ipsend/ipsend.h

/*
 * ipsend.h (C) 1997-1998 Darren Reed
 *
 * 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 gaurantee 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.
