   6  * This was written to test what size TCP fragments would get through
   7  * various TCP/IP packet filters, as used in IP firewalls.  In certain
   8  * conditions, enough of the TCP header is missing for unpredictable
   9  * results unless the filter is aware that this can happen.

  11  * The author provides this program as-is, with no gaurantee for its
  12  * suitability for any specific purpose.  The author takes no responsibility
  13  * for the misuse/abuse of this program and provides it for the sole purpose
  14  * of testing packet filter policies.  This file maybe distributed freely
  15  * providing it is not modified and that this notice remains in tact.
