connections (i.e. to port 21) to public FTP servers at the Lawrence
Berkeley National Laboratory during a ten-day period.

The trace ran from Jan 10-19, 2003, containing 22 thousand connections
and 3.2 million packets. The connections are between 320 distinct
servers and 5832 distinct clients.
The traces have been "sanitized" using the Bro anonymizer to
remove private information, such as passwords and remote client
The description of the tool can be found in the publication below, and
the detailed anonymization scheme is described here.
The traces were made by Ruoming Pang (email@example.com)
and Vern Paxson (firstname.lastname@example.org).

- 16 separate trace files, each spanning either approximately a day
(e.g., lbnl.anon-ftp.03-01-10 spans January 10, 2003) or in a pair
spanning a day (e.g., lbnl.anon-ftp.03-01-12A and lbnl.anon-ftp.03-01-12B
together span January 12, 2003, with the 'A' trace being followed after
a short gap by the 'B' trace):
- One glued-together trace file (which has some gaps, as the traces
don't quite overlap):
lbnl.anon-ftp.Jan10-19.2003 (84 MB; 310 MB uncompressed).
