   • The script displays a list of available OpenVPN configuration files (.ovpn) in the /etc/openvpn/client/ directory.

2. Creation of the systemd Service for OpenVPN:

   • Based on the configuration file selected by the user, the script automatically creates a systemd service file, allowing the OpenVPN connection to be managed as a standard system service.

3. Starting the OpenVPN Service:

   • The script offers the user the option to immediately start the newly configured OpenVPN service.

4. Enabling Automatic Startup:

   • The script also allows the user to enable the OpenVPN service to start automatically at system boot.

Usage

• Execution: The script should be run with administrative privileges to create and manage systemd services.
• Interaction: The script is interactive, prompting the user to choose a configuration file, start the service, and enable or disable automatic VPN startup.

Uninstall script

Key Features

1. List Available ovpn@ Services:

   • The script displays a list of configured OpenVPN services on the system, allowing users to quickly see which services are active.

2. Remove ovpn@ Services:

   • Users can choose to remove a specific OpenVPN service. The script automatically handles stopping, disabling, and removing the selected service.

Usage

DNS and IP leaks test

Script Name

checkleaks.sh

Description

This Bash script is designed to test VPN and Tor leaks on a Linux system. It checks the network configuration for potential DNS and IPv6 leaks, and can also display and compare the current public IP address.

Key Features

1. DNS Leak Check:

   • The script tests for DNS leaks using the dnsleaktest.com service, ensuring that DNS requests are not leaking outside of the VPN or Tor tunnel.

2. IPv6 Connectivity Check:

   • The script checks for IPv6 connectivity to ensure it is properly disabled, reducing the risk of IPv6 leaks.

3. Display and Store Public IP Address:

   • The script can display the user's current public IP address and store it for future comparison, helping to detect IP address changes.

4. Compare Current IP with Previous:

   • The script compares the current public IP address with a previously stored one to determine if the IP address has changed, which is useful for checking the effectiveness of the VPN or Tor network.

5. Command Options:

   • check: Runs DNS leak and IPv6 connectivity tests.
   • ip: Displays the current public IP address and stores it for future comparisons.
   • help: Displays a help message with available options.

Usage

• Execution: The script can be executed with one of the available options (check, ip, help). It guides the user through network security checks.
• Interaction: The script provides real-time feedback, color-coded for better readability, on the results of the tests performed.
