Install cfingerd by entering the following commands in the terminal:
sudo apt update sudo apt install cfingerd
configurable finger daemon
This is a free replacement for standard finger daemons such as GNU fingerd and MIT fingerd. Cfingerd can enable/disable finger services to individual users, rather than to all users on a given host. It is able to respond to a finger request to a specified user by running a shell script (e.g., finger firstname.lastname@example.org might cause a sound file to be sent) rather than just a plain text file.
