Fuehlt sich jemand berufen, das zu checken?

CFINGERD also takes into account any security breaches,
and attempts to close them. With the added bonus of cre-
ating ".nofinger" files, this is displayed instead of fin-
ger information, making it possible for users to keep
themselves relatively anonymous from outside users.

X-Status: F
package: cfingerd
Version: 1.3.2-9
cfingerd is supposed to *display* the contents of ~user/.nofinger, not
just print nothing at all. With the stock cfingerd.conf, this doesn't
happen, as I think the following demonstrates sufficiently. This used
to work but I don't know how long ago. (I have some users that really
do wish to remain hidden [on another system], I'd *rather* have some
way to indicate "just display the contents of
/etc/cfingerd/nouser_banner.txt for this user" but that's a seperate
issue... it should instead at least work as documented....)
