How to Configure Squid Proxy Server for Anonymous Browsing

How to Configure Squid Proxy Server for Anonymous Browsing

In web browsing, privacy and security are major concerns. Everyone want to ensure that their data and browsing habits are hidden from prying eyes. One way to achieve this is through anonymous browsing. This is where a Squid Proxy Server comes in handy. Squid is a caching and forwarding HTTP web proxy that has extensive access controls and makes a great server accelerator. It runs on most available operating systems including Windows and is licensed under the GNU GPL.

In this tutorial, we will walk you through the process of configuring a Squid Proxy to allow for anonymous browsing. This can help protect your privacy by hiding your IP address and allowing you to surf the web without leaving a digital footprint.

Before we start, it’s important to note that while Squid can provide a level of anonymity, it’s not a complete solution for privacy. For more comprehensive privacy protection, consider using additional measures such as VPNs or Tor.

This tutorial assumes you have Squid installed on your CentOS server. If not, you can refer to our guide on How to Install Squid on CentOS.

Step 1: Backup Your Current Squid Configuration

Before making any changes, it’s always a good idea to backup your current configuration. This allows you to revert back to the original settings if something goes wrong. You can do this by copying the squid.conf file to a backup file:

cp /etc/squid/squid.conf /etc/squid/squid.conf.backup

Step 2: Edit the Squid Configuration File

The main configuration file for Squid is located at /etc/squid/squid.conf. Open this file in a text editor:

nano /etc/squid/squid.conf

Step 3: Enable Anonymous Browsing

To enable anonymous browsing, you need to add or modify certain directives in the Squid configuration file.

First, locate the following line:

http_port 3128

Replace it with:

http_port 3128 intercept

This tells Squid to intercept all HTTP traffic on port 3128.

Next, locate the following lines:

visible_hostname localhost

This line can be left as is, or you can change “localhost” to your server’s hostname.

Finally, add the following lines to the bottom of the squid.conf file:

via off
forwarded_for off
request_header_access Allow allow all
request_header_access Authorization allow all
request_header_access WWW-Authenticate allow all
request_header_access Proxy-Authorization allow all
request_header_access Proxy-Authenticate allow all
request_header_access Cache-Control allow all
request_header_access Content-Encoding allow all
request_header_access Content-Length allow all
request_header_access Content-Type allow all
request_header_access Date allow all
request_header_access Expires allow all
request_header_access Host allow all
request_header_access If-Modified-Since allow all
request_header_access Last-Modified allow all
request_header_access Location allow all
request_header_access Pragma allow all
request_header_access Accept allow all
request_header_access Accept-Charset allow all
request_header_access Accept-Encoding allow all
request_header_access Accept-Language allow all
request_header_access Content-Language allow all
request_header_access Mime-Version allow all
request_header_access Retry-After allow all
request_header_access Title allow all
request_header_access Connection allow all
request_header_access Proxy-Connection allow all
request_header_access User-Agent allow all
request_header_access All deny all

This will strip out all other headers in the HTTP request, making your browsing more anonymous.

Step 4: Save and Close the Configuration File

After making these changes, save and close the squid.conf file. If you’re using nano, you can do this by pressing Ctrl+X, then Y, then Enter.

Step 5: Restart Squid

For the changes to take effect, you need to restart Squid. You can do this with the following command:

systemctl restart squid

Step 6: Test Your Configuration

To test your configuration, you can use a web browser or a tool like curl to make a request through your proxy server. The request should be anonymous, with no identifying information.

Commands Mentioned:

  • cp /etc/squid/squid.conf /etc/squid/squid.conf.backup – Creates a backup of the current Squid configuration.
  • nano /etc/squid/squid.conf – Opens the Squid configuration file in a text editor.
  • systemctl restart squid – Restarts the Squid service, applying any changes made to the configuration.

Conclusion

This will help protect your privacy by hiding your IP address and allowing you to surf the web without leaving a digital footprint.
