Why can't you use hosts.deny? A while back I found that a certain
person was using ``xhtalk'' to finger my machine a lot. He had
xhtalk in his .xinitrc, so if he logged into multiple machines
I'd get double action. I adde this to my hosts.deny file:
in.fingerd:.somehost.on.my.campus.edu:twist=/bin/nice -20 /usr/ucb/yes
This causes xhtalk to die in a very interesting way, and quickly,
so that the ``yes'' immediately stops on your machine, consuming
no CPU time locally. xhtalk on the other hand begins to consume 90+%
of the CPU.
Yeh, I was in a bad mood when I did this. The real best solution
is to email the remote admin and ask him to take care of it for you.
