pktanon - profile-based traffic anonymizer 



       pktanon [-c profile_file] input_file output_file


       pktanon [options] [input_file] [output_file]

Pktanon is a generic framework for network traffic anonymization. It aims at enabling wide-spread use of realistic network traces by providing fine-grained, profile-based anonymization. It can easily be configured by anonymization profiles, which are used to define how the network traffic should be made anonymous. Such profiles ensure an easy adaptation of the information actually being made anonymous to different environments or local legislation.

Configuration:

anonymization profile

Input Parameters:

read first snaplen bytes from each packet (for both captures and files) [default:256]
capture packets from this interface
do not set interface in promiscuous mode
filter specification for libpcap
use linux raw sockets instead of libpcap (-e option is not available)

Output Parameters:

output (to file) is flushed every N packets
send packets to <interface> using libpcap-inject

send packets to Addr:Port using sockets

(if '--socket' option is set:)

-6, --use-ipv6
Use IPv6
Use UDP

Miscellaneous:

use libpcap for file i/o
print this message and exit
Reduce output
Increase output

PktAnon needs a configuration file. Sample configuration files can be found in the profiles directory in the distribution. This directory also includes a sample network trace. Two included configuration files are ’profile-identity.xml' and 'profile.xml'. The first configuration copies all the fields from original packets into anonymized packets except that packets content is cropped. The second configuration anonymizes mac addresses, ip addresses, and ports in the packets.

To anonymize sample trace using sample configuration files run:



    pktanon -c /usr/share/doc/pktanon/examples/profiles/profile-identity.xml profiles/sample.pcap out.pcap
or 



    pktanon -c /usr/share/doc/pktanon/examples/profiles/identity.xml profiles/sample.pcap out.pcap
The output should look like this:

pktanon --- profile-based traffic anonymization

configuration = /usr/share/doc/pktanon/examples/profiles/profile-identity.xml istream: opened file profiles/sample.pcap ostream: opened output file out.pcap initialized complete

statistics for input file 'profiles/sample.pcap' processed packets: 9 errors in packets: 0

22us
0.409

The anonymized trace out.pcap will be created in the root directory of the distribution. If the output file already exists it will be trimmed and rewritten without any warning.
