Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional, text-based communication session. It enables users to remotely access and manage devices such as servers, routers, and switches by establishing a virtual terminal connection over TCP/IP.

Key Features

  • Enables remote command-line access to networked devices
  • Operates over TCP port 23 by default
  • Text-based communication protocol
  • Allows for remote configuration and troubleshooting
  • Lacks security features like encryption, making it vulnerable to eavesdropping

Pros

  • Simple to use for basic remote terminal access
  • Widely supported across many operating systems and devices
  • Useful for troubleshooting legacy systems

Cons

  • Lacks security features like encryption, making it susceptible to interception
  • Superseded by more secure protocols such as SSH
  • Potentially dangerous if used over untrusted networks without safeguards
  • Not suitable for modern secure communications
