digitd is a simple and safe finger daemon, ready-to-run out of the box, yet easy to customize. It allows users to opt in to being fingerable, rather than the usual opt-out.

digitd is distributed under the GNU General Public License version 3, or, at your option, any later version.

It is based on Radovan Garabik’s efingerd, simplified and completely rewritten.

digitd implements the Finger User Information Protocol as described in RFC 1288: http://tools.ietf.org/html/rfc1288

See the man page digitd(8) for more information.

Installation

Requirements: Perl on a system supporting syslog (GNU/Linux, macOS,…)

1. As root, type: make install
2. Add this line to /etc/inetd.conf

finger	stream	tcp	nowait	nobody	/usr/sbin/tcpd	/usr/local/sbin/digitd

If there is already a finger line, comment it out. Note that the entries are separated by tabs, not spaces.

You can create a user under which the daemon should run (e.g. digitd), in which case its name should replace nobody in the line above.

3. Restart inetd with: killall -HUP inetd
