5 *
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.
10 *
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.
