Some possibilities:

flow-tools - collects and processes NetFlow data
flow-tools-dev - development files for flow-tools
fprobe - export captured traffic to remote NetFlow Collector
fprobe-ng - export captured traffic to remote NetFlow Collector (meta)
fprobe-ulog - export captured traffic to remote NetFlow Collector (ULOG
version)
libcflow-perl - perl module for analyzing raw IP flow files written by
cflowd
nfdump - netflow capture daemon
pmacct - promiscuous mode traffic accountant
root@charles-laptop:~#
This is on Ubuntu 8.04.
