Hello. I don't have any experience with Debian but in OpenSuSE and Ubuntu, also in Rasbian (Rasberry PI deviant of Debian) fping needs to be setuid root, or you get the same behavior (no data). Try and get a listing for fping with a similar command to this (depending on fping's location): ls -al /usr/bin/fping if you get something like this (not the s after the w) it should be fine: -rwsr-xr-x 1 root root 30460 Aug 13 2014 /usr/bin/fping If not, the you need to do the following:
chown root:root /usr/bin/fping chmod u+s /usr/bin/fping Btw the solution to this is not mine. Someone using FreeBSD had a similar problem and Tobi (the well know Tobi) answered him so I have kept that answer in my notes. Here it is in full: > Hello, > > I just tried upgrading fping on a FreeBSD host I have smokeping > 2.6.7 running on and (to fping 3.4) and I noticed the graphs > broke.

I guess you have to install fping setuid root: chown root:root /usr/sbin/fping chmod u+s /usr/sbin/fping cheers tobi So there you go, I hope it helps. Good luck!
