I maintain a .plan file and finger server at peter@tcp.rip / finger://peter@tcp.rip/ if you want to try something out.
Back in the 90s, it was good fun seeing all the stuff people put out on finger. Aside from the link someone else posted to Shodan, is there a list of finger servers anywhere?
(fingering the main host will give you a list of quirky options, including how to get the current server cpu temperature)
