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

       safe_finger [finger_options]

       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  com-
       mand. The safe_finger command makes sure that the finger client is not run with root priv-
       ileges. 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  for-
       ever because it is somehow wedged.  safe_finger takes care of all this badness.
