Hello Everyone,
I hope someone can point out what I'm doing wrong. The problem is I don't
see ntop collecting any netflow data. I have set up the router ok, as I'm
seeing stats on protocols and exports fine, but it never seems to make it to
the ntop box for processing. Here's how I'm configured:
Cisco edge router:
serial0:
ip route-cache flow
Netflow export config:
ip flow export xxx.xxx.xxx.xxx(NAT IP thru FW to ntop box)
port 2055 version 5
Netflow aggregation config:
ip flow-aggregation protocol-port
cache entries 2046
cache timeout inactive 200
cache timeout active 45
export destination xxx.xxx.xxx.xxx (NAT) 2055
enabled
FW has access list allowing 2055 (default netflow plugin port on Ntop) from
router address
Ntop started like this:
/usr/local/bin/ntop -i eth0 &
Netflow plugin config:
Incoming Flows Local Collector UDP Port: 2055
Virtual Netflow Interface Local Network IP Address/Mask:
xxx.xxx.xxx.xxx/mask (ip and mask of eth0)
White List IP Address/Mask(s) we store data from:
xxx.xxx.xxx.xxx/mask (ip and mask of router)
Black List Blank
Outgoing Flows Blank
Debug On
What am I missing?
Thanks in advance.
John H.
