This is a part of network audit tools and lets you find details about users on a given host.
The finger service provides information about a user on a system. Typically one would use a command like finger rob@example.com. The application interface is simple and provides a large display area for the recovered information. All you have to do for finding information is to enter the user address. The query will find necessary details and display them for you. This works through the well-known finger service. It is part of a set of tools provided by the developers for network auditing. This is a service that could be dangerous. It provides extensive user information, which is extremely valuable for hacking. The Internet service providers may or may not have contact addresses available for people to report abuse. Finger service can help unearth such addresses. A program was created in 1971 to solve the need of users who wanted information on other users of the network. When you know who all are logged in, it becomes easier to determine that he is actually present in the office. You could then go meet him.
When a query is fired from this tool, it usually connects to port 79 of the remote host. The host starts a remote user information program or RUIP. This receives the one line enquiry and returns an answer, then initiates the close of the connection. The local host receives the answer and displays the same for you at the interface. This is a simple and handy tool and a good product. Because of the security concern, many servers may have this service disabled. It will work on local network if allowed by administrators.
