safe_finger - finger client wrapper that protects against nasty stuff
from finger servers
command protects against nasty stuff from finger servers. Use this
program for automatic reverse finger probes from the
, not the raw finger command. The
command makes sure that the finger client is not run with root
privileges. It also runs the finger client with a defined PATH
will also protect you from problems caused by the output of some
finger servers. The problem: some programs may react to stuff in
the first column. Other programs may get upset by thrash anywhere
on a line. File systems may fill up as the finger server keeps
sending data. Text editors may bomb out on extremely long lines.
The finger server may take forever because it is somehow wedged.
takes care of all this badness.
