I tried pushing the minimum time between sending packets up as high as 10 seconds (-i10000) when testing from the command line, but while it somewhat helped (I got four packets back a couple of times) it didn't solve the problem- all the packets after the first few were still lost. Also note that I can run ping on this host with the "-i 0.0001" switch and get no packet loss-and I think that is rather faster than fping sends out its packets, especially if I give fping a high -i value. If I run ping with the -f switch, then I do start seeing some packet loss, but not the 100% loss I get with fping after the first couple of packets. Letting ping run for a couple of seconds with the -f switch, for example, only gave me 12% packet loss, and I was continually receiving packets. There is definitely something else going on here. I don't suppose there is a standard ping plugin for smokeping that I could use instead? That wouldn't fix the issues with fping, of course, but at least it should give me proper results.
