I had a quick look at the code and couldn't immediately recognise the Linuxisms in question, but haven't done a thorough look. On FreeBSD, I tend to filter traffic by src and destination ip/port to determine how much traffic an application is using. Easiest solution I can think of: Use net-mgmt/darkstat. https://unix4lyfe.org/darkstat/ Slightly more complicated solution, but with potentially more power for filtering the data: Netflow/NfDump/NfSen https://forums.freebsd.org/threads/49724/ Good luck!
