-.TH SAFE_FINGER 8 "21th June 1997" Linux "Linux Programmer's Manual"
-.SH NAME
-safe_finger \- finger client wrapper that protects against nasty stuff
-from finger servers
-.SH SYNOPSIS
-.B safe_finger [finger_options]
-.SH DESCRIPTION
-The
-.B safe_finger
-command protects against nasty stuff from finger servers. Use this
-program for automatic reverse finger probes from the
-.B tcp_wrapper
-.B (tcpd)
-, not the raw finger command. The
-.B safe_finger
-command makes sure that the finger client is not run with root
-privileges. It also runs the finger client with a defined PATH
-environment.
-.B safe_finger
-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.
-.B safe_finger
-takes care of all this badness.
