ipsend is a tool that generates TCP/IP packets with a scripting language. 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.

This distribution contains *ONLY* the code required to build the 'ipsend'
directory of programs (including man pages) found in the IP Filter package.
