Accessing and Configuring the Web UI

The qBitTorrent-nox web UI allows you to manage your torrents from a web browser. By default, the Web UI can be accessed on port 8080.

1. Default Web UI Access Information: Open your web browser and navigate to http://your_server_ip:8080. Replace your_server_ip with the actual IP address of your CentOS Stream 10 server.
2. Logging in with Default Credentials: The default username is admin and the password is adminadmin. It is crucial to change these credentials immediately after logging in.
3. Changing the Default Username and Password:
   • Go to Tools > Options > Web UI.
   • Change the username and password to a secure combination.
4. Configuring Remote Access Settings: To access the Web UI from outside your local network, you need to configure port forwarding on your router. Forward port 8080 (or your chosen port) to your server’s internal IP address.
5. Setting up Authentication: Ensure that authentication is enabled in the Web UI settings. This requires users to log in before accessing the interface.
6. Securing the Web UI with HTTPS: For added security, enable HTTPS for the Web UI. This encrypts the traffic between your browser and the server. You will need to generate a TLS certificate for this.
7. Configuring Firewall Rules to Allow Access: Configure your firewall to allow traffic on the port you are using for the Web UI. For example, if you are using port 8080, run:

sudo firewall-cmd --permanent --add-port=8080/tcp
