[smokeping-users] Fping strange behavior

[L B]

After some investigations, this happens only when there are VRRP addresses
in the fping command line . In my example, 10.0.254.254 and 10.0.4.1 are
virtual addresses.

fpinging VRRP addresses works if there are fpinged alone.

Anyone see what's wrong ?
