Is there a modified ping?

Can somebody tell a the name of a tool that can be used to send ICMP
packet
of size > 64K on windows. i have to crash a machine using ping of
death
as
my first assignment in Pen-Testing class. i am unable to do this
using
the
biult in ping utilities in windows and linux. i could not find any
tool
on
the internet as well.

You didn't look very hard then... that is, if you really are 'in
Pen-Testing class' my friend ;)

Drop to a shell on *nix and type 'man ping'. I'm running SuSE 8.2 and
I
found this option, which is also present in the ping on my OpenBSD
box:

      -s packetsize
      Specifies  the number of data bytes to be sent.  The default is
      56, which translates into 64 ICMP data bytes when combined with
      the 8 bytes of ICMP header data.

You'll probably have issues if you aren't root.

I've seen other stuff available for windows but that was some time ago
and I don't remember much. You're at a serious, serious disadvantage
if
you want to do pen testing or serious security work and you're only
going to use windows.

Some places to look for stuff:
http://www.packetstormsecurity.org
http://www.insecure.org/tools.html

Quite honestly, you could probably lurk and use nothing but the
www.packetstormsecurity.org site and get all you need off there. It's
one of the best resources period.
