Squid is a popular open-source web proxy that can be used to hide a system's real IP address by forwarding requests through a different IP address. This can be useful for anonymous browsing or to bypass network restrictions.
To hide a system's real IP address using Squid, you will need to follow these steps:
Install and configure Squid on the system you want to use as a proxy. You can find detailed instructions for installing and configuring Squid in the official documentation: https://wiki.squid-cache.org/SquidFaq/Installation
Edit the Squid configuration file ("/etc/squid/squid.conf") and add the following lines to enable forwarding through a different IP address:
forwarded_for off
via off
Restart Squid to apply the changes.
Configure your client to use the Squid proxy. This can be done by setting the "http_proxy" environment variable or by configuring a web browser to use the proxy.
It's worth noting that hiding a system's real IP address may not provide complete anonymity, as other information such as the browser and operating system can still be identified. You may also need to configure additional measures, such as using a VPN or Tor, to achieve a higher level of anonymity.
