It _is_ silly. It's a silly daemon. An imp, if you will.

Yeah...actually, it's a reaction to paranoid admins here and at
mmy .mil site who shut down in.fingerd to keep skumbags from getting
userlists. Overkill, IMHO.
At least my way,, you can explicitly finger a given user.

True. Geez, Pete I _said_ it was pathetic! The root part was

Actually, the whole thing was an exercise in Perl. Eventually, I want to
make it more configurable, lose the special behavior for fingering root,
disallow pass-through fingering (which is stupid in the first place), and
make a few other changes, as well.
On a WWW site where normal users can't do CGI, working
on a way to use named pipes to run programs from my
Web pages. If I could get a few hours without interruption....
