.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.
