I just ran a ping on my Linux while doing a tcpdump. It still uses icmp,
both with a flood and without. I ran from a windows box and the same. The
basic windows ping command won't let you flood (the -f is for
fragmentation). I think your friend is wrong. However, he/she might be
confusing pings for traceroutes. In window tracert will use ICMP traffic,
but on a unix box it will use UDP traffic.

Hi All
My understanding of ping is that it uses icmp
however, a frend of mine told me that in a ping flood test,ping uses udp
because there is no need for acknowledgment
My understanding is icmp falls under the internetwork layer in DOD model
and
so when a ping command is executed,instead of using UDP,IP will use arp to
find the hardware address of the gateway (if the destination host is on
another network)
so who is right ?
