As a very simple but useful workaround in this case, you can use a
fingerd that immediately fingers back to the host it receives a request
from, thus revealing potential userid of people who are fingering your
system. Have a look at ftp.win.tue.nl:~ftp/pub/logdaemon.tar.Z
(available for anon. ftp). It contains various utilities of this
kind written by Wietse Venema.
