apinger still giving unrealistic low RTTs after some time. Restarting it always fix it.
It IS pinging the correct "monitor" IP, I can see it through tcpdump
12:36:47.624421 IP 201.72.x.x > 72.14.197.x: ICMP echo request, id 19774, seq 46876, length 60
12:36:47.697697 IP 72.14.197.x > 201.72.x.x: ICMP echo reply, id 19774, seq 46876, length 60
But this third ping is totally bogus. And after some time all three pings will be as low as the third one.. nearing 0
