NAME

       safe_finger  -  finger client wrapper that protects against nasty stuff
       from finger servers

SYNOPSIS

       safe_finger [finger_options]

DESCRIPTION

       The safe_finger  command  protects  against  nasty  stuff  from  finger
       servers.  Use this program for automatic reverse finger probes from the
       tcp_wrapper (tcpd) ,  not  the  raw  finger  command.  The  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.  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.
       safe_finger takes care of all this badness.
