Hello, I have nfdump and nfsen installed.
The problem is that when I test with nfcap which sends the router for data,
no data arrive, but always an error:


root@nfsens:/tmp# nfcapd -E -p 6343 -l /tmp
Add extension: 2 byte input/output interface index
Add extension: 4 byte input/output interface index
Add extension: 2 byte src/dst AS number
Add extension: 4 byte src/dst AS number
Bound to IPv4 host/IP: any, Port: 6343
Startup.
Ident: none, Error reading netflow header: Unexpected netflow version 0
Ident: none, Error reading netflow header: Unexpected netflow version 0
Ident: none, Error reading netflow header: Unexpected netflow version 0



i Use a Brocare CER2024 as Router.

i have enable sflow on the router

sflow enable
sflow destination x.x.x.x

on the uplink port   sflow forwarding


There are other parameters, so I can get the data in the correct format?


kind regards rolf
