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)
