        **What is rlogin?**

        rlogin (remote login) is a legacy network protocol used to log into another Unix-based system over a network. It allows users to access remote systems and execute commands as if they were logged in locally.

        **Why is rlogin useful?**

        * Enables remote shell access to Unix systems.
        * Useful for basic remote administration and file operations.
        * Simple and lightweight for trusted, internal networks.
        * One of the earliest remote terminal protocols before SSH became common.

        **How it works?**

        * The client initiates a TCP connection to the remote rlogin server.
        * The user is authenticated, often using `.rhosts` or similar mechanisms.
        * Once authenticated, the user gets a terminal session to the remote host.
        * Data is transmitted in plaintext, including login credentials.

        **Where is rlogin used?**

        * Historically used in Unix-based networks for remote administration.
        * Still found in legacy systems or educational environments.
        * Rare in modern environments due to security concerns.
