Port 2083 is commonly used for secure, encrypted access to the cPanel web hosting control panel. This SSL-enabled port provides administrators and users a secure interface to manage their hosting environment, including website files, email accounts, databases, and domain settings. Through HTTP over TLS/SSL (HTTPS), cPanel ensures that all transmitted data, such as login credentials and sensitive configurations, is protected from interception or tampering.

RadSec is a transport layer security (TLS) based protocol designed as a secure implementation of the RADIUS protocol. It protects RADIUS communication channels by encrypting data, ensuring confidentiality and integrity, making it suitable for exchanging authentication, authorization, and accounting information over untrusted networks such as the Internet.

Which one is on your host

ask the machine, not the registry

The registry says what 2083 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':2083\b'
macos
lsof -nP -iTCP:2083 -sTCP:LISTEN
windows
netstat -ano | findstr :2083

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 2083 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
