What is the port number associated with the finger service?

The finger service is a protocol used to retrieve information about users on a network. It operates over port number 79. When a client connects to a finger server, it can request information such as user names, their login status, and details about their activities.

This service was more commonly used in earlier internet operations for user information sharing but has largely fallen out of favor due to privacy concerns and security vulnerabilities. Despite its decline in usage, understanding its historical context, along with the corresponding port number, is important for grasping how networking protocols have evolved.

The other port numbers mentioned correspond to different services: for instance, port 25 is typically used for SMTP (Simple Mail Transfer Protocol), port 22 is designated for SSH (Secure Shell), and port 110 is associated with POP3 (Post Office Protocol). Recognizing the unique role of each port helps in network configuration and troubleshooting, further emphasizing the significance of knowing the correct port number for services like finger.
