Thanks for this email Blake, regarding the router, i am quite sure it exports the flow correctly and it comes to my ntop collector, if i do a netstat -a it listens to 2055 (udp)and if i repetedely do the netstat command i can see that a que builds up and the next time i issue the command it's gone. And my old dual pentium pro machine sounds like an russian traktor :-)
But i cannot recall that i switched NIC under the admin menu, i will try that Best Regards, Rickard ----- Original Message ----- From: "Blake" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, February 26, 2003 6:20 PM Subject: Re: [Ntop] make ntop show netflow > > FYI - search NTOP archives because I know personally I > have had this issue before.
