Great, Gaspard!!! That's what I'm looking for. Thanks a lot for your help.

I launch it this way.

nfcapd -w -D -l /netflow/spool/allflows -p 9996

If you see my output I don't get the "create" and "delete" events
either, so there's something I'm doing wrong.

Thanks a lot for your help

Kind regards

Octavio
