Hello, i'm from Russia, so sorry my english please.
We have:
1. Sensor:

# pkg_info | grep softflowd
softflowd-0.9.8_2   Softflowd is flow-based network traffic analyser with expor

Start softflowd daemon like:
/usr/local/sbin/softflowd -v 9 -i lan -n COLLECTOR:9998 -p /var/run/softflowd.lan.pid -c /var/run/softflowd.lan.ctl -m 819200 -t maxlife=20m -t general=20m -t tcp=20m

Start collector nfcapd like:
/usr/local/bin/nfcapd -w -D -z -n SENSOR sensor_ip /tmp/netflowv9 -p 9998 -t 300 -u username -g usergroup -P /tmp/netflowv9/9998.pid -x /tmp/netflowv9/nfcapdmv -B 200000


So, we have this:

Wrong "Date flow start" and "Duration Proto" ...

PS: On the page http://www.freebsd.org/ru/ports/net-mgmt.html for port softflowd-0.9.8_2 we need packages: gettext-0.18.1.1, gmake-3.82, libiconv-1.13.1_1, but we haven't install gmake-3.82 before ... It can be a reason?
Comment 1 a-zazell 2011-10-19 18:40:14 AEDT 
Now we install nfdump on Sensor machine:

# pkg_info | grep nfdump
nfdump-1.6.4        Command-line tools to collect and process NetFlow data

Same problem ...
Comment 2 a-zazell 2011-10-20 06:30:17 AEDT 
Now i try this:

#softflowd -i lan -n 127.0.0.1:9998 -p /var/run/softflowd.lan.pid -c /var/run/softflowd.lan.ctl -t maxlife=300
#nfcapd -w -D -z -n local,127.0.0.1,/tmp/netflowv9 -p 9998 -t 300 -P /tmp/netflowv9/9998.pid -B 200000

And we have norm output:

# nfdump -r nfcapd.201110192310
