Building a Web Developer / Designer PC

One of my earlier posts, Faster Internet With an Old Laptop – Ubuntu and Squid, discussed how to install Squid and Webmin on an old laptop. The premise being that having a proxy server on the network helped speed up web browsing (because of the caching capabilities), reduced external bandwidth usage, etc.

In that post, I was careful to install Squid3 first, so that Webmin would use it (in the management interface) instead of the older Squid 2.x; and that the installation would be smoother. One thing I noticed was that webmin was using an older version of squid:

"...I noticed that webmin (for some strange reason) thought squid 2.6 was installed..."

One of our readers (atass) provided a useful comment in that post:

"The reason is that you have also installed squid3 AND 2.6. 2.6 was installed via webmin because it is not configured by default to find squid3

I think you should correct this procedure so that you correctly configure webmin to use squid3 by going to module configuration and changing to squid3 paths. Avoid installing Squid via webmin cause it will install Squid 2.6 regardless if you have squid 3 installed"

So this needed fixing, here are the settings (below) I changed to get Squid3 going. Above all, remember to back up data or settings before changing anything.

Log into your webmin interface and select "Squid Proxy Server" from the left side navigation menu.
At the top select "Module Config".
Change the following values:

Full path to squid config file: /etc/squid3/squid.conf
Squid executable: squid3
Full path to squid cache directory: /var/spool/squid3
Full path to squid log directory: /var/log/squid3

Now remember to stop squid and start squid3, via ssh (substituting for your IP address instead of mine):

ssh root@192.168.1.200

sudo /etc/init.d/squid3 restart

sudo /etc/init.d/squid stop

Now try surfing with your web browser configured to use the Squid3 proxy. If you get an error message (like I did):

--------------------------------------------------------------------------

The requested URL could not be retrieved

While trying to retrieve the URL: http://ubuntulinuxhelp.com/

The following error was encountered:

* Access Denied. Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Your cache administrator is xxxx@xxxx.com.

--------------------------------------------------------------------------

Double check your Access Control in the "Squid Proxy Server", Select the padlock icon that says "Access Control".

Mirror the original settings you had in the Access Control for the older version of Squid. Then select the "Proxy Restrictions" tab, and again mirror the settings.

Then I restarted Squid3

sudo /etc/init.d/squid3 restart

And tried to surf the web... and everything works!

Big thanks to the reader that pointed out the issue. That's appreciated! :)
