2/26    If you have comcast in berkeley, would you please do some fast
        pinging and find out at what rate do you start to get packet loss
        (of ICMP ping packets). I moved out of state and can only send 2
        pings a second.  I want to tell the comcast folks here what the
        ping rate in berkeley is. If I remember correctly, it was much
        higher. Thanks.
        \- 2ping/sec ... you arent hitting the sun icmp throttle are you?
           why do you need to send pings faster? --psb
            \_ To rapidly gather network link quality statistics.
                I can _send_ pings faster than 2/sec, but they get
                dropped by the comcast equipment upstream.
                What's the "sun icmp throttle"?
                    \- you have exceeded your anonymous privilages --psb :-)
                        \_ Why do you care?
                           \_ Falls under the "self righteous prick" policy.
                \_ comcast will not let you "rapidly gather network link
                   quality statistics."  That's their job, and there's no
                   reason they'd want to let you hose their network.
                   \_ In berkeley I could ping > 2/sec.
                      In portland I can not. Same comcast company.
                      A network cannot be hosed by 50 pings /second.
                      I'm not doing anything malicious. When the network
                      has problems, I like to run mtr.  Would somebody in
                      berkeley please run a short test to determine what
                      the icmp limit is there?
                      \_ What if all 200 people on your local net sent 50/s?
                         \- the throttle is probably an anti-DoS measure in
                            part. i dont think this is too unreasonable.
                            blocking all icmp echo/echo_reply would suck.
                            again, you can use tcp/udb echo ... it might be
                            intersting to see if you can basically write ping
                            with getnetmask --psb
                         \_ Would you be concerned if they raised it to 20/s?
                         \_ Would you have a problem if they raised it to 20/s?
                         \_ Hey, they didn't have this low a limit in
                            Berkeley, and the sky did not fall. Could you just
                            find out what the Berkeley limit is. That's all.
