A finger server is a daemon that answers finger protocol queries (port 79), returning a user's .plan and .project files to anyone who asks. Running one makes your .plan reachable from outside the machine.
tilde.town and tilde.pink both run a finger daemon: no setup needed. Your ~/.plan is served automatically:
finger you@tilde.town finger you@tilde.pink
fingerd (classic, OpenBSD/NetBSD standard) or finger2000 for modern Linux.
Minimal setup with fingerd (inetd-based):
sudo apt install fingerd # add to /etc/inetd.conf: # finger stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/in.fingerd sudo service inetd restart
Verify:
finger youruser@localhost
~/.plan: what you're working on (free-form text)~/.project: one-line current project descriptionchfn), last login timeSee .plan and .project for what to write.
