4nonimizer – A Bash Script For Anonymizing The Public IP Used To Browsing Internet

4nonimizer is a bash script for anonymizing the public IP used to browsing Internet, managing the connection to TOR network and to different VPNs providers (OpenVPN), whether free or paid. By default, it includes several pre-configured VPN connections to different peers (.ovpn files) and download the credentials (if the corresponding provider support it). Also, it records each used IP that we use every 300 seconds in log files.

This script is enabled as a service in systemd systems and uses a default vpn (VPNBook) at system startup.

Since version 1.06 the dns resolution requests are done throught DnsCrypt (enable and disable with option enable_dns or disable_dns)

Since version 1.12 the logs of connections vpn saved in sqlite in /logs/

4nonimizer Installation

Download the repo using git, execute the command ./4nonimizer install in the directory, and follow the screen instructions, 4nonimizer will move to the directory /opt/ and installed as a service.

This script has full compatibility with Kali Linux, although it has been properly tested and should also work on other distributions like Debian, Ubuntu and Arch (Manjaro). However there could be some bugs, or unexpected performances (please comments if you find any!).

Available VPNs

Currently it supports the following VPN providers:

Install A New VPN

To install an additional vpn we have to use the following structure in order to the 4nonimizer be able to integrate and perform operations with it.

First, we have to create the following dir structure /vpn/ within 4nonimizer path:

In our example we create the folder /vpntest/ and within it placed all .ovpn files we have. If the files ovpn not have the certificate within each of them we put in the same folder as shown in the example certificate.crt.

In addition, we must place a file named pass.txt containing 2 lines: the first one with the username and the second one with the password, as shown below:

If we have correctly performed all steps when we execute the command 4nonimizer change_provider the menu will show our vpn:

As you can see in the picture, option [7] it is the vpn we’ve created.

Getting Credencials & ovpn Files Automatically

If the VPN provider allows automation of credential and/or .ovpn files getting, 4nonimizer has standardized the following scripts names and locations:

– /opt/4nonimizer/vpn/provider/vpn-get-pass.sh

– /opt/4nonimizer/vpn/provider/vpn-get-ovpn.sh

4nonimizer automatically detect the presence of both scripts and indicate (Auto-pass Login) or (Auto-get OVPN) if it finds in the first line of each file the expression ‘#4uto’ or ‘#m4nual’ depending on the performed actions.

Additional

– Execute ‘source 4nonimizer’ to activate autocompletation of parameters.
– Copy .conkyrc in your home directory to load a 4nonimizer template and execute conky.
