the local system's ARP cache, the lower layer code in the IP stack discards the
first packet and generates an ARP broadcast. The assumption (I guess) is
that the discarded packet will be retransmitted. You might look for the
"knobs" on fping to control timeouts and retry counts.</FONT></SPAN></DIV>

<DIV></DIV>Concerning fping options, I have some RRD graphs that show enormous
pings to some of our customer's (upwards of 800ms) because as the radio
doesn't pass any traffic it sits there and when someone first looks for it, it
acts kind of dumb. <BR><BR>What delegates how often the FPING command is
issued? I'm not looking for the arguments for fping itself, but rather
how hobbitd kicks fping into gear.<BR><BR>I would like to increase the rate of
the pings and see if that helps. I'm running a continuous ping over
night to see if that changes the graph or if it really does spike to that
outrageous height. <BR><BR>Josh<BR><BR>
