Subject: ping: What's the purpose of rate limit?

Hello,

Excuse me, I searched but didn't find an answer --

What's the purpose of setting a limit to the "-i" and "-l" parameters
of ping for non-root users?

It seems that this is only intended to prevent accidental misuse
because these restrictions can be easily worked around by starting
multiple instances or wrapping the program in a loop, e.g.,
while true; do ping -l3 -c3 192.168.0.1; done

(Please Cc to me because I'm not subscribed to this list. Thanks!)

Guan
