Hi,
I made several modifications to the latest source code of nfdump
(1.6.14-b1) to include support for PaloAlto netflow v9 extensions for
userid and appid.
I expect that can be of use to people with palo alto firewalls. Attached is
a diff with the modifications that I made to the code.
Best Regards,
Jose
