Technically the router is probably faster, but with Caching the Proxy will seem faster... You definitly gain more control with a Proxy. You can create some insane rules using ACL's within SQUID...

[tradford]

Just Awesome Eli!! Missed the more in depth tech stuff for the last couple days. This is excellent!!

[superspectator]

I am checking your channel every day to see if you have made more videos on squid. Highly interesting topic.

[commonman]

You Sir? ARE FREAKING AMAZING!!!
Just thought I'd let you know that...
Cool?
Cool...

[cyber_dev]

This is what I call a masterpiece lecture, , , , Great Job man....

[alreid]

Awesome vid as always Eli.
Looking forward for more in depth on squid and hope you discuss how to prevent users from bypassing the proxy and if there is a way to use without modifying the browser proxy settings.
Thanks you again for taking time to make great videos.

[jensyfrenzy]

This is one of the most informative videos I have ever seen on proxy servers. Thank you for sharing!

[ModellazioneTreD]

Come al solito a ogni video c'è da rimanere a bocca aperta!!!
Approfitto per invitarvi tutti al mio canale ^_^ son nuovo del tubo
