IconCaptcha is an innovative and user-friendly security tool for websites that uses icons instead of traditional text to verify human users. In this tutorial, we will walk you through the process of installing IconCaptcha on Fedora Server Latest.
Before you can install IconCaptcha on your Fedora server, you will need the following:
The first step is to install the required packages on your Fedora server. Run the following command to update your server's package list and install the packages:
sudo dnf update
sudo dnf install httpd php
You will also need to install the PHP-GD library for image processing:
sudo dnf install php-gd
Next, download the latest version of IconCaptcha from the official website. You can use the following command to download the file:
sudo wget https://www.fabianwennink.nl/projects/IconCaptcha/IconCaptcha_latest.zip
Extract the downloaded file using the following command:
sudo unzip IconCaptcha_latest.zip -d /var/www/html/
This will extract the files to the default Apache web root directory.
Next, you need to modify the file permissions for the IconCaptcha directory. Run the following command to give the Apache user read and write permissions:
sudo chown -R apache:apache /var/www/html/IconCaptcha
sudo chmod -R 755 /var/www/html/IconCaptcha
Open the configuration file for IconCaptcha in your preferred text editor:
sudo nano /var/www/html/IconCaptcha/inc/config.inc.php
In this file, you can configure different settings for IconCaptcha.
Make sure to change the default values for IC_SALT and IC_DB_PASSWORD to your own values:
define("IC_SALT", "<RANDOM STRING>");
define("IC_DB_HOST", "localhost");
define("IC_DB_NAME", "IconCaptcha");
define("IC_DB_USER", "root");
define("IC_DB_PASSWORD", "<YOUR PASSWORD>");
After completing the configuration, restart the Apache web server with the following command:
sudo systemctl restart httpd
To test IconCaptcha, go to your website's login page and complete the login process. If everything was configured correctly, you will see the IconCaptcha widget on the login page.
Once IconCaptcha is installed and tested successfully, you can integrate it into your website or application. To do this, you will need to include the IconCaptcha PHP file in your login form, and use the function ic_check_captcha() to verify the user's input.
require_once('/path/to/IconCaptcha/inc/captcha.inc.php');
$valid = ic_check_captcha($_POST['captcha_value']);
IconCaptcha is a useful and user-friendly tool for securing your website against automated attacks. By following this tutorial, you should now have a working installation of IconCaptcha on your Fedora Server Latest. You can now integrate it into your website to verify human users and improve your website's security.
