config FREETZ_PACKAGE_NFDUMP bool "nfdump 1.6.2 (binaries only)" default n help The nfdump tools collect and process netflow data on the command line: NFDUMP tools overview: All tools support netflow v5, v7 and v9. - nfcapd - netflow capture daemon. Reads the netflow data from the network and stores the data into files. Automatically rotate files every n minutes. ( typically ever 5 min ) nfcapd reads netflow v5, v7 and v9 flows transparently. You need one nfcapd process for each netflow stream. - nfdump - netflow dump. Reads the netflow data from the files stored by nfcapd. It's syntax is similar to tcpdump. If you like tcpdump you will like nfdump. Displays netflow data and can create lots of top N statistics of flows IP addresses, ports etc ordered by whatever order you like. - nfreplay - netflow replay Reads the netflow data from the files stored by nfcapd and sends it over the network to another host.
