Hi,

im new to netflow and flow-tools and i hope i�ll find someone who can help
me with my question (maybe it�s only a question of understanding netflow).
I use flow-tools version 0.66 and it�s running very well. I use flow-capture
to collect netflows from 5 backbone routers. I started 5 different
flow-captures with different working dirs and ports to listen on, so that
the flows from each router is seperated. 

flow-cat </dir/router1> | flow-stat -f10 > filerouter1 
flow-cat </dir/router2> | flow-stat -f10 > filerouter2
flow-cat </dir/router3> | flow-stat -f10 > filerouter3
... gives me information for accouting

for accouting, i will cut these filerouter1-3 togehter (sortet by
source/dest. ip) 
filerouter1,2&3 -> fileallrouters
if i have connections which go over multiple routers, i have some entries
like this

# src IPaddr  dst IPaddr     flows    octets  packets
81.92.x.x     80.50.x.x      1        59      1 (same connection on router1)
81.92.x.x     80.50.x.x      1        62      1 (same connection on router2)


i take the entry with the highest byte count for my accounting (router2) and
delete the others
Is there any (flow)tool available which makes this automated? (check for
some connection over multiple router log files and take only the entry with
highest byte count) what flow-tools should i use for accounting ?

There are some connections in my logfiles which i dont understand, like this
example


# src IPaddr  dst IPaddr     flows   octets   packets
81.92.x.x     213.240.x.x    5       1403     7  (same connection on
router1)
81.92.x.x     213.240.x.x    3       2813        15 (same connection on
router2)

How is it possible , that an entry with 5 flows has less bytes than an entry
with 3 flows ?
Thanks for your help and sorry about my very, very bad english 

greets
mike
