Hello steve.
wel, most of my machines are windows briks, and as far i know, windows
does not have SNMP installed.
and my switch is a dumbass model with no inteligence for SNMP
my OS is openBSD ,and it does not have iptables, it uses pfctlon it.
Previous router project was freesco, and with ipfwadm i could collect
all data i needed.
it even got worse now, i got a new modem from my ISP, and the stupid
brik has NO SNMP at al, so i have collect trafic data with statgrab
catching data on external eth card.

the only program that give me data per lan IP, is darkstat, but i am not
(yet) able to hack in the webserver stats....

so, i am bit stuck here.

thnxs for response.
