I have the same problem on about 10 rasbperry-pi installations.
Linux moni 4.14.98-v7+ #1200 SMP Tue Feb 12 20:27:48 GMT 2019 armv7l GNU/Linux
ss utility, iproute2-ss161212 Has anyone found at least a workaround?I don't want to disable rkhunter hidden_ports test, but those false positive are reporting each day.
Regards
