WARNING

May contain out of date information. Check the comments below!

The list of actions listed below was taken mostly from Book Of Zeus with minor modifications and did the job well for Ubuntu version, which was available at that moment (May 2016). This gist was created for internal use and was never meant to be discovered by the web, although Google managed to find and index this page, which was a great surprise for me. Please check the original source for the updated information (links are provided in most of the sections), and read the comments below: they provide more details about the usage experience.

System Updates

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.

Build a Squid anonymous proxy from source code

Please note that this whole manual refers to the version 3.5.23 of Squid. You probably would have to adapt some commands to the version you will actually download.

Theory:

your git repository can have more than one remote server; In this case we want to have two:

1. one for our private repository on gitlab (will be the default one, called origin)
2. one to be connected to the source repo on github, to be able to pull new changes (will be called upstream)
