Pfflowd software enables OpenBSD PF to support Cisco NetFlow datagram exporting, facilitating the collection of network traffic data.
If you're looking for a way to export Cisco NetFlow datagrams for use with OpenBSD PF, pfflowd is an excellent choice. This software is a small daemon that takes real-time state expiry messages from OpenBSD's PF packet filter and converts them into Cisco NetFlow datagrams. As a result, you can keep track of traffic accounting with NetFlow-capable tools without adding much load to your PF firewall.
One of the best things about pfflowd is its ease of use. The supplied manpage contains plenty of information about how to use the software and its functions, which you can view ahead of installation using the following command:
$ /usr/bin/nroff -mandoc pfflowd.8 | less
The latest version of pfflowd comes with some noteworthy updates. For instance, it only supports pfsync(8) version 3, and there is a workaround for 32-bit NetFlow v.1 and v.5 counters. These updates help to ensure that the latest version of pfflowd runs smoothly and provides the best possible experience. Overall, pfflowd is a great option for anyone looking to export Cisco NetFlow datagrams for their OpenBSD PF.
