ss: command not found on macOS

[richb-hanover]

Spurred on by Dave's Coffee Shop Bloat Test script, I decided to try it on my Mac (10.12.6) with Flent 1.3.0. This command seemed to work fine:

flent -x -H flent-fremont.bufferbloat.net -t Rich_Test --te=upload_streams=4 tcp_ndown

But I got a ton of error messages when I tried the second command using the --socket-stats option: there were none if I left that off. What other information could I provide? Thanks.

bash-3.2$ flent -x -H flent-fremont.bufferbloat.net -t Rich_Test --te=upload_streams=4 --socket-stats tcp_nup

Hi Rich, the unfortunately named socket stats binary ss, is as far as I can tell Linux only, so simply not present in the BSDs and their offspring. Best Regards Sebastian

Hmm, not sure there's anything to be done about that; as it says, that command doesn't exist on OSX. So, erm, just leave out the --socket-stats option? :)
