I haven't tried this in years, but I used to be able to send mail from anyone who was logged in by writing a little script that disconnected the controlling terminal of my process and then pointed at the writable terminal of someone currently online (thus adopting that terminal as the controlling terminal of my process). Then getlogin() would think I was them. Terminals are less writable these days, of course, but I still won't use getlogin() for anything. I couldn't find "setlogin" under Linux or Solaris 2.6. -- -IAN! Ian! D.
