I get the following error when running the following command: ``` % flent rrul -p all_scaled -l 60 -H netperf.bufferbloat.net -o test-flent.png Starting Flent 2.0.1 using Python 3.9.6. Starting rrul test. Expected run time: 70 seconds. WARNING: Found fping, but it outputs broken timestamps (off by 1628602397.488081s). Not using. ERROR: Runner Ping (ms) ICMP failed check: Cannot parse output of the system ping binary (/sbin/ping). Please install fping v3.5+. ````` I have fping 5 installed. I'm not sure if this is an issue with my Mac or with the install. How would I tell. I am running macOS Big Sur 11.5.1 and installed flent using home-brew according to the documentation. -- You are receiving this because you are subscribed to this thread.
