Description pavel.janik 1998-11-20 06:26:25 EST

ping -f localhost as root it should be obvious:

--- localhost ping statistics ---
1847 packets transmitted, 177 packets received, 90% packet
round-trip min/avg/max = 0.9/42.4/84.9 ms

90% is bad...

Not a bug, you are flood pinging.  Not every ping request will come

You are hammering the networking code in the kernel, it can't keep up.
Comment 2 Marc MERLIN 1998-11-28 01:59:59 EST
Actually Pavel is most likely using a recent 2.1 kernel. There is a
known problem with the ping binary.
Please look at:

(If you don't know who Alexey Kuznetsov is, he did a _lot_ of TCP/IP
work in the 2.1 kernels)
