This tutorial will guide you through the process of installing IconCaptcha on NetBSD, a free and open-source operating system. IconCaptcha is a security measure that uses icons instead of traditional text to prevent bots and automated scripts from submitting forms on your website.
Before getting started, make sure you have the following installed on your system:
You will also need to have administrative access to your server to complete the installation process.
The first step is to clone the IconCaptcha repository from GitHub. To do this, navigate to a directory of your choice and run the following command in your terminal:
git clone https://github.com/fabianwennink/IconCaptcha.git
This will download the latest version of IconCaptcha to your local machine.
Once you have cloned the repository, you need to move the files to the appropriate folder on your web server. For example, if you are using Apache on NetBSD, you would typically move the files to the /usr/pkg/www/apache24/data directory.
To do this, navigate to the directory where IconCaptcha was cloned and run the following command:
sudo mv ./* /usr/pkg/www/apache24/data/
This command will move all the files from the cloned repository to the Apache data directory. If you are using a different web server software or a different directory, adjust the command accordingly.
IconCaptcha relies on a MySQL or MariaDB database to store configuration details and user data. Before you can start using IconCaptcha, you need to configure your database.
To do this, create a new database and a new user with full privileges. For example, you can use the following MySQL commands:
CREATE DATABASE iconcaptcha;
CREATE USER 'iconcaptchauser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON iconcaptcha.* TO 'iconcaptchauser'@'localhost';
Replace iconcaptchauser and password with your chosen username and password.
Next, open the config.inc.php file located in the includes directory of the IconCaptcha installation:
sudo nano /usr/pkg/www/apache24/data/includes/config.inc.php
Change the following variables to match your database configuration:
define('DB_HOST', 'localhost');
define('DB_NAME', 'iconcaptcha');
define('DB_USER', 'iconcaptchauser');
define('DB_PASSWORD', 'password');
Save and close the file.
Now that IconCaptcha is installed and configured, you can add it to your website. To do this, open the file where you want to add the captcha and include the following lines at the top:
require_once('includes/config.inc.php');
require_once('classes/iconcaptchaclass.php');
Next, add the following code wherever you want the captcha to appear:
$captcha = new IconCaptcha();
$captcha->display();
Save and upload the file to your web server.
You can now test IconCaptcha by visiting the page where you added the captcha. If everything is set up correctly, you should see a grid of icons displayed. To confirm that the captcha is working, try to submit the form without selecting the correct icons. You should receive an error message indicating that the captcha was not completed correctly.
Congratulations, you have successfully installed IconCaptcha on NetBSD! You can customize the captcha further by modifying the config.inc.php file or the CSS styles in the css directory of the IconCaptcha installation.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
