PFFLOWD - send netflow on schedule
-
I have just installed pfflowd and am using a tool called scrutinizer made by a company called plixer to analyse the packets. it is complaining that pfsense is not sending it netflow datagrams in a timely manner. is this a simple addition to the package config page? as well, i cannot seem to get the serivce to start if i tell it i want a v5 datagram. if i select v4, bitshark (ehtereal) shows that the packets coming from it are v5, but inside the data of the packet it shows v4. i am not sure how accurate bitshark's interpretation of netflow packets is, but i hope that this is good information nonetheless.
