On current iputils ping (seems to be default on most linux distros) you should be using flood ping for this:

    # ping -f x.x.x.x
As superuser or su -c / sudo of course. You'll get a nice real time bar chart of packet loss. I use it all the time for (edit: local) network testing.

That's fine on your local network. If you're pinging a system out of your local network, what you're doing is considered by many to be a denial of service attack.

It's not even close to the most effective denial of service attack, but if I were to do that from my 100 Mbps Internet line I could overwhelm many company's Internet lines with a simple ping flood.

Sure. I added "local" about a second after posting for this reason. However even with -f you can just specify an interval when running tests outside your lan.
