</div></div></div></div></div></blockquote><div><br>My current router does not support fprobe or NetFlow. <br><br>However, ntop acts as a NetFlow collector. <br><br>And fprobe is just a Linux package and therefore (theoretically at least) it should be able to run on an OpenWRT router.<br>
<br>So, in theory, the OpenWRT router will have fprobe and then send NetFlow data to ntop on another server, and we should be in business.<br><br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204, 204, 204);padding-left:1ex;">
