flow-tools vs cflowd

Why use flow-tools instead of cflowd?

  • flow-capture preserves the sub-second portion of the NetFlow timestamps that cflowd discards
  • flow-tools is easier to build because it is written in portable C. Problems with building cflowd may occur because it requires cutting edge C++ features
  • flow-tools is actively maintained, and supports newer NetFlow versions, including those from the popular Cisco Cat6K series platforms

apt-get install fprobe-ng flow-tools flowscan flowscan-cuflow flowscan-cugrapher rrdtool
mkdir -p /var/lib/netflow/ft
mkdir /var/lib/netflow/rrds
mkdir /var/lib/netflow/scoreboard

Dejar /etc/flow-tools/flow-capture.conf solo con:
