About:
Telnet is a command-line utility that provides an interface to the TELNET protocol, enabling bidirectional interactive text-oriented communication. It allows users to establish a connection to a remote host or port, facilitating terminal emulation and network testing. This tool is essential for managing legacy systems and debugging network services that rely on this protocol.

Key Features:

Terminal emulation for remote host interaction
Manual protocol negotiation and option handling
Standard input/output redirection capabilities
Built-in escape sequence support for session control

Use Cases:

Connecting to legacy mainframes or network equipment
Debugging plain-text network services and ports
Performing manual protocol handshakes for testing

Alternatives:

SSH – Provides encrypted, secure communication, whereas Telnet transmits data in cleartext.
Netcat – Offers more versatile raw TCP/UDP connection capabilities for complex scripting.
