NAME¶

pktanon - profile-based traffic anonymizer

SYNOPSIS¶

       pktanon [-c profile_file] input_file output_file


       pktanon [options] [input_file] [output_file]

DESCRIPTION¶

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.

OPTIONS¶

Configuration:

-c, --config <config_file>

anonymization profile

Input Parameters:

-s, --snaplen <number>

read first snaplen bytes from each packet (for both captures and files) [default:256]

-i, --interface <interface>

capture packets from this interface

-p, --no-promiscuous-mode

do not set interface in promiscuous mode

-e, --pcap-filter <filter>

filter specification for libpcap

-r, --use-raw-sockets

use linux raw sockets instead of libpcap (-e option is not available)

Output Parameters:

-U, --packet-buffered

output (to file) is flushed every N packets

-n, --network <interface>

send packets to <interface> using libpcap-inject (EXPERIMENTAL)

-o, --socket <Addr:Port>

send packets to Addr:Port using sockets

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

-6, --use-ipv6

Use IPv6

-u, --use-udp

Use UDP

Miscellaneous:

-l, --use-libpcap

use libpcap for file i/o

-h, --help, --usage

print this message and exit

-q, --quiet

Reduce output

-v, --verbose

Increase output

RUNNING PKTANON¶

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

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