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. |
