finger protocol

The Finger protocol is used to search for the user identification.

The finger protocol supports the search for a person's user ID and IP address if their Internet node is known. In addition, the finger protocol can be used to determine which users are currently active. On many systems, access to the local Finger service is not possible for security reasons. In these cases, the other methods of obtaining user information must be used.

The finger command can also be used on the network to determine requests to a particular host via connected hosts or a particular user on a particular host.
