[flow-tools] problem: src as is 0

[Olav Langeland]

I am new to flowtools, and installed 0.57 on a FreeBSD 4.5 machine. Our
setup is 2 Cisco 7206 with 2 ISP hooked up, our own AS. Exporting flows
from just 1 router now, and looks good, exporting, collecting, saving. I
want to use it for billing and general network statistics. Exporting
netflow v5.

When I try to extract some AS information I get this:
--cut--
$flow-cat -p ft-v05.2002-04-13.* | flow-stat -f19 -P -p -S4 | less
# src AS    flows    octets   packets
#
0           44.659   86.779   52.008
3320        8.773    2.330    8.029=20
5430        0.960    0.195    0.975=20
etc.
--cut--

This seemed to work when I tested the Cisco Netflow software. Any help
appreciated, I didnt find any other posts about this when I skimmed
through the mailinglist archive (probably hidden somewhere).

thanks,
