To my knowledge I thought Napatha was released on Jan. 27th 2001 by
Robert Keves. I saw it released on Packet Storm but, I did not see it on
Security Focus (or am I blind ;) ). Here is the description as follows
below.

naptha-1.1.tgz 5371 Jan 27 01:16:18 2001
Naptha v1.1 is a denial of service attack against many OS's which uses
established TCP connections to create a resource starvation attack. Includes
three tools - bogusarp makes a bogus entry in the router's arp cache so it
actually puts packets with our faked source address on the Ethernet,
synsend,
and srvr which replaces ackfin from Naptha 1.0. Tested against Windows 95,
98 and NT4 and more. Compiles on Linux 2.2.x, OpenBSD 2.7, FreeBSD 4.0.

I have not tested this as I have not had the time to do so since the
release.

i

results.
: finally, i tried a little shell script that opened multiple connections to
