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

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