#5 Packet loss

[Anonymous]

fping show me 50% packet loss, but icmping show 0% packet loss

fping host -c 10 -b 512
host : [0], 540 bytes, 99.8 ms (99.8 avg, 0% loss)
host : [2], 540 bytes, 1102 ms (601 avg, 50% loss)
host : [6], 540 bytes, 101 ms (434 avg, 57% loss)
host : [7], 540 bytes, 104 ms (351 avg, 50% loss)
host : xmt/rcv/%loss = 10/4/60%, min/avg/max = 99.8/351/1102

ping host -c 10 -s 512

I too have seen that same behaviour. While looking at this, I noticed that fping does not apply a sequence number to a ping, but maintains the id number.
