RADIUS (Remote Authentication Dial-In User Service) is a networking protocol used for authentication, authorization, and accounting (AAA). It helps manage user access in network environments like Wi-Fi, VPNs, and enterprise security systems. RADIUS ensures secure and centralized access control.

Features of RADIUS:

• Centralized authentication and authorization management
• Supports multiple authentication protocols (PAP, CHAP, MS-CHAP, EAP)
• Secure communication with encryption and logging
• Extensible with various database backends (MySQL, PostgreSQL, LDAP)

Database and default credentials details are saved in the credentials.txt file located at cat /var/www/credentials.txt directory.

Access the RADIUS server using the appropriate client applications or through the CLI for configuration and monitoring.

To check the installed RADIUS version, use the following command:

radiusd -v

Disclaimer: RADIUS is an open protocol implemented in various open-source and proprietary software solutions. Users should configure and use it according to security best practices and licensing requirements.
