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

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