PROGRAM:

NAME


dnspktflow - Analyze and draw DNS flow diagrams from a tcpdump file

SYNOPSIS


dnspktflow -o output.png file.tcpdump

dnspktflow -o output.png -x -a -t -q file.tcpdump

DESCRIPTION


The dnspktflow application takes a tcpdump network traffic dump file, passes it through
the tshark application and then displays the resulting DNS packet flows in a "flow-
diagram" image. dnspktflow can output a single image or a series of images which can then
be shown in sequence as an animation.

dnspktflow was written as a debugging utility to help trace DNS queries and responses,
especially as they apply to DNSSEC-enabled lookups.

REQUIREMENTS


This application requires the following Perl modules and software components to work:

graphviz (http://www.graphviz.org/)
GraphViz (Perl module)
tshark (http://www.wireshark.org/)

The following is required for outputting screen presentations:

MagicPoint (http://member.wide.ad.jp/wg/mgp/)

If the following modules are installed, a GUI interface will be enabled for communication
with dnspktflow:

QWizard (Perl module)
Getopt::GUI::Long (Perl module)
