functionality.
- Remove space from ICMP type/code when followed by an IP address
2006-07-21 snapshot-20060809
- Make nfexpire ready for profile expiration
- Fix bug in nfrpofile. sub dir hierarchy not handled correctly.
2006-07-21 snapshot-20060721
- Add -N option for plain number output in summary line

- Do recursive file selection when a directory is given by -R
2006-06-14 snapshot-20060621

Note: This changes the default aggregation behaviour, but gives more
flexibility
- Add tos to element statistics list
2006-06-14 snapshot-20060614
- Add additional stat line at the end of output
- Add new binary nfexpire. Manages data expiry on time and/or size based limits
Includes new bookkeeping records in nfcapd. See nfexpire(1)
- Add ICMP type/code decoding in flow listing instead of dst port
- Add packet repeater in nfcpad/sfcapd. In addition, incoming UDP packets can

in the argument handling. No idea how this was supposed to work, but
consider running it in / with relative arguments.
Bump revision.

The nfdump tools collect and process netflow data on the command line.
Nfdump tools:
nfcapd - netflow collector daemon
nfdump - netflow dump
nfprofile - netflow profiler
nfreplay - netflow replay
nfclean.pl - cleanup old data - installed as example
ft2nfdump - read flow-tools format - optional tool
sfcapd - sflow collector daemon - optional tool
