Борьба с несанкционированным доступом к HTTP Auth Captive 8002 через блокировку

HTTP Captive Portal (auth) is a type of network authentication that requires users to authenticate or agree to terms and conditions before gaining access to a network.

Port 8002 is not a standard HTTP port but is often used for captive portals or for blocking access to certain websites or web services.

To implement HTTP auth captive using port 8002, you need to configure a web server or a network gateway to redirect all traffic to the captive portal page. Users connecting to the network will be directed to the captive portal page where they will be required to provide authentication credentials or agree to terms and conditions before accessing the network.

Here is an example code using Apache and PHP for implementing HTTP Captive Portal on port 8002:

1. Configure Apache to redirect all traffic to the captive portal page.

Create a virtual host configuration file for port 8002:

    ServerName captiveportal.example.com
    DocumentRoot /var/www/captiveportal.example.com
    ErrorLog /var/log/apache2/captiveportal.example.com-error.log
    CustomLog /var/log/apache2/captiveportal.example.com-access.log combined
    RedirectMatch ^/$ /login.php

This configuration redirects all requests to the captive portal login page (login.php).

2. Create the captive portal login page.

Create a PHP script (login.php) that presents a login form or terms and conditions acceptance form:

php

         Username:
         
         

         Password:
         
         

         
         ';
}
?>

This code checks if the user is already authenticated using the REMOTE_USER variable, and if not, displays a login form or terms and conditions acceptance page. If the user submits valid credentials, the script sets the REMOTE_USER variable, and the user is granted access to the network.

Alternatively, you can use an open-source captive portal software such as CoovaChilli, which provides advanced features like traffic shaping and integration with external authentication servers.

In summary, HTTP Captive Portal using port 8002 is a network authentication mechanism that requires users to authenticate or agree to terms and conditions before accessing the network. To implement this, you need to configure a web server to redirect all traffic to a captive portal login page and create a login script or use an open-source software like CoovaChilli.
