Executive Summary
We want to try to port WireShark and see what we could get working on the BeagleBone.

As it was a problem to get wireshark compiled on the beaglebone after some skype sessions with Patrick Vogelaar, Graduate student in Advanced Communications at Napier in Edinburgh we thought of the problem in a different way. Instead of porting ressource consuming wireshark to the beaglebone we use tcpdump on the bone to just monitor the traffic. The traffic is tehn piped through ssh to the host computer and then analyzed by wireshark. So we get use the full capability of wireshark on a host computer and use lean tcpdump on the beaglebone.

Packaging
If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions
Hardware requirements: Beagle Bone Black Linux host computer USB cable Ethernet Cable

Software requirements: Wireshark installed on your host computer

sudo apt-get install wireshark

Getting the sources:

do a git clone on our repository to get all the sources you need

type make to build the binaries out of the code

type sudo ./run.sh to set everything up please look at our source code if you do not trust our code.


 * Include your github path as a link like this to the read-only git site: https://github.com/MarkAYoder/gitLearn.
 * Be sure your README.md is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
 * Include a Makefile for you code.
 * Include any additional packages installed via opkg.
 * Include kernel mods.
 * If there is extra hardware needed, include links to where it can be obtained.

User Instructions

Theory of Operation


This part is currently under construction ... so the information provided is not jet finalized ...

The beaglebone black is attached to ethernet. Tcpdump is running on the beaglebone in a special mode and listens to eth0. The beaglebone is connected with a host via ssh over the usb interface. All data captured by tcpdump is forwarded over ssh to the host computer. The host computer provides 2 named pipes so called fifos. All the ssh traffic is piped to the first fifo. The wireparser reads out of the fifo and filters non pcap stuff out. Then the filtered packages are piper to fifo2. Wireshark is started in a special mode to read out of fifo 2 and provides a graphical interface for analysis of the packets.

No matter that we are using very low ressource consuming tcpdump on the beaglebone we do have the capability for live captures and analysis of the networktraffic.

Work Breakdown
Job to do: Get wireshark running on the beagelbone black.
