Hello Paul
I still have this issue (partially). People in this list said me there
is a rule blocking the traffic, but iptables/ip6tables and selinux are
shutdown or disable (how you say). I found that nfdump saves data only
if they come from same network (from server's point of view), I
explained it here:
http://www.mail-archive.com/[email protected]/msg00810.html
It works but I don't know why I can't set other internal interface as
source interface in the router's config (ip flow-export source
<interface>). The routing is OK and iptables/ip6tables/selinux are down.
If you solve this, please report it to the list.
Saludos,
Fabián Mejía

Hi,
I'm building nfdump-1.6.10 and nfsen-1.3.6p1 on a RHEL
6 server. I've shutdown iptables and ip6tables and have selinux set
to disabled. Eventually, I'll need all of those running.
Like a few others before me, I'm not getting anything
in the data files. All of them are sized at 276 bytes. IE no data.
I have tcpdump running on the port and I see packets
come in every 5 seconds from the router, actually it's an ASA.
I configured nfdump with: --enable-nsel
--enable-nfprofiles --enable-nftracker. And various combinations of
all three of those. But never any data.
Sorry, I can't cut and paste, it's a physically
separated network, no access from outside.
Is there a way to look at the tcpdump data to see if
that is good stuff, or is there a way with nfcapd to give more info on
why its ignoring the packets.
My setup and observed results are identical to this
thread:
http://www.mail-archive.com/[email protected]/msg00807.html
though my packet sizes on the tcpdump are larger. 1000
to 1500 bytes mostly. I have followed the advice of both replies, to
no avail.
Any help would be appreciated.
Thanks,
Paul.
