| 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. |

| 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. |
